What you’ll do
As a Senior Platform Engineer, you will focus on improving Developer Experience and building self-service automation around Infrastructure as Code. This includes designing, building, and evolving “Golden Paths” for IaC that enable our engineers to build, test, and manage infrastructure and/or applications at scale across multi-cloud environments.
Your goal is to build self-service abstractions around Terraform and Terragrunt ecosystems that reduce cognitive load and allow developers to provision compliant, secure, and cost-effective infrastructure without needing to be cloud experts.
You will own the end-to-end lifecycle of our infrastructure and related application delivery tooling—shaping standards, improving developer/engineer experience, and embedding security, compliance, and observability into every stage of the pipeline. Working closely with application teams, SRE, security, and cloud platform engineers, you will act as both a technical leader and a force multiplier for engineering productivity. You are not just building infra; you are building the product that other engineers use to ship their code.
In this role, you will balance hands-on engineering with platform strategy, ensuring our CI/CD systems are resilient, cloud-agnostic, and optimized for scale as our environments and teams grow.
What you’ll bring
IaC Mastery: Expert-level experience with Terraform and Terragrunt for managing complex, multi-account cloud environments (AWS, GCP, or Azure).
Scaling IaC: Deep understanding of state management at scale, modular design patterns, and CI/CD for Infrastructure (e.g., Atlantis, Spacelift, or custom GitLab/GitHub actions).
Golden Path Architecture: Proven track record of designing platform abstractions and self-service developer tooling that hide cloud complexity from application teams.
Automated Infrastructure Testing: Deep experience with Terratest (Go-based) to write unit and integration tests for IaC modules. You should be able to programmatically provision, validate, and teardown resources to ensure module contract stability.
Policy as Code (PaC): Experience embedding governance into the workflow using tools like OPA (Open Policy Agent), or Checkov to bake in security and compliance.
Strong hands-on experience building and operating CI/CD platforms at scale
Expertise with Kubernetes in multi-cloud environments (AWS, GCP & Azure)
Proven experience with modern CI/CD, GitOps, and deployment platforms (e.g. GitLab CI) for infrastructure management
Strong automation skills using Go, Python and shell scripting
Experience optimizing tooling/pipeline performance, reliability, and cost
Developer Empathy: A product-mindset approach to infrastructure—treating internal developers as customers and focusing on "Builder Experience."
Clear technical communication with engineers and stakeholders
Ability to collaborate and influence across teams without formal authority
High sense of ownership and accountability for platform outcomes
Pragmatic problem-solving and sound engineering judgment
Bias for automation, simplification, and continuous improvement
Willingness to mentor and share knowledge
