Mechanical Architect

About the Role

We are looking for a Mechanical Architect to support the development of next-generation defence systems through system-level mechanical design and engineering delivery. In this role, you will help mature mechanical concepts, interfaces and requirements, working closely with multidisciplinary teams to deliver robust, producible and 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 develop, industrialise and deliver advanced defence systems. If you thrive on innovation, ownership and impact — we want to hear from you.

Key Responsibilities

• System-Level Mechanical Design
  Develop and evaluate mechanical concepts at system and subsystem level, supporting the definition of product architecture, mechanical interfaces, constraints and requirements.

• Trade Studies & Technical Decision-Making
  Support trade studies, design reviews and engineering decisions across the product lifecycle, helping teams balance performance, mass, manufacturability, reliability, safety and cost.

• Design Delivery
  Lead and deliver mechanical design work packages from concept generation through detailed design to final delivery, ensuring timely progress in a demanding development environment.

• Production Readiness
  Apply robust design methods and practical engineering judgement to improve product quality, manufacturability and readiness for scalable production.

• Supplier & Partner Engagement
  Work with suppliers, external partners and internal teams to develop practical, scalable engineering solutions.

• Risk, Documentation & Traceability
  Identify technical risks, manage priorities, support rapid problem-solving, and maintain clear records of assumptions, requirements, decisions and design maturity in line with industry best practice.

We Would Love You to Have

• Educational Background
  Higher degree in Mechanical Engineering, Aerospace Engineering or a related discipline.

• Experience
  5+ years of experience delivering mechanical design work packages within complex, multidisciplinary engineering programmes, preferably in aerospace, UAV, space or defence applications.

• Technical Skills
  Confident use of 3D CAD and engineering design tools, with strong experience across the full product lifecycle. Understanding of structural, thermal and/or dynamic behaviour is advantageous.

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

• 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 Travel or Relocate

  Willingness to travel occasionally within Europe as required by the role, and ideally openness to relocating 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.
