GTM Engineer - Valcat - Remote

(2025-01 - 2026-12)

• Built and maintained Clay enrichment workflows to source, clean, and enrich B2B target-account and contact lists for outbound campaigns.
• Designed waterfall enrichment sequences — free and native sources first, paid providers only when prior columns returned empty — to cut Clay credit burn while keeping match rates high.
• Extended Clay beyond its native integrations using HTTP API columns and webhooks: called external email-validation and enrichment endpoints and pushed verified leads into Smartlead and Instantly.
• Validated emails before send to reduce bounce rates and protect domain deliverability.
• Segmented accounts by ICP fit and intent signals (hiring, funding, tech stack) to prioritise high-value enrichment and stretch limited credits.
• Supported SDR and outbound efforts by improving data quality, personalisation variables, and targeting accuracy.
