Principal DevOps Engineer — Platform Infrastructure (AWS) (Poland)

The role

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

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
