Member of the Technical Staff, Software Engineering

The Role

As a Member of the Technical Staff, you build the system that makes our agents good at security: the graph they reason over, the infrastructure they run on, and the agents themselves. There are no fixed lanes. In one week you might ship a new cloud integration, rework how the graph links an endpoint to the code that serves it, and tune an offensive agent so it chains two low-severity findings into a real exploit.

You'll work directly with the founders and a small team of engineers who ship to production every day, and who use coding agents as heavily as the customers we protect. You'll own problems end to end: talk to the customer, design the fix, ship it, and watch it run in production.

What You'll Do

• Build and extend the live security graph: crawlers that discover cloud, SaaS, and code resources, and the pipeline that turns them into a consistent model of a customer's production system.
• Design, evaluate, and improve AI security agents that pentest, triage, chain, and remediate findings, and build the evals that tell us whether they actually got better.
• Own services end to end across Go, TypeScript, PostgreSQL, graph databases, and AWS, from design through deployment and on-call.
• Make the platform safe to point at production: strict tenant isolation, egress controls, and secrets handling that customers' security teams will scrutinize.
• Work with customers and our security leads to turn real findings, misses, and false positives into product improvements.
• Set the engineering bar as we grow: code quality, review culture, tooling, and how we build with AI agents.

What We're Looking for

• Strong software engineering fundamentals and a track record of shipping and owning production systems end to end.
• Fluency in at least one of Go or TypeScript, and the willingness to work across the stack.
• Experience with distributed systems, data pipelines, or cloud infrastructure (AWS, GCP, or Azure).
• You build with AI coding agents daily (e.g., Claude Code, Cursor) and have opinions about how to make them reliable.
• Curiosity about how real systems break: you want to understand the attack, not just the alert.
• You own ambiguity: energized by defining how something works, not just executing a process.

Nice to Have

• Offensive security experience: penetration testing, red teaming, bug bounty, or CTFs.
• Experience building LLM agents, evals, or agent tooling in production.
• Experience with graph data models or graph databases (Neptune, Neo4j, Memgraph).
• Background in application or cloud security tooling (SAST, DAST, CSPM, SIEM).
• Prior early-stage startup or founding-engineer experience.

Compensation & Benefits

• Base salary: [PAY RANGE], depending on level and experience.
• Early-stage equity: you're joining early; you'll own a real piece of what we build.
• Comprehensive medical, dental, and vision coverage, and the equipment you need to do your best work.
• Based in San Francisco; we work in person.
