Real-Time Backend Architect – Latency-Critical

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 5 years+ 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.
