[Hiring] Senior Site Reliability Engineer @Alpaca

Role Description

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. We're especially interested in candidates with strong PostgreSQL fundamentals who'd like to grow into deeper ownership of our database reliability posture.

• 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.

Qualifications

• 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.

Requirements

• Deeper PostgreSQL experience: large clusters at OLTP load, online migrations on big tables, HA/DR ownership, connection pooling at scale, or change-data-capture pipelines.
• Experience with typed SQL access layers in Go (e.g. pgx, gorm, sqlc).
• Production experience with messaging systems at scale (e.g. RabbitMQ, Kafka, Redpanda).
• Security & compliance experience in a regulated environment (SOC 2, secrets management, audit logging).
• Familiarity with trading, brokerage, or other regulated fintech domains.

Benefits

• 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
