Senior Product Engineer, Hardware

About the role

SageOx is building AI‑augmented hardware devices, starting with the Ox Dot, a small audio‑enabled device that serves as a physical embodiment of their AI‑driven platform. As the first dedicated hardware engineer, you will own the full stack from firmware to cloud services, ensuring the device is stable, fast, safe and ready for mass production.

Key responsibilities

• Drive firmware and hardware development for the Ox Dot and future devices, including boot, memory, audio pipeline and connectivity.
• Build and maintain a 24×7 automated hardware test lab with continuous, unattended testing and behavior‑driven development scenarios.
• Design and implement OTA update pipelines, staged rollouts, health‑gated updates and A/B rollbacks for millions of devices.
• Develop cloud services, APIs and user‑facing applications that interact with the device and its digital twin.
• Work directly with suppliers on supply‑chain, enclosure design and accessories.

Required profile

• Hands‑on experience building and shipping embedded hardware products.
• Strong problem‑solving mindset with ability to set up automated testing and debug hardware regressions quickly.
• Comfort with fast‑changing product direction and ability to adapt to new hardware platforms.

Required skills

• Embedded firmware development (bootloaders, audio pipelines, connectivity).
• Hardware test automation and continuous integration for physical devices.
• OTA update mechanisms and fleet management.
• Cloud service development and API design.
• Experience with behavior‑driven development (BDD) for hardware.
