Mechanical Systems Design Engineer

Mechanical Systems Design Engineer

DRONAMICS

Sofia, Bulgaria

The Role

We are seeking a Mechanical Systems Design Engineer who would conduct the physical integration of aircraft systems into our UAS with focus to bridge the gap between systems and the mechanical structure, ensuring all components are housed, installed, powered, and calibrated correctly to withstand flight environments for our next-generation UAS. Both Junior and senior applicants are welcomed.

The Responsibilities

• Detailed Mechanical Design & Modeling: Definition of specific mechanical systems requirements derived from UAS high level ones. Support concept/trade studies in coordination with System Engineering to support architectural basic choices. Using advanced CAD software (e.g., 3DX platform, SolidWorks, CATIA, NX) to create precise 3D models and 2D technical drawings for all secondary structures, aircraft systems and powerplant devices and their assemblies;
• Cross-Functional Integration: Collaborate with avionics, propulsion, software, structures and supply teams to resolve system-level trade-offs and clash resolutions (interference between parts);
• Prototyping & Testing: Building and evaluating physical prototypes to identify design flaws and iterate for better performance and to set up calibration procedures of integrated systems;
• Manufacturing & Compliance: Design and analyses tasks supporting product development activities on Mechanical systems, taking into account manufacturability and integration constraints. Defining materials and tolerances (GD&T) to ensure designs are cost-effective to manufacture and meet regulatory safety standards (ISO, ASME). Essential skills for DFM (Design for Manufacturing);
• Production & Quality: To be involved production technologies such as composite manufacturing, milling, sheet metal processing and additive manufacturing to provide qualified design and quality assurance basis;
• Certification: Ensure compliance with aerospace UAS regulations and industry standards.

Your Qualifications

• Education: Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related field or an equivalent career experience;
• Professional Experience: design and integration of systems from specific components up to entire system architectures based on engineering level of applicant, preferably in UAV or aircraft development;
• Software Proficiency: Expertise in CAD software SolidWorks, CATIA, or NX. CATIA/3DEXPERIENCE platform and basic skills in programming (Python)- advantage;
• Regulatory Knowledge: Familiarity with FAA/EASA certification (e.g., Part 21), ARP 4754, DO160G, UAS regulations (SORA framework) - advantage;
• Language: English C1 level - Bulgarian advantage.
