Job summary

Commit is seeking a Principal DevOps Engineer to design and build the AWS infrastructure and delivery platform for a new gaming platform. The role is hands-on, setting cloud foundations, account structure, networking, Kubernetes platform, CI/CD, and observability.

You will enable scale to sportsbook peak traffic with uptime guarantees and regulatory compliance, mentoring teams while shaping standards for how software runs in production.

Qualifications

• 10+ years in DevOps/platform/infrastructure engineering.
• 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.
• Expert-level infrastructure as code with Terraform.
• Strong Kubernetes day-2 operations and cost management.
• Track record building CI/CD and developer platforms teams.
• Observability and SLO/error-budget practice (Prometheus/Grafana, OpenTelemetry, CloudWatch).
• Experience operating high-availability, high-throughput production systems with real traffic spikes.
• Excellent written and spoken English; communicates platform decisions clearly to engineers and executives.

Responsibilities

• Design the AWS foundation from scratch for multi-account architecture.
• Build and operate the container platform with EKS and service mesh.
• Define everything as code using Terraform and GitOps pipelines.
• Establish observability stack with metrics/logging/tracing.
• Own production readiness including incident response and runbooks.
• Migrate from current third-party platform with dual-running environments.
• Embed compliance and regulator audit controls by construction.
• Partner with AI coding platform team to integrate AI tooling.
• Mentor engineers and set org-wide cloud standards.

Job 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
