About ENSEK

ENSEK builds the cloud‑native SaaS software that’s transforming how energy retailers operate, innovate and manage at scale.

We help retailers lower operating costs, improve billing accuracy for consumers, and enhance customer experience through automation and AI‑driven insight, all underpinned by modern, cloud‑native architecture.

ENSEK is at an exciting inflection point as we scale at pace towards new international horizons. If you’re driven by solving complex, real‑world problems and want to build modern technology that accelerates the global energy transition, you’ll feel right at home with us.

About the role

The Platform Engineer III is an experienced engineer who delivers high‑quality, scalable platform services while contributing significantly to infrastructure design, developer experience thinking, and delivery practices. Operating with a high level of autonomy, this role demonstrates strong platform engineering fundamentals, participates in shaping architectural decisions, and supports engineering teams in achieving predictable, value‑led delivery. The Platform Engineer III applies advanced capability across Product, Delivery, and Engineering, helping uplift peers and contributing to ENSEK’s platform-first engineering culture.

Delivery

Break down large platform initiatives into incremental, testable slices that unlock early learning and value.

Contribute to accurate estimation and planning, highlighting risks and dependencies.

Promote agile ways of working and challenge behaviours that hinder flow and predictability.

Communicate clearly, simplify complex platform concepts, and produce golden path documentation so teams can self-serve.

Engineering Practices

Write high‑quality, maintainable infrastructure-as-code and platform tooling aligned to ENSEK standards (e.g. Terraform, Crossplane, Helm).

Contribute to platform architectural discussions; propose cloud-native design options with strong reasoning, including EKS, GitOps, and self-service patterns.

Apply test‑first approaches and contribute to robust testing strategies for platform tooling and infrastructure changes.

Improve observability, alerting, and operational practices across platform services to ensure reliability for all engineering teams.

Advocate secure coding and infrastructure practices, including least-privilege access and supply chain hygiene, ensuring compliance with ENSEK’s policy.

Engineering Community

Share platform knowledge widely, contribute to guilds, and elevate engineering and infrastructure standards.

Mentor junior engineers, support skill development across the team, and help onboard engineering teams onto platform capabilities and golden path tooling.

Participate in platform and community improvement initiatives, champion golden path adoption, and uphold ENSEK engineering values.
