About the Role 

We are looking for a Structural Engineer to support the development of next-generation defence systems through structural strength and fatigue analysis. In this role, you will perform simulations and engineering calculations using FEA and analytical methods, assess metal and composite structures, and provide analysis reports to support qualification and safety activities. Working closely with multidisciplinary engineering teams, you will help optimise designs, evaluate test results, and contribute to the delivery of reliable, high-performance defence products.

At Frankenburg, you will join an exceptional team of leading experts in technology and national defence, building next-generation defence missile systems for the free world. You will work in a fast-paced environment where your contribution shapes how we verify and demonstrate advanced defence systems. If you thrive on innovation and impact — we want to hear from you.

Key Responsibilities 

• Structural Analysis & Simulation
  Perform structural strength, stiffness, and fatigue analyses of missile and launcher components using FEA and analytical methods to predict and validate structural performance.

• Qualification Support
  Prepare analysis reports and strength documentation to support verification, qualification, and safety activities.

• Design Optimisation
  Work closely with multidisciplinary engineering teams to improve designs, evaluate trade-offs, and enhance structural performance throughout the product lifecycle.

• Testing & Validation
  Analyse test results and structural failures to validate simulations and support design improvements.

• Documentation & Traceability
  Maintain clear and traceable records of structural analyses, engineering assumptions, requirements, and supporting documentation in line with company processes.

We Would Love You to Have

• Experience
  Previous experience in structural analysis, fatigue calculations, and mechanical design of metallic and composite structures, preferably in aerospace, UAV or space applications.

• Technical Expertise
  Proficiency with FEA and 3D CAD software (ANSYS, Nastran, SolidWorks etc), structural and fatigue analysis, and a strong theoretical understanding of structural mechanics. Familiarity with defence industry standards (MIL-STD, STANAG) is a plus.

• Soft Skills
  Proactive, solution-oriented mindset with exceptional communication skills. Delivery-focused, with the ability to manage multiple priorities and meet strict deadlines.

• Mission Alignment
  Strong alignment with our mission to build affordable and mass-manufacturable defence technologies — ensuring every euro spent moves us closer to our goal. 

• Security Clearance
  Willingness to undergo a background check as a condition of employment. 

• Open to Relocate
  Willingness to relocate to Tallinn.

Our Values

Our mission is ambitious, and it takes a team that works with the same intensity.

• Own the Mission: Mission first. Always.
  We choose impact — we focus on what moves the mission forward fastest instead of “nice-to-haves". We fix it now — when delays or problems appear, we step up, rally the right people, and solve them immediately. We keep momentum — when time matters, we stay focused and move forward without waiting for perfect conditions.

• Strive for More: Dare more. Do more. Achieve the impossible.
  We challenge the status quo — we question, test, and improve instead of accepting “the usual way.” We embrace discomfort — we step outside comfort zones and turn challenges into growth. We anticipate the future — we build solutions that scale and set higher standards each time.

• Build with Trust: Be open. Keep promises.
  We walk the talk — what we say, we do. No excuses, no exceptions. We share openly — we communicate clearly and early, even when the news is hard. We own outcomes — we admit errors quickly, fix them, and prevent them from repeating.
