  • November 2016 - 2 Client & Server Developers - CLOSED




    CodeSealer A/S delivers advanced security applications for mitigating MITB-based attacks against online banking, gaming and retail platforms. The main product, WSF, consists of a native JavaScript client and a custom server written in Go. We are currently seeking two full-time senior software developers to aid in further design and development of our solution.

    We are a small startup company with a tightly-knit development team. At CodeSealer you will get the opportunity to directly influence the direction of the company and the product, with a high degree of individual freedom and responsibility.




    We use an agile approach to development with emphasis placed on testing and correctness. Our workflow is based on Git, Stash and Jenkins CI. The WSF application is an in-browser sandbox and crypto engine, managing all JavaScript code execution in the browser, verifying the browser environment and providing encrypted and authenticated network communication beyond the provisions of TLS. The security of the product is based on advanced cryptography and automatic code obfuscation.




    The right candidate has 3+ years of professional experience, preferably including:

    - Native JavaScript development for a variety of browser environments

    - Server programming in Go

    - Network programming using network sockets, HTTP(S), TLS and AJAX

    - Experience using version control (such as Git) and continuous testing and integration

    You are expected to be a team-player with the ability to work in a structured manner. We frequently make use of new technologies and platforms so you should be able to adapt quickly. We place a lot of emphasis on making the workplace a positive and friendly environment, even during crunch-time before a deadline.




    We offer a competitive salary with a pension scheme and health insurance, 5 weeks of vacation and 5 days of paid leave.
