We are looking for smart, creative developers with a solid theoretical background. You should be able to look at a problem from the user's perspective, discuss abstract concepts with fellow developers, as well as produce an elegant implementation. Developers we have hired in the past mostly hold an exceptional master's degree in computer science or even a doctorate. At think-cell, we like flat hierarchies. You will work largely independently and will be responsible for the whole range of activities when implementing a new feature. We expect each of our developers to do architecture, design, implementation and bug fixing, rather than splitting these activities between several people. We thus minimize communication losses and put everyone in control of their own work. Your ideas are welcome, even if they mean that we have to change a lot of code to make things better. We have published several scientific articles in the areas of Artificial Intelligence and Computer Graphics and we will...

We trade financial instruments using a Java-based automated trading platform. We connect to external financial exchanges and counterparties over LAN using various protocols which pass through a normalization layer within our platform. We also do some trading with a third-party trading platform, which exposes a .NET API (we build C# apps). We have a variety of work available ranging from adding new features, QA/test coverage improvement and automation, debugging complex issues, etc. in both our Java platform and in our various C# apps. We place a high value on code and documentation quality, and cleanliness. We prefer to write and maintain as little code as possible. Initial work will not be highly performance/latency sensitive, but future work may be. Ideal candidate will be a server-side java and/or C# expert with API and networking experience. Prior work with FIX or trading-related API's such as Interactive Brokers, Lime, etc. is highly valued. Some basic familiarity with market...

We have a app that plays a video and once the video finished we want it to mark a internal calendar. We mark the calendar with a check mark once it shows that the video played for that day. Even if the video plays multiple times we only mark the calendar once for that day. We also need to send a reminder to use the app, There is a toggle switch and when the toggle switch is on it will remind them to use the app at 7am everyday. NOTE: if this requires Push notification then this will be removed from the deliverables. We can now use this app while in airplane mode. Some general clean up, removing video controls when the video plays, if they touch the screen the controls come back. Fixing the video so it starts in portrait mode. The app has no back end and is native to phone. Self contained.
