Informacje o stanowisku

WithSecure protects businesses all over the world from modern threats. We do this through a co-security approach born from first-hand knowledge that no one can solve every cyber security problem alone. Every single day, our diverse, growing team fights against online extortion, threats to national infrastructure, the unlawful spread of sensitive information, and everything in between. The best part about working for WithSecure is our people! We are a community of dedicated and passionate professionals that take workplace happiness seriously.

Our teams have efficient and flexible ways of working, they self-organize and lead their own work to fulfil their goals. You are expected to do the same. However, whenever you need help, a second opinion or consultancy, seniors, experts, and hackers are always available for you.

We are looking for a Full Stack Developer with knowledge of the NodeJS ecosystem and a passion to learn.
