Site Reliability Engineer

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).

• Build Relationships: collaborate and connect with like-minded, driven individuals in our Hudson Square office 4 days/week.
• Free lunch! Plus a pantry full of snacks.
