Job Purpose
We are looking for a Senior Platform Engineer with strong DevOps experience, combining deep operational expertise with a development background. You are comfortable working at the intersection of infrastructure, security, and application development, and you enjoy enabling other teams to move faster through well-designed platforms and abstractions. You bring both a builder and operator mindset: you design scalable systems, automate everything possible, and take ownership of platform reliability in production.
Key Responsibilities
- Build and maintain core platform components (SSO, Access Management, clusters, networking, CI/CD, observability).
- Own Terraform modules, baseline configurations, and guardrails for distributed teams.
- Design and evolve platform “golden paths” — secure defaults, templates, and standards.
- Maintain platform IaC (Terraform, modules, state design, multi-account governance).
- Integrate with team-owned CDK stacks through stable platform contracts.
- Lead evolution of platform abstraction layers and service catalogs.
- Design and manage multi-account AWS landing zone (Orgs, SCPs, permissions boundaries).
- Own developer onboarding patterns (IAM SSO access, automation, pipelines).
- Build safe cross-account deployment workflows (GitHub OIDC, least privilege).
- Design and operate ECS and EKS clusters used by hundreds of services.
- Establish best practices for container execution, networking, autoscaling.
- Manage central networking components (VPC, TGW, Route53).
- Ensure secure east–west communication between workloads in different accounts.
- Provide self-service tools and templates for teams (pipelines, service definitions, actions).
- Abstract platform complexity to enable fast and safe deployments for all teams.
- Own documentation, workshops, patterns, and architectural guidance.
- Operate and evolve platform-wide logging, metrics, and tracing systems.
- Ensure operational standards for platform components.
You are meant for this job if:
- Strong experience as a Platform Engineer / DevOps Engineer operating production systems at scale
- Proven +4 years hands-on expertise with AWS, especially multi-account environments and organizational governance
- Deep understanding of Infrastructure as Code, particularly Terraform (modules, state management, guardrails)
- Solid experience running and operating EKS and/or ECS in production
- Strong background in CI/CD, GitHub-based workflows, and secure deployment patterns (OIDC, least privilege)
- Experience designing developer platforms and internal tooling for self-service and standardization
- Strong understanding of cloud security, IAM, SCPs, permissions boundaries, and secure networking
- Operational excellence mindset: monitoring, logging, alerting, SLOs, and incident handling
In addition to infrastructure and operations, you have hands‑on development experience, allowing you to collaborate closely with application teams and design pragmatic platform contracts:
Professional experience developing services in one or more of:
- Java / Kotlin (Spring Boot)
- Node.js / TypeScript
Familiarity with modern API design, service runtime concerns, and container-based workloads
Ability to read, debug, and contribute to application code when needed
