Senior Reliability Engineer

Join Hims & Hers as a Senior Reliability Engineer, where you'll be responsible for enhancing the reliability of our systems. You'll work on critical customer journeys, engineer for peak load and failure, build incident response as software, automate operational excellence with AI, and maintain tooling for Operational Excellence reviews. This remote-first position offers generous PTO, full healthcare coverage, retirement planning, and competitive compensation.

• Assurer la fiabilité des systèmes Hims & Hers en construisant des outils d'observabilité, d'automatisation et de détection des problèmes.
• Définir et instrumenter les SLOs, les signaux d'or et les moniteurs de niveau commercial pour les parcours clients critiques.
• Diriger le travail de capacité et de résilience pour les événements à enjeux élevés et la croissance en régime permanent.

• Strong software engineering fundamentals. You solve reliability problems by writing code and building tooling, and you're comfortable reading application code across the stack to find the real cause
• Daily, practical use of AI coding and analysis tools (Claude, Cursor, or similar) to accelerate investigation, code, documentation, and reporting, and clear judgment about when to trust the output and when to verify it
• Communication skills to explain risk, tradeoffs, and post-incident learnings to engineers and leadership alike, in writing and in review meetings
• Production experience with AWS, Kubernetes/EKS, Terraform, and PostgreSQL (RDS/Aurora)
• Hands-on depth in observability and SLO engineering: golden signals, burn-rate alerting, journey-level monitors, and turning noisy alert streams into actionable pages (Datadog preferred; Prometheus/Grafana and OpenTelemetry welcome)
• 5+ years as a Software, SRE, Platform, or Infrastructure Engineer, with a track record of owning reliability outcomes for production systems that customers depend on
• Experience running or maturing incident management end to end: on-call design, escalation policies, incident command, blameless post-mortems, and action-item follow-through in a tool like FireHydrant or PagerDuty
• We are committed to building a workforce that reflects diverse perspectives and prioritizes ethics, wellness, and a strong sense of belonging. If you're excited about this role, we encourage you to apply—even if you're not sure if your background or experience is a perfect match
• Experience building AI agents or LLM-backed automation for operations: incident triage, RCA generation, alert correlation, or observability data analysis, ideally with MCP or tool-calling integrations against Datadog, FireHydrant, or Jira
• Familiarity with service mesh (Istio) and its observability and traffic-management features
• Background in a regulated or healthcare environment, where reliability and data handling carry patient-safety and compliance weight
• Load-testing and performance-engineering experience at meaningful scale (k6 or similar), including validating systems to well above expected peak
• Experience designing vendor and partner escalation frameworks with defined severities and response SLAs
