Senior Product Engineer

Nylon is the AI research platform for tax and law professionals.

The tool practitioners reach for when the answer has to be right. We're used by 2,000+ firms across NZ, AU and the UK, backed by Blackbird, and expanding fast beyond research into the wider workflow professionals live in: client meetings, documents, the tools firms already use.

Product engineers at Nylon own a product stream end to end. Not a ticket queue or a component: a customer problem, and the outcome for the firms that have it.

You'll talk to accountants and lawyers, work out what actually makes a difference to their day, decide what's worth building, build it, ship it, then go back to the customer who asked for it and find out whether it worked.

• You talk to customers every week: calls, onboarding sessions, support threads. You'll have customers you know by name and can ring to test an idea.

• You decide what to build. You weigh customer pain, usage data and commercial impact, and make the call with product instead of waiting for a spec.

• You ship early. Get a rough version in front of real users, then iterate on what they actually do, not what they said they'd do.

• You own the result: adoption, retention and revenue for your stream, not just whether it shipped. That includes production health, observability and the occasional incident.

• You work full stack, including the UX. You design the first version yourself with our design system and bring in design when it's worth polishing.

• AI-native. Agentic dev tooling (Claude Code) is the development loop.

• Async-first. Effective writing is a key skill.

• No prescribed solutions. We agree the problem and the constraints; how you solve it is yours.

We care about evidence of ownership more than years, though you've likely shipped commercial software for 5+ years.

We hire product engineers at every level. We set the level through the interview, not the title on your CV.

• You've taken something from a customer conversation to production and can tell us what changed for them

• You'd rather talk to a user than guess, and you're comfortable on a call with a partner at an accounting or law firm

• High agency: you own outcomes, not tasks

• You reason in trade-offs, technical and commercial, out loud and in writing

• You already use AI tooling to ship faster, and you're curious about where that goes next

• Show us something you built because you wanted it to exist (a repo, an app, a product or a business all count)

• Bonus: you've worked in or alongside accounting, tax, law or another professional-services world

What we run today. Experience with it helps; it isn't a filter.

• AWS, Terraform, Docker

• Jest, GitHub Actions, Datadog
