Improving some algorithms and calculations that predict future energy scenarios. The prediction engine is programmed in Ruby, so performance is low (we chose ruby because of inhouse knowledge and it makes it easy to discuss with domain experts). Now, fine-tuning/micro-optimising the computation to optimize speed, so that it's fast enough for a web-request (< 200ms).
i sublet an old, rusty, worndown (with views on a canal) 1 bedroom appartment in the best part of town (jordaan) for 900€/month. The bigger problem in amsterdam is to find something.
If interested check http://www.energytransitionmodel.com/ there you can build future energy scenarios. For instance see that you're far better off when you invest money in a better (house) insulation then in efficient light bulbs. Or how much total CO2 emissions are reduced if everybody switched to electric cars.
Very competitive benefits. But of course, it depends on the package of your choosing.
The Energy Transition Model is a complex web application in which users can build their own 'future energy scenario'. It tries to answer detailed questions such as: how much less CO2 will this or that country emit when it builds a Nuclear Power Plant, or wind mill parcs? What much will it cost? And how dependent will you be on foreign companies?
For this end, we are building an extended Ruby on Rails app, with a rich interface which shows complex charts, using no flash. (instead we use jQuery and Canvas.) To make live easy for ourselves, we use HAML, SASS and Git.
You will work in a small company of 9 dedicated employees.
Salary is well above average. Expats are also very welcome.

Senior Rails Dev needed in Amsterdam/Utrecht. They are building a web app, predicting future energy scenarios based on your assumptions - like how co2 emission, electricity and heating cost, dependence on foreign countries will change. I'm leaving this great team and project for my own venture. http://www.workingwithrails.com/opportunity/2450
Technologies: Rails 2.3, Ruby 1.9, Haml/Sass, Rspec, Git, jQuery
