About the role
- Stratus is a ~100-person, primarily remote, Series B software company growing quickly.
- Unrelenting Reliability is one of our company values, and this is the role that operationalizes it.
- You will define what reliable means in numbers, instrument the system so we can see it, and close the loop from production signal back into engineering priority.
Responsibilities
- Define and own service level indicators, objectives, and error budgets for customer-facing services; build the measurement pipeline that makes them trustworthy and publish availability and latency against target on a regular cadence.
- Establish and run incident response practice - on-call rotation and paging paths, severity definitions, per-system incident ownership, escalation into and out of customer support, and blameless post-mortems in incident.io.
- Lead performance and capacity engineering: query and index tuning, connection-pool sizing, capacity modeling against real load, and designing for graceful degradation under partial failure.
- Drive production readiness: review new services and significant changes against readiness criteria covering instrumentation, alerting, failure modes, resource limits, and rollback before they ship.
- Contribute to business continuity and disaster recovery planning, including backup and restore validation, failover design, and recovery objectives.
- Partner with engineering pods to push reliability ownership outward - coach teams on instrumenting and operating their own services.
Requirements
- 6-8+ years of professional engineering experience, with 3-5+ years in a dedicated SRE or production engineering role at a B2B SaaS company.
- Demonstrated ownership of SLOs and error budgets in production - you have defined them, measured them, argued about them with product leadership, and changed engineering behavior with them.
- Deep, practical observability skills with Prometheus, Loki, Tempo, and Grafana or comparable: you have instrumented real systems and built alerting that pages on customer impact rather than on CPU.
- Experience with load and performance testing tooling (k6, JMeter, Gatling, or comparable) and with turning results into engineering priority.
- Production experience on Azure or AWS, with real understanding of the failure modes of managed services.
- Fluency with AI-assisted engineering tooling and a track record of designing AI-leveraged workflows for your team - this is a graded expectation at every level at Stratus.
Nice to have
- Experience establishing or maturing an SRE practice - defining the discipline, not inheriting it.
- Experience with Sentry or comparable application error-monitoring platforms.
- Experience operating event-driven and real-time systems - message brokers (Azure Service Bus, Kafka) and websocket or push layers (SignalR or comparable).
- Experience operating MongoDB Atlas at production scale, including replica set topology and Atlas performance tooling.
- Experience with durable workflow orchestration (Temporal or comparable).
- Experience with incident.io, PagerDuty, or comparable incident management platforms.
- Familiarity with DORA metrics and with reliability work inside SOC 2 or NIST 800-171 scope.
- Experience with legacy monolith reliability - improving the operational behavior of an ASP.NET or comparable application you cannot rewrite.
Compensation
- $171k-$800k
Company info
- The Senior / Lead Site Reliability Engineer is accountable for how Stratus behaves in production.
- Reporting to the Senior Director, Platform Engineering, this role brings genuine SRE discipline to a platform that MEP contractors run their fabrication shops on - where downtime does not mean a degraded experience, it means work stops on a job site.
