Senior Platform Engineer - Financial Cloud

Requirements:

• 6+ years of experience in backend, platform, infrastructure, or developer tools engineering
• Strong proficiency in Go (preferred primary language) or Java/Kotlin, plus Python scripting
• Production experience developing CI/CD pipelines with GitHub Actions, Tekton, Jenkins, or custom pipeline orchestrators
• Hands-on experience with GitOps tools such as ArgoCD, Flux, and Kustomize at scale across 10+ clusters or environments
• Kubernetes experience, including operators, custom controllers, CRDs, and Helm chart development
• Understanding of container registries and artifact management, such as Harbor, ECR, or Artifactory
• Experience with build systems such as Bazel or Gradle, including reproducible builds, remote caching, and build graph optimization
• Background in dependency analysis tooling or graph databases such as Neo4j, Dgraph, or custom implementations
• Preferred: Experience with AWS tools such as CodePipeline, CodeBuild, Proton, or Service Catalog, or GCP tools such as Cloud Build, Artifact Registry, or Cloud Deploy
• Preferred: Experience on developer platform teams at Stripe, Adyen, or Square
• Preferred: Experience building internal developer platforms or platform-as-a-service offerings for engineering organizations
• Preferred: Familiarity with supply chain security tools such as Sigstore, in-toto, or SBOM generation

Responsibilities:

• Build module-level CI/CD pipelines that publish versioned Docker images and Kubernetes manifests, enforcing reproducible builds through hermetic environments, pinned toolchains, and deterministic outputs
• Automate build provenance, including SLSA attestations, artifact signing, dependency-chain verification, and CI validation of required Golden Signals metrics endpoints
• Develop a dependency graph database that combines static and runtime dependencies and supports impact-analysis queries
• Create change-impact tools that identify affected modules, sites, and tests from a pull request, surface findings in the review interface, and run only relevant tests based on the dependency graph
• Implement a GitOps deployment engine using ArgoCD or Flux to reconcile site configuration and promote releases from staging through canary to production, with monitoring and automatic rollback
• Build site-provisioning tools that generate configuration repositories with pinned module versions and compliance parameters, along with a self-service console for configuration-type sites
• Develop a version-management console for tracking module status and version drift, coordinating batch upgrades, generating changelogs, and checking compatibility before deployment
• Implement a security patch pipeline that automatically creates required security pull requests across site repositories and tracks service-level agreements and escalations
• Build a four-layer test orchestrator that selects tests by module, country, and scenario tags; runs them in parallel at scale; and detects coverage gaps to block deployments with actionable feedback
