Position Description

If you have a sixth sense for data science, there’s a digital revolution underway in the UK working in the Emerging Technology Practice that needs the talents of a Data Scientist who is analysing, managing, designing and predicting complex datasets and breathing life into AI systems.

From public service transformation to cutting-edge commercial projects, our work has a wide reach, helping make the everyday easier, for everyone. When you start your CGI story, not only will you be improving people’s lives, you can be sure we’ll do the same for you.

Alongside a competitive salary, we offer you our share scheme (3% + 3% matching) making you a member not just an employee. You also have the option to benefit from private medical and dental insurance, flexible retirement options, childcare vouchers and a cycle to work scheme.

As for the future? We work as one team, and are a Top 100 employer. Be a successful part of
our story and we’ll support you in taking your career anywhere you want it to go.

Your future duties and responsibilities

In this role you will join our innovative Advanced Analytics capability with a primary focus on applying data mining techniques, carrying out statistical analysis and building high quality prediction systems integrated with CGI products.

You will work closely with Selecting features (building and optimising classifiers using machine learning techniques), Data-mining using state-of-the-art methods, extending CGI’s data with third party sources of information and enhancing data collection procedures to include information that is relevant for building analytic systems.

In addition, you will be involved in the processing, cleansing, and verifying the integrity of data used for analysis, be able to create automated anomaly detection systems, track performance and carry out other ad-hoc analysis as required.

Required qualifications to be successful in this role

We’re looking for demonstrable experience as a Data Scientist, who can demonstrate an excellent understanding of machine learning techniques and algorithms (neural networks and some of: k-NN, Naive Bayes, SVM, Decision Forests, etc.). We’re looking for core experience with common data science toolkits (Python, NumPy, MatLab, Tensorflow, keras, etc, with a likelihood of core skills in one of these).

Overall, we are interested in hiring someone with solid applied statistics skills, such as distributions, statistical testing, regression, etc., who is looking to progress their career in a progressive and forward thinking environment. Suffice to say we are also looking for well-developed interpersonal skills - clear, concise – with a passion for latest business innovations and their application to clients’ challenges.

Any one of these skills would be of interest but not essential:
• Experience with data visualisation tools (Matpotlib, GGplot, PowerBi etc.)
• Proficiency in using query languages (SQL, Hive, Pig, etc.)
• Database expertise across NoSQL databases (such as MongoDB, Cassandra, HBase, etc.)

You will need to be keen to learn and develop and CGI will provide you the support and training to help achieve this.
