About DESI
Senior engineering support for demanding aerospace programs.
Dunagan Engineering Services, Inc. focuses on certification, airworthiness, systems, software, airborne electronic hardware, and multicore processor assurance.
Our approach
DESI emphasizes technical rigor, traceability, realistic program execution, and review-ready evidence. The objective is to help customers reduce certification uncertainty, expose gaps early, and establish a disciplined path to closure.
We support organizations that need targeted subject-matter expertise, independent technical review, work-product development, certification planning, or augmentation of an existing engineering team.
Operating Principles
- Safety and mission effectiveness first
- Requirements-driven engineering
- Objective evidence over assertion
- Explicit assumptions and constraints
