About Us

Eulen.app, the company behind DePix (a privacy-centric stablecoin), builds products for the sovereign individual with a focus on security, privacy, and technical excellence. We are looking for a battle-tested, hands-on architect to become the guardian of our core production systems.

The Role

This is a deeply technical, hands-on position for a master craftsperson who prefers architecting and shipping brilliant code to attending meetings. As the technical owner of our high-volume core services, you will be the gatekeeper of quality, the champion of reliability, and the calm voice of reason during a crisis. Your mission: to ensure our systems run with unwavering stability and speed, enabling us to deploy frequently and safely.

What We Are Looking For (Required Qualifications)
  • 15+ years of working experience in critical, high-volume environments
  • Strong knowledge of backend programming (Rust, Go, C++, or similar)
  • Expertise in scalable and resilient architecture
  • Proven experience with automated testing and incident response
  • Background in designing and operating mission-critical systems
  • Excellent problem-solving and collaboration skills
  • Self-motivated, lifetime learner, aligned with Bitcoin ethos
Nice to have (Preferred Qualifications)
  • Experience with Bitcoin protocols (Liquid, Lightning)
  • Familiarity with compliance-aware architecture in fintech
  • Open-source contributions
  • Background in cryptography or financial systems
  • Previous startup or scale-up experience
Hiring Process
  1. September 19th (Friday) : Phase 0 begins. Instructions are sent at 00 : 00 BRT. This first challenge (via Google Forms) must be completed within 24 hours.
  2. September 20th (Saturday) : Candidates who successfully pass Phase 0 will receive instructions for Phase 1. This next stage, consisting of cultural and logical assessments, must be completed on this day.
  3. September 21st (Sunday) : Successful candidates from the previous stage will receive instructions for Phase 2. This final challenge, a specific technical deep-dive, must be completed on this day.
  4. Candidates who successfully complete all phases will be contacted to schedule a final interview, which may be conducted online or in person.

Join us to architect the backbone of Bitcoin payments, ensuring security, reliability, and technical excellence in a remote-first, high-performance culture.
