Site Reliability Engineer
Confirmed on the employer's own hiring board on Nov 4, 2026. First seen by Alion on Sep 13, 2026. Tennr scores A on the Alion truth index.
Company Description
Today, when you go to your doctor and get referred to a specialist, your doctor sends out a referral and tells you, “They’ll be in touch soon.” So you wait. And wait. Sometimes days, weeks, or even months. Why? Because too often providers are overwhelmed with the painstakingly tedious work required to get paid by insurance companies. Powered by proprietary models, Tennr handles the complex paperwork that gets patients through the door and providers paid, helping operators get patients the right care, at the right time, in the right setting.
Role Description
You’ll join Tennr’s Infrastructure team as a Site Reliability Engineer, focused on the systems that keep us reliable, observable, and secure. This is a hands-on role with real room to grow: you’ll roll out our on-call tooling, wire observability into the product, and own the lifecycle of the credentials, certificates, and keys that protect patient data.
It’s a great fit for someone a few years into their career who wants to grow into deep SRE ownership - with strong mentorship, real problems to solve from day one, and a direct line to the reliability and security of a platform that handles PHI.
Responsibilities
Continue the PagerDuty rollout across engineering teams, helping them define escalation policies, schedules, and runbooks so on-call is calm and clear.
Build in-app Datadog instrumentation - metrics, traces, and alerts - working from the observability standards Infrastructure sets.
Manage credential storage and rotation across our environments.
Manage certificate issuance, renewal, and rotation.
Manage encryption key lifecycle and rotation, keeping PHI protected end to end.
Candidate Qualifications
2-4 years in SRE, infrastructure, systems, or a strong adjacent engineering background.
Familiarity with PagerDuty or a comparable on-call and incident-response tool.
Hands-on with Datadog or another observability platform, or eager to go deep on it.
Working understanding of secrets, certificate, and key management (e.g. AWS Secrets Manager / KMS / ACM, HashiCorp Vault).
Careful and methodical with anything touching security and rotation - you sweat the details.
Eager to grow into broader SRE ownership, and energized by working in a regulated healthcare (HIPAA / PHI) environment.
