The Role
The Tech Platform organization maintains and evolves the foundational platform and shared services that every other DT workstream depends on. As we assemble siloed products into a single marketplace, getting the platform right - reliable, observable, standardized, and cost-efficient - is the critical variable for execution at marketplace scale.
As a Senior Infrastructure Engineer, you'll design and operate the large-scale distributed systems, data infrastructure, and deployment platforms that serve tens of billions of daily events. You'll help drive our OneDT standardization - including the migration to GitOps/ArgoCD and unified CI/CD - and build the platform capabilities (including ML and data infrastructure) that the rest of engineering builds on.
About the Senior Infrastructure Engineer Role
Design, build, and operate large-scale distributed systems and data platforms for reliability, scalability, and cost-efficiency
Drive the OneDT platform standardization: GitOps/ArgoCD adoption, unified CI/CD pipelines, and a clear developer-ownership model across business lines
Build and operate Kubernetes-based infrastructure, including Spark-on-K8s and data/ML platform tooling (e.g., Databricks ecosystems)
Implement MLOps and data-pipeline capabilities - training, deployment, and serving infrastructure - in partnership with ML and Data teams
Champion observability, automation, and cost-optimization initiatives that improve reliability while reducing spend
Participate in on-call rotations, lead incident response and blameless postmortems, and prevent recurrence through automation and platform improvements
About You as the Senior Infrastructure Engineer

Deep experience with a major cloud provider (AWS or GCP; Azure a plus) and proficiency in Go, Java, Python, or Scala
Strong hands-on experience building and operating Kubernetes infrastructure stacks.
Familiarity with data and/or ML infrastructure: Spark, Kafka, data lakes, Databricks, or comparable technologies

Operational maturity: you've owned production systems, run on-call, and improved reliability systematically
Nice to have
Experience leading large migrations or platform-standardization programs across multiple teams
Background in high-throughput, low-latency systems such as real-time bidding or event streaming
Experience with cost governance (FinOps) at scale
