Job description

Senior Developer – Web Platform & Digital Applications

18 Month Fixed Term Contract!
We're looking for an experienced developer who loves building high-quality web applications, designing practical digital experiences, and solving real business problems through technology.

We're a New Zealand-based business with a mix of frontline and back-office teams. Like many established businesses, we have a core legacy ERP, operational processes that have evolved over time, and a significant opportunity to modernise how systems connect, how data moves through the business, and how our customers and staff interact with our platforms.

This role sits in the middle of that journey: web applications, customer and staff portals, mobile platforms, integrations, and practical software engineering.

What You’ll Work On

You’ll help design, build, and improve systems across the business, including:

• Customer and partner facing web applications and portals
• Internal business applications and operational tools
• React-based user interfaces and frontend architecture
• Integration with our mobile application ecosystem
• APIs, backend services, and data integrations
• Digital services connecting modern platforms with legacy business systems
• Platform capabilities that support automation and operational efficiency
• New ideas, prototypes, and solutions that can become production systems

Our current technology mix includes React, TypeScript, Supabase, PostgreSQL, Azure, iOS applications, Python, Java, and related integration and automation tooling. Experience with these technologies is beneficial, but we care more about capability than matching every keyword.

The Team

You'll be joining a small software engineering team where each senior developer drives a primary technology domain while contributing across the broader platform. While each developer has a clear area of accountability, we deliberately avoid hard technical silos. We believe specialists are most effective when they understand how the wider platform works and are willing to contribute outside their primary domain when required.

Current areas of ownership broadly include:

• Mobile Applications
• Automation & AI
• Integration & Infrastructure
• Web Applications

What We’re Looking For

We care less about a perfect CV and more about how you think, build, and solve problems.

You’ll likely be a good fit if you:

• Have strong commercial experience with React and modern web development.
• Understand full-stack application architecture.
• Are comfortable working with APIs, databases, cloud services, and application deployments.
• Can take a vague business problem and turn it into a practical solution.
• Understand that business systems are often interconnected, imperfect, and constantly evolving.
• Care about delivering useful outcomes rather than pursuing technical purity.
• Can work independently, make sensible technical decisions, and communicate clearly.
• Enjoy understanding how systems fit together rather than focusing exclusively on a single technology layer.
  

Seniority & Independence

This is a senior role requiring a high degree of technical maturity and professional judgement. Success in this role requires initiative, sound judgement, curiosity, and the confidence to move work forward in situations where requirements are not always fully defined.

You will be trusted to:

• Work independently with minimal supervision.
• Take ownership of outcomes rather than simply completing assigned tasks.
• Make informed architectural and implementation decisions.
• Balance technical quality, delivery speed, and business value.
• Collaborate effectively across technical and non-technical teams.
• Identify risks, opportunities, and trade-offs early.
• Seek input when needed without becoming dependent on constant direction.
• Help shape technical direction within your area of responsibility.

Strongly Preferred Experience

Any of the following would be highly valued: Applications with commercial iOS development experience will be particularly attractive, given our existing mobile platform and the close relationship between our web and mobile applications.

• Commercial React and TypeScript development
• Maintaining or evolving production mobile applications
• Supabase and PostgreSQL
• Azure or cloud-hosted applications
• API design and integration
• Authentication and identity platforms
• Legacy ERP or business systems integration

The Curiosity Factor

This remains important to us. We're looking for someone who genuinely enjoys technology beyond simply completing assigned work.

That doesn't mean working unreasonable hours. It means you're naturally curious. You might build personal projects, self-host systems, experiment with new frameworks, automate repetitive tasks, explore AI tooling, run a home lab, or simply enjoy understanding how technology works. We want people who enjoy learning, exploring, and improving their craft.

What Success Looks Like

In this role, you’ll be trusted to:

• Own and evolve our web technology strategy.
• Deliver high-quality customer and staff-facing web applications.
• Establish consistent frontend architecture and development standards.
• Collaborate effectively across mobile, automation, infrastructure, and integration domains.
• Contribute to platform-wide technical decisions.
• Share knowledge and help strengthen the wide engineering team.
• Own problems from idea through to implementation.
• Bring practical technical judgement, maturity, and energy to the business.
  

Why Join Us?

This is not a narrow role focused solely on delivering tickets. You’ll work across real business problems involving web applications, mobile platforms, integrations, automation, business systems, customer experiences, and operational processes.

There is plenty to improve, modernise, connect, and build. We’re looking for someone who wants to understand the business, get close to the problems, and create practical technology that delivers visible value.
