At L3Harris, we don’t just build communication systems — we enable mission success for our allies and partners around the world. As a Lead Pre-Sales Systems Engineer, you’ll be the technical voice that bridges innovative communications technology with real-world tactical needs. The Regional Systems Engineer (RSE) team is looking for an experienced pre-sales engineer that can design and develop tactical communications solutions for our international customers. In this customer-facing role, the systems pre-sales engineer would provide technical expertise to support the development of mission system solutions in support of new business pursuits, demonstrations, and proposal efforts within the international tactical systems business. The ideal candidate understands tactical communications with a desire to learn about new customers and cultures. This position requires the demonstrated ability to work and communicate effectively with internal organizations (Sales, Program Management, and Product Line Management) to complete assigned projects. You will work directly with the international sales team, key customers, stakeholders, and partners in support of growing the international business unit. You’ll collaborate directly with international defense customers, design integrated mission systems, and influence how global forces connect in the most demanding environments. This role combines engineering depth, strategic engagement, and the excitement of shaping next-generation tactical networks across diverse cultures and regions.
