Perks & Benefits

We’re a young, ambitious company that aims to make usability testing accessible to any business. What started as a side project has now grown into a small but mighty startup backed by Earnest Capital.

So, let’s discuss why this is a great job.

You will work with amazing people.
We expect exceptional work. You will be joining a small team of A players and you will be expected to perform as an A player yourself. We are good at what we do and we love to get results.

You will have freedom and autonomy.
It’s up to you to figure out how to approach and solve a problem. No one is going to give you exact instructions or make you do it their way. With freedom comes a ton of ownership and responsibility. We believe when you control your destiny, you’re more invested in your work. And we can’t imagine working any other way.

You will make a difference.
You’ll get to see the direct impact of your work and the value created. Not only do we help small businesses improve user experience, delight users, and increase conversions, but our platform also enables thousands of people to earn money online through flexible work.

This job is results-oriented. You will be responsible for working in sprints and achieving goals. When and where you choose to work is completely up to you. Provided that you produce work that is exceptional and delivered on time, you can work whenever you want.

You will work remotely.
We are fully remote and have been since day one. You can live anywhere in the world, so long as you have a good internet connection and are available for weekly calls. Generally, it is easier to schedule and coordinate with people who live in North American or European timezones but exceptional candidates from all areas will be considered.

Sometimes we have retreats.
When it’s possible, we get together in person for 1-2 week sprints to get shit done while having a good time.
