Dear Hiring Manager,
Water treatment EPC sales is a discipline that rewards early specification influence and technical credibility — two areas where I have built a consistent track record. The Technical Sales Engineer opportunity at Wallace Hind Selection appeals directly because of its focus on developing the EPC channel from the ground up, requiring both consultative engagement and the ability to navigate complex, multi-year sales cycles.

I have managed accounts through sales cycles of 12 to 18 months, building pipeline across EPC and major project clients and securing project awards in the £500k–£1.5M range.
