🎯 Your mission

  • Turn broad and sometimes ambiguous product requirements into simple, scalable technical solutions with minimal hand-holding.

  • Take end-to-end ownership of complex features, services, or product areas from design through production.

  • Drive and defend architecture and design decisions, including APIs, schemas, service boundaries, failure modes, scalability, and cost.

  • Identify technical trade-offs and choose pragmatic solutions that balance product needs, engineering quality, and long-term maintainability.

  • Use AI agents such as Claude Code, Cursor, or Copilot to plan, implement, test, and refactor solutions.

  • Break down complex work into tasks that AI agents can execute effectively and run multiple workstreams in parallel when appropriate.

  • Review and verify AI-generated code before it reaches production, including testing edge cases, security implications, performance, and overall quality.

  • Maintain strong engineering and architectural standards across an AI-assisted codebase.

  • Debug production issues across services using telemetry and observability tools, and drive issues through to resolution.

  • Collaborate closely with Product Managers, Designers, DevOps, and QA to shape solutions, not just implement requirements.

  • Help influence technical direction within the product area through sound engineering decisions and practical architectural thinking.

  • Quickly adapt to unfamiliar technologies and ecosystems when required.

  • Communicate technical decisions, trade-offs, and progress clearly, and take ownership of outcomes.

📌 You should have

  • Strong experience as a Senior Software Engineer, with a solid understanding of software engineering fundamentals and the ability to operate independently on complex problems.

  • Strong knowledge of TypeScript/Node.js.

  • Experience with React/Next.js.

  • Strong understanding of APIs, networking, databases, distributed systems, and security.

  • Hands-on experience designing APIs, schemas, and service boundaries for scalable systems.

  • Experience with both relational and non-relational databases.

  • Proven ability to work independently with ambiguous requirements, identify trade-offs, and make sound product and technical decisions.

  • Experience taking ownership of larger technical areas and influencing architecture beyond individual features.

  • An AI-native approach to development — using coding agents as a core part of your daily workflow, not just occasionally as an accelerator.

  • Strong verification and code-review discipline: you read diffs, test generated code, and understand its edge cases before merging.

  • Ability to quickly move between technologies and programming languages when needed.

  • English: C1+

💡 Why join us

  • 100% remote work.

  • Long-term cooperation in an international environment.

  • A modern AI-first engineering environment.

  • High level of autonomy and ownership.

  • Opportunity to influence architecture, technical decisions, and product outcomes.

  • Work with modern technologies and AI development tools.

  • Private medical care

  • MultiSport card
