Senior Agentic Engineer

We are looking for an experienced Senior Agentic Engineer who works agent-first and owns features from problem to production, with no handoffs. You will be among the first engineers on our team working this way. We measure you on working software shipped and its quality, not on lines of code, PR count or tokens used.

Important: Candidate must be available to overlap with the US Eastern Time (ET) time zone for at least 4 hours per working day.

Responsibilities

• Features end to end: clarify the problem with product, write the spec and acceptance criteria, build, test, ship and support in production.
• Both new and old code: one bounded new product surface, plus changes inside our large existing platform. Not greenfield only.
• The agent harness for your area: context files, tests, hooks and conventions that let agents work safely in a legacy codebase.
• Verification: automated tests and eval loops that catch regressions before human review. Reviewers are not your safety net.
• Scope calls: cutting, sequencing and pushing back when the outcome can be reached more simply.
• Your playbook: a written workflow other engineers can adopt.

Requirements Core:

• 8+ years building and operating production software, including time as a senior or lead who owned outcomes, not tickets.
• Agent-first daily workflow for 6+ months (Claude Code, Codex, Cursor agent mode or similar), including running several agents in parallel. You default to agents and write code by hand only as an exception.
• You can show where agents fail and how you catch it: tests, evals, small batches, diff review. Evidence over enthusiasm.
• Deep work in a large, long-lived codebase: refactors, migrations, legacy constraints.
• Testing discipline. You write the tests that make agent output trustworthy.
• Product judgment: you have talked to users, written specs and cut scope to ship.
• Security fundamentals and experience handling sensitive data (health, financial or personal).
• Our core stack: Python, Django, .NET, Angular, Kotlin, Swift, AWS, SQL. Adjacent stacks are acceptable if everything else is strong.
• English proficiency at Upper-Intermediate (B2) level or higher.

Nice to Have:

• Healthcare or other HIPAA-regulated SaaS.
• Multi-tenant B2B SaaS.
• Built agent tooling yourself: MCP servers, custom hooks, eval harnesses.
• Led an incremental (strangler-fig) migration off a legacy platform.
• Side projects you built and still use.

We offer:

• Hybrid/remote work
• Flexible working hours
• Official employment
• Corporate football team
• Paid professional development courses
• English classes with our in-house teacher
• Opportunity to propose and implement your own ideas and see them come to life.

If you enjoy experimenting with AI coding agents, solving complex engineering challenges, and building reliable products that make a real impact, we’d love to hear from you!
