Stop paying for slow, memory-leaking backends. Ensigncode's Rust developers build systems that are fast by design — zero garbage-collector pauses, data-race-free concurrency, and compile-time safety guarantees that eliminate entire classes of production bugs.
Whether you need a single senior Rust engineer to rewrite a performance-critical service or a full squad to build a greenfield Rust platform, we match you with developers whose skills align with your technical stack. Our Rust engineers are production-focused, write idiomatic Rust from day one, and have shipped Rust systems that handle millions of requests per day.

Our Rust engineers write safe, zero-overhead systems code that outperforms equivalent C++ while eliminating buffer overflows, dangling pointers, and data races at compile time.
- Custom memory allocators, lock-free data structures, and arena-based allocations
- Operating system interfaces, Linux kernel module bindings, and syscall-level code
- High-performance parsers, serialisers, and binary protocol implementations
- Unsafe Rust auditing — reviewing, justifying, and minimising unsafe blocks in existing codebases
- Zero-copy data processing pipelines for terabyte-scale datasets
We build Rust-powered REST, gRPC, and WebSocket APIs that sustain hundreds of thousands of concurrent connections with sub-millisecond latencies — ideal for fintech, gaming, and real-time data platforms.
- Actix-web and Axum REST services with OpenAPI documentation and JWT authentication
- Tonic gRPC services with bi-directional streaming and server reflection
- Async connection pooling with SQLx, Deadpool, and bb8 for PostgreSQL, MySQL, and Redis
- Rate limiting, circuit breaking, and backpressure middleware with Tower
- Load-tested Rust APIs benchmarked against Go and Node.js alternatives — consistently faster
We compile Rust to WebAssembly to deliver near-native performance in the browser and on edge servers — replacing JavaScript bottlenecks in compute-intensive web applications.
- wasm-bindgen and wasm-pack integration for seamless JavaScript interop
- Yew framework for building reactive Rust-first web UIs compiled to WASM
- Edge compute deployments on Cloudflare Workers, Fastly Compute@Edge, and WasmEdge
- Rust-based game engines and simulations running at 60fps in browser via WASM
- Shared Rust logic between server and client — write once, run everywhere
Rust's no-std support and deterministic memory model make it ideal for bare-metal embedded systems where C has traditionally dominated. Our embedded Rust engineers ship firmware that is safer and easier to maintain.
- no_std Rust firmware for ARM Cortex-M, RISC-V, and ESP32 microcontrollers
- RTOS integration with RTIC (Real-Time Interrupt-driven Concurrency) framework
- Device driver development and hardware abstraction layers (HAL)
- Safety-critical firmware for automotive, medical, and industrial control systems
- OTA (over-the-air) update systems and secure boot implementation in Rust
We architect Rust-based microservices that are independently deployable, fault-tolerant, and capable of sustaining millions of events per second without the overhead of a garbage-collected runtime.
- Event-driven architectures with Kafka, NATS, and RabbitMQ consumers written in Rust
- Service mesh integration with Linkerd and Istio for Rust-based services
- Distributed tracing with OpenTelemetry and Jaeger across Rust microservice clusters
- CQRS and event sourcing patterns implemented in idiomatic Rust
- Health checks, graceful shutdown, and rolling restart patterns for zero-downtime deploys
Rust's zero-overhead FFI and deterministic memory layout make it an ideal systems layer for GPU-accelerated applications. Our engineers bridge Rust and CUDA for maximum throughput at minimum latency.
- CUDA bindings from Rust using cudarc and rust-cuda — safe wrappers around NVIDIA GPU kernels
- Rust-based data preprocessing pipelines feeding GPU inference workloads
- HPC scheduler integration (SLURM, PBS) with Rust-based job submission tools
- Multi-threaded Rust data pipelines with Rayon achieving near-linear CPU scaling
- Rust-powered inference servers wrapping ONNX and TensorRT models via C FFI
Rust's performance and memory safety profile make it the language of choice for blockchain core development. Our engineers have shipped production Solana programs and Substrate pallets.
- Solana smart contracts (programs) using the Anchor framework
- Substrate and Polkadot pallet development for custom parachain logic
- On-chain order books, AMM liquidity pools, and DeFi protocol engineering
- Rust-based indexers and on-chain data processors for blockchain analytics
- Cryptographic primitives — zero-knowledge proof systems and signature schemes in Rust
Migrating a legacy C or C++ codebase to Rust is the most impactful performance and safety investment many engineering teams can make. We make that transition incremental, safe, and measurable.
- FFI boundary design — calling Rust from C/C++ and vice versa without runtime overhead
- Automated memory-safety audits identifying UB, buffer overflows, and use-after-free patterns
- Incremental rewrite strategies: replacing hot paths first, driven by profiling data
- Flamegraph profiling, criterion micro-benchmarks, and Valgrind/ASAN comparison before and after
- CI pipeline integration with cargo-audit, cargo-deny, and Miri for continuous safety validation
Tell us about your project — systems programming, backend API, embedded firmware, WASM, blockchain, or GPU work. Share your preferred Rust edition, async runtime, and target start date. A 30-minute call is usually enough.
We send you a shortlist of pre-vetted Rust developers within 48 hours. Review GitHub profiles, open-source contributions, and benchmark results — then conduct a live Rust coding interview or architecture session.
Your Rust developer joins your Cargo workspace, attends standups, and begins shipping idiomatic Rust code from day one — fully embedded and following your clippy lint rules, CI pipeline, and code review process.

We are not a general-purpose staffing agency. Every Rust developer on our bench has shipped production Rust systems — and we only place engineers who write idiomatic, safe, well-tested Rust, not developers who just learned the language.

- GPU + Rust Intersection — uniquely, we combine Rust expertise with deep CUDA and GPU engineering, enabling Rust-based high-performance compute pipelines
- Full IP Ownership — all Rust source code, library crates, and documentation produced belong entirely to you, covered by a signed NDA from day one
- Timezone Flexibility — our Rust developers overlap with US (EST/PST), European (GMT/CET), and APAC business hours
- No Junior Padding — minimum four years of production Rust experience; we do not bill junior profiles as senior engineers
- No Long Lock-In — minimum two-week engagement; scale up or pause the team as your project requires
- Open Source Contributors — several of our engineers maintain or have contributed to crates on crates.io, including async utilities and embedded HAL implementations
- Post-Engagement Support — six weeks of bug-fix support included after every fixed-scope Rust delivery
