Company

hirify.global is an artificial intelligence company developing multimodal intelligence and next-generation hardware for natural interaction through speech, text, vision, and persistent memory.

What you will do

• Bring up audio on new Android hardware, including codecs, microphones, speakers, routing, and low-level platform integration.
• Design and manage playback, capture, voice, and always-on listening use cases on SoC platforms.
• Integrate and tune audio paths across Audio HAL, AudioFlinger, Audio Policy Manager, TinyALSA/ALSA, and SoC audio frameworks.
• Debug end-to-end audio issues using platform logs, kernel traces, DSP traces, and application-level symptoms.
• Support audio-driven AI inference workloads such as wake word detection, ASR, and speech enhancement within latency, power, and memory budgets.
• Collaborate with hardware, acoustics, AI, and product teams from prototype through production.

Requirements

• 3+ years of professional firmware or embedded audio development experience, preferably with consumer products shipped at scale.
• Proficiency in C/C++ in resource-constrained, real-time environments.
• Experience with Android audio architecture, including Audio HAL, AudioFlinger, Audio Policy Manager, and TinyALSA/ALSA.
• Hands-on experience with audio tooling and frameworks.
• Ability to work across kernel drivers, DSP firmware, HAL, and framework layers and debug issues spanning the full audio stack.
• Experience with board bring-up alongside hardware engineers and ability to read schematics for audio subsystems.

Nice to have

• Knowledge of dynamic range control, echo cancellation, noise suppression, beamforming, and related audio-processing algorithms.
• DSP optimization experience with fixed-point development, SIMD, and VLIW.
• Experience tuning audio quality across acoustic conditions.
• Experience deploying machine learning models on embedded platforms, especially audio models running on DSP or NPU.
• Experience shipping voice-first or far-field audio products.

Culture & Benefits

• Work on multimodal AI systems and next-generation AI hardware designed as a unified interface.
• Hands-on work close to silicon with direct impact on consumer audio experiences.
• Full-time position with a US annual base salary range of $120,000–$300,000.
• Total compensation may include additional components and benefits depending on the role.
