Mechanical Engineering at Synapse

Synapse’s Mechanical Engineering team helps design cool, innovative products for the consumer and industrial spaces by partnering with a multidisciplinary team of software, electrical, quality assurance, and new product introduction engineers. Whether designing a wearable device that can withstand harsh environments, devising a lighting solution to support stringent user experience requirements within tightly integrated electronics, or developing a complex thermal and fluids system in an aggressive form factor, Synapse’s MEs bring an attitude of fun, flexibility, and fearlessness to an ever-changing array of exciting design challenges.

Synapse engineers collaborate directly with clients as well as each other, so they are equally comfortable communicating as they are contemplating. They have the tenacity to see a product through from concept to mass production, and they don’t mind changing hats for the good of the project. Synapse engineers are always learning—and teaching: the opportunity to be a listener and a leader exists for engineers at every level. They are willing to understand the client’s objectives as well as its organizational environment while delighting in exceeding the customer’s expectations. And Synapse engineers approach each other with the eagerness to learn, sense of humor, friendly attitude, and mutual respect that make working at Synapse as enjoyable as it is rewarding.


About Synapse’s San Francisco Office

Synapse’s San Francisco site, which will accommodate the office’s planned growth in the years ahead, offers proximity to transit as well as the amenities of the SoMa neighborhood. Here, the growing group of about thirty Synapsters balances focus with fun. Wednesday Lunch provides a catered meal to the entire office, as well as a time for employees to celebrate successes and navigate shared challenges. Thursday Active is the office’s opportunity to lift their noses from the grindstone and take part in a range of activities—from bike trips and runs, to museum visits and sporting events, to barbecues and poker tournaments.
