The Goal

OpenBet is looking for an experienced Senior DevOps Engineer (IC3) with strong hands-on expertise across both AWS and Microsoft Azure, to help design, maintain, and evolve our cloud infrastructure.

The ideal candidate will have extensive experience with cloud networking, compute, managed data and messaging services, Kubernetes, and Infrastructure as Code (Terraform). They will play a key role in delivering complex infrastructure projects, including cross-cloud and on-premises-to-cloud migrations, ensuring secure, scalable, and highly available environments.

As a Senior DevOps Engineer, you will work independently, contribute to technical decisions, mentor other engineers, and implement changes across live, latency-sensitive systems while maintaining reliability and operational excellence.

What You’ll Be Doing

• Design, implement, and maintain cloud infrastructure across AWS and Microsoft Azure.
• Manage AWS services, including VPC, ECS or EKS, load balancers, IAM, S3, RDS or Aurora, SQS/SNS, and Kinesis or MSK.
• Work with Azure services, including Container Apps, Front Door, WAF, Functions, SQL, PostgreSQL, Event Hub, Service Bus, Entra ID, and RBAC.
• Develop, maintain, and structure reusable Terraform modules, ensuring infrastructure is managed consistently through Infrastructure as Code.
• Manage Terraform state safely and import existing manually provisioned resources into Terraform.
• Deploy, manage, and optimise Kubernetes environments across EKS or AKS, including Helm, ingress, autoscaling, and container security.
• Build, maintain, and improve CI/CD pipelines using Azure DevOps, GitHub Actions, or similar tools.
• Implement and maintain observability solutions using Datadog, Prometheus, CloudWatch, or equivalent platforms.
• Manage edge infrastructure and networking components, including Cloudflare, CDN, WAF, SSL/TLS certificates, and DNS configurations.
• Plan and execute cross-cloud and on-premises-to-cloud migrations in production environments, including staged cutovers and rollback strategies.
• Ensure the reliability, scalability, performance, and security of cloud infrastructure and services.
• Troubleshoot complex infrastructure and production issues, implementing effective and sustainable solutions.
• Work independently on technical initiatives while supporting and mentoring other team members.
• Plan and execute infrastructure changes carefully, minimising risk and disruption to live, latency-sensitive systems.

The Player

• Proven experience as a Senior DevOps Engineer, Cloud Engineer, or in a similar infrastructure-focused role.
• Deep, hands-on experience with both AWS and Microsoft Azure cloud environments.
• Strong knowledge of AWS core networking and compute services, including VPC, ECS or EKS, load balancers, IAM, and S3.
• Experience with AWS managed data and messaging services such as RDS, Aurora, SQS/SNS, and Kinesis or MSK.
• Good knowledge of Azure services, including Container Apps, Front Door, WAF, Functions, Azure SQL, PostgreSQL, Event Hub, Service Bus, Entra ID, and RBAC.
• Strong experience with Terraform, including writing reusable modules, structuring infrastructure code, managing state, and importing existing resources.
• Hands-on Kubernetes experience (EKS or AKS), including Helm, ingress controllers, autoscaling, and container security.
• Experience with CI/CD tools such as Azure DevOps, GitHub Actions, or equivalent platforms.
• Familiarity with observability and monitoring tools such as Datadog, Prometheus, and CloudWatch.
• Experience with edge and DNS technologies, including Cloudflare, CDN, WAF, SSL/TLS certificates, and DNS management.
• Proven track record of delivering production cloud migrations, including cross-cloud or on-premises-to-cloud migrations.
• Experience planning and executing staged infrastructure cutovers, with appropriate rollback and recovery plans.
• Strong troubleshooting, analytical, and problem-solving skills, with a focus on reliability and operational excellence.
• Ability to work independently, take ownership of complex technical tasks, and make sound engineering decisions.
• Experience mentoring and supporting other engineers, sharing knowledge and promoting best practices.
• Strong communication and collaboration skills, with the ability to work effectively across technical teams.
• Comfortable making careful infrastructure changes in live, business-critical, and latency-sensitive environments.
• A proactive mindset, with a strong focus on automation, continuous improvement, security, and scalability.
