Responsibilities

Identifying and prioritising the right problems to solve, focusing on meaningful customer outcomes and making smart trade-offs to maximise impact with limited time and resources.
Owning features end-to-end, from early discovery and technical input through design, implementation, testing, and release.
Building and evolving core product capabilities, with an immediate impact on the reliability, scalability, and usability of our platform.
Iterating quickly and pragmatically, using your judgement and experience to balance speed, quality, and long-term maintainability.
Shaping technical direction in a small team, contributing to architectural decisions and helping define how we build and ship product.
Collaborating closely across the business, setting a high bar for communication through clear documentation, thoughtful proposals, and well-structured code.
Championing strong engineering practices, continuously improving how we work and supporting teammates through code reviews, pairing, and design discussions.

About you

Have hands-on experience building and shipping production software, using languages and frameworks such as Go, Python, or Ruby on Rails.
Enjoy working in small, high-trust teams, collaborating closely with other engineers and giving clear, constructive feedback to move work forward.
Take a product-first approach to engineering, partnering with Product to understand customer needs and prioritising outcomes and impact over purely technical perfection.
Are comfortable operating with ambiguity, contributing to early-stage thinking, helping shape solutions, and refining ideas as you learn more.
Thrive in iterative environments, sharing work early (even when it’s not “done”), gathering feedback, and adapting quickly based on input.
Balance speed with quality, making pragmatic decisions around technical debt, testing, and documentation to ship valuable features without over-engineering.
Care about building maintainable systems, and are thoughtful about how today’s trade-offs affect the product and team over time.

Nice to have

Experience designing or working with APIs, especially where data integrity, versioning, and backwards compatibility really matter.
Exposure to data pipelines or data-heavy systems, particularly where data quality, validation, or traceability are important (experience with regulated or sensitive data is a bonus, but not required).
Experience working in a remote-first team, comfortable collaborating asynchronously and communicating clearly across time zones.

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.
