Diversity & inclusion

A recent study shows that one in every 10 tech workers in Spain are women. Only 8% of all contracts in 2019 with people with disabilities were in technology and science. Meanwhile, 30% of LGTBIQ people in Spain don't come out in the workplace for fear of discrimination.

This is neither the world we want to live in nor the workplace we’re building.

Mitiga Solutions is committed to creating a diverse environment and is proud to be an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, colour, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status. In fact, we strongly encourage applicants from minority groups to apply.

We believe diversity isn’t a checkbox but a strategic strength. We actively seek out different perspectives, backgrounds, and experiences because they make us better.

Inclusion means everyone has a seat at the table and a voice that’s heard. It’s not just policy, it’s how we build, hire, and lead.
