We are seeking a  Control Engineer  to tackle all control-related challenges across the missile development portfolio, both at the system and sub-system level. In this role, you will architect, develop, and validate robust control solutions that enable autonomous flight, precision guidance, and reliable manoeuvrability while working closely with actuation, airframe, propulsion, and systems engineers.

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

• Design end-to-end control system architectures for the overall homing loop as well as sub-components that satisfy mission performance, reliability, and safety requirements.
• Synthesize and tune controllers using classical (PID, gain scheduling) and modern optimal/robust techniques (LQR, H∞, μ synthesis, inversion-based methods) to meet stringent autonomous flight specifications.
• Partner with actuation, airframe, propulsion, and electronics teams to ensure control laws are compatible with actuator bandwidth, structural dynamics, and sensor characteristics.
• Derive clear control system requirements and maintain configuration baselines throughout the product lifecycle.
• Contribute to the development and refinement of the underlying vehicle dynamics models that feed the control design process.

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.
