Full Stack Engineer (Agentic Development)

About the role We're hiring a full stack engineer who builds with AI, not alongside it. You'll partner with a PM to take products from zero to one.

.NET and Angular are preferred, but we are looking for someone who mostly writes code using AI tools: Claude Code, GitHub Copilot, Cursor, Windsurf.

What you'll do

• Build new products end-to-end.
• Use agentic dev tools as your primary workflow - directing agents, not typing functions.
• Design AI agent systems with frameworks like Claude Agent SDK, OpenAI Agents SDK, or LangGraph: tool-calling, multi-step reasoning, memory, guardrails.
• Own the full stack: APIs, data, frontend, infra, CI/CD, monitoring.
• Make calls when specs are light, then validate with the PM.
• Ship to production and own uptime, cost, and performance.

Required

• 3-8 years shipping production software.
• Hands-on production use of agentic dev tools and at least one agent framework - we'll ask you to walk through what you've built.
• Cloud (Azure, AWS, or GCP), containers, CI/CD.
• Fluent English; comfortable working async.

Nice to have

• .NET (C#, ASP.NET Core, EF) and Angular.
• You've built and shipped your own product (side project, startup, OSS).
• Multi-agent orchestration experience.
• Azure ecosystem (Functions, App Service, AI Services).
• LLM cost management in production.
• Contributions to agentic frameworks or AI dev tooling.

Why join us

• Work from anywhere. Any location, your normal working hours, except for team syncs.
• An international team. You'll collaborate with engineers, PMs, and operators across multiple countries and time zones.
• Friendly, helpful colleagues.
• Team-building activities. Regular virtual get-togethers, sometimes in person depending on your location (if you are in a location where we have an office).
• No bureaucracy.
• AI-native by default. You'll work with the best agentic tools every day, not as a side experiment.

How to apply: Submit your resume along with links - shipped products, repos, or a write-up of a zero-to-one project. If you've built something with agentic tools, lead with that.
