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.\nRequirements\n3-6 years in backend or systems engineering, including Rust you’ve shipped and run in production (ownership model, async, concurrency, error handling)\nBackground in trading technology (market data, venue connectivity, order management or execution) or in comparable messaging systems where reliability is non-negotiable\nSolid grasp of Linux, networking and how distributed systems behave when load spikes or components fail\nProven ability to profile, measure and chase down hard-to-reproduce production bugs, backed by strong habits around testing, code review and documentation\nFluent working English (German is a plus)\nResponsibilities\nDesign, build and operate Rust services that ingest market data, connect to trading venues and route orders\nEngineer event-driven components that stay correct under pressure: ordering guarantees, backpressure, retries, deduplication and graceful recovery\nIntegrate with venues, brokers and counterparties, handling sessions, reconnects and keeping trading state in sync\nMeasure and tune for latency, throughput and resource efficiency, favouring predictable performance over chasing microseconds\nCover business logic, integrations and failure modes with automated tests, and make services observable through metrics, logs and traces\nShape large parts of the platform from a blank page: set priorities, document decisions, and work with infrastructure colleagues on releases and recovery\nJoin the support rota and talk to customers occasionally","description_format":"text","description_chars":1936,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All
