Ensure all releases comply with best practices (OWASP Top 10, SQL safety, authentication/permissions). Remain close to the product stream, shaping features that give clients confidence when trading. Requirements 5+ years of backend engineering with significant experience in crypto, fintech, or trading environments. Production experience in Rust is required. Proven track record building secure, client‑facing APIs. Strong knowledge of SQL and event‑driven systems. A product mindset—focused on “why” as well as “how.” Experience mentoring or leading small engineering teams. Pragmatic commitment to shipping high‑quality systems. Nice to Have Familiarity with trading workflows (orders, balances, settlements). Contributions to Rust or security‑related open‑source projects. Understanding of regulatory/compliance requirements for financial platforms. Benefits International environment (English is the main language). 50 % coverage of transportation costs and a sustainable mobility agreement. Swile lunch voucher (€9.25 per day, 60 % covered). 100 % Alan Blue coverage for you and your children. Wellpass contribution toward gym membership. Team events and off‑sites. Recruitment Process HR Call (30 min) – introduction and fit. Technical Interview with the Head of Engineering (90 min) – deep dive into technical background. Team Fit (60 min) – meet future teammates and learn about our working environment. Wrap‑Up Interview (45 min) – overview of Flowdesk culture. C‑Level Interview (30 min). We focus on conversations, not trick questions. These discussions help you understand Flowdesk’s workings and share your journey and expectations. We are committed to an inclusive and accessible recruitment process. If you require reasonable adjustments (e.g., sign language interpreter, extra time for a test, or an accessible location), please let us know. #J-18808-Ljbffr
