Software Engineer - Growth

We’re hiring a Product Minded Software Engineer for the Growth team: a cross-functional team of engineers, Product Owner, designer and business owners focused on Journey 1 - from onboarding through to a customer’s first arrears point. Growth owns the customer and commercial journey end to end, plus the single-writer services behind it.

You’ll work close to the product and the business, not just the codebase. That means shaping problems, building the solution, measuring whether it moved the metric, and owning the feature in production. The team’s north star is growing the amount of good balances, with drivers including onboarding funnel conversion, utilisation, app reliability and onboarding fraud / ID-failure rates.

This is a hands-on product engineering role. You’ll build customer-facing journeys across app, web and backend services, improve onboarding and engagement, and help the team make better product decisions through technical options, fast delivery and strong operational ownership.

TECH STACK

- Backend: Node.js / TypeScript on AWS — serverless services using Lambda, API Gateway, DynamoDB, S3, SNS, SQS, EventBridge and Kinesis, alongside containerised workloads where needed

- Frontend: React Native / Expo / React / Next.js

- Infrastructure: Terraform, GitHub Actions CI/CD, Docker

- Observability: Datadog, Grafana, Prometheus, Loki

• Work as a product engineer in Growth: understand the customer problem, shape the technical approach with Product and Design, and ship changes that improve Journey 1 outcomes
• Build and improve onboarding, acquisition funnel conversion, login, account management, card management, personal details and other customer-facing Growth features
• Own features in production: monitor health, respond to issues, maintain runbooks, and make sure we know about degraded journeys before the business or customers tell us
• Take first-pass ownership of bugs and support queries that surface in Journey 1, fixing what is ours and handing over with diagnosis when the root cause sits with another service owner
• Contribute across the services Growth owns, including onboarding, biometrics, APR, CLM, legal service, alert service, app and website front end
• When Growth work extends a service owned by another team, build it under that team’s contributor rules rather than handing it off
• Use data and product context to make better engineering choices: understand conversion, utilisation, reliability and fraud / ID-failure drivers, and connect technical work to measurable outcomes
• Write clean, tested, maintainable code and documentation so the team can move quickly without losing quality
• Collaborate closely with engineers, Product, Design, QA and business owners, bringing technical options early rather than waiting for fully formed tickets
