The posting

As a Site Reliability Engineer (SRE) at Fountain, you’ll own the reliability, scalability, and operational excellence of the systems that power our platform. You’ll partner closely with Engineering, Security, and Product to build resilient infrastructure, improve developer experience, and raise the bar on observability and incident response.

What you'll be doing:

  • Own and improve platform reliability (SLOs/SLIs), capacity planning, and production readiness
  • Design, build, and maintain Kubernetes-based infrastructure and deployment workflows
  • Operate and evolve our AWS footprint (networking, compute, storage, IAM) with a security-first mindset
  • Improve our CD/GitOps practices (ArgoCD) and deployment safety (progressive delivery, rollbacks, guardrails)
  • Build autoscaling strategies for services and workloads (KEDA where appropriate)
  • Lead incident response: on-call, triage, mitigation, postmortems, and preventative follow-through
  • Strengthen observability across services: metrics, logs, traces, and alerting (OpenTelemetry + dashboards)
  • Partner with application teams to tune performance, reduce toil, and improve operational maturity
  • Improve infrastructure-as-code practices and maintain Terraform modules and environments
  • Contribute to evaluating and integrating AI tooling and MCP tools to accelerate operational workflows

What you should bring:

  • 5+ years of experience in site reliability engineering
  • Experience owning reliability for production systems — defining SLOs or running error budgets
  • Deep hands-on experience with Kubernetes/Helm on EKS in production
  • Experience with Cloudflare (CDN, WAF, etc)
  • Experience with CI/CD or general GitOps deployment pattern experience
  • Has led or significantly contributed to incident response and postmortem processes
  • Working knowledge of AWS core services (networking, IAM, compute) beyond just EKS

Nice to have:

  • Experience evaluating or building AI-assisted ops tooling (MCP, agentic runbooks)
  • OpenTelemetry / observability pipeline design
  • ArgoCD, KEDA autoscaling
  • Experience with Terraform

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
