FUNCTION: Engineering

We're looking for a Senior Software Engineer (Backend) to join our Fraud engineering team. This is a chance to help build a fraud prevention capability from an early stage, at a company moving money across fiat, crypto and card rails at global scale.

You'll design and build the backend systems that detect and prevent fraud across the whole customer journey: onboarding, login and account activity, payments and card transactions. That means bringing device, behavioural and transaction signals together, powering real-time risk decisions, and giving our Fraud Operations team the data and tools they need to act quickly. Over time, this capability will also protect the businesses that build on BVNK.

You'll work closely with Fraud Operations, Financial Crime, Data, Product and other engineering teams. We work in small, autonomous squads that own their problem space. We value strong opinions, simple solutions and moving fast in a sustainable way.

Key Areas of Responsibilities:

- Fraud platform development: Design, build and maintain secure, scalable backend services and APIs that power fraud detection, risk decisioning and controls.
