Hybrid working: All Starling colleagues spend a minimum of 10 days per month in the office with flexibility to work the rest from home. The Opportunity: We are looking for a Technical Growth & MarTech Lead to bridge the gap between our Growth Marketing, Data Science, and Engineering squads. Operating in a highly regulated and privacy-first financial environment, you will serve as the technical architect of our growth engine.

You will build highly secure server-to-server conversion tracking pipelines, manage our app-first MarTech stack, and use custom scripting to safely integrate AI workflows into our BI and analytics environments. What You'll Do: 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.

Data Infrastructure & BI Alignment: Partner directly with Starling’s Data Engineering and BI teams. Design clean event schemas, optimise attribution pipelines, and integrate our secure data warehouses with marketing platforms—ensuring absolutely zero leakage of sensitive PII. AI Tooling & Secure Automation: Utilise Python and JavaScript to automate marketing operations and interact with LLM APIs. Build custom scripts that empower the marketing team to leverage AI for creative scaling, optimisation, and analytics, strictly within our security and compliance guardrails.
