Join ••••••'s development team as a Senior Agentic Engineer.
Responsibilities:
- Own features end to end: clarify problems with product, write specifications and acceptance criteria, build, test, ship, and support in production.
- Work across a new product surface and a large existing platform.
- Build an agent harness for your area, including context files, tests, hooks, and conventions for safe work in a legacy codebase.
- Create automated tests and evaluation loops to catch regressions before human review.
- Make scope and sequencing decisions, and write a workflow other engineers can adopt.
Requirements:
- 8+ years building and operating production software, including senior or lead experience owning outcomes.
- At least 6 months of daily agent-first workflow using Claude Code, Codex, Cursor agent mode, or similar, including running several agents in parallel.
- Ability to identify agent failures and catch them with tests, evaluations, small batches, and diff review.
- Experience with large, long-lived codebases, refactoring, migrations, and legacy constraints.
- Strong testing discipline, product judgment, security fundamentals, and experience handling sensitive data.
- Strong written English and at least 4 hours of daily overlap with US Eastern time.
- Core stack: Python, Django, .NET, Angular, Kotlin, Swift, AWS, and SQL. Adjacent stacks are acceptable.
Nice to have: Healthcare or HIPAA-regulated SaaS experience, multi-tenant B2B SaaS, agent tooling such as MCP servers, custom hooks, or evaluation harnesses, experience leading incremental legacy-platform migrations, and useful side projects.
