Integrations Manager

Primer is the world's first unified payment infrastructure, founded by former leaders of Braintree and PayPal. We unify fragmented payment and finance systems into a single, intelligent platform, automating the entire payments lifecycle from acceptance and orchestration to reconciliation, FX, and financial operations. Trusted by leading merchants worldwide, we give finance, payments, and engineering teams the tools to move faster, reduce complexity, and unlock growth.

Our open, modular platform connects to 150+ services across the payments ecosystem, while our expanding CFO product suite brings unified reconciliation, FX management, and financial visibility across markets and currencies. Backed by Accel, Balderton, ICONIQ, and Tencent, we're setting a new standard for how the world moves money.

A Primer payment is worth so much more than a regular payment! In the Partners team we build a foundation of seamless, scalable, and reliable payments - across any provider, method, or market. We’re looking for an Integrations Manager to own and elevate the experience our partners and merchants have when integrating with Primer. This role sits at the intersection of Product, Partnerships, GTM and Engineering. You’ll act as a trusted technical partner and project owner, ensuring integrations are smooth, well-supported, and continuously improving — with a strong focus on quality rather than volume.

• Owning the end-to-end experience of partner integrations, from onboarding through to ongoing support.
• Scoping, triaging and coordinating technical and product-related requests from partners and internal teams.
• Working closely with the Partnerships team to support onboarding, enablement, and how Primer is presented and sold.
• Ensuring partners complete all required technical, operational, and compliance processes during onboarding.
• Acting as a technical point of contact for our partners and merchants, helping them navigate Primer’s platform and APIs.
• Creating and maintaining clear feedback loops between our Partners, Product, Engineering and other teams.
• Identifying opportunities to improve and scale integration processes, including automation and smarter tooling.
• Continuously improving the quality of the partner experience, informed by feedback and NPS insights.

• Experience in a partner-facing technical role (e.g. Integrations, Solutions Engineering, Technical PM, Product Ops).
• Strong communication skills, with the ability to explain technical concepts clearly to different audiences.
• Solid technical foundations, including experience working with APIs, SaaS platforms, and modern tech stacks.
• Confidence reading and understanding technical documentation and identifying gaps or friction points.
• A collaborative approach to working across Product, Engineering, Partnerships, and all other teams.
• A systems-thinking mindset, with an interest in automation, AI, and scalable ways of working.
• Experience in B2B SaaS environments (payments experience is a plus, but not essential).

• You enjoy working in an office-setting, we are remote-first and always will be!
• You are not comfortable with shifting context and navigating ambiguity.
• You don’t enjoy testing your code, we have no testers or QA’s here at Primer.

• 30 minute call with a Talent Partner.
• 60 minute Team Interview.
• Take home task, followed by a 1 hour presentation.
• 60 minute Primer Values interview.

We’ve been recognised as a top global employer, #1 in FinTech for ‘flexibility’! We’re building a culture where people can come and do their best work and enjoy it. We want our people to be proud of the impact that they have at Primer, and of the work that they are doing. You will be working with a team of people who are mission-driven, smart, and reflective, and who are invested in building exceptional products and delivering success for our merchants (and we also know how to have fun along the way).

We work remotely. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships with each other through great remote working practices and thoughtfully designed face-to-face time together. Our heads-together time comes in the form of workstations, our annual company retreat, and co-working space access worldwide.

Finally, let’s go ahead and say it. The work that we do is challenging. Startups are a challenge, building category defining products is a challenge. You should be prepared for a challenge at Primer. But, there’s a big difference between a challenge and a struggle. The key difference is that the right challenge comes with the right support structures, an acceptance that not everything always goes to plan, a collaborative environment, and a great team around you. It’s never a challenge that you will face alone.

• We are fully remote and globally distributed; and have been since day one.
• Competitive share options.
• Uncapped holiday, with 25 days minimum to be taken.
• Co-working space access.
• Workations & Company Retreat.
• The best equipment for your role.
• £500 towards your home office setup.
• Generous learning budget.
• Private Medical Insurance.
• A broad set of additional perks and benefits (depending on location).
