Our requirements

  • 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+
