Agentic Software Developer

What You'll Do * Use AI agents as integral tools for exploration, debugging, and code generation-moving fast through iterative prototyping and testing to find what works best.

* Test - build automated test pipelines and tools to ensure that AI generated outputs meet functional and performance standards.

* Design and implement core runtime components in a highly performant and secure environment.

* Collaborate across product, systems, and AI initiatives to expand runtime capabilities-enabling deeper visibility, control, and intelligence within running workloads.

* Prototype and productionize interfaces where AI systems interact safely with low-level software (e.g., introspection hooks, event streams, telemetry). * Drive projects end-to-end: design, build, test, deploy, measure, and iterate.

* Contribute to our engineering culture of curiosity, rigor, and technical excellence.

* Work primarily in-office from our South Park / SOMA location, collaborating closely with a small, deeply technical team.

What You'll Bring * You have 1-5 years of software engineering experience-or you're a strong recent graduate-ideally with exposure to systems or runtime development like compilers, instrumentation, observability, distributed systems, or optimizing performance-critical code paths * Strong proficiency in Go and/or TypeScript, with a deep understanding of performance, concurrency, and systems fundamentals.

* Comfortable using AI and agentic systems to move fast-balancing experimentation with sound engineering judgment on when to trust the tools and when to dig in yourself.

* Experience deploying production software in cloud-native environments (Docker, Kubernetes, modern CI/CD, Terraform/Pulumi). * Excellent collaboration and communication skills; comfortable in a fast-moving, low-ego engineering culture.

Nice to Have * Experience with Claude Code.

* Background in observability or introspection tooling.

* Interest in how AI can enhance system visibility, security, or automation.

Why You'll Love Working Here * Work on cutting-edge runtime technology at the intersection of security, observability, and AI.

* Collaborate with an experienced, thoughtful team that values deep technical understanding and craftsmanship.

* A collaborative, in-person environment in the heart of San Francisco's South Park / SOMA district.

* The opportunity to shape how modern developers build, ship, and secure software in the AI-accelerated era.

Compensation * $100,000 - $200,000 USD / year (depending on experience and qualifications). * Equity and benefits available.

* Non-elective 401k contributions.
