OUR MISSION:

ButterflyMX is on a mission to empower people to open and manage doors & gates from a smartphone. Our products are installed in more than 15,000+ multifamily, commercial, gated communities, and student-housing properties worldwide, including properties developed, owned, and managed by the most trusted names in real estate. Our features are designed for developers, owners, property managers, and tenants and our products lower operating costs and improve tenant satisfaction.

OUR CULTURE & VALUES:

Fantastic people are the key to our success. As a distributed, primarily remote workforce, we’re looking for more intelligent, passionate, collaborative, and down-to-earth individuals to join our growing team We’re driven by a shared commitment to excellence and innovation, grounded in our core values: We delight our customers, We take ownership, We are a community of collaborators, We speak up, We think big and do small, and We are tenacious.
We are looking for a stellar Electrical Engineer to design, develop and support the electronic aspects of our current and future hardware products. You will be working collaboratively as part of a high-performance hardware development team on-site at our Hardware Engineering lab in Southern California, providing knowledge, expertise and design engineering of electrical, electronic and communications solutions. This role will report to the SVP Hardware and be responsible for all electrical design, electronics development and communication aspects of our products.

REQUIREMENTS
