Their mission is to simplify financial and transactional processes with clean, elegant engineering.

They're hiring a senior C# back-end engineer to help lead feature development across some of their most strategically important product areas.

Designing back-end services from scratch - no boilerplate or cookie-cutter code
Building out secure, high-availability APIs
Collaborating with other engineers and product leads on solution design
Writing clean, scalable C# code
Leading by example: mentoring others, improving processes, shaping engineering standards

You'll also get protected weekly time to focus on your own learning and development - whether that's tech research, upskilling, or experimenting with new tools.

What you'll need:

Strong hands-on experience in C#/.NET Core
Experience with distributed & event-driven systems
A solid understanding of message queues (RabbitMQ, SQS/SNS etc.)
Strong grasp of data and performance concerns at scale
A thoughtful, product-focused engineering mindset
