Job summary

Saab UK in Bedford is seeking a UAV Design Engineer with aircraft sizing ownership to turn requirements into sized, analysable air vehicle concepts through rapid, iterative trade studies.

You will work within Saab UK’s Blue Bear unit, applying hands-on design, data-validation, and propulsion integration to deliver viable concepts while using OpenVSP, RCAIDE, AVL, and PX4/SITL tools. This role requires collaboration across a small multidisciplinary team.

Qualifications

• Aircraft sizing, concept-design tooling, and synthesis of flight-test data to improve models.
• Conceptual design and sizing, constraint analysis, weight and mission/energy sizing.
• Scripting and analysis using Python or similar for rapid iteration.

Responsibilities

• Perform aircraft conceptual sizing and constraint analysis to define feasible design points.
• Develop parametric air vehicle geometry and drive the analysis loop for rapid iteration.
• Synthesize flight-test and telemetry data to validate and calibrate models.
• Select and shape propulsion concepts and integrate into mission analyses.
• Maintain and improve the concept-design toolchain and automation.

Job description

early exploring design trade space and rapidly iterating through geometry, aerodynamics, weights, propulsion, mission and stability.

Key Responsibilities: Perform aircraft conceptual sizing and constraint analysis to define feasible design points for new UAV concepts. Develop parametric air vehicle geometry and Outer Mould Line and drive it through the analysis loop, regenerating a concept from a defined parameter set. Produce the core conceptual outputs. Run trade studies and design-space exploration. Synthesise flight-test and bench-test data (flight logs, telemetry, measured aero/propulsion performance) and use it to validate, calibrate and improve conceptual models and sizing methods. Select and shape propulsion system concepts and integrate them into mission and energy-network performance analysis. Maintain, improve and where appropriate build the concept-design toolchain and automation that underpins rapid iteration (geometry, aero, mission, surrogate and data-processing tools).

Capture and communicate design risk, where the design is immature or sensitive and feed it into the programme risk register.

Qualifications and skills

• Aircraft sizing, concept-design tooling, and the synthesis of flight-test data to improve models
• Aircraft / UAV conceptual design and sizing, constraint analysis, weight and mission/energy sizing, and closing a design point.
• Hands-on experience with conceptual and preliminary design tools such as OpenVSP, RCAIDE, AVL, XFLR5, Datcom or equivalent in-house tools.
• Sound applied aerodynamics knowledge.
• Experience synthesising flight logs / telemetry / test data and using it to validate and improve analytical models (model calibration, correlation to test).
• Strong scripting and analysis skills in Python (or similar).
• Working understanding of the full conceptual design loop: geometry, aerodynamics, weights, propulsion, mission performance and stability & control, and how the disciplines couple.
• Strong problem-solving skills, sound engineering judgement, and a proactive approach to improving methods and tools.
• Ability to work collaboratively across a small, multidisciplinary engineering team.
• Stability & control analysis, flight dynamics modelling, and handling-qualities assessment.
• Experience with PX4 / ArduPilot, SITL/HITL simulation, and processing autopilot flight logs (ULog, MAVLink).
• CAD and geometry handling; exporting/meshing surfaces for higher-fidelity aero (panel/CFD).
• Mid- to high-fidelity aero exposure (panel methods such as FlightStream, or RANS CFD) for validating key design points.
• Experience working in safety-critical, regulated or defence environments.
• Ability to gain SC Clearance.
