Senior Site Reliability Engineer (SRE)

POSITION SUMMARY

We have a real passion for delivering the best product experience for our community members. We work closely with all teams and share responsibility for rapidly delivering production-ready features to our community. We build or contribute to infrastructure, reliability tooling, and practices that help teams ship quickly and safely. We think a lot about things like good alert hygiene, friendly runbooks, clear SLOs, and how to make deployments feel boring in the best possible way. As a Senior SRE, you'll be  a technical leader in how we design, observe, and operate our systems in production. Rather than tuning kernels all day, you focus on how services behave as a whole: reliability, performance, failure modes, and the experience of the engineers who build them. EarnIn provides excellent employee benefits, including healthcare, internet/cell phone reimbursement, a learning and development stipend, and opportunities to collaborate with and travel to our Palo Alto HQ and Bangkok Site. Our salary ranges are determined by role, level, and location.

WHAT YOU'LL DO

• Design systems with resilience, graceful degradation, and capacity in mind.
• Define and measure SLOs and SLIs that actually reflect what our customers feel.
• Use Datadog (logging, metrics, APM) together with CloudWatch to build signal-heavy, noise-light observability.
• Configure alerting and routing that reach engineers through incident.io, where we run incident management and on-call, so that when a human gets paged, it really matters. 
• Continuously improve our incident lifecycle, from fast detection and solid triage, through clear communication, to blameless, actionable follow-ups.
• You will combine strong software fundamentals with reliability thinking so our systems are highly available, easy to debug, and a joy to work on. You know that the only good 2 a.m. alert is the one that never fires in the first place.

WHAT WE'RE LOOKING FOR 

• A master's or bachelor's degree in computer science or a related field, or related experience
• 4+ years of experience in an SRE or Software Engineering role.
• Successfully managed production environments at scale and understand that you need more than a for-loop to make it happen.
• A strong belief that observability is critically important to run highly available and performant services, not an optional nice-to-have.
• Experience using SLOs, SLIs, and KPIs to guide decisions, prioritize work, and explain tradeoffs, not just decorate dashboards or slide decks.
• You've read (or written) part or all of the SRE book and contextualized it for different engineering teams and cultures, rather than treating it as a one-size-fits-all checklist.
• Proficiency in leveraging AI productivity tools (e.g., Cursor, Claude Code) and prompt engineering to reduce operational toil, accelerate incident root cause analysis, and optimize infrastructure-as-code workflows
• Hands-on experience shepherding services from design to production, through incident learnings, and into a state where on-call actually gets quieter over time.
• Experience tackling site-wide outages, learned the lessons, and know how to turn those lessons into concrete, technical, and process changes that make it much harder for the same problem to happen again.
• Passion for mentoring engineers and a belief in the investment of people as one of the highest leverage ways to improve reliability and reduce toil
