Opis stanowiska

🎯 Your mission
• Turn broad product requirements into simple, scalable technical solutions with minimal hand-holding.
• Take ownership of features, services, or product areas from design through production.
• Make and defend architecture and design decisions, including APIs, schemas, service boundaries, failure modes, and cost.
• 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, and overall quality.
• Maintain strong engineering and architectural standards in an AI-assisted codebase.
• Debug production issues across services using telemetry and observability tools.
• Collaborate with Product Managers, Designers, DevOps, and QA.
• Quickly adapt to unfamiliar technologies and ecosystems when required.
• Communicate technical decisions 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.
• Strong knowledge of TypeScript/Node.js.
• Experience with React/Next.js.
• Good understanding of APIs, networking, databases, distributed systems, and security.
• Hands-on experience designing APIs, schemas, and service boundaries.
• Experience with both relational and non-relational databases.
• Proven ability to work independently with ambiguous requirements and make sound product and technical decisions.
• 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.
