About this role

Newton is one of the UK's leading consulting firms, known for its data-driven, results-focused approach to solving complex business challenges. We partner with organisations across the public and private sectors to deliver measurable, sustainable improvements through a distinctive commercial model: our fees are contingent on delivering agreed outcomes.

As Newton expands into Australia, this is a unique opportunity to join at a pivotal stage of growth. You will help build our Australian business by developing trusted client relationships, leading high-performing teams, and delivering lasting outcomes for defence clients.

Our teams lead intensive diagnostics and multi-year transformation programmes, taking end-to-end responsibility for identifying opportunities, designing solutions, and embedding sustainable change. As a Lead or Principal Consultant, you will lead complex workstreams, manage multi-disciplinary teams, build strong client relationships, and deliver $2m–$5m+ in client value.

The role is incredibly varied but would typically cover, but not be limited to:

· Working closely with programme leads to ensure workstream KPIs are aligned to client organisational outcomes and wider transformation objectives

· Working on site in different Australia locations, day to day with client counterparts to review progress, problem-solve and drive performance improvement, while building lasting client capability. We are happy for you to be based anywhere in Australia with a good airport nearby.

· Creating clear, compelling and data-driven stories for stakeholders – from frontline managers through to senior leaders and executive sponsors – and working with programme leads to remove blockers to progress

· Proactively adjusting delivery, resourcing and commercial plans in collaboration with programme leadership to keep workstreams and programmes on track

· Identifying opportunities for future work within your client area and supporting wider account and market engagement activities alongside programme and account leadership 

· Prior consulting experience in operational excellence and outcome-focused delivery.

· Demonstrated experience delivering complex transformations within the defence sector.

· Managing teams of consultants of various levels, capability areas and across different workstreams

· Building and maintaining trusted relationships with senior managers, heads of function or programme, with competence and confidence to present in front of client executives

· Purpose led analysis skills and ability to use logic to solve a problem

· Ability to compellingly present assessment and programme outputs to enable successful progression of next steps

· Running day to day internal and client facing governance

· Resilience in solving highly complex problems

· Collaborative nature, working with internal and external teams to get to the best outcome together

· Proven track record for driving improvement or impact with an outcome focused mindset

· Big picture thinking and the ability to connect the dots using relevant market themes

· Starting to think more commercially by spotting potential opportunities and understanding and communicating potential risks

· Willingness for self-development and commitment to supporting the development of others around you; actively seeks and gives feedback

· Ambitious and driven; always strives for the best outcomes for self and others

· Flexible and willing to work away from home
