Sr. Frontend Developer (Western Europe

Kencko | Posted 7-09-2021

Lisboa (Arquitetura / Design)

We\'re seeking a collaborative, mission-aligned Sr.Frontend Developer to join the team!

Our Mission

We make it easy for everyone to build healthy habits and eat more fruit and vegetables by creating innovative products that are highly nutritious, sustainable and delicious.

How We Do It

We transform fresh, organic fruits and veggies into handy single-serving instant smoothies. Each one contains about 80 calories, and gives the same nutritional benefits as 2.5 cups of fresh produce.

Almost half of the world’s fresh fruits and vegetables are thrown away uneaten. Our flash-freeze, slow-dry process cuts waste by putting produce on standby until our members are ready to enjoy it. We also lighten our footprint by using compostable packaging and offsetting all emissions from shipping!
