Sr. Electronics Design Engineer

About the role

Long Wall Company was founded in 2024 with a clear mission: to accelerate missile defense technology for the United States and its allies. The company leverages existing RS1 and GS0 launch systems to develop containerized, mass-producible missile defense solutions. Long Wall provides rapid, low-cost flight testing capabilities. The company holds a firm belief that global security and stability depend on defensive technology that is lower cost, higher performing, better tested, and more broadly distributed than what currently exists. The organization seeks mission-driven problem solvers who view the aerospace frontier as a space for ingenuity. Candidates are expected to approach challenges with curiosity, view failure as a learning opportunity, and maintain unwavering focus on delivering the optimal solution for the mission. Collaboration is essential, as no one succeeds in isolation, and the best engineers, corporate professionals, and technicians elevate their teammates. Success at Long Wall stems from recognizing that complementary skills create force multiplication and drive mission achievement.

Sr. Electronics Design Engineer

This position involves owning the complete electrical lifecycle for defense hardware, guiding concepts from initial specifications through to operational deployment. The engineer's work determines whether mission systems succeed or fail under strict test conditions, solving complex integration puzzles that are critical for keeping flight campaigns on schedule. They act as a responsible engineer, contributing directly to every mission and every flight as the company reimagines the future of missile defense systems. This role requires a high level of ownership and technical judgment to ensure the electrical systems meet the rigorous demands of the defense sector.

What you'll do

• Architect signal chains and power networks while coordinating closely with mechanical teams to ensure system-level compatibility.
• Define rigorous test procedures designed to expose weaknesses in the hardware before it ever reaches the range or launch platform.
• Guide printed circuit board layout to satisfy strict timing, noise, and electromagnetic compatibility specifications.
• Establish vendor and supplier interfaces to ensure modules integrate cleanly on the first attempt, reducing rework and delays.
• Oversee component qualification, screening, and trace documentation to satisfy stringent audit and compliance requirements.
• Conduct prototype validation in simulated operational conditions and refine the design based on empirical data and test results.
• Coordinate with analysis groups on electromagnetic and thermal performance modeling to predict and mitigate potential failures.
• Support integration trials, flight tests, and long-term monitoring to confirm system reliability in real-world scenarios.
• Translate complex system requirements into detailed electrical schematics and specifications for the engineering team.
• Troubleshoot unexpected electrical behavior during testing and collaborate with cross-functional teams to implement robust fixes.
• Ensure all designs adhere to military standards, validation processes, and documentation protocols from inception to completion.
• Mentor junior engineers by providing technical guidance and setting a high standard for design quality and thoroughness.
