As a Senior Fullstack Engineer, you will develop and improve the Feeld mobile app and its backend systems, ensuring performance, reliability, and security. You will work on features, collaborate across teams, and address technical debt in a remote environment.

Lead mixed-method user research across discovery and iterative testing, combining qualitative studies, surveys, and product analytics to generate actionable insights that shape product strategy, roadmap prioritisation, and research operations (recruitment, panels, vendors) in a fully remote app-based environment.

Build, optimize and maintain mobile monetization flows (paywalls, subscriptions, in‑app purchases). Implement scalable state management, integrate billing SDKs and analytics, reduce crashes and friction, and support experimentation and regional pricing for sustainable revenue growth.

Own and operate scalable, secure backend systems powering monetisation: subscriptions, billing, entitlements, pricing, promotions, and in-app purchases. Improve reliability, observability, experimentation, and analytics to minimise revenue-impacting incidents and enable data-driven product decisions.
