Growth-Focused Software Engineer for Onboarding Journeys

Onmo; City Of London; On-site; GBP 90,000 - 130,000; Full time

Job summary

Onmo is hiring a product-minded Software Engineer for the Growth team: a cross‑functional unit focused on Journey 1—from onboarding to the first arrears point. You’ll shape problems, own features in production, and collaborate with Product, Design and business owners to improve the customer journey.

You’ll work across app, web and backend services using Node.js/TypeScript on AWS, with React Native for mobile and Infrastructure as Code (Terraform).

Qualifications

• Proven experience as a product‑minded backend, frontend or full‑stack engineer building and running production systems.
• Strong Node.js / TypeScript experience, ideally with AWS and event‑driven or serverless architectures.
• Experience building customer‑facing web or app features, preferably with React Native / Expo / React / Next.js or similar modern frontend frameworks.
• Good understanding of Infrastructure as code with Terraform; CI/CD as a habit.
• A track record of using testing, monitoring, documentation and code review to raise quality around you.
• You write clean, tested, maintainable code and leave systems more understandable than you found them.

Responsibilities

• 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
