We are Progress (Nasdaq: PRGS) - the trusted provider of software that enables our customers to develop, deploy and manage responsible, AI-powered applications and experience with agility and ease.
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 Experience
5+ years production
