Job Summary

To support our extraordinary teams who build great products and contribute to our growth, JetCool is looking to add a Sales Engineer located in Littleton, MA or Austin, TX.

Reporting to the Vice President of Marketing and Partnerships, this role supports our OEM group, with a primary focus on supporting and expanding our partnership with Dell and other global system manufacturers. This role blends deep technical fluency with customer-facing leadership, helping OEM partners understand how JetCool's liquid-to-liquid and liquid-to-air cooling architectures integrate into their server platforms and align with end-customer requirements.

You will serve as the technical bridge between JetCool's engineering teams and OEM customers, ensuring our SmartPlates, CDUs, and full-stack cooling solutions meet the thermal, mechanical, and integration needs of next-generation AI and high-density compute systems.

Success in this role requires translating the customers' technical requirements into actionable server and rack-level architectures, collaborating closely with OEM teams.

What a typical day looks like:
  • Lead technical discovery with Dell and other OEM customers to understand system-level thermal requirements for AI and HPC platforms
  • Map JetCool's liquid-to-liquid and liquid-to-air cooling architectures to OEM server designs, rack-level strategies, and customer deployment models
  • Serve as the primary technical interface for customer engagements, guiding customers through solution feasibility, integration, and performance expectations
  • Support sales cycles by contributing to quotes, configuration analysis, RFP/RFQ responses, technical documentation, and customer-facing content
  • Gather and interpret OEM requirements, specifications, and system documentation for JetCool Engineering
  • Collaborate with Engineering to define, refine, and communicate cooling solutions-including cold plates, manifolds, CDUs, and rack-level integration
  • Evaluate server and rack architectures (Dell PowerEdge, GPU platforms, AI accelerators, etc.) to ensure compatibility with JetCool solutions
  • Develop and deliver technical presentations that highlight JetCool's differentiation in thermal performance, efficiency, and sustainability
  • Present thermal analyses in a clear, consumable format for both engineering and business stakeholders
  • Adapt technical depth and messaging in real time based on audience, context, and customer priorities


The experience we're looking to add to our team:
  • 3+ years in pre-sales engineering, OEM engagement, or customer-facing technical roles
  • Ability to interpret and communicate complex engineering analyses
  • Strong communication, presentation, and customer-facing skills
  • Experience with fluid-based mechanical designs or thermal systems is preferred
  • Exposure to CFD tools (ANSYS, Icepak, FloTHERM) is a plus
  • Experience applying heat-transfer and fluid-mechanics fundamentals to real-world cooling solutions is preferred
  • Familiarity with server architectures, AI accelerators, and OEM design cycles (Dell experience strongly preferred)


What you'll receive for the great work you provide:
  • Full range of medical, dental, and vision plans
  • Life Insurance
  • Short-term and Long-term Disability
  • Matching 401(k) Contributions
  • Vacation and Paid Sick Time
  • Tuition Reimbursement
