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.
As a Project Manager at ENSEK, you’ll be a driving force behind the successful delivery of complex enterprise client projects across the energy sector. You’ll own complex technology driven projects end‑to‑end — from mobilisation through delivery and handover to BAU — ensuring outcomes are delivered on time, on budget and to a high standard of quality.
This is a hands‑on delivery role. You’ll lead clients confidently, coordinate cross‑functional teams, manage risks proactively and keep momentum high. Working across a diverse client base — from Tier 1 organisations to fast‑growing start‑ups — you’ll focus on execution, value creation and getting the best out of people.
