Senior Platform Engineer

About the role

Senior Platform Engineer

Who we are

Join the fintech revolution with Mambu, the leading SaaS cloud banking platform. We're on a mission to make banking better for a billion people. Explore exciting career opportunities and help shape the future of financial services.

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
