Principal Software Engineer - Rust Systems

Responsibilities

• 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
