Senior Backend Engineer
Delphi Ventures
Job description We’re looking for a backend engineer. Someone who foresees the embedded risks and complexity of every "simple" feature, then writes and tests code as if it’s their mother’s life‑support system. Your PRs have made the blind to see, the deaf to hear, and contain the answers to Bob Dylan’s Blowin’ in the Wind. If you carry around a proof for P ≠ NP in your back pocket, please reach out. Job responsibilities Architect backend features, develop them in Rust, test rigorously, submit PRs, review PRs. Your PRs should indicate a thorough understanding of the whole problem (no "guestimate solutions") and an internalization that your code will go straight into production. Code should follow best practices, which you should already be intimately familiar with. Best practices referring to e.g. Clean Code by Robert Martin. Your work is done with memory management, time/space complexity, and security in mind. #J-18808-Ljbffr
