About Open Core Ventures "As software has eaten the world, open source is eating software." - Peter Levine Commercial open source software companies have captured hundreds of billions in enterprise value, yet this represents only a fraction of the trillions delivered by OSS today. We're still in the early innings. GitLab co-founder and executive chair Sid Sijbrandij started Open Core Ventures (OCV) to accelerate this opportunity. We start companies around promising open source projects, the same approach that took GitLab from OSS project to IPO in seven years. We recruit founders and help them reach escape velocity. We've started 30+ companies around open source projects, including Fleet , FlowFuse , and Mermaid Chart . You can read more about our approach in our public handbook . The Investor Role at OCV As an Investor at OCV, you'll identify and research promising open source projects and build investment cases. Unlike traditional venture investing, your job doesn't stop there. You'll launch these companies as interim CEO, working directly with technical founders to drive early growth. Think part investor, part co-founder. What You'll Do Source and evaluate open source projects for commercial potential, digging into codebase quality, architecture, contributor activity, and community traction to identify which projects could become venture-scale companies Identify and recruit CTO candidates directly from the maintainer and core contributor base of these projects Launch companies as interim CEO: define the initial product roadmap, ship the first version, land early customers or design partners, and run GTM until the company has real traction About You We're looking for 0-1 product managers, product-obsessed founders, or product-centric operators who can spot the next great technology and build it into a real company. You know how to talk to users, do things that don't scale, and build something people want. You could be a great investor at OCV if: You move fas

About the Team The Coding team is reimagining how software is built in the AI era. We build tools and workflows that help software engineers work faster, tackle more ambitious projects, and spend less time on repetitive tasks. AI has already transformed how code is written, but software engineering extends far beyond coding. Our mission is to apply AI across the entire software development lifecycle (SDLC) — from design and implementation to code review, testing, debugging, issue remediation, maintenance, documentation, and user support. The team is also responsible for developer-facing Codex experiences including the Codex IDE Extension and the terminal interface, which are used daily by developers ranging from individual open-source contributors to some of the world’s largest engineering organizations. The team also works closely with the open-source software community, building tools that help maintainers and contributors manage increasingly complex projects. We believe AI can make open-source development more sustainable by reducing the operational burden of reviewing contributions, triaging issues, maintaining quality, and supporting growing communities. By building the future of software development, we're helping advance OpenAI's mission of ensuring that the benefits of AI reach people around the world. About the Role We’re hiring a Full Stack Software Engineer to help invent the next generation of AI-powered software development workflows. “Full stack” in this role means much more than traditional frontend and backend development. You'll own complete product experiences, spanning user interfaces, workflow orchestration, agent and prompt design, backend systems, and cloud infrastructure. This is a highly product-oriented role. You'll work directly on the workflows developers use every day, identifying bottlenecks and rethinking how software gets built in a world where AI agents are active participants in the development process. The features you ship will inf
