Senior Software Engineer (Backend/Fullstack)-Reliability Focused

Latin America | 100% RemoteAbout the RoleWe're looking for a senior engineer who can design, build, and operate production systems end-to-end. You'll work across our core stack building features and services, while also owning the reliability, observability, and performance of what you ship. You won't be handing your code off to a separate ops team — you'll be on-call for it, instrumenting it, and improving it based on how it behaves in production.What You'll DoDesign and build backend/fullstack features across Java 21, Spring/Spring boot, JPA/Hibernate, NodeJS, React/React NativeInstrument services with logging, metrics, and tracing (e.g., Splunk, Prometheus, Grafana, Datadog, OpenTelemetry) as a standard part of development, not an afterthoughtDefine and monitor SLIs/SLOs for the services you own; use error budgets to guide prioritization between feature work and reliability workParticipate in an on-call rotation; respond to and resolve production incidents affecting your servicesWrite and maintain postmortems/RCAs, and drive follow-up fixes to prevent recurrenceContribute to infrastructure-as-code (Terraform, CloudFormation, etc.) for the systems you buildPerform capacity planning and load testing for services ahead of scale eventsCollaborate with platform/infra teams on shared tooling, but take primary ownership of your service's healthParticipate in code reviews, architecture discussions, and mentor junior engineersWhat We're Looking For5+ years of professional software engineering experience, with deep expertise in Java 21, Spring/Spring boot, JPA/Hibernate, NodeJS, React/React NativeDemonstrated experience owning services in production — not just writing code, but debugging, scaling, and maintaining it liveComfort with observability tooling and reading dashboards/logs/traces to diagnose issues under pressureExperience with incident response processes (on-call, paging, postmortems)Working knowledge of cloud infrastructure with AWS and containerization (Docker, Kubernetes) — enough to reason about deployment and scaling, even if you're not a dedicated platform engineerStrong communication skills — you can explain a production issue to both engineers and stakeholdersBonus: experience with CI/CD pipelines, infrastructure-as-code, or chaos engineering practicesWhat This Role Is NotThis is not a dedicated SRE/DevOps/Platform Engineering role. You won't be building the observability platform itself or managing infrastructure for other teams — you'll be a strong practitioner of reliability engineering within your own feature work.What You’ll Love100% RemoteHolidays offPaid Time OffHealth insurance assistanceCompetitive USD compensationGrowth opportunities
