Job description

Together we're building a greener tomorrow

Connecting every home and business to a single, secure smart meter network is a huge undertaking. So you can imagine the scale – and variety – and opportunities for the people who'll help us do it.

The role

Senior Domain Architect (SMETS1) / Hybrid: Manchester or London

Own the technology strategy and architecture roadmap for a mature, business-critical smart metering service. You will shape the long-term sustainability of the SMETS1 estate, balancing resilience, security, risk, cost and business value while influencing suppliers and senior stakeholders.

About the DCC

We're powering Britain's smarter, greener future. Today. Tomorrow. Together.

Today, we're deeply invested in building a resilient, sustainable smart energy network that drives transformation. Our success is driven by curiosity, ambition, and tenacity.

Tomorrow, we see vast opportunities for growth and development, contributing to decarbonisation and the Net Zero mission. We'll continually develop Smart DCC, to fulfil our obligations to consumers, and achieve even more with our customers, partners, and each other. Join us and development opportunities range from talent programmes, academies and always on learning to exposure to senior stakeholders and industry experts, contributing to complex projects and constant support to drive your own development.

Together, we embrace change, unite in our shared passions and support each other. Working as one team and across our industry, we rise to the challenge to shape Smart DCC, and the future.

A career at Smart DCC means being part of something bigger – a dynamic organisation that’s not just helping transform energy but also shaping the future. We offer a unique, fulfilling environment where you can thrive today, develop for tomorrow, and achieve together.

How you will contribute to transforming the smart energy network and shaping the future.

• Own and govern the SMETS1 technology strategy, architecture and roadmap, ensuring decisions support service sustainability, regulatory obligations and future transition and retirement planning.
• Lead architecture assurance across applications, infrastructure, cloud services and device technologies, ensuring solutions align with enterprise architecture standards and best practice.
• Manage architectural risk across the SMETS1 estate, including technical debt, obsolescence, resilience, security and cross-supplier dependencies, driving proportionate mitigation strategies.
• Review, challenge and influence supplier architecture, roadmaps and technical solutions to improve outcomes, value for money and alignment with DCC strategy.
• Act as a trusted technical authority for internal and external stakeholders, translating complex technical choices into clear recommendations based on business value, risk and operational impact.

What you need to bring:

• Strong enterprise or domain architecture experience in complex, large-scale technology environments, with ownership of technology roadmaps and architecture governance.
• End-to-end systems thinking, including experience designing and assuring solutions across cloud, infrastructure, applications and system integrations.
• Experience managing technology lifecycle challenges such as legacy platforms, technical debt, obsolescence, resilience, migration or transition planning.
• Commercially aware stakeholder and supplier management skills, with the credibility to challenge, influence and communicate technical decisions to senior and non-technical audiences.
• Experience of smart metering, SMETS1 or another large-scale regulated operational service is highly desirable and will enable you to make an impact quickly.

While our mission is ambitious, we also prioritise balance offering flexibility and support to help you thrive both personally and professionally. At DCC we reward fairly and recognise fully because our continued success depends on our people.

We also offer a competitive 8 days per month hybrid work policy for most roles as well as competitive salaries with regular benchmarking, bonuses tied to personal and company performance. Our core benefits include pension, generous leave allowance, private healthcare and range of flexible benefits that you can tailor to you.
