Full Job Description
Role Description

You'll be the senior builder on Tennr's Infrastructure team, owning the cloud, clusters, and environments that everything else runs on. This is a hands-on, high-ownership role: you'll help design our Kubernetes foundation, run dev, staging, and production end to end, and keep our AWS footprint clean, secure, and reliable as we scale.

We're looking for someone who executes fast but doesn't just take orders. The patterns you set and the guardrails you establish are the ones the rest of engineering will inherit.

Responsibilities
  • Help build out our EKS cluster module and the patterns other teams inherit from it.
  • Own cluster management and the dev, staging, and production build-out end to end.
  • Drive and unblock infrastructure migrations, keeping them safe, staged, and low-drama.
  • Lead the consolidation of our infrastructure observability onto Datadog and set the standards other teams build on.
  • Own AWS building and maintenance - networking, IAM, and core services as infrastructure-as-code. Keeping the environment secure-by-default and cost-aware.

Candidate Qualifications
  • 5-8 years in infrastructure, platform, or DevOps engineering, with real ownership of production systems.
  • Hands-on depth with Kubernetes (EKS preferred) and Terraform or comparable infrastructure-as-code.
  • Solid AWS fundamentals: networking, IAM, and the core services a modern platform runs on.
  • Experience with Datadog or a comparable observability stack, and a point of view on what good looks like.
  • Comfortable executing autonomously
  • A pragmatic bias toward simple, durable systems, and toward shipping over gold-plating
  • Bonus: experience in a regulated or healthcare (HIPAA / PHI) environment.

Why Tennr?
  • Drive Impact: one of our company values is Cowboy, meaning you set the pace. You won't just talk about things, you'll get them done. And feel the impact.
  • Develop Operational Expertise: learn the inner workings of scaling systems, tools, and infrastructure.
  • Innovate with Purpose: we're not just doing this for fun (although we do have a lot of fun). At Tennr, you'll join a high-caliber team maniacally focused on reducing patient delays across the U.S. healthcare system.
  • 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.

Benefits
  • Beautiful new office at 345 Hudson Street
  • Unlimited PTO
  • 100% paid employee health benefit options
  • Employer-funded 401(k) match
  • Competitive parental leave
