• Understanding customer needs
• Sales engineers analyze customer needs and requirements, and recommend technology products based on that understanding. 
• Making technical presentations
• Sales engineers prepare and deliver technical presentations to customers and prospective customers. They showcase the product's key features and benefits, and address customer concerns. 
• Sales engineers negotiate and close sales by agreeing on terms and conditions. They also negotiate tender and contract terms. 
• Sales engineers develop and maintain relationships with key customers to ensure customer satisfaction and loyalty. 
• Sales engineers collaborate with sales teams to provide feedback, ideas, and strategies. 
• Helping design custom-made products
• Bet the liaison between the customer and after sales team.

Sales engineers need strong communication and listening skills, and may need to know more than one language.
