Senior EO/IR Systems Engineer

LongwallLong Beach, California2d ago

Long Wall Company was created in 2025 to accelerate missile defense technology for the U.S. and our allies. Building on the RS1 and GS0 launch systems, Long Wall develops containerized, mass-producible missile defense systems and offers rapid, low-cost flight testing. We believe that the future of global security and stability require defensive technology that is lower cost, higher performing, better tested, and more broadly distributed than is possible today. Join us.

What we look for

Mission-Driven Problem Solvers. The aerospace frontier demands ingenuity. We want engineers who approach challenges with curiosity, embrace failure as a learning opportunity, and stay focused on delivering the best solution for the mission.

Total Ownership. We seek engineers who take full responsibility for delivering flight-ready work while recognizing that no one succeeds alone. The best engineers make their teammates better, knowing that complementary skills create force multiplication and drive mission success.

Long Wall is seeking a Senior EOIR Systems Lead to architect, build, and lead our complete electro-optical and infrared sensing pipeline for advanced interceptor systems. This is a technical leadership role requiring deep expertise across the entire EOIR chain—from synthetic scene generation to sensor physics modeling, and from real-time image processing and tracking algorithms. You will own the critical path for seeker capability development, working at the intersection of physics-based modeling, algorithm design, and real-time system integration. This role requires both hands-on technical contribution and the ability to build and mentor a team.

Responsibilities

Scene Generation & Radiometry

Architect and implement IR scene generation capability for high-fidelity missile seeker simulation

Develop physics-based radiometric models (target signatures, backgrounds, atmospheric effects)

Integrate commercial scene generation tools into our real-time simulation pipeline

Sensor Physics Modeling (EOSM)

Build electro-optical sensor models capturing optics, focal plane arrays, and readout electronics

Model detector noise characteristics, optical aberrations, and signal chain performance

Validate sensor models against hardware characterization data

Signal Processing & Tracking Algorithms

Design and implement detection, tracking, and aimpoint selection algorithms for terminal guidance

Develop multi-target discrimination and track management logic

Optimize algorithms for real-time execution on embedded processors

System Integration

Integrate EOIR chain into hardware-in-the-loop (HIL) test infrastructure

Work closely with the flight software team on sensor interfaces and message protocols

Support Monte Carlo performance assessment and statistical analysis

Team & Technical Leadership

Build and lead the EOIR engineering team as the program scales

Define technical roadmaps and architecture decisions for seeker development

Mentor junior engineers and establish best practices
