INFUSE is looking for a Senior DevOps Engineer to own and evolve our AWS infrastructure, CI/CD pipelines, and observability stack. You will bridge cloud engineering and software development across our entire product suite, including production LLM products and legacy systems requiring modernization.

We need a proactive technical partner to lead our transition to EKS and GitHub Actions, enforce zero-trust security baselines, and mentor engineering teams along the way.

As part of our dynamic team, your responsibilities in this role will include:

• Design, build and run secure AWS infrastructure (EC2 with Docker Compose, EKS) with Terraform and Ansible; move suitable workloads from EC2 to EKS
• Build and maintain CI/CD in GitHub Actions; move remaining Jenkins jobs to GitHub Actions
• Keep new and existing services at our security baseline: Cloudflare proxy with WAF and rate limiting, origins open only to Cloudflare, SSM access, no public SSH, least-privilege IAM, secrets rotation, regular patching and rebuilds, no containers running as root
• Own monitoring, alerting and logs on our standard stack (Grafana, OpenTelemetry, Sentry); on-call, incident response, post-incident reviews
• Own backups and regular restore tests
• Control AWS cost: tags, rightsizing, removing unused resources, estimates for new projects
• Regularly review the infrastructure we run, find risks and waste, and come with a plan without waiting for a ticket
• Take over infrastructure that is undocumented or run by contractors; document it and bring it under IaC, CI/CD and our standards
• Join new projects at kickoff: review hosting design, estimate cost, prepare infrastructure for the production-readiness review
• Work with internal teams and contractors; set and enforce standards; mentor other engineers.
