- Design, build and run scalable, secure backend services and APIs for trading, market data and portfolio features.
- Own larger features and services end to end, including monitoring, alerting and on-call follow-up.
- Design for correctness first: accurate money and quantity handling, idempotent requests, safe retries and audit trails.
- Keep services fast and stable at market open and during peak volume, and plan capacity ahead of known events.
- Integrate with exchange, clearing, bank and other external systems, and make those integrations resilient to failure.
- Lead design reviews and give thoughtful code reviews.
- Investigate production incidents, run root cause analysis and ship lasting fixes.

- Data & Messaging: Hands-on with relational and NoSQL databases (query tuning), caching (Redis) and messaging (Kafka).
- Infrastructure: Experience running services on cloud platforms (GCP or AWS), with containers and CI/CD.
- Mindset & Domain: Ownership mindset and clear communication. Experience in capital markets, brokerage, payments or another regulated, high-traffic environment is a strong plus.
