This is a fully remote position, open to applicants in Estonia.

📋 Description

• Break down legacy monolithic systems into modular architectures that are readable by agents, ensuring strict boundaries and a clear single responsibility.

• Drive gradual modernization efforts utilizing the Strangler Pattern.

• Encapsulate legacy logic within modern, contract-driven interfaces.

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

• Design and sustain the agent context layer featuring standardized Skills, Rules, and Commands.

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

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

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

• Enforce test-driven development (TDD) and characterization testing practices.

• Supervise and enhance agentic reasoning loops for cost efficiency, speed, and architectural soundness.

⛳️ Requirements

• Over 7 years of experience in software architecture, platform engineering, or technical leadership.

• Demonstrated success in modernizing extensive, undocumented legacy systems.

• Strong hands-on proficiency with TypeScript, .NET, and Node.js.

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

• Practical knowledge of agentic development, MCP, LLM tooling, or AI-assisted engineering.

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

• 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 navigating high-ambiguity, high-ownership environments is beneficial.

🏝️ Benefits

• Remote-first work culture.

• High level of ownership, flexibility, and the opportunity for significant impact.

• Engage with a variety of products and technologies.

• Opportunities for growth across engineering, product, and leadership domains.
