About the Role
Backend Engineer
The Opportunity
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.
