Senior Software Engineer, Server Networking Security (Rust)

About the Role

As a Senior Software Engineer on the Server Ingress Security team, you will be instrumental in rearchitecting MongoDB Server’s ingress networking to enhance security. You will design and implement production-ready security services in Rust, focusing on performance and operational excellence while collaborating with various teams to ensure seamless integration.

Candidate Profile

• 5+ years of experience building production-quality systems software.
• Experience with large backend/compiled codebases and performance-sensitive software, preferably in Rust.
• Bonus points for experience working hands-on in security-sensitive or networking-adjacent domains.
• Strong systems fundamentals, including multi-threaded programming and performance profiling.
• Understanding of network protocols, TLS, and connection lifecycle management.
• Familiarity with security concepts such as attack surface reduction, input validation, memory safety, and defense-in-depth architectures.
• Excellent verbal and written technical communication skills, with a strong desire to collaborate with colleagues.
• Strong time management skills and the ability to realistically assess project complexity.
• B.Sc. in Computer Science or a related field, or equivalent practical experience, with strong competencies in data structures, algorithms, and software design/architecture.

Position Expectations

• Design, implement, and operate production-ready security services in Rust, with a focus on security, correctness, performance, and operational excellence.
• Develop ingress networking and security solutions that ensure the security, availability, and performance of a database service.
• Diagnose test failures and performance regressions, and implement fixes.
• Lead development and project management for features and initiatives within the Ingress Security domain.
• Collaborate across Server, Atlas, Drivers, SRE, and Product Security teams to ensure the Atlas Network Protection layer integrates seamlessly with the broader MongoDB ecosystem.
• Collaborate with Product Management and Engineering leadership to define the team's roadmap.

Success Measures

• In the first month: Understand the high-level architecture of the Atlas Network Protection layer, set up your development environment, and resolve a few bugs.
• In three months: Contribute substantially to the Rust development of a current project or milestone, take on code review responsibilities, and participate in reviewing designs for new features.
• In six months: Independently lead the development of a new feature and help mentor new engineers on the team.
• In twelve months: Drive significant improvements to the security, performance, or operational capabilities of the Ingress Security stack, and contribute to the long-term technical roadmap of the team.
