Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Own the end-to-end measurement of voice AI audio quality across devices, networks, and models. Design automated test infrastructure and lead audio data collection efforts for model training and evaluation.
Requires 5+ years of experience in audio quality or DSP engineering with a strong background in telecommunication standards and Python. A Bachelor's degree in Electrical or Computer Engineering is required, with a Master's or PhD preferred.
Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.
We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.
To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.
Voice is the primary interface between Hark's AI and the people who use it, so audio quality is a product requirement, not an afterthought. We are hiring an Audio Quality and Data Engineer to own the end-to-end measurement of how our voice AI sounds, listens, and behaves — from the microphone array on the device, through the speech enhancement front end, across telephony and network paths, and into the conversational model itself.
In this role, you will design test methodologies and metrics, build the automated test infrastructure that runs them, and lead the audio data collection efforts that feed both evaluation and model training. Your work will directly shape how customers experience our consumer AI devices and voice AI agents, and the quality bar you define will become the bar the rest of the company ships against.
The US base salary range for this full-time position is between $250,000 - $300,000 annually.
The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
Building the Intelligence Behind the Next Generation of Products.
Hark Labs is a GenAI and product innovation studio helping startups and enterprises harness the power of artificial intelligence. We design smarter products, automate complex workflows, and turn data into dynamic intelligence — bridging the gap between cutting-edge AI research and real-world business impact.
