Job

Role

Who you are

You work incredibly hard, have high agency and take pride in what you do
You (Love using) use AI to design, code, debug, and ship (way) faster (if you think AI is a nuisance, this is not for you)
Solid experience building backend APIs and systems in C#/.NET
Strong grasp of enterprise architecture patterns (DDD, CQRS, microservices)

Desirable

You like the idea of becoming a start-up Founder one day
Background in payments & fintech
This job is primarily back-end, but if you can go into SDKs + Front-end UI it would be a big plus (React)
You can take a Lovable app and make it enterprise grade, you can build an API by hand but know how AI can accelerate it 10x

What the job involves

Opportunity to join at the earliest stage and build the world's first instant payments network
You’ll work directly with the founder to design, build, and launch our core platform
You will be working at the bleeding edge of AI development within an enterprise environment
Hands-on, high-impact role: you'll write code daily, influence key architectural decisions, and ship fast using modern tools and AI
Modern backend from scratch in C#/.NET 8 with a clean, event-driven architecture
Help architect a scalable system using CQRS, Event Sourcing, DDD, microservices
Own key components in AWS: Lambda, SQS, SNS, DynamoDB, PostgreSQL, API Gateway

Application process

Our take

One of the foundational problems of cross-border payments is the 40-year-old infrastructure on which it runs, making it slow, opaque and expensive. 3 Degrees is building a solution described as an “open payments superhighway” that will help fintechs, corporations, and banks accelerate their cross-border payments.

3 Degrees will incorporate the use of modern tech stacks, instant payments and APIs to help build an instant, affordable and transparent global standard for international payments. Currently still in stealth mode, its founder has an extensive background at some of the world's largest and most successful fintechs, so it’ll be exciting to see how 3 Degrees’ solution fares upon release.
