What is a flex developer?

A Flex Developer is a software developer who specializes in building applications using Adobe Flex, a framework for creating rich internet applications (RIAs) that run on Adobe Flash Player or Adobe AIR. They use ActionScript, MXML, and other web technologies to develop interactive and multimedia-rich user interfaces. Flex Developers often work on enterprise applications, dashboards, or media-heavy applications that require a high level of engagement. Although Adobe has discontinued support for Flash Player, some legacy systems still require Flex expertise.

What are the key skills and qualifications needed to thrive as a flex developer?

To thrive as a Flex Developer, you need strong proficiency in programming languages such as ActionScript and frameworks like Adobe Flex, along with experience in UI/UX development for web and desktop applications. Familiarity with integrated development environments (IDEs) such as Adobe Flash Builder and knowledge of related technologies like XML, Java, or web services is important, and certifications in software development can be advantageous. Excellent problem-solving skills, attention to detail, and effective collaboration with designers and back-end developers are highly valued soft skills. These qualifications are essential to efficiently build, maintain, and enhance dynamic, user-friendly enterprise applications that meet client requirements.

What are the typical projects or responsibilities for a flex developer?

Flex Developers are commonly responsible for designing, coding, and maintaining interactive applications using Adobe Flex, often integrating these with back-end services and databases. They typically collaborate with UI/UX designers to implement visually appealing and user-friendly interfaces, and work hand-in-hand with QA teams to troubleshoot and resolve application bugs. Projects may range from internal enterprise dashboards to customer-facing web applications, depending on the organization's focus. Additionally, Flex Developers are often expected to stay updated with evolving frameworks and contribute to optimizing existing applications for better performance and scalability.

Job description

At JetCool, a Flex company, we're at the forefront of liquid cooling innovation, delivering advanced solutions that empower our partners in AI and high-performance computing. United by a shared purpose, our teams are pushing the limits of what's possible and tackling complex challenges.
A career at JetCool offers the opportunity to make a real impact by helping build smarter, more sustainable data centers. Together, we're not just advancing technology - we're redefining cooling standards to create a more sustainable tomorrow.
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
