ABOUT THE ROLE

Developer Lead (Full-Stack) who takes ownership and stays highly hands‑on. You design, build, and ship key features end‑to‑end with minimal overhead, no endless alignment, and no “ping‑pong” back and forth. The focus is speed of execution, engineering accountability, and predictable delivery.

WHAT YOU'LL BE WORKING ON
  • Lambda‑first product on AWS Serverless: event‑driven workflows, reliability, observability, security.
  • Integrations: acquiring and banking rails, external providers.

DB, Aurora DB, full‑stack JS/TS.

WHAT YOU NEED TO SUCCEED IN THIS ROLE
  • 3+ years as a Lead (or equivalent ownership role with real accountability).
  • Strong full‑stack capability: confident across backend and frontend.
  • 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).
WHAT WE OFFER
  • An opportunity to make something great even greater, you can be the reason why we grow, develop, and become the best fintech company on the market!
  • Career prospects – we are young, we have huge ambitions, and it is important that our employees grow with us.
  • Work with coworkers who are passionate about their business.
  • Compensation that will fully correspond to the competence and knowledge, with yearly performance reviews.
  • The opportunity to attend conferences, courses, and professional development at the company's expense – we favor the continuous development of our employees.
  • Hybrid type of work.
