You'll help build customer journeys that enable clients to discover investment opportunities, compare savings products, search across financial instruments and complete account opening and transfer journeys.
What You'll Be Doing
- Design, develop and maintain backend services powering the Discover platform.
- Build scalable APIs and integrations with internal and external systems.
- Develop AWS serverless applications using modern engineering practices.
- Contribute to platform scalability, resilience, observability and performance.
- Work across the full stack where required, collaborating closely with frontend engineers.
- Take ownership of features and issues from design through to production.
- Support CI/CD pipelines and deployment processes.
- Drive engineering improvements, automation and operational excellence.
- Participate in architecture discussions, code reviews and technical design sessions.
- Collaborate closely with Product, Platform and Engineering teams to deliver customer value.
