Senior Site Reliability Engineer

About EarnIn As one of the first pioneers of earned wage access, our passion at EarnIn is building products that deliver real-time financial flexibility for those with the unique needs of living paycheck to paycheck. Our community members access their earnings as they earn them, with options to spend, save, and grow their money without mandatory fees, interest rates, or credit checks. We’re fortunate to have an incredibly experienced leadership team, combined with world-class funding partners like A16Z, Matrix Partners, DST, Ribbit Capital, and a very healthy core business with a tremendous runway. We’re growing fast and are excited to continue bringing world-class talent onboard to help shape the next chapter of our growth journey. 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 delivering production-ready features to our community rapidly. 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 are 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 engineers' experience building them. This position will be remote from Mexico, with the possibility of being hybrid in our Mexico City office as part of our expanding site. EarnIn offers excellent employee benefits, including healthcare, internet and cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Mountain View headquarters. Our salary ranges are determined by role, level, and location. We are unable to provide visa sponsorship or immigration support for this position. 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 bachelors or masters degree in computer science or equivalent industry experience 4+ years of experience in an SRE or Software Engineering role. Hands-on coding experience in Python and/or Go. Distributed Systems Expertise — Proven experience designing, operating, and shepherding large-scale distributed systems from design through production, including incident learnings that make on-call quieter over time. Reliability Engineering Mindset — Deep fluency in SLOs, SLIs, error budgets, and MTTR — using them to drive decisions and explain tradeoffs, not just decorate dashboards. Observability & Incident Response — Treats observability as essential, not optional; stays calm under pressure; can diagnose incidents from logs and metrics and translate findings into durable process and technical improvements. Cross-functional Communication — Able to work across technical and non-technical teams, reduce silos through documentation and runbooks, and explain reliability concepts in plain language. Operational Tooling & AI Fluency — Selects the right tools for production management and leverages AI-assisted development to reduce toil, accelerate RCA, and streamline infrastructure-as-code workflows. Leadership & Mentorship — Can plan and lead strategic reliability initiatives across engineering, and invests in mentoring engineers as a high-leverage path to long-term reliability improvements. #LI-Remote At EarnIn, we believe that the best way to build a financial system that works for everyday people is by hiring a team that represents our diverse community.
