AI Product Engineer — TypeScript / Angular / Java

New Zealand-based remote contract role | Initial four-month engagement | Possible extension

About the role

HI Technology & Innovation is looking for a New Zealand-based AI Product Engineer for an initial four-month remote contract with a long-standing construction technology client.

This is a hands-on engineering role with a strong product focus. You will work with product and client stakeholders to understand what is worth building, shape practical solutions, and then take ownership of shipping them.

The work is focused, high-energy, and suited to someone who can move quickly while still keeping quality, maintainability, and product value front and centre.

AI is central to how the team works. Modern agentic coding tools are used every day, but they are treated as an accelerant for a strong engineer, not a replacement for one. The important part is knowing what to build, keeping quality high, and making sure what ships is stable and maintainable.

What you’ll be doing

• Working with product and client stakeholders to understand real problems and shape buildable solutions

• Owning features end to end, from early scoping and design through to build, testing and release

• Using AI coding agents to move quickly while staying responsible for code quality, structure and maintainability

• Building and integrating AI-assisted features, including prompts, evaluations and guardrails

• Working from a defined data model and flagging issues early where something does not add up

• Feeding what you learn back into product and client conversations so each iteration improves

What we’re looking for

We’re looking for someone who is part engineer and part product thinker.

You should be able to talk with non-technical stakeholders, understand their workflow, identify the real problem, and translate that into a sensible technical plan.

You’ll likely be a good fit if you bring:

• Strong TypeScript and Angular experience

• Genuine Java strength, especially around API integrations

• Comfort working across front end, back end and data

• Strong product instinct and the ability to ask why something should be built, not just how

• Practical experience or strong fluency with AI coding tools

• Clear communication with product, client and engineering stakeholders

• Good judgement around quality, maintainability and long-term stability

• Ability to own work end to end without needing every next step defined

Tech stack

The core stack includes:

• TypeScript with Angular

• Java, with some Python

• Google Firebase

• PostgreSQL

• Google Cloud Storage

You do not need to have used every part of the stack, but strong Java, modern TypeScript and Angular will set you up well.

Working arrangement

This is a remote New Zealand-based contract role.

The client and wider team are based in the United States, so some daily overlap with the US west coast may be needed. The exact working pattern will be agreed together.

The initial engagement is expected to run for around four months, with the possibility of extension if things go well.

How to apply

Please apply with:

• Your CV

• A short note about a product or feature you are proud of

• The part you played in deciding it was the right thing to build

Applications will be reviewed through the formal recruitment process.
