Senior Rust Systems Engineer: Cross-Platform FFI Lead

• Integrate Rust (Cargo-based workflows) into the existing CMK (custom Make) build system so Rust shared libraries (.so/.dll) compile, link, and ship alongside 200+ C subsystems across Linux x86_64 and Windows 64-bit
• Design and standardize Rust ↔ C FFI architecture, including: Extern "C" boundary design, Auto-generated C headers (via cbindgen), Error-handling conventions, Memory ownership and lifetime rules
• Establish Rust as a first-class, supportable language within the core database engine
• Design and deliver production-grade Rust shared libraries that replace legacy C implementations, including: Compression: A Rust-based zstd-backed compression library, JSON Parsing: A memory-safe, multi-threaded Rust JSON parser, Avro Serialization: A foundational Avro encode/decode layer
• Own benchmarking, validation, and parity testing to ensure Rust replacements meet or exceed legacy performance and stability
• Architect and lead a Rust-based platform systems layer replacing System V IPC with modern, cross-platform primitives (mmap, POSIX shared memory, futex-style synchronization)

Requirements Overall 10+ years of Software Engineering Experience Must have 5+ years of production Rust in systems-level software — database engines, OS components, embedded systems, network infrastructure, or similar Strong C/C++ background — ability to read, understand, and interface with 10,000+ files of C code daily; you need to think fluently in both languages FFI expertise — production experience with Rust ↔ C interop: extern "C", cbindgen/bindgen, unsafe boundary design, and memory-ownership protocols across language boundaries Shipped shared libraries — experience building .so/.dll Rust libraries consumed by C/C++ callers in production environments Build system integration — experience integrating Cargo with non-Cargo build systems (Make, CMake, Bazel, or custom frameworks) Multi-platform development — Linux x86_64 and Windows 64-bit at minimum Experience implementing software using OS fundamentals: file-system and storage management, memory management, virtual memory, process synchronization, and multithreading Strong problem analysis and solving skills; works independently and meets tight deadlines Excellent verbal and written communication skills in English Mentorship / tech-lead experience — you will be training a team, not just writing code A degree in Computer Science or equivalent foundational experience covering data structures, algorithms, operating systems, and database fundamentals ATS Optimization Keywords Below are skills and terms extracted directly from this job posting to improve Applicant Tracking System (ATS) visibility.
