You Will

• Own the architecture and write core low-latency code across Syncro (Rust).
• Cut latency by design: validator submission path, network routing/peering, node co-location, direct QUIC/TPU ingress.
• Cut latency in code: optimal algorithms and data structures, tight time/space complexity, language- and OS-level performance (memory layout, allocations, cache, syscalls, lock-free concurrency).
• Lead multi-region rollout on bare-metal and cloud, co-located near client trading venues.
• Eliminate single points of failure with HA and automatic failover.
• Automate safe, self-serve releases; own latency/uptime SLOs, observability, and alerting.
• Set the technical bar through design and code review.

You Have

• 8+ years building distributed backend/infrastructure, with low-latency systems shipped to production.
• Write highly efficient code—algorithms and data structures, time/space complexity, and language-runtime + OS-level performance (memory, cache, allocations, syscalls, concurrency).
• Deep Solana internals—validator/TPU, stake-weighted QoS (SWQoS), QUIC, shreds, transaction landing. (Priority)
• Trading / MEV / market-data infrastructure—orderflow, searchers, latency-sensitive paths.
• Expert in a systems language—production Rust (or C/C++/Go moving to Rust).
• Networking and latency tuning—TCP/QUIC, routing, peering, co-location, kernel/NIC tuning.
• Production infrastructure—Linux, bare-metal and cloud (GCP/AWS), Kubernetes, IaC.
• PostgreSQL; RabbitMQ/Kafka in HA.
• Owned a complex system's architecture end-to-end.
• English C1+; remote, async.

Nice to Have

• Solana validator operations / staking infrastructure.
• MEV ecosystem—relayers, bundles, block engines.
• SUI, Hyperliquid, or other high-throughput chains.
• Real-time market-data / streaming systems at scale.
• Low-level profiling and benchmarking (perf, flamegraphs).
• Blockchain open-source contributions.

Benefits

• Fully remote.
• Full-time contractor (Indefinite-term Consultancy Agreement).
• Competitive salary level in USD (crypto payment also available).
• Paid vacation and sick leave.
• Well-being program.
• Mental Health care program.
• Compensation for education, including foreign language and professional growth courses.
• Equipment and co-working reimbursement program.
• Overseas conferences and community immersion.
