• Strong proficiency in full lifecycle systems engineering for embedded systems, with the ability to operate effectively in fixed-price, schedule-driven environments while supporting Agile development practices.
• Hands-on experience defining, refining, and maintaining traceable requirements baselines, including system modeling, analysis, and verification aligned to program commitments.
• Demonstrated capability to support system architecture definition, decomposition, design reviews, and configuration-controlled updates throughout the hardware/software lifecycle.
• Experience managing program and engineering workflows using tools such as Jira.
• Deep understanding of embedded systems, hardware/software integration, interface control, and data-driven decision-making across complex system interactions.
• Ability to obtain a clearance.

• Experience supporting government or defense-related research, development, or acquisition programs.
• Familiarity with requirements management tools such as DOORS or similar platforms.
• Experience coordinating multidisciplinary engineering teams and aligning Agile development with fixed-price contractual deliverables.
• Knowledge of environmental qualification standards and testing methods such as MIL-STD-461 and MIL-STD-810.
