Co-Lead Developer

Job Description

AxCrypt is one of the world’s most popular file encryption solutions, and consists of applications for Windows, Mac, iOS and Android along with a high performance web server infrastructure as well as several support applications. All in C#, a lot is open source under GPL and we also have automated procedures in place for localization, builds and deploys.

In this role, you will be charged with taking AxCrypt to the next level, designing and developing architecture and code as well as leading the Indian team.

To be successful, we think you need to be a meticulously careful security-minded developer with primarily a back-end focus, but front-end experience and skills are meriting and useful. You have most likely been a professional developer for 7-10 years or more. A better than average understanding of encryption is required, but expert skills are not required to start with. We do expect you to become an expert though. You need to be fluent in spoken and written English, and preferably in Swedish as well.

Your most important personal characteristic is probably an ability to write and test code that just works. Every time, all the time, under heavy load. You must also be a fast learner. We don’t expect you to know everything from start, but you need to learn quickly mostly by reading code and scripts and existing configuration.

The AxCrypt technologies include a wide range of C#/.NET software and scripts in various languages, including many support tools that tie the continuous integration and installer building together, as well as tools to manage financial reporting from payment providers handling complex EU accounting rules and currency conversions.
