• Deep, production‑grade AWS experience and a serverless mindset.
• A builder mindset with daily AI usage: you rely on AI tools every day to simplify routine work, accelerate development, and deliver results faster (while keeping high engineering standards).
• Ability to execute end‑to‑end fast: architecture → implementation → code reviews → release → monitoring → iteration.
• Solid decision‑making, high ownership, ability to untangle complex integrations, and a systematic approach to improving product quality.
• English B2+ and higher (the team is English‑speaking).
