Desirable

• We are building high-throughput, low-latency financial infrastructure in Rust for core payment processing services. This role is focused on backend distributed systems, cloud-native services, and performance-critical APIs
• Design and lead the architecture of high-throughput, low-latency payment services written in Rust, handling thousands of requests per second with strict SLA requirements
• Own concurrency models, async execution strategies (Tokio-based systems), memory safety trade-offs, and performance profiling at the systems level
• Define service boundaries, event-driven contracts, and resilience patterns (idempotency, retries, backpressure, circuit breakers)
• Establish Rust engineering standards across the organization: crate selection policies, dependency management, error handling patterns, testing strategy, and production hardening
• Partner with Platform and SRE teams to design observability, structured logging, tracing, and metrics using OpenTelemetry
• Lead performance benchmarking, load testing, and capacity planning for Rust-based services

• Our Talent Acquisition team is invested in creating the best candidate experience possible, so don’t worry, you will definitely hear from us
• We will review your CV and keep you posted by email at every step of the process!
