What the job involves
- We are seeking a highly skilled and motivated Electrical Engineer specializing in sensors and RF (Radio Frequency) circuits to join our team. The ideal candidate will be responsible for designing, developing, and optimizing electronic systems that integrate sensor technologies in low power embedded platforms. This role requires strong technical expertise, innovative problem-solving, and the ability to collaborate across multidisciplinary teams
- This role is an excellent opportunity for an engineer passionate about pushing the boundaries of sensor and RF circuit technology optimizing the built environment. If you thrive on innovation and enjoy tackling complex challenges, we encourage you to apply
- Design, prototype, and test circuits including RF, low power MCUs and peripherals for sensor applications
- Develop sensor interface electronics for applications such as IoT use cases
- Optimize designs for performance, power efficiency, and cost
- Perform circuit-level simulations using tools such as SPICE, HFSS, or similar
- Model and simulate RF and sensor performance to predict and mitigate potential issues
- Design schematic diagrams and guide PCB layout using tools like Altium Designer, Eagle, or KiCad
- Build and test circuit prototypes to verify functionality and performance
- Debug and troubleshoot circuits to address design and manufacturing issues. Document and maintain testing results for compliance and reporting
- Conduct lab testing and validation of RF circuits and sensor systems
- Utilize network analyzers, spectrum analyzers, and oscilloscopes to measure and optimize RF and antenna performance
- Communicate technical results and trade-offs effectively to stakeholders. Participate in design reviews to ensure project alignment and quality
- Stay up to date with advancements in RF and novel sensor technologies, researching emerging trends and proposing innovative solutions for future products
- Create comprehensive design documentation, including schematics, layouts, and test reports
- Ensure designs meet industry standards and regulatory requirements (e.g., FCC, CE, UL etc.)
Our take
Butlr, an Artificial Intelligence of Things (AIoT), leverages a wireless heat sensor and AI which detects human presence and movement to gauge how space is being used.
The tech is targeted predominantly towards enterprise clients who want to better understand how their commercial and office space is functioning, as well as for fall detection in senior care. Crucially, Butlr’s sensor does not capture any personally identifiable information – which should help its popularity with employees and occupants.
Though it’s not the only company to make inroads in the workspace and spatial analytics niche, with the likes of Density and VergeSense also growing, it's encouraging that Butlr has been able to land big clients in the form of Georgia Pacific and Carrier.
Having completed three major fundraises in consecutive years, Butlr’s headcount is growing steadily on both product and commercial fronts.

Company values
- Innovation – From our MIT and Berkeley roots to our recognition as a Technology Pioneer by the World Economic Forum, we pride ourselves on seeking innovative solutions to thorny problems. Innovation is often synonymous with simplicity. We thus strive to simplify, to approach hard problems via first principles, to not be afraid to challenge convention.
- Get stuff done – We are thinkers and dreamers but, above all, we are builders. Innovation is just theory if nothing gets done. We work at pace and are not afraid to hustle to deliver quality work on time and on scope. We are driven by the end result and we celebrate the realized.
- Low egos – We wouldn’t be the team we are today if we let our egos get in the way. We grow when our teammates grow and blossom next to us. It's why we feel safe in mindfully giving and receiving feedback. We collaborate with one another towards our shared mission. We give up our legos and always play the ball, not the person.
- Ownership & Accountability – We believe in acting and thinking like owners, proactively owning our work and not hesitating to pitch in elsewhere when the team needs it. We also believe in being held accountable for our work, and using any shortfalls as learning opportunities to improve ourselves.
- Excellence – Excellence lies beyond simply executing a task in the optimal way. Having good judgment when making compromises, noticing where there's opportunity to improve, and always striving for the best is what we believe constitutes excellence—and everyday we show up with this in mind.
- Adaptability – We believe that the only constant is change and that we need to constantly be evolving ourselves accordingly. We strive to adopt a growth mindset, to always be learning, to push ourselves out of our comfort zone, and to handle change and ambiguity in stride.
