Which team will you be joining?

As it stands, we currently have multiple teams hiring for backend engineers. Our talent team will be able to provide you with more information on what these teams cover at the interview stage.

Reporting to an Engineering Manager, you’ll join a team of backend, full-stack, and frontend engineers all working together alongside our Product team.

The team adopts a ‘you build it, you own it’ approach, working with infrastructure, doing their own testing and QA.

Our tech stack includes:
Python, Typescript, React, AWS, Kubernetes and Terraform, amongst lots of other things.

🔍 What will you be doing?

• Designing and implementing core backend services for high performance, complex distributed systems
• Driving and using modern development practices such as BDD and TDD would be highly beneficial
• Creating clear, modern, well tested code
• Collaborating across teams in a product-driven environment
• Taking ownership of key technology decisions, building for scale and optimising for output
• Conducting code reviews and continuously look at ways of improving our ways of working
• Creating detailed internal documentation for the projects you work on

👀 What We’d Love To See

• Experience coding Python in modern, complex technical environments
• Experience with testing frameworks and a good approach to writing testable, maintainable code.
• Understanding of the entire development process (design, development and deployment)
• Highly motivated self-starter who values autonomy and getting things done
• Excellent verbal and written communication skills
• Experience working in a fast-paced environment.
• You will need to be based in:
  Poland, Portugal, Hungary, Romania or South Africa.
• 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
• 45 minute interview with an Engineering Manager
• 60 minute final stage values-alignment interview

What’s the culture like at Primer?

We’ve been recognised as a top global employer, #1 in Fin Tech for ‘flexibility’!

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 , 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.
