Senior Rust Engineer — Production Backend Systems | Remote (LATAM)

Headquarters: Remote

URL: https://www.toptal.com/

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.
