Software Engineer

Ko wai te Pakihi nei | About the Organisation Sharesies is a growing New Zealand tech company with a clear mission to provide financial empowerment for everyone. As part of its next growth phase, Sharesies is investing further into its in-house engineering team. Rather than outsourcing critical work, Sharesies is investing in building, owning, and scaling the core systems that sit at the heart of the business. The culture is ambitious but grounded. Engineers are encouraged to challenge the status quo, be curious, understand the why, and focus on delivering value. The structure is relatively flat, progression is based on capability rather than tenure, and there’s a strong belief in balancing healthy pressure with genuine care for people. They’re proud of the culture they’ve created and have been recently recognised as one of the best places to work in New Zealand. Ko te āhua o te tūranga | About the Role We’re looking for an experienced Senior Software Developer to join a product engineering team building and evolving a modern platform (within Sharesies Personal) that supports Sharesies’ investing products. This team manages Sharesies Investing products, including the original Investing product, tax, corporate actions and crypto (among plenty of other things). The team sits within the same business unit as Spend, Protect and Save, so it’s a busy, high-impact environment. This is a technically interesting product environment. At its core, the platform acts as a trusted system of record for legally and financially significant data. Accuracy, security, auditability and reliability are fundamental to how the software is designed and built. As a Senior Software Developer, you’ll work as part of a cross-functional product team to design, build and improve the services, APIs, workflows and user experiences that underpin the platform. Everyone writes code. Python is the primary language, but prior Python experience is not essential if you’ve demonstrated the ability to learn new technologies quickly. Experience across more than one language (for example Python, C#, TypeScript/JavaScript) is valued more than deep specialisation in a single stack. The environment is predominantly Python and C# on AWS; however, Sharesies is technology agnostic. What matters most is strong engineering fundamentals and the ability to learn quickly. What You’ll Be Working On You’ll contribute across the lifecycle of the product, including:Designing and developing scalable backend services and APIsBuilding functionality that supports complex transactional workflows and high-integrity dataDeveloping secure and reliable handling of sensitive customer and financial dataDesigning systems where transaction history, traceability and auditability are criticalBuilding integrations with internal and external platforms and (where relevant) regulatory servicesImproving platform performance, resilience, observability and scalabilityContributing to the ongoing evolution of the architecture as the product growsWorking closely with Product, Design, Engineering and other stakeholders to turn complex requirements into well-designed software Mōu | About You We’re looking for a strong senior engineer who is comfortable solving complex problems rather than simply implementing predefined requirements. You’ll Ideally Bring Strong commercial software development experience, including operating at Senior Developer / Senior Software Engineer levelStrong backend engineering capability and experience building production-grade applicationsExperience designing and developing APIs, services and integrationsStrong understanding of relational data modelling and transactional systemsExperience designing systems where data integrity and consistency are importantGood knowledge of modern cloud architecture and engineering practicesExperience with automated testing, CI/CD and modern software deliveryA strong understanding of application security and secure development practicesExperience diagnosing production issues and improving application reliability and performanceThe ability to work effectively within a cross-functional product teamStrong communication skills and the ability to explain technical decisions and trade-offs clearlyNice to have (but not essential): PostgreSQL, Terraform, Docker, AWS services (EC2/ECS/S3/RDS), web application security, and experience in financial or investing systems. Senior-level expectations This is a hands-on engineering role, but seniority is more than writing code. You’ll be expected to: Take ownership of complex technical problems from discovery through to productionContribute to architecture and technical design decisionsIdentify risks around data integrity, security, scalability and maintainabilityMake pragmatic engineering decisions and clearly articulate the trade-offs involvedReview code and help maintain a high engineering standard across the teamMentor and support other developersCollaborate with Product to shape solutions rather than simply receive requirementsHelp break complex domain problems into sensible, deliverable incrementsImprove engineering practices and contribute positively to the wider engineering culture Tauwāhi | Location & Flexibility Wellington is preferred. Auckland-based candidates and flexible working arrangements are considered. New starters are expected to spend time in Wellington initially to become well embedded in the team and culture. Sharesies offers a flexible working environment, but they also have a genuine office culture, so being present and building strong relationships in-person is important.
