Senior Backend Monetization Engineer in London

At Feeld, we are creating a world where everyone is more intimately connected to each other and themselves. We are building an inclusive, human‑centred product and are looking for a Senior Backend Monetization Engineer to become part of our remote team and our mission to elevate the human experience of sexuality and relationships.

You will be responsible for designing, building, and operating scalable, secure backend systems that power the company’s revenue‑generating experiences to ensure monetisation flows are reliable, compliant, observable, and performant at scale.

To be right for this role, you should have extensive experience in Backend development with some specific experience with in‑app purchases, pricing, and other revenue‑related services.

What you will do:

• Drive outcomes, not just features. You'll own the health of our monetisation funnel and be responsible for the reliability and performance of the systems that keep Feeld sustainable.
• Design and maintain scalable backend systems that support integrations related to subscriptions, billing, entitlements, pricing logic, and promotional mechanics as the user base grows.
• Ensure high reliability and correctness of monetisation flows, minimising revenue‑impacting incidents and reducing time‑to‑detection and resolution.
• Enable faster experimentation by supporting feature flags, testing, and analytics instrumentation across monetisation systems.
• In partnership with the Data team, build and maintain analytics and reporting capabilities that provide insight into revenue performance, user behaviour, and system health.

How you will grow:

• Deepen your expertise in designing and operating revenue‑critical systems at scale.
• Develop advanced skills in system observability, monitoring, and incident response for high‑throughput financial workloads.
• Expand your knowledge of analytics infrastructure, experimentation frameworks, and data‑driven product development.
• Improve your collaborating skills with non‑technical partners by translating complex technical concepts into clear business insights.

About you:

• You have experience designing, building, and maintaining backend services that handle high‑throughput, business‑critical workloads such as payments, subscriptions, or financial systems.
• You are comfortable working with databases, APIs, and ensuring data integrity and security in production environments.
• You are skilled at communicating technical concepts clearly to non‑technical cross‑functional partners.
• You approach problems with curiosity and systems thinking, balancing technical excellence with business impact and user experience.

Bonus points:

• You have experience building or maintaining subscription platforms, billing systems, or working directly with payment providers like Adapty, Stripe, RevenueCat, or Apple/Google in‑app purchase APIs.
• You have worked with analytics pipelines, experimentation frameworks, or feature flagging systems to support data‑driven product decisions.
• You have mentored other engineers or led technical initiatives that improved system reliability, performance, or developer experience.
• You have experience with mobile backend integration or supporting cross‑platform monetisation flows across iOS, Android, and web.
