Senior Infrastructure Engineer

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 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.
