- Establish the engineering bar for system design and code quality as the team scales, mentoring future hires.
What You Bring
- 5+ years shipping production software, consistently owning features from concept to deployment, and acting as a go-to engineer for complex problems.
- Expertise in Type Script and comfort across the stack; productive in Python for integration with the core simulation engine.
- Deep understanding of full-stack performance: browser rendering, API latency, caching, concurrency, and debugging across the entire system.
- Advanced database skills (preferably Postgres), including indexing, query optimization, and zero-downtime schema migrations.
- Proven experience designing scalable architecture, defining service boundaries, and establishing robust API contracts.
- Fluency with AI coding agents (e. g., Claude Code, Codex) to accelerate development while maintaining high code quality standards.
