Job description/Person specification

About the role:
We are looking to appoint an experienced scientist to fulfil a significant role in the design and implementation of Secured Navigation systems, including Global Navigation Satellite System receivers.

The role will require an individual who is confident to:
• Conduct the required background research to production timescales;
• Scope solution options for system components and generate technical requirements;
• Develop algorithms;
• Conduct verification activities and generate reports with detailed analysis of the results;
• Work alongside a dedicated software engineering team in a high control production environment.

What will I be doing?:
You will be able to work autonomously and take responsibility for the work of themselves and others, liaising with project managers and technical leads and taking ownership of discrete packages of work.

Accountabilities include:
• Research of customer needs and requirements to align technical outputs;
• Identification, review and selection of scientific techniques, procedures and methods to undertake tasks;
• Identification of risks and opportunities, monitoring through the lifetime of a project;
