Senior Frontend Developer

About Merchery

Merchery is born from the simple observation that corporate gifts and promotional products are most of the time low quality. This billion $ market is shady, and often made of products people throw away after two weeks. Our vision at Merchery is to offer beautiful, useful and carefully sourced products that people actually want. We are an early stage startup launched in April 2020, and are now looking for a new family member.

Joining the Tech team as a Senior Frontend Developer...

• is an opportunity to take a leading role in shaping the user-facing side of our platform and to build interfaces that elevate the experience of our customers. You will work closely with our design, backend, and product teams to turn bold ideas into exceptional digital experiences. At Merchery, we value quality, creativity, and curiosity—and we want someone who brings all three.
