We’re proud to have a diverse, global team where we value the individual and enrich our culture by considering varied perspectives because we believe people power progress. Join us as a Principal Rust Engineer and help us do what we do best: propelling business forward. Know more about us.
We are building a production language runtime in Rust — compiler, virtual machine, wire protocol client, and application server. You will join as a long-term technical owner of this system, working alongside experienced platform architects and a second FTE Rust engineer.
In this role, you will:
Runtime & VM
- Implement and optimize an async register-based virtual machine with cooperative scheduling and built-in function dispatch.
- Translate language semantics from a reference C implementation into idiomatic, correct Rust.

Compiler
- Extend a multi-stage compiler pipeline (lexer, parser, AST, IR, codegen).




- Deliver recent language features end-to-end with conformance and property-based tests.

Protocol & Data Layer
- Extend a binary wire protocol implementation reverse-engineered from C source.
- Own TLS, authentication, and connection pooling.

Async & Networking
- Maintain a Tokio-based async runtime handling thousands of concurrent requests with shared state and admission control.
- Contribute to HTTP, WebSocket, and gRPC server layers.

Engineering & Build
- Manage a large multi-crate Cargo workspace — dependency hygiene, CI performance, and release engineering.

Team Enablement
- Mentor senior engineers (20+ years platform experience) adopting Rust — teaching-oriented code reviews, pair programming, and progressive ownership handoff.
- Document architecture decisions and maintain design docs as first-class deliverables.

Your background:
- Overall 10+ years of Software Engineering
