Thornton Tomasetti applies engineering and scientific principles to solve the world’s challenges. An independent organization of creative thinkers and innovative doers collaborating from offices worldwide, our mission is to bring our clients' ideas to life and, in the process, lay the groundwork for a better, more resilient future. We provide support and opportunities to our employees to achieve their full potential and cultivate a rewarding career.
The Role
Thornton Tomasetti is seeking a Senior Engineer to join our Mississauga-based Acoustics, Noise & Vibration team. This role is primarily focused on structural vibration assessment, design, and control for buildings, infrastructure, and vibration-sensitive environments.
The successful candidate will work across the project lifecycle - from early design and performance criteria through modelling, field testing, mitigation design, construction support, and commissioning. The role is well suited to an engineer who enjoys solving complex dynamic problems, working directly with project teams and clients, and developing practical solutions that balance performance, constructability, cost, and schedule.
Our work includes the assessment and control of vibration arising from human activity, building services, equipment, transportation, construction, wind, and other sources. Projects may include laboratories, healthcare and imaging facilities, advanced manufacturing, cultural and assembly spaces, offices, residential buildings, long-span structures, and other vibration-sensitive environments.
What you’ll do:
- Lead or independently deliver structural-vibration studies for new and existing buildings and infrastructure.
- Establish project-specific vibration criteria and assessment methodologies in coordination with clients, architects, structural engineers, mechanical engineers, equipment vendors, and other consultants.
- Perform analytical and numerical assessments of floor and building vibration, including modal analysis, frequency-response analysis, time-history analysis, and other appropriate dynamic-analysis methods.
- Evaluate vibration from footfall, rhythmic activity, machinery, HVAC systems, transportation, construction, wind, and other sources.
- Plan and conduct field measurements, including instrumentation, test setup, data acquisition, signal processing, interpretation, and reporting.
- Develop and compare vibration-control strategies, which may include structural layout and framing modifications, mass and stiffness changes, damping treatments, equipment isolation, resilient supports, tuned mass dampers, and operational controls.
- Coordinate vibration requirements with structural systems, architectural layouts, floor assemblies, equipment supports, building services, and construction sequencing.
- Apply engineering judgment to translate technical results into clear recommendations that can be implemented by the project team.
- Prepare technical memoranda, reports, calculation packages, specifications, design criteria, drawings, and presentations.
- Review technical work prepared by junior staff and contribute to project QA/QC.
- Mentor Engineers and other early-career staff through technical guidance, fieldwork, modelling, and report development.
- Participate in client and design-team meetings, site reviews, construction meetings, and commissioning activities.
- Support proposals, scope development, fee preparation, interviews, and the identification of additional opportunities.
- Contribute to the team’s methods, tools, lessons learned, and continued development of structural-vibration practice.
What we’re looking for:
- A bachelor’s or master’s degree in civil, structural, or related engineering; a degree in applied mechanics, physics, or a closely related field may also be considered.
- Approximately 5–10 years of relevant consulting, research, or applied engineering experience in structural dynamics, building vibration, or a related field.
- Demonstrated experience independently delivering technical studies and communicating recommendations to clients and multidisciplinary project teams.
- Strong understanding of structural dynamics, vibration measurement, signal processing, dynamic loading, and human-perception or equipment-performance criteria.
- Experience developing and interpreting finite-element or other numerical models for vibration assessment.
- Experience with field instrumentation and vibration testing, or a strong interest and aptitude for developing this capability.
- Experience designing or evaluating practical vibration-control measures.
- Strong technical writing, presentation, organization, and communication skills.
- Ability to manage multiple assignments, coordinate with others, and deliver high-quality work within project budgets and schedules.
- Eligibility for professional registration as a Professional Engineer in Ontario; P.Eng. registration is an asset.
- A collaborative, curious, and practical approach to problem-solving.
Valuable additional experience
- Footfall-induced vibration assessment and mitigation.
- Vibration-sensitive laboratories, healthcare or imaging facilities, advanced manufacturing, or other high-performance environments.
- Dynamic testing of floors, structures, equipment, or building services.
- Vibration isolation, resilient supports, tuned mass dampers, or other passive and active control systems.
- Construction vibration assessment, monitoring, and mitigation.
- Experience with structural analysis, finite-element, data-acquisition, signal-processing, or scientific-computing software.
- Programming or automation experience using Python, MATLAB, or similar tools.
- Familiarity with relevant vibration standards, guidelines, and industry criteria.
- Experience preparing proposals, developing client relationships, or contributing to business development.
