Senior Site Reliability Engineer (Systems Engineer III)

Ophelia provides telehealth treatment for opioid use disorder. The Senior Site Reliability Engineer will own the reliability, availability, performance, and disaster recovery of its GCP platform, while building observability and incident response practices and strengthening infrastructure automation and security controls.

Responsibilities:

• Own reliability, availability, and performance of our GCP platform. Define and operationalize SLOs and service level indicators (SLIs) with the team, and drive the work that moves them (e.g., endpoint latency, Cloud Run cold starts, time to recovery), and own our disaster recovery posture (e.g., Firestore backup and restore testing, recovery point and recovery time objectives, and multi-region resilience)
• Build observability and incident response. Extend our GCP Cloud Operations setup (log-based metrics, alerting policies, dashboards), move alerting from Slack into PagerDuty, participate in our on-call rotation alongside the rest of the team, and mature that process with clear incident categorization, escalation paths, and an AI-assisted level-one triage tool
• Grow our infrastructure as code and delivery pipeline. Expand our Terraform footprint beyond observability metrics and ephemeral pull request (PR) environments to the rest of our GCP configuration, and improve our GitHub Actions CI/CD pipeline so that deploying four times a day gets safer and faster, not riskier
• Harden security and compliance controls in partnership with our head of IT, who is the DRI for IT security and our HIPAA/SOC 2 infrastructure controls
• Multiply the team. Level up our engineers' GCP and DevOps skills through presentations, docs, runbooks, pairing, and code review; bring reliability recommendations to new features early; share reusable AI skills and automation across the team; and set the bar for operational excellence by embodying Ophelia's core values
• Take ownership of your work in our remote, growth-stage environment, driving projects from inception to impact with autonomy and proactive communication, adapting as our priorities evolve, and staying current with industry practice (including AI tooling) in reliability and cloud infrastructure

Requirements:

• 5+ years experience in engineering, including 3+ in a cloud infrastructure, DevOps, or SRE-focused role
• Expert-level, hands-on GCP fluency, including serverless compute (e.g., Cloud Run), Cloud Operations (Logging, Monitoring, alerting), IAM, and Firebase/Firestore
• Expert in at least one language used for infrastructure automation (e.g., Python) and strong in shell scripting
• You should be comfortable reading and debugging TypeScript/Node, as that's our entire application codebase
• Production operations experience, including participating in on-call, leading incident response, writing postmortems, and defining SLOs in keeping with Google SRE practice, and the judgment to adapt those practices to a small team's capacity rather than importing large-company process wholesale
• Quantitative fluency applied to production systems, e.g., percentiles and tail latency rather than averages, SLO and error-budget math, burn-rate alerting, and reading time series and histograms well enough to tell signal from noise
• Senior-level ownership and communication, with the ability to own complex, ambiguous projects end-to-end with technical and non-technical stakeholders, clear and proactive communication, and a habit of writing things down (runbooks, postmortems, design docs) and pairing so that knowledge doesn't live only with you
• Daily, hands-on use of AI tools in your own engineering work (e.g., Claude Code for Terraform, runbooks, and log analysis), and experience building automation with them rather than only using them
• Terraform fluency is strongly preferred
• SQL for BigQuery and Log Analytics is a plus
• Passionate about our mission to make evidence-based addiction treatment universally accessible
• Background in a regulated industry, ideally healthcare - telehealth is a big plus - with hands-on experience implementing HIPAA or SOC 2 infrastructure controls
