The Technical Profession consists of 550 science, technology, engineering and maths specialists, who mainly have degrees in chemistry, physics, maths, materials science and chemical/process or mechanical engineering disciplines.  They work in multi-disciplined teams spread right across the company but are mostly based on the Sellafield site or at the satellite offices in Cumbria. They focus on solving short (few days), medium (1-2 years) and long term (5-10 years) technology challenges.

All members of the Profession have or are developing a technical specialist skill and are linked to at least one of our technical specialist communities (called CoEs – Centres of Expertise). These build networks with other specialists inside and outside Sellafield Ltd, particularly with the National Nuclear Laboratory (NNL) which has a laboratory on the Sellafield site, and with academia, including links with key universities.

Typical roles and responsibilities:

The work carried out by the Profession is varied and challenging and requires people who are both innovative and self-motivated. Current graduates identify the variety of work as one of the best parts of the job. Work involves problem solving and scoping/managing Research & Development tasks carried out by technical suppliers, then applying the output to solve Sellafield Ltd technology challenges, many of which are novel and unique.

Examples of graduate roles are technical support to plant operations, setting up trials to support plant process improvements, data acquisition and data analysis. As a graduate you will also be expected to maintain relationships with external customers and Regulators and manage the interface between Sellafield Ltd plants and external companies and contractors, whilst also acting as a subject matter expert for all customers.

Progression possibilities:

There are two career paths within the profession:

Technical Specialist and Technical Manager

Specialists develop deep technical skills and grow specialist networks outside the company and managers develop wider technical skills and people management experience. Movement between the career paths is encouraged to gain depth of experience, support is provided to Graduates to ensure they have a robust development plan in place to cover their preferred career path.

The Graduate Scheme is aimed at providing you with the experience and exposure to ensure that the career path you choose is right for you and will also provide you with the experience required to support your progression towards chartered status.
