We are looking for a Senior Systems Engineer with 10+ years of experience in systems-level engineering (Rust/C/C++), including 5+ years of production Rust, to design and build high-performance, low-latency, fault-tolerant trading infrastructure. Prior hands-on experience with financial trading systems is mandatory.Responsibilities

- Design, develop, and maintain high-performance backend services using Rust - Build scalable and reliable distributed systems capable of handling high request volumes - Optimize application performance, memory usage, and resource utilization - Design clean, maintainable, and well-tested software architecture
- Collaborate with product, engineering, and DevOps teams to deliver production-ready solutions
- Participate in architecture discussions, code reviews, and technical planning - Troubleshoot production issues and improve system reliability and observability - Write clean, well-documented, production-quality code following engineering best practices

Required Qualifications

- 10+ years of professional systems programming experience in Rust, C, or C++ (5+ years production Rust)
- Mandatory: hands-on experience with financial trading systems — exchanges, order books, matching engines, OMS/RMS, or market data systems (equities, F&O;, FX, commodities, or crypto)
- Strong understanding of exchange mechanics — order types, price-time priority matching, spot trading, derivatives (futures/perpetuals), options, margining and liquidation concepts
- Strong experience building production-grade, low-latency, high-throughput backend applications

- Experience working with relational databases and caching systems
- Experience working in Linux-based production environments
- Familiarity with containerization and modern deployment practices
- Strong debugging, profiling, and benchmarking skills (perf, flamegraphs, Criterion) - Excellent problem-solving and analytical abilities; ability to work independently and take ownership of technical deliverables

Preferred Technical Experience

- Tokio, Tonic (gRPC), Serde, Tracing, Criterion, Cargo/Clippy/Rustfmt - Aeron, LMAX Disruptor, Chronicle, or FIX engines
- Kernel-bypass networking concepts (io_uring, DPDK, AF_XDP); hardware timestamping
- Lock-free or wait-free programming techniques
- Options pricing / Greeks / volatility surface exposure

Preferred Qualifications

- Experience designing highly available and fault-tolerant systems (active-active, consensus-based failover)
- Deterministic simulation / property-based testing of stateful systems
- Exposure to cloud infrastructure and production monitoring tools
- Open-source contributions (openraft, TigerBeetle, tokio, etc.) or personal Rust systems projects
