Frontend, Backend, iOS and Android. Mobile apps crash over 1 billion times a day - let's do something about it!

Crashlytics is the most powerful and lightweight crash reporting and analysis service for iOS and Android. If you're interested in the intersection of great UX, scalable systems, the mobile internet, and big data analytics we want to talk to you!

We're an early stage startup looking for truly talented engineers with a passion for clean code and great products. Our team is fast, smart and independent -- with previous startup success.

We're small and growing rapidly, so it's important to us to have a great company culture to support that growth. We offer all of the usual startup perks: snacks in the kitchen, flexible work schedule, top-of-the-line gear (Macbook Air, Thunderbolt display, iPad/Android Tablet), etc. Additionally, we feel strongly that it's the culture created by shared values that really makes Crashlytics a great place to work.

Here's a brief look at a few of the things we value:
We focus on the modern web - We don't support IE6, so you'll never have to worry about it! We love feedback - you’ll be able to connect directly with customers who are using what you’re building and use their input to make the product better. We’re self-directed - We trust you to manage your own schedule, vacation, etc. without complex policies or forms to fill out. We ship - we're huge fans of…

I appreciate and welcome this requirement from Apple.

Some time ago I built something I call “Network Blackhole”.

The project intercepts HTTP traffic from applications that I installed in either my MacBook or iPhone. An excellent example of this is Crashlytics [1], Segment [2], and Sentry [3], which are among a list of popular web services that many developers use to report bugs and crashes in their software, and the famous Google Analytics, which I hope I don’t need to explain what it is used for.

With the help of Little Snitch [4] a popular network monitor for macOS, I detect when an app tries to connect to one of these services, or similar. Then I execute a tool written in Go like so: “blackhole example.com” which does the following:

1. Inserts domain into /etc/hosts

2. Create an HTTP web server (in Go)

3. Adds a match-all endpoint to the server

4. Creates an SSL certificate with mkcert [5]

5. Creates an Nginx virtual-host for the server

6. ???

7. Profit

In the end, and after 1-2 minutes, I have all the traffic to that domain gracefully redirected to a black hole, reducing the amount of data that I leak to 3rd-party websites.

However, don’t get me wrong, I understand the purpose of these services, I haven’t said they are evil or anything like that. I would probably use them myself if I had to, but I certainly would add an alert to ask for explicit consent from the user to send this information to a service that I won’t even have control over. If one of them…

We use a combination of Appsee, Crashlytics, and Firebase. Crashlytics for super in depth crash reporting. Appsee to see how users interact with the app via user session recordings (you don't get that with other analytics tools). Firebase for everything else.
