An Introduction to Primer

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.

Which team will you be joining?

At Primer, Solutions Engineers are trusted technical advisors to some of the most forward-thinking companies shaping the future of commerce. We don’t just support merchants, we empower them to build smarter, faster, and with confidence on top of Primer’s unified payments infrastructure.

From day one, you’ll work closely with product, engineering, and commercial teams, translating complex needs into scalable solutions, guiding technical strategy, and ensuring every integration is rock-solid. Whether you’re unblocking a proof of concept or future-proofing an architecture, your focus is on making things possible.

This role is perfect for curious minds who thrive at the intersection of technology and impact. You’ll bring clarity to complexity, act as a critical voice in shaping product evolution, and make sure our merchants don’t just go live: they go further.

If you’re excited by meaningful challenges, collaborative problem-solving, and the chance to drive change at a global scale, we’d love to meet you.

Great communication & presentations skills - you can make the complicated sound simple and interact with stakeholders, technical and non-technical, alike
A collaborative approach - to efficiently work with clients, partners, and internally, with Product, Engineering, and Sales

Our 2025 Product Showcase

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.
