Be a trusted bridge between customers and engineers ● Translate customer needs into clear, structured, and actionable client briefs. ● Work closely with the engineering team to clarify input data, technical limitations, possible solutions, and items requiring further validation. ● Explain technical concepts in language suited to different decision-makers, including operations, engineering, finance, and factory leadership. ● Never promise beyond what the technology can deliver or turn an assumption into a commitment. 3. Build high-quality proposals ● Support the preparation of proposals, technical documents, presentations, meeting notes, and customer responses. ● Ensure every proposal accurately reflects the problem, available data, scope of work, assumptions, and next steps. ● Follow up on open questions after meetings and coordinate handovers so that important information is not lost. ● Contribute to the team’s library of discovery questions, field lessons, and technical sales materials. 4. Support projects when needed ● Support customers during site surveys, pilot tests, installation, commissioning, acceptance, and on-site troubleshooting. ● Be willing to travel based on project requirements. ● When a project requires after-hours or on-site support, step in with a strong sense of responsibility while working with the team to ensure a reasonable recovery plan afterward.
