Orion delivers game-changing business transformation and product development rooted in digital strategy, experience design, and engineering, with a unique combination of agility, scale, and maturity. We work with a wide range of clients across many industries including financial services, professional services, telecommunications and media, consumer products, automotive, industrial automation, professional sports and entertainment, life sciences, ecommerce, and education.\nJob Overview:\nWe are seeking a high-caliber Rust Systems Engineer to design, build, and optimize high-throughput, low-latency backend systems and infrastructure. In this role, you will go beyond web APIs-tackling low-level performance bottlenecks, complex state management, parallel compute algorithms, and concurrent data processing pipelines.\nIf you thrive on deterministic memory management, zero-cost abstractions, and writing safe, blazingly fast concurrent systems, this role is for you.\nKey Responsibilities:\nHigh-Performance Architecture: Design and implement zero-cost, high-throughput, low-latency engine components and data processing pipelines in Rust.\nConcurrent & Thread-Safe Systems: Build thread-safe, lock-free, or fine-grained locked data structures and state machines capable of scaling across multi-core architectures without race conditions.\nPriority & Real-Time Threading: Design custom thread pools, task schedulers, and execution queues with priority-based task scheduling and resource allocation controls.\nAlgorithmic Optimization: Implement complex computational logic, including high-efficiency recursive algorithms, tail-call optimizations, and dynamic cache-friendly data structures.\nResource & Memory Management: Leverage Rust’s ownership model, lifetime annotations, custom allocators, and non-blocking I/O to achieve predictable low-latency profiling (minimizing allocations and cash misses).\nSystem Profiling & Benchmarking: Conduct continuous benchmarking (criterion), flame graph analysis, memory profiling (Val grind/heap track), and CPU SIMD/vectorization optimizations.\nKey Skills:\nCore Rust & Functional Programming:\nAdvanced Rust Mastery: Deep experience with Rust internals (stdsync, stdcell, custom Drop, unsafe Rust boundaries, and macro systems).\nClosures & Higher-Order Functions: Mastery of Rust’s functional traits (Fn, FnMut, FnOnce), capturing environments, move semantics within closures, and passing unboxed closures for zero-cost abstractions.\nAdvanced Recursion & Tree Processing: Ability to structure complex recursive functions, tree/graph traversals, and dynamic programming patterns efficiently while preventing stack overflows (e.g., using explicit stack vectors or trampoline patterns).\nSystems & Concurrency Engineering\nThread Safety & Sync Primitives: In-depth understanding of memory models, cache coherence, atomic operations (AtomicBool, AtomicPtr, CAS), memory ordering (Acquire/Release/SeqCst), Send/Sync traits, and synchronization primitives (Mutex, RwLock, mpsc/crossbeam channels).\nPriority Threading & Scheduling: Practical experience implementing or customizing task schedulers, thread priority assignment, work-stealing thread pools, and priority queues (Binary Heap, custom priority locks).\nHigh-Performance Computing (HPC): Experience writing data-intensive, low-latency software. Knowledge of cache alignment, SIMD vectorization, memory-mapped files (mmap), and lock-free/wait-free data structures.\nGeneral Systems Knowledge\nSystems Architecture: 5+ years of software engineering experience, with 3+ years writing production-grade Rust (or a strong C/C++ background transitioning into production Rust).\nPerformance Analysis: Proficiency with profiling tools (perf, Flame graphs, Criterion, Coz) and debugging async execution (tokio-console, tracing).\nNice to Have\nExperience with custom memory allocators (jemalloc, mimalloc) and bare-metal/no-std Rust environments.\nKnowledge of asynchronous runtime architectures (Tokio internals, reactor/proactor patterns, custom Future implementations).\nFamiliarity with hardware-level optimizations (cache line padding, false sharing avoidance, NUMA-aware architectures).\nExperience with cross-language FFI (e.g., C/C++ interop or WebAssembly bindings).\nWhat We Offer\nHigh-Impact Architecture: Work on core engine infrastructure where microsecond-level performance and stability directly drive system success.\nModern Engineering Culture: Strong focus on code quality, explicit safety boundaries, comprehensive test suites, and strict CI/CD benchmarking.\nCompetitive Package: Competitive salary, equity options, flexible/remote working arrangements, and continuous hardware/learning allowances\nOrion is an equal opportunity employer, and all qualified applicants will receive consideration for employment without regard to race, color, creed, religion, sex, sexual orientation, gender identity or expression, pregnancy, age, national origin, citizenship status, disability status, genetic information, protected veteran status, or any other characteristic protected by law.\nCandidate Privacy Policy\nOrion Systems Integrators, LLC and its subsidiaries and its affiliates (collectively, “Orion,” “we” or “us”) are committed to protecting your privacy.
