Software Engineer III, Backend - Account Exprerience

📋 Description

• • As a Backend Engineer, you will work within a small, high-calibre team of engineers who own their work end to end.
• • You'll report into the Engineering Manager for Account Experience and contribute to systems that power the merchant platform at scale.
• • Take full ownership of backend features from scoping through to production, keeping the team informed on progress, risks, and blockers without being chased.
• • Design and deliver backend services that handle real payment volume, with a strong focus on reliability, performance, and correctness at scale.
• • Contribute to architecture discussions, bring proposals to the engineering council, and advocate for clear service contracts and simple, maintainable system design.
• • Monitor the production impact of your own work, identify issues early, and drive incidents to resolution when they arise.
• • Write code that your peers consider high quality: production-ready, well-considered on error paths, and built with the next engineer in mind.
• • Actively contribute to Primer's engineering standards, raise concerns when you see gaps, and help the team hold a consistent bar.
• • Collaborate with engineers across the Account Experience team on scoping sessions, code reviews, and technical decisions that shape how the system evolves.
• • Solid backend engineering experience, with the ability to take ambiguous requirements and deliver working, production-ready software with minimal direction.
• • Strong grasp of distributed systems fundamentals: you understand why things fail in production and you build accordingly.
• • Comfortable working with REST APIs and the patterns that make services reliable, observable, and easy to reason about.
• • Experience owning work end to end not just writing code but thinking about monitoring, rollout, and what happens after deployment.
• • The confidence to contribute to architecture discussions, ask the right questions, and push back when a design decision doesn't make sense.
• • Experience in a payments, fintech, or infrastructure context is a plus, though depth of engineering matters more than the specific industry.
• • Primer is remote-first. There is no office to fall back on when you want context, direction, or a sense of how things are going. You need to be good at operating without those signals.
• • We do not over-engineer our processes. If something is unclear, you're expected to resolve that ambiguity yourself rather than wait for someone to remove it.
• • The Orchestration codebase is not simple. You will inherit technical complexity and will be expected to deal with it thoughtfully, not just work around it.
• • 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
• • 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.
