Job description

Jora New Zealand will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

At Halter, we're on a mission to enable farmers and graziers to run the most productive and sustainable operations. Our customers are using Halter to break free from the time-intensive constraints of conventional practices. Imagine watching 500 cattle stand up and walk calmly towards their next break? No quad bikes, no dogs, no fences. Just a group of cattle walking at their own pace. People say it looks like magic. Our customers are revolutionizing grazing with Halter. It's changing lives and transforming an industry. People join Halter to do meaningful work. By joining us you'll be solving challenging problems within a talented team and a culture built for high performance. Our team out-think, out-work and out-care. We're committed to delivering real change in the world - this isn't easy, and in truth, we love that it's hard.

We're backed to deliver on a mission that matters by Tier 1 investors including Founders Fund, Bessemer Venture Partners, BOND, DCVC, Blackbird, Promus Ventures, Rocket Lab's Peter Beck and Icehouse ventures.

About the Role

Every dollar the team spends on paid and organic ends up in one place: the website. This role builds the thing that converts it.

You own Halter's website - as an engineer. In the short term that means owning and building in Webflow: shipping landing pages, components, and experiments fast. But the bigger prize is the migration. You'll scope and lead Halter's move off Webflow to a custom, headless-CMS-backed site, then own it as a codebase - fast, flexible, and built to scale across New Zealand, Australia, and the US.

You own the conversion rate that turns visits into leads. The channel owners drive traffic; you own what happens when it lands - page experience, lead forms, load speed, and the technical and on-page SEO that keeps the site fast, crawlable, and ranking. And you're the build partner for ABM: when the Search, SEO & ABM owner needs a personalised landing experience for a target account, you build it to brief.

This is the highest-leverage lever on the team: a better-converting, faster-shipping site multiplies the output of every other channel. You report to the Performance Marketing Lead and own the conversion rate and lead-quality numbers.

You'll do it with AI as a core tool. Page builds, component generation, copy, and test analysis - we expect you to use AI to ship faster and sharpen every output. You know what an MCP server is, and you've automated real work with tools like n8n.

What We're Looking For

• We don't care where you've come from - front-end engineering, growth engineering, web dev, or a designer-developer who ships production code. What matters is that you build fast, and that you've moved a conversion rate and can prove it.
• You're a front-end engineer. You're fluent in modern front-end - React/Next.js, TypeScript, HTML/CSS - and component-driven build, and you've worked with a headless CMS. You can own a website as a codebase, not just a page builder.
• You can run a migration. You've moved a site - or a meaningful chunk of one - from a hosted platform to a custom build, and you know how to do it without tanking SEO, performance, or the pipeline on the way.
• You're an experimenter. You form a hypothesis, run a clean test, read the result honestly, and ship the winner. You build knowledge, not opinions.
• You care about the whole journey. You don't stop at the form submit - you track results through the funnel and follow up with the wider team to fix problems wherever they surface, even when they're further down the funnel than your page.

What Your Day Could Look Like

• Building and shipping a new landing page - in Webflow today, in your own components tomorrow - and getting it live in hours, not weeks.
• Scoping the headless migration: choosing the stack and CMS, mapping the URL and SEO plan, and sequencing the move so nothing breaks.
• Designing and shipping an A/B test on a key landing page, then reading the result and rolling out the winner.
• Rebuilding a lead form to cut friction and improve quality, then handing a clean lead off to the right downstream flow.
• Working with the Paid Social owner to fix a landing page that's dragging down an otherwise strong campaign, and with the Search owner on technical SEO and page speed.
• Building a personalised landing experience for a target enterprise account to an ABM brief.

You'll Crush This Role If You

• Own the conversion rate. You're accountable for turning traffic into leads, and you treat the site's conversion rate and lead quality as your number.
• Build fast and for real. You ship production-quality pages and components - in Webflow now, in a custom headless stack next - and you can own the migration end-to-end.
• Test your way to the answer. You run disciplined experiments, kill what doesn't work, and ship what does. You don't operate on opinions - you build knowledge.
• Are AI-native. You know what an MCP server is, you've built things with tools like n8n, and AI is already core to how you work.

Bonus Points If

• You've owned website conversion or growth engineering in a high-growth SaaS, hardware, or ag-tech business.
• You've built in Webflow beyond content - whole pages, custom components, and interactions - and know where it stops scaling.
• You've led or shipped a migration to a headless CMS (Contentful, Sanity, Storyblok, or similar) on a modern framework.
• You've run a structured experimentation program with a real testing cadence.
• You're strong on technical SEO, Core Web Vitals, and page performance.
