Senior Process Engineer

At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission‑critical outcomes, operational advancement, scientific discovery and cutting‑edge manufacturing, turning abstract ideas into realities that transform the world for good.

The Senior Process Engineer will play a key role in delivering high‑performance manufacturing solutions across Jacobs’ Advanced Manufacturing portfolio. This role focuses on developing, optimizing, and validating production processes for clients in sectors such as semiconductors and high‑tech manufacturing. The engineer will work within multidisciplinary project teams to design robust processes, improve efficiency, and ensure compliance with industry standards and client requirements.

• Lead process design activities including mass/energy balances, PFDs, P&IDs, hydraulic/pressure loss/relief calculations, capacity and utility analysis, equipment sizing, and process modelling for new and existing manufacturing systems.
• Develop and optimise manufacturing processes to improve throughput, yield, safety, sustainability, and cost efficiency.
• Support front‑end engineering design (FEED), detailed design, commissioning, and start‑up activities for advanced manufacturing facilities.
• Conduct process hazard analyses (HAZOP, LOPA, ATEX) and ensure alignment with safety, regulatory, and quality standards.
• Review conformity with relevant EU Directives – typically PED, ATEX, Machinery Directives.
• Collaborate with mechanical, electrical, controls, and project management teams to deliver integrated engineering solutions.
• Estimate, plan and schedule the discipline scope for a project.
• Prepare technical documentation including specifications, design reports, operating procedures, and validation protocols.
• Engage directly with clients to understand requirements, present design solutions, and support decision‑making throughout the project lifecycle.
• Troubleshoot process issues and provide technical guidance during construction and commissioning phases.
• Contribute to continuous improvement initiatives and the development of best practices within the Advanced Manufacturing team.

• Bachelor’s or Master’s degree in Chemical Engineering, Process Engineering, Mechanical Engineering, or a related discipline.
• 8–12+ years of experience in process engineering within advanced manufacturing, industrial engineering, or a related high‑tech sector.
• Familiar with applying relevant Pressure Vessel and Piping Standards – US and EU.
• Proven experience with process design tools (e.g., Pipe Flo, PIPESYM, PIPEPHASE, ChemCAD, or equivalent).
• Strong understanding of process safety, risk assessment methodologies, and regulatory frameworks.
• Demonstrated ability to work in multidisciplinary teams and manage multiple project priorities.
• Experience supporting commissioning, start‑up, or operational troubleshooting.
• Excellent communication skills and the ability to engage effectively with clients and internal stakeholders.

• Experience in semiconductor, biotech, pharmaceutical, battery manufacturing, or other high‑purity/cleanroom environments.
• Knowledge of sustainability principles, energy efficiency, and decarbonisation strategies in manufacturing.
• Knowledge of data analysis, design of experiments, and Six‑Sigma analysis and practices.
• Familiarity with EU Directives relevant to engineering design – ATEX, PED, Machinery Directive, Industrial Emissions Directive.
• Familiarity with digital engineering tools, data analytics, or automation/controls integration.
• Chartered Engineer status or other professional accreditation.
• Coordination of Piping Design experience – able to use and review piping specifications, experienced in piping design coordination or representing the Process Discipline during this coordination.
• Specification of Turnkey Vendor scope, and coordination of Turnkey design with in‑house design and design by others.
• Layout development and coordination, review and coordination of requirements with Architects and other disciplines.
• Control system development, experience of working with I&C…
