Senior Software Engineer

Te Tākinatanga - Our Story   

At Contact, we believe home is the most important place in the world. That belief shapes everything we do, from leading the energy transition to how we power Aotearoa and care for our people and communities. 

We’re a power, broadband, and mobile company, but we’re also investing boldly in renewable energy and smarter, more connected ways of working (mahi). Our ambition is simple: to leave Aotearoa better than we found it. 

Guided by our tikanga, we’re a team who care deeply about the work we do, how we support one another, and the impact we have. Simply put, we touch lives to make life better. 

Technology is central to our ambitions, enabling safe, reliable operations today while modernising how we work, strengthening our data foundations, and building resilience for the future. 

Te Whiwhinga mahi | The Opportunity   

As a Senior Software Engineer, you'll be a key technical leader within a cross-functional squad. You'll balance hands-on development with shaping how solutions are designed, built, and evolved. 

You’ll work closely with Product, Design, Architecture, and business teams to turn ideas into well-engineered, scalable solutions that support both our customers and our people. 

This is an opportunity to have real impact — the systems you help build will underpin how Contact operates day-to-day and into the future. 

What you’ll be doing 

• Leading technical design and contributing to key engineering decisions 
• Ability to help shape and uplift the .NET practice through technical leadership, best practices, mentoring, and establishing scalable engineering standards. 
• Building robust, scalable software across modern technology stacks 
• Partnering with cross-functional teams to deliver fit-for-purpose solutions 
• Influencing integration patterns and architecture direction 
• Coaching and mentoring other engineers, lifting team capability 
• Driving a culture of continuous improvement and shared ownership 

This role carries accountability for quality, resilience, and sustainability of the software you help deliver, alongside a genuine commitment to growing capability across the team.
