Letter preview — tailored to Wallace Hind Selection
Dear Hiring Manager,
Water treatment and EPC sales demand a rare combination of technical credibility and commercial patience — two qualities I have developed over five years winning major projects across long, specification-led sales cycles. The Technical Sales Manager opportunity at Wallace Hind Selection appeals directly because of its focus on early-stage EPC engagement and the autonomy to build a new channel from the ground up.
My background in technical sales within the water and industrial sectors has equipped me to engage confidently at specification stage, review process documentation and P&IDs, and collaborate with internal engineering teams to produce compliant, commercially viable tender submissions. I have consistently built pipelines exceeding £1.5M annually by targeting EPC contractors at project inception rather than at competitive tender stage, which has resulted in a higher conversion rate and stronger client relationships.
