Platform Engineer

What You'll Do

• Own core infrastructure — Databases, AWS services, networking, CI/CD; the systems every engineer depends on
• Build for scale — Thousands of concurrent AI operations, sub-second response times, cost-effective under load
• Design observability that works — System-level errors AND business-level silent-failure detection; we find out something is broken from an alert, not from a person hours later
• Orchestrate agentic workloads — N parallel agent instances doing non-deterministic work, running reliably and cost-effectively as N grows
• Multiply developer velocity — The tooling and abstractions that let product engineers ship in days instead of weeks
• Own reliability end-to-end — SLOs, on-call, incident response, and the post-mortems that make it rarer next time
• Build the eval infrastructure — Systems that measure whether AI outputs are getting better, not just running

Requirements

• Software engineering experience with a platform, infrastructure, or SRE focus (level determined during interviews)
• Proficiency in Python, TypeScript, Go, or similar
• Production experience with cloud infrastructure (AWS), databases (Postgres), and observability tooling
• Track record of building systems and tooling that other engineers depend on
• Based in San Francisco or willing to relocate

Nice to Have

• Experience orchestrating AI/ML workloads at scale (agent frameworks, LLM inference infrastructure)
• Voice AI or real-time systems experience
• Deep AWS experience (ECS, Lambda, RDS, VPC design)
• Prior startup experience—especially at companies that scaled through hypergrowth
