This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Engineer, Syncro based in Spain.

This is a high-performance engineering role focused on building and optimizing ultra-low-latency infrastructure for blockchain and distributed systems at institutional scale. You will sit at the core of a high-throughput execution and validation environment, where every microsecond matters and system design decisions directly impact network performance and yield outcomes. The role combines deep systems engineering with real-world production responsibility across globally distributed infrastructure.

You will work on critical data paths, validator interaction layers, and transaction routing logic in a highly performance-sensitive Rust-based environment. The team operates at the intersection of distributed systems, networking, and blockchain protocol engineering. This is a hands-on role for engineers who thrive in complex, high-stakes technical environments and want to push the boundaries of latency and reliability.

Accountabilities

Architect and develop core Syncro components in Rust, focusing on ultra-low-latency execution paths

Optimize end-to-end transaction and validator pipelines, including routing, networking, and co-location strategies

Continuously reduce latency through algorithmic improvements, memory optimization, cache efficiency, and lock-free concurrency patterns

Design and operate multi-region, high-availability infrastructure across bare-metal and cloud environments

Eliminate single points of failure and ensure robust failover mechanisms across critical systems

Own system observability, performance metrics, SLOs, and production alerting for latency-sensitive workflows





Drive automation of safe deployments and continuous delivery for high-risk infrastructure components

Lead technical design reviews and set engineering standards for performance-critical systems

Requirements

8+ years of experience in distributed systems or infrastructure engineering with production-scale ownership

Strong expertise in low-level performance optimization, including memory management, concurrency, and system-level tuning

Deep experience with Rust or other systems programming languages (C/C++/Go with transition to Rust preferred)

Strong understanding of networking protocols and latency optimization (TCP, QUIC, routing, peering, kernel/NIC tuning)

Experience with distributed infrastructure across cloud and bare-metal environments (AWS/GCP, Kubernetes, IaC)

Background in high-performance or real-time systems such as trading, MEV, or blockchain infrastructure is highly valued

Solid experience with system design ownership, from architecture through production operations

Strong English communication skills and ability to work in distributed, asynchronous teams

Benefits

Competitive compensation in USD, with optional crypto payment

Fully remote, general working environment

Flexible contractor arrangement with long-term collaboration potential

Paid vacation and sick leave

Health, wellness, and mental health support programs





Budget for learning, education, and professional development (including language training)

Home office equipment and co-working reimbursement

Access to international conferences and community events

High-impact engineering work at the forefront of blockchain infrastructure
