Job Description

Be part of the team building high‑throughput, low‑latency financial systems where correctness, reliability, and observability are non‑negotiable. You’ll work on core services that process time-sensitive financial data and execute critical workflows under strict performance and risk constraints.

• Design and build latency‑sensitive Rust services handling high‑frequency data and decisioning.
• Implement robust, testable financial logic with strict correctness guarantees.

• Optimize performance across CPU, memory, and network with profiling and benchmarking.
• Collaborate on API design, data models, and system architecture.

Qualifications

• A university degree in a relevant field of study (e.g. computer science, engineering, sciences, ...) or a comparable qualification.
• Extensive experience in our tech stack: Rust, Docker, AWS, Terraform
• Strong Rust proficiency (ownership, lifetimes, concurrency, async, error handling).
• Excellent systems thinking: latency, throughput, backpressure, and failure modes.
• Experience building high‑performance services in production.
• Experience with low‑latency systems.
• Strong analytical thinking, both in the technical and in the product domain.
• Excellent communication skills that are clear, concise, and targeted towards your audience - engineering, product, or other stakeholders.
• A passion for well architected, testable and documented code.
• Experience using coding agents (e.g., Codex or similar AI-assisted development tools) is a plus.
• Experience with domain-driven design and distributed architectures and/or microservices is a plus.
• Background in financial services and exposure to compliance or audit requirements in financial systems is a strong plus.
