Senior BA / Technical BA

Mō te tūranga | About the Role 
As a Senior Business Analyst, you will help shape and deliver meaningful change by working across product, operations, technology, engineering, risk and design to turn business needs into clear, achievable outcomes.

You will lead analysis from early discovery through to delivery. This includes defining problems and outcomes, exploring process, data, system and customer impacts, clarifying requirements, assessing options, and maintaining alignment as solutions evolve.

This is a hands-on senior role. You will bring structure to ambiguity, facilitate effective decisions, communicate complex information clearly, and support others to lift the quality and consistency of analysis across the work.

• Lead discovery and analysis to define the problem, desired outcomes, scope, assumptions, constraints and measures of success.
• Elicit, analyse, prioritise and document business, customer, process, data and system needs, selecting fit-for-purpose techniques for the work.
• Translate needs into clear business and functional requirements, detailed user stories, acceptance criteria, models and other analysis artefacts, with traceability through delivery.
• Analyse current and future-state processes, customer journeys, business rules, information flows, integrations and system impacts.
• Partner with Product Owners, delivery leads, engineers, testers, designers, change practitioners, risk specialists and frontline teams to refine options and support quality delivery.
• Facilitate workshops and decision-making forums that surface perspectives, resolve ambiguity and build shared understanding.
• Identify dependencies, risks, gaps and operational impacts early, and support practical plans for business readiness, change adoption and transition.
• Support option assessment, supplier evaluation, business cases, benefits measures and governance artefacts where required.
• Keep analysis current, proportionate and accessible so teams can make informed decisions and maintain shared understanding.
• Provide thought leadership and influence decision-making by bringing analytical rigour, evidence and customer perspectives to complex business challenges.
• Coach and mentor analysts, share effective practices and contribute to continuous improvement of the Business Analysis craft.

• A future-focused mindset, with the curiosity and confidence to leverage AI and emerging technologies to enhance decision-making, accelerate delivery and elevate Business Analysis practices
