Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.
This is not a reinvention: it’s a reflection of how we already serve our customers today.

Being able to ask questions to an LLM copilot about patterns across several billion rows, 140GB of time series data, like how the market reacts 15 minutes, 1 day, and 1 week after Federal Reserve press releases, using time_bucket() and other aggregation functions with compressed chunks, and having the copilot generate the queries and run them fast, is going to be game changing. I can ask to write a script to scrape the press releases, to run them through another agent to classify them (hawk, dove) and use that information in the time series analysis.
Even though that exploration has not produced any actionable, tradable results for me, which is why I am sharing it, eventually TimescaleDB will be one of the most important tools in fields like medical research. A researcher will be able to ask in natural language for statistically significant patterns in the data, and LLM agents will query it quickly while taking advantage of all the TimescaleDB optimizations.

Count is an infinite, real-time canvas where SQL, Python, and low-code query cells live side-by-side with visualizations and freeform whiteboarding. It replaces the traditional linear notebook with a collaborative space for modeling, analysis, and presentation.
Under the hood, we've built a custom WebGL rendering engine, data visualization library, graph-based modeling layer, and horizontally scalable compute engine (DuckDB-based) that dynamically shifts execution between browser and server to minimize latency and reduce database load.
You'll help evolve the core platform: integrating agentic workflows into data exploration, pushing the performance limits of our distributed execution layer, and building powerful new analytics experiences used daily by customers. You'll have high autonomy and ownership over major parts of the product and technical roadmap, from architecture through production.
Tech stack: TypeScript, Python, Node.js, WebAssembly, WebGL, Apache Arrow/Parquet, DuckDB, Kubernetes, React.

I applied and got rejected without feedback. They stated that there was a high volume of strong applicants (if there were, why are they posting again?)
This is the case for the vast majority of companies posting jobs here and elsewhere (e.g., LinkedIn) right now. I've been looking for the past 7 months after a lay-off and that exact reply is the most common response I've seen (because it's an automated response). Well, most common after not hearing back at all, of course.

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)
* A well designed API first approach; one customer compared our APIs to petrichor

I'm founder of Vidably and just closed a $1.5M pre-seed last week.
AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.
We're already seeing organic pull from creators and expansion from brands.

You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing.

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!
Our products:
* Merge Queue: Ensure your PRs keep the builds you care about green at any scale.
*Flaky Tests: Detect and eliminate Flaky Tests.
Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions
Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs.

Here at Hearst we've been building out generative AI use cases and fluency across our portfolio of businesses spanning well known media brands to healthcare, transportation, and financial services. While we are an established corporation with multi-national presence, the mission and support behind our generative AI team more closely resembles a well-funded early stage startup as we engage in radical business transformation empowered by nascent technology.
The ideal candidate is one who has written code but now builds systems largely leveraging agentic development tools such as Claude Code (w/ Opus 4.5) & Codex (w/ GPT-5.2), and who sees the future of development as managing swarms of AI agents rather than cranking out code by hand.

Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing constantly. The information to diagnose most issues already exists, but finding it takes longer than fixing the problem. And the more AI-generated code ships, the more services get deployed by people who won't be around to debug them.
Cleric connects to your existing observability stack, autonomously investigates production incidents, and tells engineers what's wrong. We're well funded with years of runway, a small team of AI and infrastructure veterans in SF, growing quickly. Stack: Python, Go, LLMs, Kubernetes.
Some of the problems we work on:
There's no test suite in production. When the AI says "the root cause is X," how do you verify that? You can't A/B test diagnoses. Ground truth labels don't exist. We build evaluation systems that track resolution outcomes over weeks and correlate fixes with diagnoses to build statistical confidence.
When something breaks, everything looks broken. Database latency spikes, five services throw errors, CPU goes up, logs explode. When an agent sees 47 anomalies at once, it needs to figure out which one is the root cause and which are symptoms, across systems with feedback loops, hidden dependencies, and non-obvious temporal relationships.
A single investigation might need six hours of metrics across 50 services, 10GB of logs, 10,000 distributed traces, the last 30 deployments, and the relevant runbooks. LLMs have finite context windows. What's relevant isn't known until you investigate. Getting retrieval wrong means wrong conclusions or exploding costs.
We're hiring:
- Staff Software Engineer, AI: You build the core agent. Reasoning, evals, self-improving feedback loops. You debug agent behavior by tracing reasoning and tool choices to understand why the agent made a specific decision. You build the systems that make a non-deterministic agent reliable, and push it to handle increasingly complex incidents.
- Staff Software Engineer, Product: You define what an AI SRE should actually be. When AI handles the reasoning, how do engineers stay sharp for cases it can't handle? How do you build trust when someone needs to verify agent conclusions at 2AM? You answer these by embedding with customers during real incidents, running experiments, and making the technical calls to ship what works.
- Software Engineer, Backend: You build and scale the investigation platform alongside our senior engineers. Integrations with Datadog, PagerDuty, and dozens of observability tools. Agent reasoning pipelines. Runtime systems that handle real-time data streaming at scale. You'll ship customer-facing functionality across the stack.
- Founding Marketer: Software engineers are allergic to AI hype. Our users already love the product. The challenge is reaching the next thousand teams without setting off their BS detectors. You build the marketing function from scratch: programs, pipeline, infrastructure. You need a technical foundation and the ability to hold a 30-minute conversation with a platform engineering lead without getting lost.
- Staff Designer (Remote): The interfaces for AI agents don't exist yet. How do you make autonomous reasoning legible without overwhelming? You own design across brand, product, and marketing, defining the visual language for a new category.

We’re hiring an Enterprise AE to scale Parabola, a product used by finance and ops teams to automate messy, high-stakes workflows without needing engineers.
Parabola sits at the intersection of AI, automation, and real operational pain: unstructured data (PDFs, emails), brittle processes, constantly changing rules, and teams that can’t wait months for IT. Customers get to see live workflows in action immediately.
This is not a traditional enterprise sale... Deals are driven by automations, as they are built live in-app. Customers engage multiple times per week and see value instantly. Expansion is natural because the product is horizontal, the first team is never the last
We’re looking for someone who loves going deep on product and customer problems. You can work comfortably with operators and execs (CFO/COO) as well as with companies in the retail/ ecom/ CPG + freight/ logistics spaces. You care deeply about solving real problems. We're building the Enterprise motion, not just running a playbook.
Parabola had its biggest year ever in 2025. We’re consistently exceeding targets, and there is serious demand that is pulling us upmarket. You’d be working closely with our CRO, COO, CEO and GTM team to shape how Enterprise sales is done here. If you’re an experienced AE (5+ years in SaaS sales) who wants to sell something genuinely powerful with real customer impact, we’d love to talk.

Web scraping hasn't changed in decades: engineers still write brittle scripts that constantly break. Kadoa automates the entire web data pipeline with AI agents that build, maintain, and validate scraper code themselves.
All 3 founders have spent years in the trenches writing web scraping and ETL software and still do it almost every single day. We’re making sure every team member can do the best work of their career at Kadoa.
We are growing fast, have a drama-free and distraction-light environment, and try to minimize the distance between the code you ship and the customers who use it.
We are looking for people who share our passion for software craftsmanship, web scraping, and AI.
Open roles:
- Senior Frontend Engineer: https://www.kadoa.com/careers/frontend-engineer
- Senior Software Engineer: https://www.kadoa.com/careers/senior-software-engineer
If that sounds like you, please email me at (adrian at kadoa dot com) and mention HN in the subject line.
We're building an open source AI image and video crafting tool, aiming to take on the likes of Adobe, Figma, Blender, and more.
The tool is similar to AI aggregator tools like FreePik, Higgsfield, etc., but we're making our tools open source and we undercut middle-men aggregators with strong BYOK / "login with" components. Our founding team consists of filmmakers, VFX engineers, and people passionate about the field.
To apply: email brandon@storyteller.ai or join our Discord. Mention HN. Strong bias for candidates that enjoy film and video, so please share your YouTube, Vimeo, or IMDB if you have one.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
