We proudly ship Secure Group’s products for Android to thousands of users around the world.  
The heart of the organization is our team of Android Developers. They consistently push the boundaries of encrypted communications in order to maximize Secure Group's apps and deliver the most secure mobile solutions.


Our responsibilities step mainly on managing the complete software lifecycle – from analyzing requirements to creating prototypes, transforming wireframes into high-quality code, and implementing new features.
The developers are in charge of handling the entire software lifecycle, from requirements analysis through prototype creation, wireframe conversion to high-quality code, and feature implementation.


Ensure the top quality of our solutions by developing and executing unit tests, troubleshooting issues, removing impediments, and improving the overall performance of Secure OS. You will be working along-side other engineers and developers working on different layers of the infrastructure. Therefore, commitment to collaborative problem solving, sophisticated design, and creating quality products is essential.
Growing within this framework entails cooperating with other developers and producing high-quality apps.


We envision each of our employees as stakeholders, so you will be responsible for driving the collaboration with other teammates and agile teams, act as a subject-matter expert to less experienced Software Engineers, and add user value to the solution.

In order to progress in our development path and Level Up or Step Up, our Android Developers must:</br>
* Meet the criteria of the Level & Step Chart for the [[Individual_Contributors|Individual Contributors Path]]
* Meet the criteria of the Level & Step Chart for the [[Individual_Contributors|Individual Contributors Path]]

* Meet the [[Android_Development#KAI_of_the_framework|KAI]] grade of the framework related to each level
* Demonstrate proficiency in [[Secure Group Knowledge]]
* Demonstrate proficiency in [[Secure Group Knowledge]]
== Level A ==
The Level A path is destined for employees who still do not possess the skills or proficiency in the whole set of criteria required of Individual Contributors. If during the hiring process we detected that you had the potential to quickly become Level 1, we made you an offer for Level A so you can expect to be provided with coaching, structured tasks with technical challenges, and the opportunity to learn and grow so you can be part of the Management Model as an Individual Contributor.
=== Golden Rules ===
To Level Up to become part of the Individual Contributor's Path, the Level A employees must:
* Meet the criteria of the [[Individual Contributors]] Level & Step Grid in one year.
* Demonstrate proficiency in the [[Knowledge_Management#Knowledge_Grade_Description|KAI]] of the Android Development framework according to the levels.
