Requirements:

  • +5 years customer-facing experience in a technical role (engineering, presales, technical solutions, etc). Proven experience working with technical partners or ISVs
  • Strong communication skills in English (verbal & written)

  • Experience working directly with enterprise customers on technical implementations — translating business workflows (e.g., "generate branded proposals from our CRM data") into working integrations, not just architecture diagrams
  • Strong technical communication: you can debug a partner's code on a call, lead an architecture discussion with an enterprise IT team, and write documentation that developers actually use
  • Proactive and self-directed — you see a gap (missing docs, broken integration, partner blocked on an issue) and fix it without waiting to be asked

  • Work directly with B2B customers
  • Architect integration workflows with enterprise customers — understand their systems, map their use cases, and get them to production
  • Translate customer workflow requirements into API product feedback: what endpoints are missing, what context needs to flow, what breaks at scale
  • Own technical security and compliance conversations (SOC 2, SSO, data residency) with enterprise buyers and their procurement teams
  • Enable partners building on Gamma
