These analyses will be re-run at intervals as the design progresses to track figures of merit, improve confidence in design performance and inform both system design and structural assessments. Working closely with multidisciplinary engineering teams, you will ensure analysis activities are prioritised, delivered and governed effectively, providing timely insights that support design decisions, substantiation and optimisation. Through the interpretation of analysis results, you will advise design teams on improvements and opportunities that can be implemented as the programme develops. This is a unique opportunity to develop and apply a whole-plant perspective, understanding how complex systems interact to deliver safe, reliable and efficient operation of a nuclear power station., * Analyse the performance of the nuclear power station across the complete energy conversion system, including reactor heat generation, steam cycle conversion, cooling water provision and electrical power generation * Deliver plant performance assessments aligned with key design iterations across the engineering function * Validate plant performance assumptions and provide functional data to support subsequent design activities * Support the development and substantiation of plant systems through high-quality analysis * Interpret analytical results and provide recommendations to improve plant performance and optimise design solutions * Contribute to the development, validation and continuous improvement of analysis methods, tools and processes * Support code verification, model validation and quality assurance activities * Coordinate the work of engineers within your technical area and support delivery against agreed programmes of work * Communicate analysis outputs clearly to technical and non-technical stakeholders across the business * Establish yourself as a technical point of contact for plant performance analysis activities ## Related Videos - [DevOps for Machine Learning](https://www.wearedevelopers.com/videos/179-devops-for-machine-learning) - [Introduction to Responsible AI: Balancing Value and Risk](https://www.wearedevelopers.com/videos/1972-introduction-to-responsible-ai-balancing-value-and-risk) - [Engineering/Manager Pendulum: Generating compound interest on your career](https://www.wearedevelopers.com/videos/100348-engineering-manager-pendulum-generating-compound-interest-on-your-career) - [Empowering Retail Through Applied Machine Learning](https://www.wearedevelopers.com/videos/976-empowering-retail-through-applied-machine-learning) - [Building Trustworthy AI in Industry: Beyond Traditional Cybersecurity](https://www.wearedevelopers.com/videos/1948-building-trustworthy-ai-in-industry-beyond-traditional-cybersecurity) - [Data Science, ML & AI in the Oil and Gas Industry at NDT Global - Dr. Katja Träumner](https://www.wearedevelopers.com/videos/1308-data-science-ml-ai-in-the-oil-and-gas-industry-at-ndt-global-dr-katja-traumner) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Software Engineer Salary in The UK](https://www.wearedevelopers.com/magazine/231-software-engineer-salary-in-the-uk) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
