Compliance-as-Code & Observability:
- Collaborate with legal and product teams to translate complex global privacy laws (e.g., Germany's GDPR, South Korea's PIPA, UAE's PDPL) into concrete engineering logic.

- Partner with the DevOps Engineer to create comprehensive logging, monitoring, and analytics systems (e.g., using Prometheus, Grafana, OpenTelemetry) to provide deep visibility into platform health, security events, and business KPIs.

Description
We are seeking a deeply technical and security-minded Senior Backend Engineer to join our newly-founded, high-impact AI joint venture. Backed by five of the world's leading telecommunications giants, our mission is to restore trust in global voice communication. We are building a new category of network-native B2C security, moving from reactive in-call analysis to proactive pre-call verification that stops fraud before it starts. This is not a typical backend role; you will be the Stability & Monetization Owner, responsible for two of the most critical pillars of our platform: our monetization engine and our Zero Trust security architecture. You will build systems that protect our users' most sensitive data while navigating complex global compliance laws. Additionally, you will build the metering and entitlements engine that powers our entire freemium business model. This position offers a unique opportunity to create a globally scalable, highly secure, and compliant platform from the ground up. If you believe that security and privacy are non-negotiable product features and you are excited by the challenge of building the commercial and trust-based foundation of a new product category, this role is for you. This is a permanent position with hybrid working—two days a week in the central London office and the rest working from home. The salary is dependent on experience, with a guide between £110k-£140k basic package.
