🌉 San Francisco, CA (On-site)
We are pioneering the future of AI alignment by building cutting-edge, scalable multiplayer environments where AI agents learn the fundamental skills of cooperation and competition. Our exceptional team brings together deep technical expertise and a powerful vision: to dramatically accelerate the success of top-tier ML researchers. Backed by world-class investors, we are assembling a cohort of driven individuals who want to do the most challenging and impactful work of their careers.
We’re looking for a Software Engineer who thinks like a scientist and operates like a founder. You’ll own entire systems end-to-end: from identifying what to build, to designing and implementing solutions, to measuring impact and iterating. This isn’t a role where you wait for specs; you generate clarity from ambiguity and ship with conviction.
Like us, you enjoy and engage in rich discussions with your teammates. You like exploring the future together, both learning from smart people around you and enriching them with what you find interesting as well.
You’re also fluent in modern AI tools and use them to multiply your output; we expect engineers here to be exceptionally productive, and to leverage that productivity toward bigger problems, not just faster typing.
Own products end-to-end. Define what to build based on user needs and business goals. Design the technical approach. Build it. Ship it. Measure it. Improve it.
Apply analytic rigor to feature decisions. Design experiments properly. Understand what your data can and can’t tell you. Avoid the traps that lead to false conclusions.
Move fast with quality. We ship frequently and learn from real usage. You’ll balance speed with craft, knowing when to take shortcuts and when to invest in foundations.
Leverage AI tools aggressively. We expect you to use AI assistants, code generation, and other tools to operate at 2-5x the productivity of a traditional engineer. This frees you to focus on harder problems.
Collaborate with a small, excellent team. We’re a small team of engineers who trust each other to do great work. Low process, high ownership, direct feedback.
Deep analytical background. Graduate work in a quantitative field (CS, physics, etc.), research experience, or equivalent depth from industry. You’ve done deep analysis, not just pulled numbers from dashboards.
Full-stack capability with multi-language strength. You’re comfortable across the stack; backend services, data pipelines, frontend when needed. You will move between Python, and C++.
Strong customer instincts. You understand why something should be built, not just how. You’ve shipped tools for developers and researchers, and you can articulate what made them successful.
AI-native workflow. You already use AI tools (Claude, Copilot, Cursor, etc.) daily and have opinions about how to use them effectively. You’re excited about how AI changes what’s possible for a small team.
Ownership mentality. You don’t need to be told what to do. You see problems, propose solutions, and drive them to completion. You’re comfortable with ambiguity and energized by responsibility.
We hire based on impact, not years of experience. Compensation reflects your expected contribution.
Organic alignment starts at home. We're an equal opportunity employer because diversity is a precondition for the kind of collective intelligence we're building toward.
