An ALL4 Senior Technical Consultant serves as technical expert for one or more of ALL4’s key Technical Service Areas and has established recognition within their technical, peer, and regulatory communities. We are seeking acoustics, noise, and vibration subject matter experts to serve ALL4’s industrial client base. The Senior Technical Consultant has established technical expertise across ALL4 service areas(s) and can solve the complex technical problems that arise without other senior level assistance. This individual actively seeks opportunities to increase ALL4’s visibility through technical presentations and other venues and are responsible for driving existing and new business revenues generated within those venues. The Senior Technical Consultant has extensive relationships with clients and partners that allow them to drive work that can be delegated to two or more project team members at a given time. It is preferable to have this individual work at an ALL4 office; however, working remotely can be discussed as an option contingent upon experience.
