About the role

You will design and build a scalable, resilient AWS infrastructure and delivery platform from scratch to support high-traffic gaming systems. You will also act as a hands-on technical leader, defining infrastructure as code, establishing observability practices, and mentoring engineering teams.

What they look for

AWS Kubernetes Terraform CI/CD Observability Python Go Bash EKS Infrastructure as Code GitOps System Architecture Cloud Security Disaster Recovery Technical Leadership Reliability Engineering

Requirements

The role requires over 10 years of experience in DevOps or infrastructure engineering, with deep expertise in AWS, Kubernetes, and Terraform. Candidates must have a proven track record of operating high-availability production systems and strong communication skills in English.

Full description

We are looking for Principal DevOps Engineer to design and build the AWS infrastructure and delivery platform the new gaming platform will run on. Greenfield: define the cloud foundation — account structure, networking, Kubernetes platform, CI/CD, observability — before the first production workload lands, then scale it to sportsbook peak traffic for millions of players. The platform must hold under live-betting spikes, strict uptime expectations for a money-moving system, and gaming-regulator audit and compliance requirements. Hands-on technical leader: writes infrastructure code daily, sets platform standards, and is the technical authority on how software is built, shipped and operated.

What you will do:

  • Design the AWS foundation from scratch: multi-account architecture (AWS Organizations), landing zone, VPC and networking, IAM strategy, cost governance
  • Build and operate the container platform — Amazon EKS, service mesh, autoscaling tuned for spiky sportsbook load, multi-AZ (and where justified multi-region) resilience
  • Define everything as code: Terraform for all infrastructure, GitOps delivery (Argo CD or similar), paved-road CI/CD pipelines so product teams ship safely and often
  • Establish the observability stack — metrics, logging, tracing, alerting (Prometheus/Grafana, OpenTelemetry, CloudWatch) — and drive an SLO-based reliability practice with error budgets
  • Own production readiness: incident response, on-call design, runbooks, chaos/load testing ahead of major sporting events, blameless postmortems
  • Build the infrastructure side of the migration off the current third-party platform: dual-running environments, data migration pipelines, cutover mechanics
  • Embed compliance into the platform: audit trails, environment segregation, backup/DR, controls that satisfy gaming regulators by construction
  • Partner with the AI coding platform team: provision and operate the infrastructure behind AI-assisted development, and bring AI tooling into DevOps workflows
  • Mentor engineers across teams on cloud-native and operational best practices; set organization-wide standards

Requirements

Must have:

  • 10+ years of DevOps / platform / infrastructure engineering, including 3+ years at staff/principal level with organization-wide influence
  • Deep hands-on AWS: EKS, EC2, RDS/Aurora, networking (VPC, Transit Gateway, Route 53), IAM at scale, multi-account architectures (AWS certifications such as SA Professional / DevOps Professional are a plus)
  • Expert-level infrastructure as code with Terraform
  • Strong Kubernetes operational depth: day-2 operations, upgrades, capacity, cost
  • Track record of building CI/CD and developer platforms engineering teams adopted willingly — golden paths, not gatekeeping
  • Observability and SLO/error-budget practice (Prometheus/Grafana, OpenTelemetry, CloudWatch)
  • Experience operating high-availability, high-throughput production systems with real traffic spikes, with documented playbooks from real incidents
  • Strong scripting/programming (Python, Go or Bash) and comfort reading application code
  • Experience designing backup, disaster recovery and business continuity for systems where data loss is not an option
  • Excellent written and spoken English; communicates platform decisions clearly to engineers and executives

Nice to have:

  • Hands-on use of AI coding tools (Claude Code, Codex) for infrastructure, pipelines and ops automation — a significant plus
  • Security engineering: cloud security posture management, secrets management (e.g. Vault), vulnerability management, SAST/DAST/SCA in CI/CD, ISO 27001 / SOC 2 / PCI DSS
  • iGaming, sports betting, fintech or another regulated, high-transaction-volume domain
  • Migration off a third-party vendor platform
  • Event-streaming infrastructure (Kafka/MSK) and database operations at scale
  • Polish and/or Spanish
