  • We invest in your growth with a dedicated development budget and plenty of opportunities to advance in your role.

  • We take hiring seriously with a strong focus on keeping a high bar when interviewing (equally important is that we hire decent people, who are passionate about their craft and helping us achieve our shared mission).

  • While we're not quite fully-remote, we are committed to being a flexible employer, as we understand you don't have to be in the office to do your best work.

We live a culture of empowerment, trust (that we hire the best people and get out of their way) and openness (there's a greater advantage in sharing information than keeping it to ourselves).

Our values

  • Learn and grow. We aim high to shape our future. We give and request honest feedback knowing that we develop together. Progression over Perfection.

  • Team first. We make it easy for others. We value our differences and are open to others' opinions. We win and celebrate together! Team over Egos.

  • Own the outcome. Whether we win or we lose, we stand together. We are proactive and get the job done. Outcome over Process.

  • Tell the story. We always start with the why. We share knowledge to empower others. Transparency over Complexity.

Upvest is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees
