About SpyFu
SpyFu is a self-funded, profitable, and growing SaaS company. We started the company, in Scottsdale, AZ – and most of our employees live here. But, we’re fully remote and our common hours are Mountain Time. We still have an IRL culture; we get together for lunch and parties – play ping pong, drink beer, etc. It’s optional, but if you’re nearby it’s cool to hang out. If you get the job, you’d be the 20th full-time employee. So, you’ll have the opportunity to make a big impact.
We offer:
- We have the best possible Health and Dental benefits. Walk into the Mayo Clinic like you own the place.
- A 401k with 4% match
- Flexible work hours. Just get things done, be available for meetings, and fix stuff when it breaks. Otherwise, do whatever works best for you.
- Bring your cat to work. Or your dog. Or your kids – whatever, because you’re at your own house chillin’ and getting stuff done with the people and things you love. Like a boss.
SpyFu is an Equal Opportunity employer. We’re LGBTQ+ and specifically trans-friendly/competent. We value diversity, inclusiveness, and empowerment. This isn’t corporate speak – this is who we are as people. We do everything we can to create a safe and respectful workplace, and we’ll always have your back.
