Job Summary

**The big picture**

CSE plays a critical role in the implementation of Canada’s cyber security strategy. To carry out our mission we track cyberthreats around the world, monitor Government of Canada networks to detect and mitigate cyberthreats, and protect information of value to the government. CSE’s data analysts/scientists play a crucial role in generating insight from data-rich environments.


 *What’s in it for you?*

Are you interested in a unique working experience applying data analyst/science skills to a diverse variety of cyber defence problems? At CSE, data analysts and data scientists are motivated by an environment with:

  • interesting and distinct problems to solve
  • talented colleagues
  • encouragement to approach problems from different perspectives
  • continuous learning and development to maintain a technical edge
  • opportunities to see the impact of their efforts

If the above description sounds attractive, you should consider CSE for a career in data analysis/science. Data analysts perform data review, data validation, quality control, and cleaning; they develop and evolve Extract, Transform, Load (ETL) processes and data models; they create data processing pipelines to analyze disparate multi-source data; they prepare technical documentation and standard operating procedures; and they ensure data requirements are met for operational reporting, dashboards and ad hoc requests.

Data scientists model real world problems to forecast what might happen; they apply and develop machine learning techniques, they implement algorithms in efficient and scalable ways; they communicate analytical results to others in compelling and visual ways; they help to develop scalable solutions; and they mentor others and help others to communicate and gain understanding about data science.
