M.Sc. or Ph.D. in engineering would be nice to have. * Minimum of 5 years of experience in systems engineering. * Experience with requirements engineering. * Demonstrated ability to break down complex systems into manageable pieces. * Capability to perform content-based multifaceted trade-offs/balancing within the triple constraint framework. * Instinctive ability to challenge constructively. * Nuclear plant systems design. * Systems engineering methodologies. * Multidisciplinary integration. * Model-Based Systems Engineering. * Familiarity with CAD/plant design tools. Nice-to-haves * Experience in the nuclear industry or a comparable high-integrity safety environment. * Demonstrated knowledge of nuclear plant systems design and safety analysis principles. * Familiarity with Model-Based Systems Engineering (MBSE) and tools such as SysML or Cameo Systems Modeler. * Experience with Jira and Confluence, RAMI analysis, Quality Assurance, Licensing processes. ## Description As Systems Engineer / Architect for the Reactor System, you will lead the architecture, integrated design, analysis, and development of the fusion island across the full engineering lifecycle - from concept and preliminary design through detailed design, commissioning support, and operations readiness. Working at the interface of multiple engineering disciplines, you will ensure that plant systems are safe, reliable, fully integrated, and compliant with regulatory requirements. You will oversee reactor and fusion island activities with a focus on technical interdependencies, alignment with key design and construction objectives, and delivery against major project milestones. A core responsibility of the role is to ensure that the final plant design is coherent, safe, and licensable. What You'll Do * Lead, support and drive the systems engineering process including the fusion island and the fuel cycle. * Develop, enforce and maintain system architecture, design descriptions, design basis documents, requirements, and interface control documents. * Baseline definition and maintenance. * Identify and promote system-level trade studies and design option analyses to optimize performance, safety, and cost. * Ensure proper integration of all disciplines into a coherent plant design. * Apply safety principles including defense-in-depth, single failure criterion, and diversity and redundancy requirements. * Participate in design review meetings, safety review committees, and independent verification and validation (IV&V) activities. ## Related Videos - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) - [42 x 2 Canvases Later: Two Years, Two Minds, Many Lessons](https://www.wearedevelopers.com/videos/1458-42-x-2-canvases-later-two-years-two-minds-many-lessons) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [A Founder's Journey : From Startup Chaos to Purposeful Growth](https://www.wearedevelopers.com/videos/1926-a-founder-s-journey-from-startup-chaos-to-purposeful-growth) - [Designing UX for SRE Agents in High-Stakes Incidents](https://www.wearedevelopers.com/videos/100003-designing-ux-for-sre-agents-in-high-stakes-incidents) - [Integrate your Cognitive Assistant with 3rd-party DBs and software](https://www.wearedevelopers.com/videos/249-integrate-your-cognitive-assistant-with-3rd-party-dbs-and-software) ## Related Articles - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [What Jobs Can You Get with a Software Engineering Degree?](https://www.wearedevelopers.com/magazine/398-what-jobs-can-you-get-with-a-software-engineering-degree) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [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)
