About Noumena

Noumena is an AI research lab and product company building toward AGI through narrow, adaptive intelligence. We’re building a platform that adapts to experts, starting with developers, and expanding into research, planning, and high-context decision-making.

By owning the full stack, from hardware to interface, we create coherent systems that evolve in deployment and specialize through use.

About the Role

You’ll help define how our intelligence platform interacts with code: through structured planning, adaptive refactoring, and real-time reasoning. Starting with developer workflows—PR planning, debugging, repo awareness—you’ll design the primitives that will generalize to other domains of expert work.

This isn’t autocomplete. This is co-architecture. And the systems you help build will become a model for what adaptive tooling can feel like.

TypeScript, Python, and Rust, used fluidly across interaction, orchestration, and performance-critical paths.

What You’ll Do

• Build structured, responsive workflows for expert developer tasks
• Prototype interaction patterns where LLMs plan, reason, and adapt
• Work across the stack to connect UI, runtime, and backend logic
• Collaborate closely with modeling and infra teams on agent design
• Define generalizable primitives that extend beyond software

You May Be a Good Fit If You:

• Have built IDEs, dev tools, or other structured developer environments
• Thrive at the edge of systems, UX, and product design
• Understand the flow of real developer work: not just the tools, but the thinking
• Care about creating high-trust, I-can’t-go-back experiences
• Love translating ambiguous workflows into deliberate systems

Bonus Points For:

• VS Code extensions, real-time editor integrations
• AST manipulation, prompt orchestration, or agent planning logic
• Repo-aware tooling (CI, PRs, branching logic, etc.)
• Designing for structured generation or multimodal UIs

Why This Role Matters

You’ll define the first set of workflows where Noumena’s intelligence meets real developer intent, and you’ll help architect the infrastructure that supports future domains. This is foundational product work for foundational users.

Team & Culture

We’re a small, senior team of researchers, engineers, and builders. We value deep ownership, curiosity, and deliberate thinking. We care about coherence, from silicon to syntax, and we move with quiet urgency.

We’re remote-flexible and invest in real-world time together, especially during pivotal build phases. We’re radically deliberate: open to experimentation, allergic to drift, and committed to systems that matter.

Location & Compensation

• Remote-flexible (with travel covered for quarterly in-person gatherings)
• Open to candidates spending time in the Bay Area during key build phases
• Includes meaningful equity: high-impact work means high ownership
