We started with a simple idea: the things you use most often should be the best things you own.
This led us to invent.
Opal has been working on new things that may surprise even you.
So much has changed in technology, and so much of technology is stuck in the lab. Opal is building a series of new devices, that give consumers exciting new abilities.
It's more than cameras
Focus:
Work at the intersection of ux and hardware to bring our devices to life with low-level code in power and latency-constrained environments.
- 2-6 years of experience in firmware development
- Partner closely with hardware and design teams to create seamless user experiences.
- Integrate wireless connectivity (Bluetooth, BLE, Wi-Fi, GSM) for latency-constrained real-time multimedia applications.
- Orchestrate power management for low-power and battery-constrained devices.
- Develop manufacturing test frameworks and field debugging tools that ensure quality at scale.
- Fluent in C/C++ for RTOS and bare-metal environments, Python for tooling, and the art of hardware debugging.
- Participate in cross-functional design reviews.
- Design over-the-air firmware update systems that are robust and simple to deploy.
- Ship consumer products that are a joy to use.
