Senior Python Engineer · Real-Time Signal Processing & Full-Stack (R&D) | Freelance via Shakers

We're looking for a senior engineer to own an R&D platform that captures real-time acoustic signals from a multi-sensor array, processes them on the fly, and turns them into interactive feedback for live research experiments. Hardware integration, real-time signal processing and web app, all in one role.

What you'll own:

• The Python processing pipeline: real-time acquisition, signal processing, detection algorithms
• Hardware ↔ software integration: sensor arrays, DAQ, real-time data streams
• The full stack: Node.js / TypeScript API, Next.js frontend, MQTT messaging, Docker

What we need:

• 5+ years building production software
• Strong Python, comfortable with data and signal processing
• Backend and real-time systems (WebSockets, MQTT)
