• Uphold SOLID principles, Dependency Injection, and Hexagonal Architecture.

• Design and oversee the agent context layer encompassing Skills, Rules, and Commands.

• Create and manage Model Context Protocol (MCP) servers that transform legacy APIs, services, and databases into secure, AI-compatible tools.

• Take ownership of contract-first API design that bridges human intent and autonomous agent execution.

• Serve as the architectural gatekeeper for AI-generated pull requests.

• Enforce test-driven development (TDD) and characterization testing during the refactoring process.

• Extensive hands-on knowledge of TypeScript, .NET, and Node.js.

• Strong foundation in API design, distributed systems, and modular architectures.

• Practical experience with agentic development, MCP, LLM tooling, or AI-assisted engineering.

• A preference for clean code, deterministic systems, and production-level AI.

• Experience with remote-first or globally distributed teams is a plus.

• Background in SaaS transformations, scale-ups, or private equity-backed environments is advantageous.

• Comfort in high-ambiguity, high-ownership environments is desirable.

• Availability to work during US morning hours.

• Must be located in Eastern Europe.


🏝️ Benefits

• Fully remote work opportunity from Eastern Europe.
