Safer together

At a glance 

About CrowdSecurity : Our mission is to deter security breach, through an Internet scale, real time, security network. This network is powered by thousands of users, sharing with one another the aggression they blocked with our software. By coupling this local behavior analysis and sharing its findings within our community, we create a giant hacker interferometer, a large scale reputation system, that will deter the vast majority of technical hacks. 

You’re part of the core team designing crowdsec software architecture and taking care of its implementation and maintenance. You have some experience with open source software and golang and design&implementation of serverless architectures. You know when to take a step back to get the big picture and decide the next moves. You love to work in a team, and you are remote-friendly. 

You have a real background and kick for security: ideally, you have spent some time on the offensive side of security (pentest, audits etc.), and you integrate security early in your designs.

If you’re able to put yourself in user’s shoes to create accessible and easy-to-use software, but love as well to contribute to the design of a serverless/k8s architecture to handle hyper-growth and achieve high velocity in development, we’re looking for you 🙂 

By the way, we’re not selling shoes on the internet, we’re trying to make internet a safer place for everyone by creating and distributing open-source software. Love for at least open-source and possibly security is strongly advised! 

Playful enough? Want to learn stuff and challenge things? Bored by what job market is willing to offer? Want to join an A team? Come & apply.
