Staff Engineer, Syncro

This is a fully remote position, open to applicants in Europe.

📋 Description

• Take charge of the architecture and develop the essential low-latency code across Syncro (Rust).

• Reduce latency by design: validator submission path, network routing/peering, node co-location, direct QUIC/TPU ingress.

• Minimize latency in code: implement optimal algorithms and data structures, ensuring tight time/space complexity, and focus on language and OS-level performance (memory layout, allocations, cache, syscalls, lock-free concurrency).

• Lead the implementation of multi-region rollouts on bare-metal and cloud platforms, strategically located near client trading venues.

• Remove single points of failure by utilizing high availability (HA) and automatic failover mechanisms.

• Automate secure, self-serve releases; take ownership of latency and uptime service level objectives (SLOs), observability, and alerting processes.

• Elevate the technical standards through design and code reviews.

⛳️ Requirements

• 8+ years of experience in building distributed backend/infrastructure, specifically with low-latency systems delivered to production.

• Demonstrate proficiency in writing highly efficient code — focusing on algorithms and data structures, time/space complexity, and language-runtime plus OS-level performance (memory, cache, allocations, syscalls, concurrency).

• In-depth knowledge of Solana internals — including validator/TPU, stake-weighted QoS (SWQoS), QUIC, shreds, and transaction landing. *Priority.*

• Experience in trading, MEV, and market-data infrastructure — covering order flow, searchers, and latency-sensitive paths.

• Expertise in a systems programming language — preferably production Rust (or C/C++/Go transitioning to Rust).

• Proficiency in networking and latency tuning — involving TCP/QUIC, routing, peering, co-location, and kernel/NIC tuning.

• Familiarity with production infrastructure — including Linux, bare-metal and cloud environments (GCP/AWS), Kubernetes, and Infrastructure as Code (IaC).

• Experience with PostgreSQL; RabbitMQ/Kafka in high availability (HA) setups.

• Proven track record of owning a complex system's architecture end-to-end.

• Proficient in English (C1+); remote and asynchronous work environment.

🏝️ Benefits

• Competitive salary in USD (with the option to receive payment in cryptocurrency).

• Paid vacation and sick leave.

• Well-being program.

• Mental health care program.

• Compensation for educational pursuits, including foreign language and professional development courses.

• Equipment and co-working reimbursement program.

• Opportunities to attend overseas conferences and engage with the community.
