They’re looking to hire a Technical Lead and senior JavaScript engineers to kick-start new front end projects and establish a new team. You would be a senior engineer with experience working on greenfield projects. They’re looking for people who have previously developed significant front end architectures, had a big hand to play in technology selection such as JavaScript libraries and are used to maintaining clean extensible code. They want team players who prefer to share code, choose technologies, build common libraries, components and establish common team practices.


A rapidly expanding VC-backed startup operating in the information security sector. Their products essentially enable global clients to safely analyse and mine sensitive data sets without compromising the individuals right to privacy. Due to recent EU rule changes around data security off the back of some high profile data leaks, companies are now increasingly forced to plough resources at this area. They already have global companies and tier1 banks using their products which utilise the power of big data and machine learning to create a data analytics security safety net.
