## About Harmattan AI

Coordinated Saturation at the Edge

## About the role

##### About Us

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.

Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.

##### About the Role

As a Simulation / Mechanical Analysis Engineer on Harmattan AI's Airframe team, you will be the reference for structural, vibration and impact simulation. Your mission is to replace our current trial-and-error loop with a predictive, simulation-driven approach: model the dynamic behaviour of our carbon / plastic / aluminium assemblies, pinpoint the critical zones, and guide design changes **before** we build and fly. You will also build the tools, templates and methodology that allow the rest of the team to run reliable first-order analyses autonomously. This is primarily a simulation role, with a meaningful share of hands-on design to implement and validate your own recommendations.

####

##### Responsibilities

- Carbon chassis analysis & optimisation: Analyse and optimise carbon chassis (priority: quadcopter platforms) — stiffness, mass, resonance — and act as a performance safeguard to prevent regressions across projects.

- Modal & vibration analysis: Perform modal (eigenfrequency) and harmonic/random vibration analyses on carbon-composite, plastic and aluminium assemblies to identify natural frequencies, mode shapes and resonance risks relative to operating excitations (motors, props, flight loads).

- Crash / shock & impact analysis: Perform dynamic / explicit simulations of crash, shock and impact events (drop tests, crash and impact scenarios) on composite and metallic structures — predicting deformation, damage and failure, and defining design changes to improve survivability and qualify structural limits.

- Structural FEA: Run static, stiffness, fatigue and failure analyses to support design decisions and de-risk new concepts early.

- Composite materials & failure: Apply solid knowledge of composite materials (carbon laminates, anisotropy, delamination and damage/failure criteria) to model both quasi-static and impact behaviour realistically.

- Carbon-composite modelling: Build representative models of laminated / pultruded carbon structures (ply orientation, anisotropy, bonded and bolted joints) and correlate them against physical tests.

- Test correlation: Define and run validation tests (modal hammer / accelerometers / shaker, drop / impact tests, flight data) and correlate simulation vs. measurement to continuously improve model fidelity.

- Design-to-target: Translate simulation results into concrete design changes (geometry, stiffeners, material, joints) and implement part of them yourself in CAD; iterate with the design owners.

- Tooling & methodology: Develop reusable tools, scripts, templates and calculation sheets so the team can run first-order modal/structural checks autonomously, and document the simulation methodology as the team's source of truth.

- Cross-functional work: Collaborate with the design, electronics and industrialisation teams to feed simulation insight into the product, and maintain documentation on Confluence.

##### Candidate Requirements

- Master's degree in Mechanical / Aerospace Engineering, Structural Mechanics, or a related field.

- Proven experience in FEA, with a strong focus on modal / vibration / dynamic analysis (e.g., Ansys, Abaqus, Nastran, OptiStruct, COMSOL, or similar).

- Solid grounding in structural dynamics and vibration theory (natural frequencies, mode shapes, damping, resonance, FRF).

- Experience in crash / shock / impact simulation (explicit dynamics — e.g. Ansys LS-DYNA, Abaqus/Explicit, Radioss or similar) for drop-test, crash and impact scenarios, including strain-rate and failure modelling.

- Strong knowledge of composite materials (carbon-fibre laminates, anisotropy, layups, joints, and damage / delamination / failure criteria), applied to both vibration and impact behaviour.

- Ability to correlate simulation with physical testing (modal testing, accelerometers, shaker, drop / impact tests, flight data) and judge model validity critically — not just trust the solver output.

- Working proficiency in CAD (SolidWorks preferred) to implement and adjust designs based on analysis.

- Scripting / automation skills (Python, MATLAB, or APDL) to build tools and parametric studies for the team.

- Rigour, ownership and clear documentation habits; able to challenge results and explain them simply to non-specialists.

- Full commitment to Harmattan AI's mission, vision, and growth plans.We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
