  • Mentorship: Provide technical guidance to junior developers and foster a culture of knowledge sharing.
  • Problem Solving: Analyze complex technical problems and propose effective, production-grade solutions.

Requirements

  • Technical Expertise: Strong professional experience with TypeScript and Node.js .

  • Seniority: Extensive professional experience in a senior or lead-level backend role.
  • Infrastructure: Solid understanding of document databases (MongoDB), caching mechanisms (Redis), and system architecture.
  • Testing: Strong knowledge of testing frameworks and a proactive mindset toward quality assurance.
  • Communication: Exceptional written and verbal English skills; ability to work autonomously in a remote-first environment.
  • Education: A Bachelor's or Master's degree in Computer Science is a plus.
  • Bonus: Experience with Stellar's Soroban smart contracts.

Benefits & conditions

  • Compensation: Salary range of 90K - 130K EUR per year.
  • Time Off: 30 days of PTO.
  • Flexibility: Flexible working hours and remote days.
  • Equity: Participation in the company equity plan from Day 1.
  • Team Culture: Annual team offsites (previous locations include Thailand, Vietnam, and Marrakech).
  • Equipment: Entitlement to a work computer (your choice of equipment).
  • Growth: An annual €1,000 personal development budget (after 6 months of tenure).
