We’re hiring exclusively for a scaling tech company with a clear mission : to empower engineers by investing heavily in Developer Experience (DevEx) . They’re now seeking a Principal Platform Engineer to lead that mission — designing the tools, environments, and infrastructure that make engineering smoother, faster, and more reliable across the entire organisation.

This is a standout role for an engineer who understands that great platforms don’t just run code — they elevate the people writing it. If you're passionate about internal tooling, streamlined workflows, and removing friction for developers, this is your chance to make DevEx a first-class product.

The Impact You’ll Make

  • Lead DevEx strategy and vision, improving usability, velocity, and autonomy for engineers.
  • Build internal tools using Go and TypeScript to streamline infrastructure, automation, and CI / CD.
  • Architect scalable, cloud- systems across AWS, Kubernetes, and Infrastructure as Code (Terraform / CDK).
  • Drive improvements to CI / CD pipelines and deployment processes to enable faster, safer delivery.
  • Collaborate cross-functionally and mentor engineers while shaping platform and engineering culture.
  • Improve system reliability, observability, and incident response through proactive platform design.
  • Continuously identify and eliminate inefficiencies in the developer workflow.

What You Bring

  • 8+ years of experience in software engineering, ideally with recent platform or DevEx leadership.
  • Strong experience with Go, TypeScript, or similar .
  • Deep understanding of CI / CD practices and Infrastructure as Code (Terraform ).
  • Hands-on expertise with AWS and Kubernetes in production environments.
  • A user-centric mindset focused on delivering excellent internal developer experiences.
  • Clear communication and a passion for mentoring and technical leadership.
  • Proven ability to balance technical trade-offs and influence platform direction.

    • Bonus Points

  • Experience with developer portals such as Backstage.
  • Familiarity with event-driven systems and event catalogue tooling.
  • Contributions to open-source projects, especially within the CNCF ecosystem.
  • Relevant certifications in AWS and / or Kubernetes.

    • This is a career-defining opportunity for a senior engineer who wants to lead DevEx at scale, creating a fast, intuitive, and reliable developer environment that drives impact across the business.
