About the Role

We’re looking for Senior Rust Engineers to take real ownership of a high-performance, production backend. You’ll be working on mission-critical systems where performance, security, and reliability aren’t nice-to-haves — they’re the job. Whether the work is hardening core services for a cybersecurity product or extending a Rust-based backend that powers a cross-platform application, this role is for someone who can navigate complex, unfamiliar codebases quickly and start shipping production-ready code fast.

What You’ll Do

• Build, optimize, and maintain high-performance backend services in Rust

• Take ownership of core backend architecture, including remediating vulnerabilities and improving CI/CD workflows

• Interface with PostgreSQL for complex data management, persistence, and schema-oriented design

• Design and work with schema-oriented service patterns (e.g., gRPC) where applicable

• Deploy and maintain services on AWS

• Jump into an existing, unfamiliar codebase and reach full productivity within the first 1–2 weeks

• Submit clean, high-quality code that holds up to rigorous review and peer scrutiny

• Take increasing ownership of backend direction as the system evolves or transitions from a legacy team

What You Bring

• Expert-level or extensive senior-level experience with Rust in a production environment

• Strong experience with PostgreSQL and SQL database design

• Strong experience with AWS for hosting and deployment

• Proven track record on large-scale, mission-critical, or high-stakes systems where performance and reliability matter

• Experience working as a senior individual contributor on evolving production systems

• Ability to explain complex architectural decisions and take full ownership of submitted code

• Comfortable working independently and ramping quickly on unfamiliar codebases

Nice to Have

• Familiarity with GitHub-based development workflows

• Experience with gRPC or Avro-based schema design

• Exposure to Flutter-based product environments (web, mobile, or desktop)

• Comfort using AI-assisted coding tools (e.g., Claude) without sacrificing code quality

RATE: $35-$45/hr.
