Algorithmic Developer to join High Frequency Hedge Fund

I am looking for a junior Quant Dev to work for a privately owned, London based, hedge fund to work on algorithm development and tuning.

The candidate needs to be very bright and sharp at solving puzzles, with an analytical mind, that is quick to implement algorithms.

You will have:
- A background in engineering/science with a PHD from a top university.
- Ability to code JAVA
- Ability to use Excel
- Ability to communicate easily

I am looking for a junior PHD, someone new to finance, but would however consider someone who has spent a year or two in finance, as long as the above conditions are met.
