SENIOR C++ ENGINEER – REMOTE

We are seeking an experienced Audio Software Engineer to design, implement, and integrate real‑time DSP algorithms into the Windows audio stack, spanning DSP runtime environments, Windows Audio Processing Objects (APOs), and audio driver integration.

This role sits at the intersection of audio signal processing, Windows system software, and OEM / codec‑vendor integration, ensuring high‑quality, low‑latency, and certifiable audio solutions on Windows laptops and devices.

Responsibilities:

• Design, implement, and optimize real‑time audio DSP algorithms (EQ, dynamics, limiting, transducer protection, spatial processing).
• Ensure DSP code meets real‑time performance, latency, and CPU constraints.
• Design and implement Windows Audio Processing Objects (APOs) System Effects (SFX). Endpoint Effects (EFX)
• Integrate APOs with the Windows Audio Engine following Microsoft interface contracts and threading models.
• Work with OEM or codec‑vendor audio drivers

Skills:

• Strong C / C++ development experience
• Solid understanding of digital signal processing for audio
• Experience with real‑time, low‑latency systems
• Strong debugging skills (timing, threading, memory)
• Windows Audio Engine fundamentals
• Windows APO development
• WASAPI concepts
• Familiarity with audio driver stacks and codec integration

Nice to have:

• Experience with audio certification flows (HLK, WHQL)
• MATLAB / Simulink or DSP modeling tools
• Audio measurement tools and lab workflows
