Which team will you be joining?

A Primer payment is worth so much more than a regular payment.

In the Orchestration team we build the engine that powers intelligent, seamless, and reliable payments — across any provider, method, or market. We own the full orchestration layer: routing decisions, fallback logic, and the smart infrastructure that makes every payment perform at its best.

This team covers everything from checkout and payment processing through to tokenization, authentication, fallback logic, developer tooling, and workflows.

As a Backend Engineer L3 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 Orchestration and contribute to systems that handle real payment volume at scale.

What will you be doing?

- 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...
