### Your Role: As a Site Reliability Engineer at Alpaca, you'll help keep our brokerage platform reliable, observable, and operable as we grow - working across our cloud infrastructure, Kubernetes platform, observability stack, messaging layer, and data layer. ### Things You Get To Do: - Operate production day-to-day - oncall, incident response, postmortems, and the follow-ups that actually close the loop. - Own reliability practice - define and refine SLIs/SLOs and error budgets, and help product teams live within them. - Strengthen our observability across metrics, logs, traces, and alerting. - Ship infrastructure through code in a GitOps workflow - cloud resources and Kubernetes workloads alike. - Look after PostgreSQL: performance tuning, schema and migration review, online migrations on large tables, HA/DR, and CDC pipelines. - Mentor engineers on reliability and database fundamentals through code review, design review, and pairing.

### Who You Are (must-haves): - 4+ years in SRE, DevOps, Platform/Infrastructure, or backend engineering with significant production operations ownership. - Hands-on experience operating production services on Kubernetes, and shipping infrastructure as code in a GitOps workflow. - Solid working knowledge of PostgreSQL in production — query plans, pg_stat_*, indexing and schema trade-offs, and what a safe online migration looks like on a non-trivial table. - Cloud networking fundamentals (VPCs, routing, L4/L7 load balancing, DNS, TLS) and comfort debugging cross-service connectivity. - Comfortable with a modern observability stack and proficient with Linux at the operator level. - Practiced in incident response - calm under pressure, structured debugging, postmortems that drive change. - At least working proficiency in Go or Python, plus strong written and verbal communication. - Genuine interest in databases and in growing your PostgreSQL/DBA expertise.

### How We Take Care of You: - Competitive Salary & Stock Options - Health Benefits - New Hire Home-Office Setup: One-time USD $500 - Monthly Stipend: USD $150 per month via a Brex Card. Alpaca is proud to be an equal opportunity workplace dedicated to pursuing and hiring a diverse workforce.
