Job description

An Introduction to Primer

Primer is the unified infrastructure for global payments. We give finance and payments teams the visibility and control to reduce complexity, improve performance, and capture more revenue - all from a single platform.

Backed by Sofina, Peak XV Partners, ICONIQ, Tencent, Accel, and Balderton, we're building the payments layer the world's best companies rely on.

What will you be doing?

• Working closely with our growing sales team to identify merchant pain points and consulting with those merchants on the value of Primer to address them
• Providing technical expertise to the sales team to partner with them in business development
• Translating business requirements into technical solutions, and translating complex technical concepts into simple language
• Driving forward client engagements via discovery sessions, solution design workshops, product demos, developer Q&A, and more
• Guiding merchants from initial conversations in pre-sales through to successful go-live and ramp-up, ensuring a smooth end-to-end integration process
• Acting as a project owner during complex merchant integrations, aligning internal and external stakeholders, creating implementation plans, and mitigating risks proactively
• Collaborating with our Product team, using your market learning to identify feature enhancements and new features to better serve our merchants

What we’d love to see

• Previous experience in a merchant-facing role with a complex API product, ideally in payments
• Comfortable implementing frontend SDKs in web or mobile environments and advising developers on integration best practices
• Confidence and ease in leading discovery sessions, joining presentations at C-level, and working with technical counterparts at some of the largest merchants
• Deep interest or knowledge about tech, understanding, explaining, and designing complex technical solutions is second nature to you
• Project management skills, you’re organised, proactive, and can lead integrations involving multiple teams and dependencies
• Creativity and improvisational skills, rarely are two merchants alike, and you don’t always have days to prepare
• Excellent communication and presentation skills, you make the complicated sound simple and interact effectively with both technical and non-technical stakeholders
• A collaborative approach, you work well with clients, partners, and internal teams (Product, Engineering, Sales)
• Drive and motivation, we’re growing fast and want you to grow with us!
• Experience working in a fast-paced and scaling environment

You may not like it here if:

• 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

A typical interview process

• An initial intro call with a Talent Partner
• An interview with the Hiring Manager
• Challenge Stage - Contextualised to the role
• A final, values-alignment interview

What's the culture like at Primer?

We're building a culture where people can do their best work and be proud of the impact they have. You'll be working with people who are mission-driven, smart, and reflective, and who are genuinely invested in building exceptional products and delivering success for our merchants.

We work remotely, and have done since day one. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships through great remote working practices and thoughtfully designed face-to-face time, including workations, our annual company retreat, and access to co-working spaces across most major cities. The work is challenging. Scaleups are a challenge, and building category-defining products is a challenge. But there's a meaningful difference between a challenge and a struggle. At Primer, the right challenge comes with the right support: strong onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face alone.

Our benefits

• We are fully remote and globally distributed; and have been since day one
• Competitive share options
• Flexible holiday, with 25 days minimum to be taken
• Co-working space access across major cities
• 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)
