Pay Range: $100,000 - $130,000 + Bonus Eligible 

Who we are: Lynx delivers modular, open standards-based software solutions that redefine the economics of developing, deploying, and maintaining high assurance, mission critical edge platforms. These secure edge computing solutions are designed to drive innovation and operational excellence in today’s most demanding environments. From advancing aerospace and defense capabilities to transforming commercial and industrial systems, Lynx collaborates across a wide range of industries, including automotive, medical, and critical infrastructure, to deliver tailored, high assurance solutions aligned with specific mission and operational requirements. Our key products and services are: 

• LYNX Mosaic: A software platform that can include a LYNX safety-critical real-time operating system. MOSAI.ic's modular design provides robust support for multicore processing. It allows different operating systems and applications of different criticality levels to be run on separate cores for improved performance, reliability, and security.
• CoreSuite 2.0: A suite of graphics libraries and tools that enable GPU hardware acceleration for both graphics and "GPU Compute", supporting applications such as machine learning and AI processing in edge devices.
• MOSA.ic.SCA and Vigiles, tools that provide Software Bill of Materials (SBOM) and Common Vulnerabilities Exposure (CVE) management for embedded Linux-based and other applications.
• Software development services for high-reliability applications that can include initial setup of a "DevSecOps" development environment, software application development, and long-term product lifecycle management. 

Role Overview

The Systems Test Engineer will be responsible for developing, writing, and executing system-level test cases to validate Lynx products against customer requirements, specifications, and safety standards. This role requires close collaboration with systems engineers, software developers, and quality teams to ensure full coverage of functional, performance, and safety objectives. This position emphasizes test case design, development, and documentation across the full test lifecycle.

Key Responsibilities

• Develop detailed system-level test cases based on system requirements, specifications, and design documents.
• Produce and maintain test documentation including test procedures, test scripts, test reports, and traceability matrices.
• Execute system test cases in both lab and simulated environments; document and report results.
• Perform functional, integration, performance, and regression testing at the system level.
• Collaborate with systems and software engineering teams to clarify requirements and identify testable conditions.
• Identify, reproduce, and document defects; work with development teams to support root-cause analysis and resolution.
• Ensure traceability from requirements to test cases and test results.
• Participate in formal test reviews, audits, and certification activities where applicable (e.g. DO-178, ARP4754).
• Contribute to continuous improvement of test methodologies, processes, and tools.

·        Perform additional job duties as assigned.

Required Qualifications

• Bachelor’s degree in Systems Engineering, Electrical/Computer Engineering, Computer Science, or related technical discipline.
• 3+ years of experience in system-level testing of complex embedded, avionics, or safety-critical systems.
