Senior Backend Engineer

Backend Engineer | NRW Our client is seeking a backend engineer to help build the real-time infrastructure behind an AI-driven conversation intelligence product. The team is small, senior, and focused on a problem most backend engineers rarely encounter: systems where a few hundred milliseconds of delay changes the outcome. You'd be working on the services that stream live audio, coordinate transcription and language models in real time, and generate in-the-moment guidance while a call is still happening - where speed and uptime aren't secondary concerns but the actual product. The role: → Architect and maintain the real-time service layer and REST API that power the platform. → Coordinate a multi-agent processing pipeline spanning external AI and transcription services, working to strict latency requirements. → Design and iterate on the database structure supporting meeting data, transcripts, and generated insights. → Take responsibility for system reliability, monitoring, and security across infrastructure hosted entirely within the EU under GDPR. → Develop CRM integrations that support pre-call preparation and automatic logging of call outcomes afterward. → Node.js, PHP, and relational databases, hosted on cloud infrastructure. What you'll need: → Solid backend experience with Node.js and/or PHP/Laravel, and relational databases. → Experience with real-time systems, queues, and API design under latency constraints. → A security and privacy mindset, treating sensitive data with care by default.
