Job description

We're a workplace that truly values people and everything they bring to the table. We strive for industry-leading thinking and we're well on our way to creating financial empowerment for everyone with over one million people across Aotearoa and Australia choosing Sharesies to invest, save and work toward their long-term wealth with KiwiSaver. Want to join us?

We're thrilled to announce an exciting opportunity for a Staff Engineer to join us! You'll enjoy a highly varied role, working to support Sharesies' ambitious goals and ensure we continue to deliver at pace.

This position offers exposure to challenging problems where you'll have the power to make impactful decisions. You'll spend much of your time doing hands-on development work, balancing quarterly priorities with the flexibility to put time into your own initiative where you see payoff. You'll also provide expert guidance to other teams about the systems we anchor.

If you're driven by the challenge of tackling complex problems, eager to influence how we do tech at Sharesies, keen to work with a highly capable team and excited by a role that offers both breadth and depth, we warmly invite you to apply.

For the Staff Engineer role we are specifically looking for someone who:

• has excellent full stack development skills (our stack is primarily Python and Typescript/React, and some C#)
• has the ability to consider both business context and technical strategy and constraints, and drive solutions that meet both
• has a knack for coming up with simple and scalable solutions for really complex problems
• is a keen learner and strong problem solver, with the ability to help teams navigate healthy disagreements about approach and requirements
• has good communication and people skills, including mentoring and reviewing work
• is adaptable to change, and is motivated by our vision and purpose

At Sharesies, we believe in the power of belonging, and we're committed to a culture of inclusion. If you're super keen to work with us but not sure you have the exact right experience, or you're interested in part time hours, we'd love to hear from you anyway!

This job closes at 5pm, Monday 21 September 2026.
