Job Description
My client is building a new digital banking platform inside one of the world’s largest financial institutions, following the successful launch of a major consumer banking product.
The team operates more like a fintech than a traditional bank, building cloud-native products from the ground up with Java/Kotlin, modern architecture and a strong product engineering culture.
What you’ll do:
- Build scalable backend services in Kotlin
- Design resilient systems with no single points of failure
- Use domain modelling to shape new banking products
- Build secure, highly available APIs and distributed systems
- Own problems from design through to production
Why this team?
- Greenfield environment with genuine influence over architecture
- Fully cloud-native with a multi-cloud strategy
- Product-focused engineering rather than feature-ticket delivery
- Opportunity to work on products used by real customers at significant scale
We should speak if you have:
- Strong backend engineering experience with Java or Kotlin
- Strong software design and domain modelling skills
- Experience building reliable, highly available production systems
