Internal Technical Sales Engineer

Internal Technical Sales Engineer, £40,000 Basic + Uncapped Commission (realistic Year One OTE of £57,000) plus private health, life assurance, pension and progression opportunities. Based in Chelmsford, our client is a market-leading manufacturer and supplier of process control, automation, and energy management equipment, each with a unique technical advantage, allowing them to take on complex, high-value engineering challenges that our competitors cannot match. The company enjoys an entrepreneurial culture and a proven history of promoting from within. Your sales manager started in this role, then progressed to field sales and then to sales management. The Sales Director also started his career in this role.

Working within an established internal sales team of four and working closely with the technical engineering team, this role blends inbound technical advisory work with structured, proactive business development. You will act as a trusted advisor to end-user clients, turning routine product enquiries into comprehensive, high-value solutions. The role is 80% inbound leads and account management, with 1 hour per day dedicated to proactive business development, primarily for dormant accounts.

The role is handling incoming technical inquiries regarding product specifications, drawings, and applications to help customers select the right solutions. It therefore requires someone with a technical sales background who is nosy and likes to know how clients do things! It requires someone that is a 'sponge for information' who will look beyond the initial inquiry to understand what the client is looking to achieve and often taking a £5K product enquiry to a £250K project. The role needs someone who can spot an opportunity and upsell.
