Senior Backend Engineer — Real-Money Execution & Reliability

Xavvy Limited in the United Kingdom is seeking a trusted engineer to work on guardrails_engine, the executors, broker adapters, the scheduler—load-bearing, permanent full-time.

You should know Python, FastAPI, SQLAlchemy, Postgres at production scale, and Async scheduling with APScheduler or equivalent; you will own execution-path code with real financial impact.

Experience with broker/exchange API integration and debugging money-sensitive incidents is a strong plus.
