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.

- Solid understanding of distributed systems and concurrent programming - Raft/consensus, replication, snapshots, deterministic state machines, exactly-once semantics.

- Advanced concurrency : lock-free/wait-free structures, ring buffers, thread-per-core design, core pinning.

- Strong understanding of networking concepts - TCP/IP, UDP, multicast, real-time communication, asynchronous networking.

- Experience designing and implementing binary communication protocols for inter-service communication (SBE, Protocol Buffers, FlatBuffers, Cap'n Proto).

- Experience with microservices architecture and event-driven systems.

- Experience with messaging systems such as Aeron, Kafka, NATS, or similar high-performance platforms.

- Strong understanding of in-memory data structures and efficient memory management - cache lines, memory ordering, NUMA, allocation-free design.

- 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.

Selection Process :

- 3 Rounds of Technical Interview.

- 1 Round of Management Interview.

- Shortlisting based on work evidence (repo/PR/design doc/write-up of a hard problem solved).

- Systems design deep-dive (order book / matching engine design), hands-on coding round, distributed systems round.
