About Whispp
Whispp is an award-winning deep-tech startup in Leiden. Our on-device Voice Reconstruction AI turns whispered, affected, and noisy speech into a person's clear, natural voice - in under 100 ms, on-device, with full speaker identity preserved. We license the technology as an SDK to smartphone and PC OEMs, chipset vendors, and hearing-protection manufacturers, and we have active proof-of-concept programs with tier-1 partners.
The role
You are the technical bridge between our AI platform and the OEM partners who embed it. You own the hands-on work of getting our SDK running on customer hardware, from first scoping call through validated PoC, signed NRE, and production integration.

What you'll do
Integration and delivery - Integrate and validate the W2S SDK on customer devices, chipsets, and OS environments - Qualcomm Snapdragon, PC NPUs, emerging hearable platforms. - Own technical execution of PoC and NRE programs: hardware setup, milestones, KPI measurement, demos, and final scope documentation. - Find and fix integration blockers early - hardware quirks, OS audio pipeline incompatibilities, latency and performance gaps. - Keep demo hardware reliable and ready for customer meetings and trade shows.
Customer engagement - Act as the primary technical contact for OEM engineering teams during PoC, NRE, and validation. - Translate customer constraints - microphone configurations, NPU limits, audio pipeline architecture - into concrete...
