How we work
Open source, community-driven, and open to newcomers
Open source
Much of what we build is released openly, so other people can build on it. The code is transparent and auditable with no vendor lock-in; a wide community tests its security, ownership costs less, and the software always stays yours.
Community-driven
Our teams work in defined roles, alongside a global community of developers. More review means fewer defects, faster innovation and solutions that grow with what users really need.
Growing talent
We keep a route into the software industry open for juniors and career-changers. Real projects alongside experienced engineers bring talent to the surface and make our team stronger every day.
