Join an early-stage, venture-backed startup that solves a real-world problem in the B2B SaaS space. If you enjoy a flat leadership structure in companies where you can contribute to ideas, new technologies, and suggested improvements without going through several levels of managers, this role might be for you. If you like transparency and open communication in a company, if you like focusing on solving problems, instead of attending a million meetings, and if you can appreciate the benefits of being one of the very first recruits in a new startup, then we could be a great fit together!

Is a natural problem solver, who knows how to solve problems by automating their solutions.

Understands the role and impact that programming can have on the real world.

Next Steps:

Applying is easy. There are just four steps to our process. The first is completing the questions below. The second is a small at-home exercise. The third is an interview with our CTO. The fourth is an interview with our CEO. After the fourth step, the decision is made within 24 hours. The entire process takes about a week.

What's the URL of your website? If you don't have one, why not?

What's your coding history? When did you start, and what have you done between then and now?

What was your favorite job you had so far? What made it so great?

What do you want to do with the rest of your life, and how do you think working at an early-stage start-up is a step toward your long-term goals?

Have you dedicated any time to a side hustle/project? What was it about? Is it still active? What did that experience teach you?

Is the CV not your thing? That’s great, it isn’t ours either! Forward your responses to the questions and anything else you want to add to b2Mub3NweWxsYWNAbmF5aXRzaXJr. We're excited to hear from you!

After this:

We'll approach you with a simple take at-home test

Nothing more than 2-3 hours top, we appreciate your time and the goal is to use the test so we can have something more to talk about during our first interview

Then you'll have an interview with our CTO

Then an interview with our CEO

All your information will be kept confidential according to EEO guidelines.

We are a B2B SaaS company in stealth mode.
