We are hiring a Senior Software Engineer to join our Server Security team. The Server Security team is a development-focused group within MongoDB's core engineering organization. Operating "close to the bottom of the stack," the team builds features that enable database users to secure their data globally. You will work on critical components including:

• Cryptography: Queryable Encryption, at‑rest data encryption, and fundamental cryptographic principles.
• Identity & Access: Authentication and authorization systems, TLS, and X.509 certificate management.
• Network Security: High-performance, low-latency networking protocols (PKI, Hashing, CRLs).
• System Integrity: Resilience, observability, and compliance assurance within a large-scale distributed database.

Our team champions a robust culture of inclusivity, diversity, and collaboration. If you want to work on a collaborative team that applies distributed systems fundamentals to deliver core features of a popular database, join us! Let’s change what’s possible for application developers, system architects, and database operators.
