What Does a Field Application Engineer Do? (Role Guide & Salary 2024)

12/04/2025

A Field Application Engineer (FAE) is a hybrid technical and commercial professional who acts as the critical bridge between a company and its clients, ensuring complex engineering products are understood, implemented, and supported effectively. This role typically requires a bachelor's degree in engineering and offers an average salary range of $75,000 to $120,000 annually, depending on experience and industry. FAEs are essential for driving customer satisfaction and long-term account growth.

What is a Field Application Engineer?

A Field Application Engineer (FAE) is a specialized role often found in companies selling complex hardware, software, or integrated technological systems. Unlike a pure salesperson, an FAE possesses deep technical expertise, allowing them to understand a client's specific challenges and articulate how their company's product provides a solution. This combination of engineering knowledge and client-facing skills makes them a key player in the sales cycle and post-sale support for technical products. They are sometimes referred to as Technical Sales Engineers.

What Does a Field Application Engineer Do? A Day-in-the-Life Breakdown?

The responsibilities of an FAE are diverse, blending pre-sale, sale, and post-sale activities. Their core duties are designed to ensure the client's technical success.

  • Pre-Sales Technical Consultation: FAEs work alongside the sales team to conduct technical presentations and product demonstrations. They are responsible for answering deep technical questions, assessing client needs, and verifying that the product is a viable fit for the client’s environment.
  • On-Site Product Implementation: After a sale, the FAE often leads the installation, configuration, and integration of the product at the client's site. This hands-on work ensures the solution works as intended within the client's unique operational framework.
  • Post-Sales Support and Troubleshooting: FAEs provide expert-level support, resolving complex technical issues that go beyond standard customer service. This includes diagnosing problems, performing repairs, and coordinating with internal engineering teams to find solutions, thereby increasing customer retention rates.
  • Staff Training and Development: A critical part of the role is empowering the client's team. FAEs develop and deliver training sessions to ensure the client's staff can operate and maintain the product effectively, maximizing its value.

What are the Key Requirements to Become a Field Application Engineer?

Becoming an FAE requires a specific blend of education and practical experience. The most common path involves:

  1. Earning a Bachelor's Degree: A bachelor’s degree in an engineering discipline such as Electrical, Mechanical, Computer, or Software Engineering is the standard requirement. This provides the foundational technical knowledge necessary for the role.
  2. Gaining Practical Experience: Most employers seek candidates with 2-5 years of experience in a hands-on engineering, technical support, or application engineering role. This experience builds practical problem-solving skills.
  3. Developing a Hybrid Skill Set: Beyond technical prowess, successful FAEs cultivate strong soft skills. The table below outlines the essential skill combination:

  • Shadow Sales Teams: Ask to accompany sales representatives on client calls to understand the commercial process and customer pain points.
  • Pursue Certifications: Industry-specific certifications related to the products or technologies you wish to support can significantly enhance your credibility and technical depth.

To build a successful career as a Field Application Engineer, focus on mastering the technical details of your product while simultaneously honing your communication and client management abilities.
