Senior Infrastructure Engineer

Who you are

• You have 5+ years of hands-on cloud or infrastructure engineering experience, with substantial time spent on reliability and production operations at scale
• You have defined SLIs and SLOs for real production services, and can talk about what changed as a result. What got fixed, what got deprioritized, and what you got wrong the first time
• You have hands-on experience with an observability platform in production; Datadog strongly preferred
• You're comfortable writing code (Python, Go, TypeScript, or similar) for internal tooling, production debugging, and automation
• You write production Terraform and are comfortable in AWS, and when production breaks you can find the problem and fix it
• You have built or operated a disaster recovery plan: you set the recovery goals, wrote the failover and restore steps, and ran the drills that proved it works
• You have been on-call for services you helped build, and you have opinions about what makes an alert worth waking someone for
• You prefer giving teams paved roads and good defaults over mandates, so they can own their own instrumentation
• You have led a reliability or observability modernization project where you defined the vision, approach, and delivered the implementation
• You have built internal tooling, libraries, or instrumentation standards that made it easier for other teams to operate their services well
• You have run game days, chaos experiments, or DR exercises, and fixed the problems they uncovered
• You have cut observability spend while keeping the coverage you needed

What the job involves

• We're looking to expand our Cloud Infrastructure team with a Senior Infrastructure Engineer, SRE to lead the reliability and operational evolution of our platform
• We run hundreds of services in production, which enable us to process billions of transactions, consume multiple terabytes of data, and produce hundreds of millions of logs per day, and our reliability practice needs to evolve to match our growing scale
• Building and improving the reliability and resiliency of our systems and services
• Establishing SLIs, SLOs, and error budgets for our most critical services and user journeys, and reviewing them regularly with the teams that own them
• Owning and evolving our disaster recovery strategy: recovery objectives, failover and restore paths, and regular exercises that prove they work
• Partnering with product engineering teams so they can own and operate their own services, with metrics that reflect real user experience
• Evolving our observability platform and standards across metrics, tracing, and logs: including instrumentation paved roads, alert quality, and observability cost
• Strengthening our incident practice: tuning paging thresholds, keeping runbooks current, and following through on postmortem action items
• Contributing to day-to-day Cloud Infrastructure work alongside your reliability specialty — infrastructure build-outs, platform backlog, and a shared on-call rotation (1 week out of every 6 weeks)
• You'll join the Cloud Infrastructure team and partner with engineering and internal support teams to drive this work
• We support millions of people to improve their financial lives, and this role ensures we can continue to do so reliably and at scale
