Life at Threadflip

We are a lean, fast-paced, and agile startup, so there is a lot of room for impact: in our code, our product, our culture -- you name it. You may pitch an idea and then implement it a few days later, or spec out a feature in the morning and push your code to production in the evening. We're committed to building a simple, slick and social user experience with Threadflip -- come build it with us!


Threadflip wants you to be healthy. We provide comprehensive health, dental, and vision insurance. We also offer flexible PTO to be used at your discretion: you decide when you need a break. Got a dog? No problem. Our amazing diggs are dog friendly so we welcome your four legged friends with open arms (and paws!). We offer delicious and nutritious catered lunches and a never ending snack supply to keep you fueled throughout the day. We’ll also make sure you are decked out with the cutting edge technology that you need to get your best work done. With regularly planned team events and outings and sponsorship to industry-related events, there is also lots to do outside of the office!
