Senior Backend Engineer - Monetization (Hiring Immediately) in London

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.

You will 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.
• 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 behavior, and system health.
• 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.

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 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.

Feeld is an independent, experimental and fully remote organisation reshaping the dialogue on dating and sexuality. We have a naturally agile and fluid culture. The whole team is fully remote, which means you work where and when helps you perform at your best. We believe in creating a safe work environment through humanity, fluidity, safety, transparency and progressiveness. Because we are a fully remote team, it’s especially important that we create an environment where our colleagues feel included and connected as humans.

Diversity, equity, inclusion and belonging at Feeld:

Feeld promotes open-mindedness, inclusion, diversity and kindness, both in the world and among our own workforce. We encourage and welcome applications from people with a history of marginalisation, whether because of race, gender expression or identity, sexual orientation, neurodivergence, national origin, disability (seen or unseen) or any confluence of intersectional identities.
