- Drive capacity planning, performance tuning, and cost-efficiency across infrastructure, balancing reliability against operational spend
- Define and track SLOs/SLIs, and use them to prioritize reliability work against feature delivery
- Mentor other engineers; raise engineering and operational standards and strengthen both the systems you own and the people you work with

- Demonstrated experience in fintech or other high-stakes systems, including provider integration resilience, failover design, and compliance-sensitive infrastructure

- Strong communication skills, with the ability to work effectively across engineering, product, compliance, and external partners
