About the Role

As a Senior Delivery Business Analyst, you will lead complex analysis across balancing, ensuring that problems, user needs, business rules, processes, data and requirements are understood and translated into coherent, testable and operationally viable outcomes. Alongside hands-on delivery analysis, lead the application of process design across delivery initiatives, ensuring that user needs, business rules, data, technology and operational processes are designed as a coherent end-to-end system which delivers measurable business outcomes.

You will provide direction to analysts to select and apply the right techniques rather than treating process design as a separate discipline. You will set clear expectations for analysis quality, provide peer review, coaching and practical assurance across delivery squads, and elevate material gaps that could affect value, delivery or operational readiness. Working with Principal, Discovery and Delivery Business Analysts, you will strengthen reusable standards, evidence and knowledge while remaining an active practitioner accountable for high-quality analysis from delivery shaping through testing, adoption and benefits realisation.

This role is based in Wokingham on a full-time basis. You will need to attend your primary office location at least 2-3 times per week.

This role comes with the following travel expectations:

• Occasional travel to other NESO offices including Warwick, London and Glasgow
• Occasional travel for external conferences / seminars in the UK and abroad

We continue to offer hybrid working and are open to discussions around flexible working arrangements.

This role is designated as requiring a National Security Vetting (NSV) clearance. You will usually need to have been a resident in the UK for the last five years to apply for the required level of clearance.

Key Accountabilities

Value and Outcome-Focused Delivery:

• Lead the delivery analysis approach and activities across assigned products and programmes, selecting a proportionate range of Business Analysis techniques and translating agreed outcomes into coherent increments, user and business needs, business rules, requirements, acceptance criteria and supporting models.
• Elicit, analyse, validate and manage requirements throughout delivery, resolving ambiguity and ensuring that functional and non-functional needs are clear, prioritised, testable and understood by delivery and operational stakeholders.
• Ensure analysis maintains traceability from the original problem and intended outcome through user needs, business rules, processes, data, capabilities, requirements, delivery and measurable benefits.
• Assure the quality and readiness of analysis outputs, support testing and business acceptance, and validate that delivered changes address the agreed need and can be adopted safely by operational teams.

Stakeholder Engagement & Collaboration:

• Build trusted relationships across product, delivery, operations, architecture, data and change teams, ensuring decisions reflect end-to-end business and user impacts.
• Work closely with the Discovery Business Analyst team to assess and scope new initiatives, agree the evidence and outputs needed for delivery, and ensure smooth, traceable handovers between Discovery and Delivery.
• Lead workshops and structured analysis, provide expert guidance, and constructively challenge scope, sequencing and proposed changes where they do not support the intended outcomes.
• Provide clear visibility of progress, risks, issues, assumptions and dependencies, escalating decisions that affect value, operational readiness or cross-team outcomes.
• Engage effectively with operational stakeholders who operate Great Britain's electricity grid as a 24/7 service, ensuring analysis, engagement and delivery planning reflect operational constraints, safety, continuity and readiness needs.

Process Design and Operational Readiness:

• Lead the design of end-to-end business processes across products, services and operational value streams.
• Establish and maintain process modelling standards, governance and quality assurance practices.
• Ensure process designs align to business objectives, user needs, operational constraints, controls and performance measures.
• Define process success measures and validate that delivered changes achieve intended operational outcomes.
• Support the development of process architecture and maintain traceability between value streams, capabilities, processes, requirements and delivered solutions.

Active Delivery Leadership and Knowledge Sharing:

• Work as an active member of the Delivery Business Analyst team, taking ownership of complex analysis while helping colleagues succeed through pairing, practical coaching, constructive feedback and sharing proven approaches across the full Business Analysis toolkit.
• Establish and operate proportionate peer review, analysis health checks and quality assurance across delivery squads, covering evidence, requirements, process, data, business rules, traceability, testability and operational readiness.
• Agree improvement actions with analysts and delivery leaders where quality gaps are identified, and elevate material risks where inadequate analysis could affect outcomes, delivery confidence, operational safety or benefits realisation.
• Lead by example in creating and maintaining reusable business rules, process and data knowledge, working with colleagues to keep content current, traceable, accessible and governed through clear ownership and change control.
• Identify recurring quality and capability gaps, develop targeted guidance and learning, and use assurance evidence and feedback to strengthen Business Analysis practice across the community.
• Work alongside Product Owners and product teams to shape and prioritise the backlog using evidence, user needs, operational value and dependencies; define minimum valuable increments and success measures; and use adoption, efficiency and benefits evidence to drive continuous improvement.

Applicants must have the right to work in the UK by the start of employment. Visa sponsorship may not be available for this role and will be considered in line with business requirements.
