A regional energy utility is expanding the applications that support changing energy use and services for customers in vulnerable situations. As a senior Functional and Technical Analyst, you connect business needs, architecture and delivery across API-connected mobile and web applications, cloud services and core business systems.

The mission

A team of around 15 people manages a digital data hub, an ERP system for vulnerable customers, and mobile and web applications connected through APIs. The landscape supports access to consumption information and the management of energy communities, while adapting to smart meters, local production and electric vehicles.

You will lead functional analysis from requirements elicitation to go-live. You will organise workshops, compare options against IT architecture and the full application chain, document decisions, and act as the link between business stakeholders and development partners. After delivery, you will help manage applications, investigate defects and provide second-line incident support.

Your responsibilities

  • Analyse business needs and facilitate workshops with business and technical stakeholders.
  • Define and document solutions aligned with IT architecture across the E2E application chain.
  • Translate requirements into detailed functional and technical specifications.
  • Review partner proposals and follow delivery from analysis through go-live.
  • Create, coordinate and execute test plans, test cases and UAT.
  • Assess defects, track resolutions and maintain reference documentation.
  • Support application management, problem resolution and second-line incident handling.
