The world's most important information is trapped in PDFs, scans, and files that can't easily be parsed, and getting it out correctly matters. From frontier AI labs processing training data to Fortune 500s like Siemens extracting decades of engineering records, Datalab is where businesses turn to when extraction has to be right. We’re at high 7-figure ARR. Anthropic, Legora, Booz Allen, and ElevenLabs are customers. And we have hundreds more across FAANG, frontier AI labs, healthcare, finance, government, and legal.

RDQ327R182 At Databricks, we are passionate about enabling data teams to solve the world's most challenging problems — from making the next mode of transportation a reality to accelerating medical breakthroughs. We do this by building and running the world's best data and AI platform, enabling our customers to use deep data insights to improve their businesses. Our ability to execute this mission depends on building trust and recognition within an ever-growing community of data engineers, analysts, scientists, machine learning practitioners, and AI practitioners. Are you a Developer Advocate who thrives in the spotlight, loves presenting and hosting events, and is genuinely hands-on with agentic developer tooling — the kind of person who has already wired up three coding agents and has opinions about what breaks? As a Senior Developer Advocate for Omnigent, you'll be a vital bridge between our engineering teams and the open source community forming around Omnigent, our meta-harness for AI agents. Omnigent sits one level above harnesses like Claude Code, Codex, Cursor, and Pi, giving developers a common interface to compose agents, govern them with contextual policies, sandboxing, and cost controls, and collaborate on live sessions from any device. Your focus is squarely on the open source project and the community around it: templates, demos, and reference implementations that developers can clone, fork, and extend, and the contributors who will help the project grow beyond us. This is a build-the-community role. Omnigent is early, and the people who adopt it now will shape what it becomes. You'll help developers integrate it into their own stacks, make it easy for new contributors to land their first pull request, and create the kind of momentum where the project's best advocates are people who don't work here. Your responsibilities will encompass a wide range of knowledge-sharing activities. You'll deliver engaging talks, host panels and meetups, create blogs

The Opportunity (Summer 2026 AI Internship - Applications Open Now) We're seeking an AI Engineer Intern to work alongside our AI team on large-scale AI and Agentic systems from data pipeline to production deployment. This role is scoped for someone with foundational experience who wants to deepen it: you'll own discrete pieces of real systems under the mentorship of senior engineers, not shadow work or isolated coursework-style projects. What You'll Do You’ll work directly with the AI team, taking responsibility for well-scoped pieces of real systems, with mentorship from senior engineers. Benchmarks & Evaluation Contribute to APIFlow-Bench , our open-source benchmark for real API-development work: design and review benchmark tasks and their mock API environments, extend the evaluation harness and task-generation pipeline in Python, and help maintain the public multi-model leaderboard with statistical confidence intervals. Help build a new action-level AI safety benchmark: instead of grading what a model says, it scores what an agent actually does inside a simulated enterprise API environment. You’ll work on scenari

The Open Core Ventures (OCV) Catalyst Program is a 3 month OSS project incubator aiming to support open source maintainers in the growth of their open source projects. Projects such as developer tools, artificial intelligence infrastructure/implementation, and data transformation (or any that solves a real problem and has potential for commercial viability) will be considered for Catalyst and will receive support and mentorship from OCV team. There is potential for top-performing projects to become OCV companies at the end of the program — 4/11 Catalyst projects became OCV companies, or their authors became OCV CTOs, in 2025. Participants in Catalyst will collaborate with OCV and their batch to establish and work towards clear, measurable objectives, focusing on metrics such as contributor growth, community expansion, and increased adoption. OCV provides $10,000 to support the growth of Catalyst projects, and it is not expected that authors work on their project full-time during Catalyst (most participants hold full-time positions while in Catalyst). OCV is committed to advancing the growth of open source through providing the sponsorship resources and aims to amplify the impact of open-source projects and position them for long term success. Eight project authors will be accepted Applications will be reviewed on a rolling basis and are due by June 28 , although may close sooner if all eight spots are filled. Catalyst v2 kicks off on July 14, 2026.

Supabase is the open-source Postgres development platform that 7M+ developers and thousands of enterprises depend on every day. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the role We’re hiring a Product Manager to own the platform primitives every Supabase product runs on, including internal features like compute , disks , networking, and the API gateway, and external features like read replicas , custom domains , PrivateLink , and Bring Your Own Cloud. What you'll be responsible for: Talk to customers across the full spectrum. Indie developers running a single nano project, fast-growing startups whose costs are dominated by compute and disk, enterprises walking through a network-architecture review, and partners building on top of Supabase. Find the real blockers and bring them back to the roadmap. Own the problem statement and requirements behind every platform bet. Capture the customer evidence behind each decision, name the cost, capacity, and reliability constraints, and give the team a target it can hit. Decide what gets built, what gets deferred, and what gets cut. Every quarter you're choosing between enterprise unlocks blocking deals, reliability and cost wins for the long tail of projects, and net-new capabilities that change what Supabase can run. Set the priorities and defend them. Define how each launch is measured before it ships. Set the metric, agree on the threshold, and track it after launch. Know whether a feature moved enterprise deal velocity, project economics, or platform reliability. Use that to sharpen the next call. Keep engineering, design, and leadership aligned. The platform touches every other Supabase product, every region, and every customer tier. Write the roadmap, surface dependencies before they become blockers, and keep decisions moving. You might be a good fit if you: Have 7+ years of produ
