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 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 cataloguing and managing parts online.

This role

The Strategic Account Manager owns post-sale success for parts suppliers on the Partly Network and reports directly to the GM of Europe. This role is responsible for ensuring suppliers achieve measurable commercial and operational value from Partly’s infrastructure. It sits at the intersection of supplier relationships, product delivery, and engineering execution, and requires deep ownership of supplier issues in a fast-moving, evolving product environment.

What will you do

• Own strategic supplier relationships: Develop trusted, long-term partnerships with parts suppliers, acting as the primary post-sale owner and point of accountability. Ensure strong adoption, retention, and long-term value realisation from Partly.
• Own supplier issues end-to-end: Take full ownership of supplier issues from initial report through root cause analysis, resolution, and follow-up. Work closely with product and engineering teams to drive issues to ground rather than simply escalating them.
• Translate supplier problems into product execution: Convert supplier pain points and operational challenges into clear, actionable product requirements. Produce written problem statements, reproduction steps, and expected outcomes to enable fast, effective execution by engineering.
• Lead onboarding and ongoing success: Own the end-to-end post-sale journey including onboarding, implementation coordination, and ongoing success management. Ensure suppliers are set up to operate successfully on Partly infrastructure from day one.
• Drive measurable business outcomes: Develop a deep understanding of each supplier’s KPIs, revenue drivers, and operational constraints. Through regular reviews, identify and execute opportunities where Partly can unlock incremental value, efficiency, or growth.
• Operate with urgency in an evolving environment: Work effectively in a fast-moving, ambiguous environment where product capabilities and processes are still developing. Maintain momentum, prioritise effectively, and drive progress despite incomplete information.
• Build scalable success foundations: Design and evolve lightweight processes, tooling, and documentation that allow supplier success to scale without compromising accountability or responsiveness.

Your skills

• Senior stakeholder management: Comfortable working with senior leaders at complex organisations. Able to manage expectations, navigate ambiguity, and maintain trust during periods of change or product instability.
• Strong communicator across technical and commercial audiences: Able to engage credibly with engineers while clearly articulating technical issues and solutions in commercial terms to supplier stakeholders.
• Experience working with technical or infrastructure products: Comfortable operating close to technical systems and workflows. Able to understand platform behaviour, diagnose issues, and validate solutions in collaboration with engineering teams.
• Strong prioritisation and ownership mindset: Demonstrates clear ownership, bias to action, and sound judgment. Able to balance supplier advocacy with internal priorities and drive alignment across teams.
• Commercial and operational acumen: Understands how supplier businesses operate and how technology impacts revenue, cost, and efficiency. Able to articulate ROI and map Partly’s infrastructure to supplier objectives.

Bonus

Experience in the automotive aftermarket, parts distribution, or supply-chain ecosystems. Familiarity with cataloguing, fitment, or global parts standards is advantageous.
