- Participate in pursuit and proposal efforts, including technical approaches, scope development, cost input, and client interviews.
- Partner with construction teams, partners, and equipment vendors to develop practical, maintainable, and cost-effective solutions.
- Identify and manage technical, operational, and construction-related risks throughout project delivery.
People & Discipline Leadership
- Lead, mentor, and develop our teams of supporting process and mechanical engineers and designers across multiple projects.
- Support workforce planning, coaching, performance feedback, and technical development within the process mechanical discipline.
- Champion Jacobs' standards for safety, quality, innovation, and inclusion.
- Contribute to the advancement of discipline best practices, standards, and technical excellence.
Client & Stakeholder Engagement
- Interface directly with internal and external clients, serving as a trusted process/mechanical engineering advisor.
- Participate in client meetings, technical workshops, coordination sessions, and project reviews. Ability to travel approximately 10% of time to client and project sites in the Midwest and Northeast regions.
- Build and maintain strong relationships with owners, contractors, equipment suppliers, and internal stakeholders.
- Support business development by strengthening client confidence and identifying future project opportunities.
Here's what you'll need
- Bachelor's degree in Mechanical Engineering, Chemical Engineering, or a related field.
- Professional Engineer (PE) license required.
- 10+ years of progressive process/mechanical engineering experience, with a strong focus on water and wastewater infrastructure.
- Demonstrated experience leading process/mechanical scope on large, complex water or wastewater infrastructure projects (design-build or alternative delivery projects preferred).
- Proven ability to lead teams, manage competing priorities, and deliver high-quality, reliable designs.
- Strong communication skills and experience working directly with clients and multidisciplinary teams. Ideally, you'll also have
