Product Engineer, UK in London

Location: London, United Kingdom

Employment Type: Full time

Location Type: On-site

Department: Product

Partly is headquartered in Austin, TX with offices in London, UK, Christchurch, NZ and Auckland, NZ. Wherever you're based, we'll connect you with your nearest office for onboarding, and fly you to join the full team for our quarterly “Season Openers” (we cover travel and accommodation). If you're relocating to join us, we can also assist with relocation costs. This position is based in our London office.

Our story: Partly's mission is to connect the world's parts and we're doing that by building the first global platform for replacement parts, starting with auto parts. Our big vision is to accelerate the world towards a sustainable future where anyone can fix anything. Founded by ex-Rocket Lab engineers, we utilize cutting‑edge technology to solve challenging but exciting problems that make a huge impact in a $1.9 trillion industry. We've more than tripled our team over the last 12 months and expect to double in size again over the coming 12 months. We're a global team spanning both Europe and Australasia. We provide a scalable digital infrastructure solution to some of the world's largest businesses and the most exciting startups. Partly's solutions are integrated across hundreds of companies globally, providing the backbone for cataloging and managing parts online.

This role: This is a product‑builder role, not a ticket‑taking one. You own a product surface end to end: you talk to the customer, form the idea, build it, ship it, measure it, and decide what happens next. The same person who understands the repairer writes the code. There is no handoff for product quality to leak through. You’ll build at the center of a multi‑trillion‑dollar industry that still runs on phone calls, spreadsheets, and tribal knowledge. Replacement parts is one of the largest physical markets on earth and one of the least digitized, and there is no established playbook to copy. Partly is creating the category.

What will you do:

• Build, not just specify. Prototype new product iterations yourself using AI‑assisted and LLM‑assisted tooling, fast, disposable, real.
• Treat the prototype as the hypothesis and put it in front of real customers before writing the spec.
• Ship production code, instrument it, and watch how it actually gets used.
• Stay close to customers. Spend time where the work happens. Understand what estimators, parts managers, and others actually do, where they lose time, and what better would feel like.
• Reconcile signal. Combine what you see with what the data says, and reconcile the two when they disagree.
• Own the outcome. Steer by your surface’s metrics; adoption and value delivered are yours.
• Make the trade‑off. Weigh product impact against engineering effort in the same breath, and find the cheaper path to the same outcome.
• Build the agentic experience. Move your surface from manual operation toward supervised delegation.
• Hold the craft. The surface feels fast, clear, and considered.
• Raise the bar. Pair with SW Engineers on the harder systems work behind your surface.

Your skills:

• Non‑negotiables:
• You ship end to end: a track record of taking features from idea to production, code included, with clear accountability for whether they worked.
• Roughly 3+ years building and shipping software in production.
• Genuine customer obsession: a real habit of spending time with users in their work context.
• Product taste and craft: experiences that feel effortless to time‑pressured, non‑technical users.
• A point of view on agentic product design.
• You build rapid prototypes yourself, with AI‑assisted tools as a first instinct for testing an idea.
• Solid full‑stack engineering with a frontend lean.
• Trade‑off fluency: you weigh product impact against engineering effort.
• Strong analytical instinct: you define the metric, build the view, read it, and act.
• You operate well in ambiguity and autonomy.
• Strong signals we look for:
• Shipped AI‑assisted or agent‑driven features in production.
• Built for a multi‑persona, operational, or workflow‑heavy B2B product.
• Founder background, or early employee at a startup that scaled materially.
• You’ve killed or radically changed something you personally believed in, and can explain why.
• Bonus:
• Domain knowledge in automotive, the parts aftermarket, repair, or insurance claims.
• Marketplace or network experience, from the demand or supply side.
• Rust, or genuine eagerness to learn it.

Benefits:

• Competitive base salary + equity.
• Annual global offsite in New Zealand.
• Parental leave: Primary caregivers receive 3 months of fully paid parental leave.
• Team lunches: Lunch provided daily (Monday to Friday) in the office.
• Flexible working hours: We have flexible working hours and default to working from the office.
• Season openers & events: We host regular events, including quarterly “season openers” for our UK/EU team.
• Healthy body, healthy mind: Every team member gets a £750 annual wellness allowance.
