FusionAuth | Senior Security Engineer, others | Denver, CO, USA ONSITE (other positions are remote as) | Salaries listed on job req, but for the Security Engineer it is 140k-120k

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our app to petrichor

* a relatively mature product (the code base is over eight years old and we've found and fixed a lot of the sharp edges around core login use cases; however there are plenty more features to add)

* founder-led; the CEO is an engineer who still writes code

* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already

If you are passionate about technology and want to join a company moving the industry forward, FusionAuth might be a great fit for you. As mentioned, our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure.

We are profitable but raised a round in 2023 to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).

Technologies and standards that we use or implement: Modern Java, MySQL, PostgreSQL, Docker, Kubernetes, OAuth, SAML, OIDC.
