Description
ABOUT PLENFUL
Plenful is on a mission to transform healthcare operations from the inside out. Fresh off our $50M Series B and backed by Notable Capital, Bessemer Venture Partners, TQ Ventures, Susa/Kivu Ventures, and other leading investors, we’re building the category-defining AI workflow automation platform that healthcare teams rely on to operate smarter, faster, and more efficiently. Our technology empowers healthcare operators across hospital and health systems, pharmacies and payors to eliminate manual work, reduce administrative burden, and improve compliance, all while unlocking critical revenue to fund programs for their in-need patient populations.
Built by healthcare operators for healthcare operators, Plenful is driven by a deep understanding of the challenges facing today’s care teams. We’re passionate about equipping healthcare workers with world-class tools that deliver real, measurable impact, and we’re proud to serve 90+ leading health systems across the country. If you’re excited to help shape the future of healthcare, we’d love to meet you. Apply now to join our growing team.
ABOUT THE ROLE
Plenful is hiring a Senior Site Reliability Engineer (SRE) to keep our production systems reliable, performant, and scalable as we grow.
This role is centered on operating real systems at scale — not just building infrastructure, but understanding deeply how it behaves under load, fails in production, and recovers. You'll define reliability standards, own production health, and build the feedback loops that make our systems more resilient over time.
You'll work closely with backend, data, and ML engineers to keep the platform highly available, measurable, and continuously improving — from incident response and performance debugging to SLO design and system-level optimization. This role is hybrid.
WHAT YOU’LL DO
Reliability Engineering & System Ownership
- Define and implement SLIs, SLOs, and error budgets across core services.
- Own production system health: uptime, latency, and availability targets.
- Improve system resilience through proactive reliability work.
- Find and mitigate single points of failure across distributed systems.
Production Operations & Incident Response
- Take part in and improve on-call rotations and incident response.
- Lead incident triage, mitigation, and resolution in real time.
- Run blameless postmortems and follow through on action items.
- Build tooling and automation to cut MTTR (Mean Time to Recovery).
Observability & System Insight
- Design and evolve observability across metrics, logs, and distributed tracing (OpenTelemetry), using tools like Datadog, CloudWatch, Grafana, and Sentry.
- Improve signal quality to cut noise and alert fatigue.
- Build dashboards and alerts that reflect real system health and user impact.
- Use observability data to drive performance and reliability improvements.
Performance & Scalability
- Analyze system performance under load and find bottlenecks.
- Optimize latency, throughput, and resource use across serverless (AWS Lambda), containerized services (ECS), and data systems (Aurora Postgres, ClickHouse).
- Partner with engineering teams to improve system efficiency and scaling behavior.
Automation & Reliability Tooling
- Build automation that eliminates repetitive operational work.
- Improve deployment safety through reliability checks and safeguards.
- Contribute to CI/CD pipelines (GitHub Actions) with a focus on stability.
- Build tools for incident response, debugging, and capacity planning.
Security, Compliance & Operational Maturity
- Partner with security and compliance to keep systems meeting operational standards.
- Support audit readiness and reliability-related compliance requirements (Vanta).
- Integrate monitoring and alerting into security and SIEM workflows.
- Help mature operational practices across engineering.
