Position: Senior DevOps Engineer I
Location: St. Louis

Geneoscopy is building next‑generation diagnostic software, and our Dev Ops team is at the heart of making it reliable, scalable, and secure. As a Senior Dev Ops Engineer, you will take ownership of our cloud‑native infrastructure and delivery pipelines, enabling engineering teams to ship fast and safely. You'll work hands‑on across the stack from infrastructure and Kubernetes to CI/CD and Git Ops, while helping shape Dev Ops best practices as we scale.

This role is ideal for someone who thrives in a startup environment, enjoys solving complex problems, and wants to have a direct impact on product delivery and system reliability.

NOTE: This is a contract‑to‑hire opportunity, beginning with hourly compensation during the contract period and transitioning to a salaried role upon conversion.

RESPONSIBILITIES
  • Design, build, and operate cloud infrastructure using Infrastructure as Code to rapidly spin up and manage environments (dev, test, staging, production).
  • Own and evolve our Kubernetes platform (AWS EKS) with a focus on reliability, scalability, and cost efficiency.
  • Use Helm to package, version, and deploy Kubernetes applications consistently.
  • Implement and manage Karpenter for dynamic cluster autoscaling and efficient node provisioning.
  • Build and maintain Docker‑based container images, optimizing for security, performance, and reproducibility.
  • Manage container image storage and promotion using Amazon ECR.
  • Drive Git Ops workflows with FluxCD or equivalent to automate deployments and maintain environment parity.
  • Define and enforce Git workflows and branching strategies that support fast iteration without sacrificing stability.
  • Build and maintain Git Lab CI/CD pipelines for continuous integration, testing, and delivery.
  • Create automated deployment pipelines that support seamless promotion across environments.
  • Partner closely with software engineers to remove friction from the development process and improve developer experience.
  • Anticipate scaling and reliability needs by reviewing application architecture and usage patterns early.
  • Troubleshoot infrastructure and application issues, jumping in where needed to unblock teams.
  • Improve security, observability, monitoring, backups, and disaster recovery as the platform grows.
  • Collaborate cross‑functionally with engineering, laboratory, and IT teams to continuously improve systems and processes.
  • Take ownership of complex problems, make pragmatic decisions, and help set the technical direction of Dev Ops at Geneoscopy.
  • Exemplify expert knowledge of the subject matter.
  • Provide coaching and/or mentoring to other engineers as the team scales.
  • Other duties as assigned.
