Senior / Principal Nuclear Safety Engineer

Sheffield, South Yorkshire, England, United Kingdom

Overview

Do you enjoy working in safety critical industries? Do you like delivering solutions to technically complex problems? Join us as a Senior / Principal Nuclear Safety Engineer and play a vital role in assessing the risks for our nuclear clients to help them and us to realise our low carbon energy ambitions, shaping a better future for our planet and its people.

Your role

  • On a typical day working in this role, you might be leading a team to produce a hazards assessment or authoring a complex safety case, justifying, and supporting the critical decision-making in the design, operation, and/or decommissioning of nuclear facilities. On another day you may be working to influence the client's strategic direction to support obtaining a nuclear site licence for their innovative design, networking to develop the business pipeline within your capability or doing a technical presentation to the regulator.
  • This role will also provide you with the opportunity to work with diverse clients from defence, nuclear generation and nuclear new build including innovative players from the fusion and SMR markets. You will be keen to lead technical delivery of projects, address technically complex problems and present the solutions to different stakeholders. You will have the drive to deliver excellent technical work, paying attention to detail without missing out on the bigger picture.
  • You will have the opportunity to contribute to and learn from the wider technical community within AtkinsRéalis, taking advantage of the global expertise we have to foster collaboration within multidisciplinary engineering teams. You will also play a vital role in developing and mentoring junior engineers to further support our growth and improve our capability for project delivery to clients whilst strengthening your leadership skills.
  • AtkinsRéalis is committed to promoting a diverse and inclusive community - a place where we can all be ourselves, thrive and develop. To help embed inclusion for all, from day one, we offer a range of family friendly, inclusive employment policies, flexible working arrangements (such as flexible hours, reduced working days, remote working etc.) and employee networks to support staff from different backgrounds. We understand the need for a diverse and flexible workforce, where there is no fixed 9 'till 5, no need for a 5-day week, no requirement for a full-time contract, and no requirement to spend all your working time in the office. Making sure you're supported is important to us so if you identify as having a disability, tell us ahead of your interview and let's talk about any adjustments you might need.
  • We have offices in Bristol, Manchester, Epsom, Derby, Sheffield, and Glasgow. This enables flexibility in where the role would be based.
  • Competitive salary: £50,000+ per annum plus additional pay in line with our performance philosophy and recognition culture.
