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.

We have several engineering roles open:
* Senior Software Engineer, iOS - $176,000 to $207,500 - https://www.fullstory.com/careers/jobs/ab3f8ecb-ee1f-4431-a0...
* Senior Software Engineer, Application Experience - $160,000 to $190,000 - https://www.fullstory.com/careers/jobs/1a014b19-d805-4547-9a...

Tech stack includes Typescript & React for the front-end; Go (Golang) running on Google Cloud (GCP) w/ Kubernetes (K8s/GKE), BigTable, BigQuery, Solr, and more for the back-end; Java, Objective-C, and Rust for mobile; and smaller amounts of other languages including Swift, Kotlin, Dart, Python, and Ruby where they make sense.
Note that for the iOS role, we're not building apps. It's about taking things apart, seeing what makes them tick, and figuring out how to extract the data we need without negatively impacting the app experience. (Or using any private APIs!) It's part reverse engineering, part systems programming, and part library development.
In addition to the listed pay ranges, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, and more. I take about 5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)
You also get a 5-week sabbatical after 5 years of employment - I just took mine at the end of last year, and it was fantastic.
To apply, please submit your info on the website. If you have questions, feel free to reply here or email nathan@[company website].com.

We make a Configure-Price-Quote SaaS for complex product portfolios. For example, one customer is Tetra Pak, that sells machines that build packaging (milk, juice, etc). These machines are like a two-story building with many variations, every aspect has to be well-defined and validated before it's ordered.
In our solution products can be modeled in detail with constraints, and during a sale options are chosen and validated, often visualized parametrically, pricing is done, and a quote is prepared. All based on the well-defined model.
It's a 30-year old company that started as a research startup, grew organically, and has a stable customer base. After a recent acquisition it's aiming to grow, therefore many positions are open. I started working here just a year ago, but I can say the work environment is healthy and relaxed, lots of competent people and everyone I interacted with so far have been very nice and professional.
