Senior Hardware Engineer

About Density

Density’s mission is to measure and improve our footprint on the world.

We help companies understand how their workplaces are used. We do that by observing behavior in the office through our highly accurate and always anonymous sensors. In other words: where are people actually spending their time?

We translate that data into actionable, opinionated insights that help companies increase the financial and experiential performance of any workplace.

Today, we work with companies from Fortune 500s to high-growth innovators in technology, financial services and healthcare, occupying more than a billion square feet worldwide.

And we’re in it for the long game: what if we knew more, created better spaces, and could build cities that worked and felt better? That’s where you come in.

• Design and develop complex analog and digital circuits, including schematic capture and PCB layout.
• Conduct simulations and analysis to validate circuit designs and ensure compliance with specifications.
• Work with manufacturing partners to develop and refine prototypes and production units.
• Develop and execute test plans to verify hardware functionality, reliability, and performance.
• Propose and implement innovative design solutions to enhance product performance and user experience.

The ideal candidate will have:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• Minimum of 5-7 years of experience in hardware design engineering, with a focus on system integration in consumer electronics.
• Proficiency in electronic design automation (EDA) tools such as Altium Designer, Cadence Allegro, or similar.
• Strong knowledge of circuit design principles, signal integrity, power management, and electromagnetic compatibility (EMC).
• Demonstrated ability to troubleshoot and debug complex hardware issues.
• Experience with embedded systems, microcontrollers, and communication protocols (e.g., I2C, SPI, UART).
• Experience modifying embedded software and debugging low-level SW/FW [-> Hardware issues
• Excellent project management, organizational, and communication skills.
• Ability to work effectively in a collaborative, in-person, cross-functional team environment.

We offer:

• Excellent benefits including medical, dental, vision, mental and reproductive health, 401K, equity, Flex Fridays, Remote Friendly, unlimited and mandatory PTO and more.
• A company full of fun, smart, talented and legitimately kind teammates. Our culture powers everything we do and we work hard to nurture it by bringing on the right humans.
• A team hailing from innovators like Apple, LinkedIn, Stripe, Meraki, Flexport, WeWork, NASA & beyond.
