About The Position

Our client is a remote-first digital product company building and scaling SaaS products, AI-powered solutions, and web and mobile applications for global markets. The company operates across more than 20 countries and brings together distributed engineering, product, design, data, and growth teams. Its engineering organization includes approximately 40–50 engineers working across multiple product teams and supporting a portfolio of around 15 digital products. Our client is looking for a Head of Platform Engineering to take full ownership of the company’s infrastructure and platform function. You will lead an established team of four engineers — three DevOps Engineers and one SRE — and work closely with the CTO and Engineering Leads across the organization. The infrastructure function is currently overseen by an interim, part-time Head of Infrastructure. The new Head of Platform Engineering will become the permanent owner of the function, define its long-term direction, and lead its next stage of development. The role sits at the intersection of infrastructure reliability, developer experience, security, automation, and engineering efficiency. You will inherit an existing cloud environment supporting approximately 15 products and multiple engineering teams. Your responsibility will be to introduce greater consistency, visibility, scalability, and operational maturity across the platform. This is a technically strong leadership role. You will not be expected to personally handle routine operational work, but you should remain close enough to the technology to guide architecture, review critical decisions, challenge assumptions, and support the team with complex infrastructure and production issues when needed.

Requirements

7+ years of experience in Platform Engineering, DevOps, Site Reliability Engineering, Cloud Infrastructure, or a related field.
2+ years leading a Platform, Infrastructure, DevOps, or SRE function.
