What We Offer

• Real ownership and influence on what you build;
• Mentorship from experienced Rust and DeFi developers;

• Competitive compensation (based on level and contribution);
• Long-term growth path – from builder to architect, from contributor to leader.
• Remote-first, flexible schedule, high-trust culture.

How to Apply

We don’t ask for great CVs or endless experience lists.
What matters most is how you think and learn.

Our process is simple:

1. fixed time 2-hours test – built to reveal how you reason, solve problems, and learn new patterns.
2. 1-hour call – to discuss your results and how you approach challenges.
3. Meet with C-level – to explore how we can grow together.
