We've reinvented the fundamental principles of automation to democratize technology, optimize buildings, and reduce the world's carbon footprint. We are a team of technologists, engineers, and creatives dedicated to making a sustainable impact through real-world solutions.
We are looking for team members who have a passion for technology and want to work on cutting-edge problems with real-world solutions. Our culture is built on bringing together the most talented engineers, thinkers, and creatives-backed by the world's leading investors-working together to make the future a reality.
About the Role
This is a career-defining opportunity to play a crucial role in a hyper-scale AI company that is transforming the future of autonomous systems, energy, and the built environment.
As an Embedded Systems Engineer at PassiveLogic, you will co-lead development of our suite of building controller hardware products, from zero to manufacture. You'll collaborate closely with the electrical, mechanical, industrial design, and verification/validation (V&V) teams to deliver robust, innovative solutions. This role demands a disciplined, independent leader with stellar embedded software skills, a systems-level mindset and the ability to self-teach and solve tough problems. You will contribute to shaping the product vision, drive its execution, and ensure it meets our standards for quality and efficiency.
What you'll do
Develop embedded systems: End to end development, from architecture design to high-volume production, of firmware and software for our embedded platforms, that is robust, functional, power-efficient, and feature-rich.
Test and validate embedded systems: Design and implement HIL/SIL testing frameworks to validate robust, fail-safe code before V&V handoff. Collaborate with electrical, mechanical and industrial design teams to maintain product vision alignment.
Collaborate on Feature Development: Work with platform architects, product management, and product design teams to architect and implement new features from initial concept to productization.
Ensure Hardware-Firmware Platform Robustness: Use a structured and efficient approach to bug management. Perform hands-on system debugging to integrate hardware and software seamlessly.
Prepare and maintain technical documentation: Maintain meticulous engineering and code documentation and communicate progress/design intent.
What you'll bring
