About Us
At the National Energy System Operator (NESO), we play a vital role in tackling climate change and securing Great Britain's energy future. We already operate the world's fastest decarbonising electricity system and are working towards our ambition to run it carbon‑free for a short period this year – provided the market supplies electricity exclusively from renewable sources. Alongside this, we provide expert advice to government on how to deliver a clean power system by 2030. In autumn 2024, the Electricity System Operator (ESO) transitioned to become NESO – an independent, expert public corporation with a whole‑system view across electricity, gas, and hydrogen. Licensed and regulated by Ofgem, we make impartial decisions that balance sustainability, affordability and security, and operate independently of government and commercial interests.
About The Role
National Energy System Operator (NESO) recognises the potential of bright and talented individuals, and we encourage you to join us as Great Britain’s energy system undergoes an ambitious, exciting, and vital transformation. Together with industry, we are creating a cleaner, more sustainable energy future. The Resilience & Emergency Management (REM) directorate strengthens whole‑energy‑system resilience by being a catalyst for change – turning insight into coordinated, prioritised action that reduces risk and builds capability across the system. REM delivers this through analysis, assessments, reviews, emergency exercises, and plans that drive tangible improvements with our partners. This role is to develop and apply advanced approaches for understanding and modelling complex, cascading risks across the energy system, enabling NESO to anticipate how interdependencies and shocks can propagate and to drive more effective, system‑level resilience improvements. This role can be based from Wokingham, Warwick, or Glasgow, and we continue to offer hybrid working from office and home. We are open to full‑time and part‑time applicants, as well as flexible working arrangements.
Key Accountabilities
* Define and establish NESO’s capability for analysing and understanding complex, cascading, and interdependent risks across the energy system
* Build and lead a specialist team focused on innovative approaches to modelling, simulating, and interpreting cascading system risks
* Identify and assess complex cascading risks of the energy system and how failures propagate across energy vectors, sectors and time horizons using novel analytical approaches
* Ensure analytical findings are supported by robust technical understanding of the physical energy systems
* Develop and apply methodologies that move beyond isolated assessments to reflect whole‑system behaviour, interdependencies, and feedback effects
* Generate strategic insights from complex risk analysis that inform prioritisation, preparedness, and long‑term resilience improvement
* Work closely with wider REM and NESO teams to ensure cascading risk insights are integrated into system‑level assessments, narratives, and advice
* Collaborate with other REM teams to ensure advanced modelling complements and strengthens existing risk, security of supply, and preparedness work
* Translate complex analytical outputs into clear, decision‑relevant insights for senior leadership, industry, and government
* Identify opportunities where insights from cascading risk analysis can drive tangible improvements in policy, planning, operational practice, or system design
* Establish partnerships with academic institutions, research bodies, and technology providers to remain at the forefront of complex systems and resilience modelling
* Contribute to the continuous evolution of REM’s analytical capability, ensuring innovation is balanced with credibility and usability
* Ensure modelling methods are robust and best practice in analytical rigour is adopted
* Engage with industry, government, and research communities to share insights and shape thinking on systemic and cascading risks
About You
* Experience in complex systems analysis, risk modelling, resilience analytics, or related disciplines, gained in energy, infrastructure, academia, consultancy, or technology environments
* A strong understanding of why isolated or siloed risk assessments are insufficient in complex, interconnected systems
* Curiosity and confidence to define new approaches, rather than relying solely on established methods
* The ability to balance technical depth with strategic relevance, ensuring insights are credible, interpretable, and useful
* Experience building or leading specialist analytical teams, or a strong aspiration and capability to do so
* Clear communication skills, able to explain complex cascading behaviours and uncertainties to non‑technical audiences
* A collaborative mindset, working effectively across disciplines, organisations, and sectors
* Comfortable engaging with uncertainty, ambiguity, and evolving problem definitions
* A strong sense of purpose around improving the resilience and robustness of the energy system
* You believe that understanding and managing cascading, interdependent risks is essential to building a resilient energy system – and you want to be at the centre of defining how that understanding is developed and applied
* Proven track record of building and or leading high‑performing teams is desirable.
* Knowledgeable of the GB energy system, with relevant engineering, energy, or policy experience – or a willingness to learn and develop this expertise.
What You’ll Get
A competitive salary of £73,000 – £80,000 dependent on experience and capability.
* You will receive a bonus based on company performance
* 26 days annual leave as standard
* A competitive contributory pension scheme where we will double match your contribution to a maximum company contribution of 12%.
* Annual enrollment to NESO Savings Plan – when you save between £20 and £500 a month from your take‑home pay, we will pay a 50% matching contribution.
Benefits
NESO's flexible benefits programme provides you with more flexibility around your health, lifestyle and protection benefits, here are just a few available:
* Flexible Bank Holidays & Holiday Trading
* Additional Birthday Day Off
* Cycle to Work Scheme, Retail & Gym Discounts
* Private Medical Insurance, Critical Illness Insurance & Personal Accident Insurance
