Senior DevOps Engineer – Cloud Platform

Role Overview

We are looking for a Senior DevOps Engineer to help design, standardize, and operate the cloud platform behind our multi-tenant SaaS product on AWS.

In this role, you will work at the intersection of platform engineering, automation, and developer enablement. Your primary responsibility is to build and maintain a secure, scalable, and highly automated Kubernetes-based platform, allowing development teams to ship software reliably and efficiently.

You will treat the platform as an internal product, with developers as your main stakeholders, and will play a key role in defining standards, best practices, and long-term architectural decisions.

Key Responsibilities

• Design, evolve, and operate a cloud-native platform running on AWS and Kubernetes.
• Define and maintain platform standards for infrastructure, security, networking, and deployments.
• Drive automation-first practices across infrastructure provisioning, deployments, and operations.
• Enable development teams by providing reliable tooling, CI/CD pipelines, and self-service capabilities.
• Embed DevSecOps principles into the platform by default.
• Apply FinOps practices to improve cost visibility, efficiency, and accountability.

Requirements

Essential

• Strong, hands-on experience running Kubernetes in production environments.

• Experience building and maintaining CI/CD pipelines using GitHub Actions and/or Azure DevOps.
• Solid understanding of security best practices: IAM, least privilege, secrets management, container security.
• Strong automation mindset, including scripting (Bash, Python, or Go).
• Relevant certifications such as CKA and/or AWS certifications.
• Advanced, day-to-day use of Git in collaborative environments.
• Experience operating highly available and resilient systems, including disaster recovery (RPO/RTO) planning.

Desirable

• Deep, real-world experience with the Kubernetes ecosystem (ArgoCD, backups, service mesh, observability).
• Ability to design and maintain reusable IaC modules and platform abstractions.
• Real experience implementing DevSecOps and security-by-design approaches.
• Hands-on experience with FinOps tooling and cost optimization strategies.
• Ability to design and operate progressive delivery strategies (blue/green, canary deployments).
• Comfortable collaborating across Product, Development, QA, and Architecture teams.
• Clear communication skills and ability to document standards, patterns, and best practices.
