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 new 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 Rust in systems software (runtimes, compilers, databases, or networking).
- Compiler or language runtime experience — at least one of: parser, AST/IR, bytecode compiler, VM, or interpreter.
- Async Rust at scale — Tokio, shared-state concurrency, cancellation safety.
- Large multi-crate workspace fluency.
- Ability to read large C codebases and derive correct Rust implementations.
- Mentorship mindset — patience, clear communication, progressive handoff.
- Long-term ownership orientation — multi-year commitment.
- Excellent written and verbal English.
- CS degree or equivalent (data structures, algorithms, OS, compilers)
Additionally, it would be beneficial if you have:
- VM design — opcode dispatch, cooperative scheduling, register allocation.
- Binary protocol reverse-engineering and zero-copy parsing.
- Property-based testing (proptest, quickcheck).
- Concurrent data structures — DashMap, Moka, lock-free patterns.
- Axum / Tower / WebSocket server experience.
- Developer tooling protocols (LSP, DAP).
- Observability — tracing, OpenTelemetry, Prometheus.
- Database connectivity — pooling, transactions, schema resolution.
- Experience onboarding engineering teams into Rust.
- AI-assisted development tools (Copilot, Claude).
If this sounds like you and fits your experience and career goals, we’d be happy to chat. What we offer in return is the opportunity to experience a great company culture with wonderful colleagues to learn from and collaborate with, and also to enjoy:
Compensation
- Competitive remuneration package
- Employee Stock Purchase Plan Enrolment
Vacation, Family, and Health
- 30 days of earned leave
- An extra day off for your birthday
- Various other leaves like marriage leave, casual leave, maternity leave, and paternity leave
- Premium Group Medical Insurance for employees and five dependents, personal accident insurance coverage, and life insurance coverage
- Professional development reimbursement
- Interest subsidy on loans - either vehicle or personal loans.
