Backend Engineer

An Introduction to Primer

The 21st century has witnessed remarkable expansion within the payments ecosystem with the introduction of new payment services, growth in cross-border commerce, and the development of multi-payment processor payment strategies.

The bottom line is that payment is no longer just another step in the purchasing funnel but a strategic asset that can drive business growth and innovation.

Enter Primer – the world’s first unified payment infrastructure, empowering businesses worldwide to unleash their payment potential. By choosing our platform, merchants can take control over their payment stack, create unique commerce experiences, accelerate their roadmap and increase payment success.

Primer’s enterprise-grade infrastructure, frameworks, and tooling allow merchants to unify their disparate payment solutions and services to build optimised payment flows tailored to their unique business needs with no code or additional complexity. We strive to make something complex incredibly simple and intuitive.

Our success so far has been reflected in the trust placed in us by category leaders such as Printify, NewLook, Voi, and Dabble, who are using Primer to transform their payments into a growth lever. Moreover, the world’s top investors, including Accel, Balderton, Iconiq, and Tencent, have also invested in Primer’s vision to rebuild payments and commerce from the ground up.

Join us in shaping the future of payments and commerce. Let’s pave the way for a world where businesses can fully realise their payment potential.

What’s the culture like at Primer?

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.
