About our software

Our focus is on business slides (as opposed to more artful, open-ended applications) because they offer great potential for automation of the layout tasks traditionally performed by PowerPoint users themselves. There are plenty of challenges, from a solid understanding of what makes a good layout, to algorithms that produce an aesthetically pleasing output fast enough for interactive slide design, to an intuitive and unobtrusive user interface that supports our original approach to slide layout, to solid technical solutions for automatic bug reporting and updates, to compatibility with third-party software on the computers of over a million users.

Here are some highlights of what we have done

Language

• Everything we do is C++. Even our customer portal is written in C++. There is some Assembler glue code where necessary, and our build scripts are written in Python, but other than that, think-cell is all about C++.
• We closely track the latest versions of our compilers, Visual C++ and Xcode, so we can always use the latest C++ standard features as soon as they become available.
• We fund the working group for programming languages of the German Institute for Standardization (DIN). Some of our employees are members of this committee and vote in the international standardization process ISO / IEC C++.
• We are also an official sponsor of the Standard C++ Foundation, which promotes international standards for C++. 

Library

• We use Boost throughout our code, e.g., Boost.Spirit for parsing.
• We have our own range library, in the same spirit as Boost.Range or Eric Niebler’s range-v3, but we go further, for example, by unifying internal and external iteration. We gave a talk about it, and most of the code is public.
• We develop our own cross-platform library to support macOS and Windows with a single code base. You can find our public library here.
• We have our own reference-counting and persistence libraries to save and restore whole object trees.
• We have an extensive bug-reporting infrastructure. Assertions and error checks stay in the release code, and our software automatically reports bugs to our server. The server analyzes the bug, categorizes it and files it in a database that all Developers can access. If an update fixes the bug, the user can download the update directly from a bug response web page.

Algorithms

• think-cell was founded on the idea of an algorithm for automatic slide layout, and we are still on an exciting journey towards that ambitious vision. You can see our most recent release in action!
• We developed a new algorithm for automatic point cloud labeling that allows labels to be positioned away from the actual points.
• We developed a new algorithm for automatic column chart labeling.
• We are working with John Forrest – author of the linear solver CLP – to make his simplex code faster for our kinds of problems.
• We developed many generic data structures that are not in C++ or Boost, such as partitions.
• Our software not only produces charts, it can also read them off print and digital images. For our chart recognition tool, we rely on OpenCV and the Leptonica Image Processing Library.

Reverse Engineering

• We do lots of reverse engineering with the disassembler IDA from Hex-Rays to achieve things that are not possible through the documented Microsoft Office API.
• We have probably written the best function-hooking engine out there. Each time our software starts, we patch the Microsoft Office executables in memory. Rather than hard-coding patch addresses, we search for small chunks of assembly code to protect against minor changes in the executables.

About this job

We're looking for bright, creative Developers with a solid theoretical background. Our team’s backgrounds range from 10+ years of commercial experience in various fields to fresh graduates in Computer Science, Physics, and Mathematics. A university degree or work experience with C++, in combination with a fresh and creative problem-solving approach, would be ideal for this role. We love working with talented people, whether you're a student, fresh graduate, or C++ expert, therefore our recruitment process is skills-based and consists of tasks related to the role.

You will mostly work independently and will be responsible for the whole range of tasks involved in implementing a new feature. You should be able to look at a problem from the user's perspective and discuss abstract concepts with fellow Developers. We expect each of our Developers to do architecture, design, implementation, customer feedback and bug fixing, rather than splitting these activities between several people. We thus put everyone in control of their own work.

At think-cell, there are no deadlines or scheduled meetings. A feature is ready to be released when you are convinced that you have implemented the best possible solution. Meetings take place as needed, and only the people actually involved in the topic are required to attend. At any time in the process, ideas, suggestions and criticism from anybody in the hierarchy are welcome and are seriously considered. We want to hear your ideas, 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 encourage you to do the same. We sponsor visits to conferences and have close relationships with universities and research institutes across the U.S. and Germany.

think-cell encourages a healthy work-life balance. We do not work at night or on weekends.

We pay very competitive salaries and offer our Developers EUR 130,000 annually after one year of employment. If necessary, we will go out of our way to help you relocate to Berlin, and we will do what we can to help you acquire a work permit. You should be able to communicate effectively in English. Knowing German is not required, but we will arrange and cover to costs of German lessons, if desired.
