Which team will you be joining?
A Primer payment is worth so much more than a regular payment!
Reporting to an Engineering Manager, you’ll join a team of backend, frontend and mobile engineers all working together.
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.

In-depth understanding of the entire development process (design, development and deployment)

Knowledge of building developer frameworks and workflows, allowing both customers and third-parties to integrate as seamlessly as possible

Experience in Python is advantageous (it’s what we use!) but we have had success hiring engineers of any technical background and understand that people can adapt

Highly motivated self-starter who values autonomy and getting things done

Excellent verbal and written communication skills

Payments knowledge, always looking for ways to optimise our merchant developer experience

Your job is to refine and converge toward these expert-defined patterns.


What Youâll Do

rebuild reasoning/validation logic
optimize async performance
refine metadata â parameter mapping
implement override/preference logic
deliver a clean FastAPI backend


Skills Needed

Python
FastAPI
LLM structured outputs
systems logic
async/latency optimization
