Senior DevOps Engineer

Duetto is a leading revenue management platform for the hospitality industry, committed to providing technology that enhances revenue strategies for hotels, resorts, and casinos. As a Senior DevOps Engineer, you will design and implement scalable AWS infrastructure, ensure the reliability and security of production environments, and promote AI adoption within DevOps workflows.

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
• 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
• 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
• Experience with SOC 2 compliance and security-first infrastructure practices
• Comfort with a weekly on-call rotation
• Experience with container and orchestration technologies — Docker, ECS, or EKS
• 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
