Rust Engineer

Requirements:

• 3–6 years in backend or systems engineering, including Rust you’ve shipped and run in production (ownership model, async, concurrency, error handling)
• Background in trading technology (market data, venue connectivity, order management or execution) or in comparable messaging systems where reliability is non-negotiable
• Solid grasp of Linux, networking and how distributed systems behave when load spikes or components fail
• Proven ability to profile, measure and chase down hard-to-reproduce production bugs, backed by strong habits around testing, code review and documentation
• Fluent working English (German is a plus)

Responsibilities:

• Design, build and operate Rust services that ingest market data, connect to trading venues and route orders
• Engineer event-driven components that stay correct under pressure: ordering guarantees, backpressure, retries, deduplication and graceful recovery
• Integrate with venues, brokers and counterparties, handling sessions, reconnects and keeping trading state in sync
• Measure and tune for latency, throughput and resource efficiency, favouring predictable performance over chasing microseconds
• Cover business logic, integrations and failure modes with automated tests, and make services observable through metrics, logs and traces
• Shape large parts of the platform from a blank page: set priorities, document decisions, and work with infrastructure colleagues on releases and recovery
• Join the support rota and talk to customers occasionally

An investor-backed Swiss fintech, past its early stage and still growing, whose software supports financial institutions in their day-to-day operations. The Zürich tech team is small, so each engineer owns meaningful parts of the system and has a direct line into technical decisions. Collaboration happens mostly in person, communication is direct, and the working day has a clear end. AI-assisted development is part of the normal toolkit.
