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","description_format":"text","description_chars":4207,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Cybersecurity","Science & Engineering"],"lifecycle":[{"event":"open","at":"2026-09-10T22:46:34Z"}],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.503,"p_room":0.35,"age_days":54,"expected_fill_days":24,"reasons":["conf:8","win:tail"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/orioninnovation-rust-systems-engineer","json_url":"https://alion.io/job/orioninnovation-rust-systems-engineer.json","meta":{"generated_at":"2026-10-02T03:26:46Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4772,"day_limit":5000,"remaining_today":228,"minute_limit":60,"resets_at":"2026-10-03T00:00:00Z"}}}
