Whether it’s a Friday‑night feast, a post‑gym poke bowl, or grabbing groceries, our tech platform connects tens of millions of customers with hundreds of thousands of partners across the globe.

We’re looking for a Principal Product Manager to join our Platform organisation, taking on a newly created and highly impactful role focused on experimentation. You’ll sit at the heart of JET’s global product ecosystem, partnering closely with senior product and tech leaders to define how experimentation shapes our future.

In this role, you’ll champion a data‑driven mindset across the business, enabling our teams to move faster, make smarter decisions and unlock long‑term, scalable growth. You’ll work with stakeholders, product leaders and end users across multiple markets, helping us challenge what’s possible while keeping customers at the centre.

Aligned with our values of lead, deliver and care, you’ll help shape the next generation of decision‑making at JET – bringing clarity, structure and excitement to how we test, learn and innovate.

These are some of the key components to the position:

• Partner with senior product, tech and global stakeholders to define the vision and strategic direction for experimentation across JET.
• Build measurable success criteria that link experimentation outcomes directly to value and business impact.
• Translate complex product and organisational challenges into simple, compelling narratives that secure alignment and momentum.
• Act as the voice of internal users by researching, listening and validating opportunities to ensure experimentation solves real needs.
• Operationalise the experimentation strategy, scaling processes, tooling and mindset across teams and markets.
• Collaborate with ambassadors and product teams to champion experimentation, promoting hypothesis‑driven thinking over opinion‑based decision‑making.
• Drive excellence by shaping experimentation frameworks across front‑end and back‑end testing including A/B, MVT, switchback, sample sizing and geo‑based testing.
• Partner with engineering, data, design and market teams to continually raise the bar on how we test, measure, learn and improve.
• Influence senior stakeholders across the organisation to build alignment and shift behaviours toward a culture of informed, data‑driven experimentation.
• Move fast, iterating quickly, unblocking teams and delivering scalable experimentation capabilities that create lasting impact.

What will you bring to the team?

• Experience building and optimising platform products, grounded in clear measures of success and the ability to adapt rapidly.
• Deep expertise in experimentation methodologies; A/B, MVT, sample size calculation, feature flags, switchback testing, geo‑based tests and more.
• Strong understanding of commercial and trading experimentation, with the ability to balance speed, impact and rigour.
• Ability to introduce AI‑driven capabilities that improve workflows, guide decision‑making and enable smart self‑service.
• Excellent collaboration skills, able to influence and align senior stakeholders across a global organisation.
• Clear, value‑driven thinking that ties product strategy and decisions to measurable outcomes.
• Comfort with complexity and ambiguity while maintaining focus, structure and clarity.
• A bias for action, moving quickly, learning often and delivering impactful change at pace.
• Experience working across product, engineering, data, design and local markets in dynamic, high‑growth environments.
• Strong communication skills with the confidence to challenge assumptions, inspire teams and elevate standards.

At JET, this is how we play. Our teams forge connections internally and work with some of the best‑known brands on the planet, giving us truly international impact in a dynamic environment.

Being the best at what we do isn’t just about delivering on our strategy. It’s a competition for something incredibly valuable – our customers' choice. Every time a customer decides where to order, they’re picking a side.
