Senior DevOps Engineer (AWS)

Duetto Research

Responsibilities

  • Design and implement robust, scalable AWS infrastructure — supporting key system migrations, platform growth, and the reliability our customers depend on.
  • Own the reliability, performance, and security of our production environment: high uptime, rapid incident resolution, and proactive capacity planning.
  • Build and maintain CI/CD pipelines, deployment automation, and infrastructure-as-code using Terraform, Terragrunt, and Chef.
  • Monitor system health using enterprise observability tools (Prometheus, Grafana, DataDog), defining metrics and response playbooks that get ahead of incidents before they happen.
  • Lead security-first practices across the infrastructure estate — proactively addressing vulnerabilities and driving SOC 2 compliance.
  • Partner with engineering teams to integrate operational requirements into the development lifecycle and align on architecture decisions.
  • Champion AI adoption within DevOps and SRE workflows, evaluating tooling that increases team velocity and reduces toil.
  • Respond to on-call incidents with urgency — troubleshoot complex issues, lead detailed root cause analyses, and implement fixes that prevent recurrence.

Requirements

  • 5+ years in a DevOps, SRE, or infrastructure engineering role.
  • Strong working knowledge of enterprise monitoring platforms — Prometheus, Grafana, or DataDog.
  • Solid troubleshooting skills and a track record of leading root cause analyses and implementing durable fixes.
  • Proficiency reading Java, Ruby, Bash/Zsh, HCL, Python, and JavaScript.

What we’re looking for

You may be a great fit if you have

  • Hands-on AWS experience across IAM, VPC, EC2, ELB, RDS, S3, Lambda, API Gateway, Secrets Manager, KMS, CloudWatch, and CloudTrail — including multi-account management and SSO.
  • Proficiency with Terraform for infrastructure-as-code, plus experience with configuration management tools like Chef or Ansible.
  • Experience with CI/CD tooling including GitHub, GitHub Actions, JFrog Artifactory, and Jenkins, with familiarity with GitOps methodologies.
  • Experience with container and orchestration technologies — Docker, ECS, or EKS.
  • Experience with SOC 2 compliance and security-first infrastructure practices.
  • Comfort with a weekly on-call rotation.

Strong candidates may also have

  • Experience migrating workloads from on-prem or colocation environments to AWS.
  • Familiarity with Windows Server, SQL Server, IIS, and .NET environments.
  • Experience administering and synchronising MongoDB replica sets.
  • Knowledge of ISO 27001, Layer 7 load balancing, or Terragrunt.
  • Background in hospitality technology.
  • A degree in Computer Science or a related field — or equivalent experience.
