Senior Product Manager

Note: Partly is headquartered in the UK, with a Product and Engineering base in Christchurch, and an early presence in San Francisco . If you are not based in Christchurch, we will fly you to HQ for 2 weeks for onboarding, as well as 1 week per quarter for our “Season Openers” (we pay for your travel and accommodation). If you are relocating to Christchurch from NZ or from overseas, we can also assist with relocation costs. 🚀 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 toward a sustainable future where anyone can fix anything. Founded by ex-Rocket Lab engineers, we utilise bleeding-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 cataloguing and managing parts online. Our investors in Blackbird Ventures (Canva, CultureAmp etc.), Square Peg, Octopus Ventures, Icehouse, Peter Beck (Rocket Lab), Akshay Kothari (Notion Co-Founder) and Dylan Field (Figma Co-Founder). We're continuing to build a world-class team and ensuring Partly is a place where people can do the best work of their lives. We're proud of the culture we've built at Partly, and our values are lived throughout every experience. Want to learn more about the problems we're solving and the culture we're building at Partly? Hear directly from our team here: https://shorturl.at/iAFUX 🖍️ This role This is a full-ownership product leadership role. You will own one or more of Partly's core products end-to-end - acting as a mini-Founder for your product(s), with full accountability for vision, Product–Market Fit, growth, and outcomes. Your focus is not just shipping features, but ensuring the product delivers durable customer and business value as Partly scales across markets and segments. You'll be operating at an inflection point. AI-assisted development and agents are compressing product discovery and delivery cycles. The best PMs we know are no longer waiting for engineering capacity to test an idea - they're building rapid prototypes themselves, deploying them, reading the signal, and deciding within days. We're looking for someone already working that way, or actively building toward it. 💻 What you'll do Own your product, end-to-end Define and evolve the product vision, strategy, and roadmap aligned with company direction. Continuously assess and improve Product–Market Fit across relevant markets and segments, including multi-sided platform and marketplace dynamics where applicable. Own key product and PLG metrics - activation, adoption, retention, expansion, NPS - and use them to steer all decisions. Lead go-to-market alignment for your product, including packaging, positioning, and rollout sequencing. Act as the single accountable owner - for successes, failures, and everything in between. Stay close to customers Maintain direct, regular contact with customers - calls, site visits, usage sessions. This is a core weekly activity, not an occasional input. Talk to buyers and users separately; understand where their needs align and where they conflict. Combine qualitative customer insight with quantitative usage and metric data. Read both and reconcile them. Translate what you learn directly into prioritisation and PMF assessment - and share it with the teams that need it. Build and ship, not just specify Prototype new product iterations yourself using AI-assisted development and LLM-assisted tooling - fast, disposable, real. We call this vibe coding; it is our default mode for product discovery. Treat the prototype as the hypothesis. Test with real customers before writing the spec. Run structured A/B tests and experiments where appropriate; use results to drive prioritisation. Work hands-on with data: define metrics, build dashboards, query logs, read the signals directly. Lead in the human loop Partner closely with engineering leads to balance discovery, delivery, and technical sustainability. Align GTM, marketing, operations, and support around product direction and trade-offs - including advance notice of what is shipping and what it means for customers. Communicate priorities and reasoning clearly - especially when the answer is no. Represent the customer's reality in every internal decision, not as a summary but as evidence. Lead in the agent loop Design and instrument feedback loops that let you learn from system behaviour alongside user behaviour. Define what "working" means for agentic or AI-driven features - in terms of evals, edge case handling, and observable outcomes. Think in systems: how does a decision here affect behaviour across the whole product loop? Raise the bar Contribute beyond your product boundary: cross-product coherence, shared principles, and the overall product craft at Partly. Help define what excellent product ownership looks like here as the team grows. 🥷 What you bring Non-negotiables 5+ years owning complex B2B software products end-to-end, with clear accountability for outcomes (not just delivery). Proven experience with product discovery, roadmapping, and outcome-oriented prioritisation in a fast-moving environment. You build rapid prototypes yourself - with AI-assisted tools, LLM-assisted development, or code - as a first instinct for testing ideas. You think in outcomes and can describe failures as clearly as wins. Strong analytical instinct: you define the metrics, build the view, read the data, and act on it - without waiting for a data team to hand it to you. Sufficient technical depth to work credibly with engineers and understand architectural trade-offs. Excellent judgment under ambiguity. You commit, you course-correct, you own the outcome. You make trade-offs explicitly and can articulate what you decided against and why. Strong signals we look for Experience in B2B SaaS, API products, marketplaces, or multi-sided platform businesses. Experience with AI-assisted product development or building AI-native product features. Comfort thinking in feedback loops, evals, or system-level instrumentation - not just user stories. 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 Experience in automotive, logistics, or supply chain domains. Experience scaling products across multiple geographies or customer segments. Experience with product-led growth (PLG) motions in a B2B context. You've built or operated products with meaningful agentic or automation components. Please note: if you don't have all the skills/experience listed above but believe you could be outstanding in this role, please still consider applying. Many folks often count themselves out. Please allow us to learn more about you and why you're exceptional! 🧭 How you'll think and operate We're not looking for framework experts or consensus-drivers. We're looking for someone who thinks like this: "I don't need to wait for the sprint - I built a test version this afternoon and three customers have already tried it." "The anomaly in the run log is more important than the feature request in the backlog right now." "Here's what the data shows. Here's what I think it means. Here's what I'm doing about it. Here's when I'll be wrong." "I own this. If it fails, that's on me. Let me tell you exactly how it failed and what I learned." Speed, ownership, and judgment are the baseline. What differentiates the best candidates is the ability to operate fluidly across both human systems and technical ones - and to shrink the distance between intent and outcome.
