Principal Platform Engineer
Location: Belfast – Hybrid (2 days onsite)
Salary: Up to £90,000 + Bonus & Benefits
Type: Permanent | Exclusive Opportunity
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-native 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 languages.
* Deep understanding of CI/CD practices and Infrastructure as Code (Terraform preferred).
* 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.
