Hiring Process

Send us your application at career@stagewise.io – and please be creative!

We value outstanding and creative applications far more than polished CVs that look oddly tailored to the role. Don't worry about having the "perfect" resume — we care about who you are, not how well you can format a document.

Tell us your story, a product you genuinely enjoy using (and why), why you're the perfect fit, and what makes you unique. We want our team to consist of extraordinary people, and your application should reflect that.

Afterward, we'll kick things off with a short 15-minute video call, followed by a 30-minute meeting at our office. After a trial day where you can meet the team and learn more about the product, we'll get started if both sides feel it's a great fit.
