Senior Full Stack Engineer

About the job

At Bliss Aesthetics, we’re bringing one of the world’s fastest-growing industries into the digital age.

The global medical aesthetics market is on track to surpass $200B in the next decade, yet the patient journey is still unclear, fragmented, and stressful. Choosing a procedure, understanding outcomes, finding the right provider, and securing financing shouldn’t feel overwhelming - but today, it often does.

So we built Bliss.

Bliss is a consumer-focused digital health platform that uses AI to match with board-certified providers, move seamlessly from discovery to procedure and help people visualize realistic cosmetic outcomes.

We’re a well-funded Seed-stage startup, backed by top-tier investors, with a growing team split between Israel and the U.S.
