Hybrid working: All Starling colleagues spend a minimum of 10 days per month in the office with flexibility to work the rest from home.
- Fintech AdTech & Conversion Engineering: Build, audit, and maintain robust, privacy-compliant conversion tracking architectures across our app and web ecosystems. Deep focus on Mobile Measurement Partners (MMPs like AppsFlyer/Adjust), SKAdNetwork, Conversion API integrations, Google Ads Server-Side GTM, and secure offline conversion imports.

Turn complex growth ambitions into clear, secure technical specifications for our backend and app engineers, while helping marketing teams understand data integrity, technical constraints, and platform logic. You must act as a bridge.

- Experience operating within secure cloud environments (AWS).
Behaviours & Competencies:
- Security & Privacy-First Mindset: Operating in a highly regulated financial environment.
