Responsibilities

Own the roadmap for AI applications that generate 3D geometry (STEP/Parasolid) and/or end-to-end PCB design from performance requirements and constraints

Lead development of automated loops between MCAD and ECAD agents and simulation agents (CFD, FEA, PIC, thermal, SI/PI, etc.), including meshing, solving, and post-processing

Embed manufacturability constraints (e.g., tool access, stock sizes, 5-axis machinability, additive manufacturing limits, via drilling constraints, etc.) into design checks and AI behavior

Develop and apply topology optimization and shape optimization workflows (or invent new generative methods) that output usable, production-ready geometry

Collaborate with propulsion, mechanical, electrical, and manufacturing engineers to validate AI-generated designs against test data and operational constraints

Mentor and guide more junior engineers and AI specialists working on mechanical, propulsion, electrical, and/or PCB applications

Partner with the Agentic Platform Lead to ensure application requirements inform platform capabilities and performance priorities

Champion an experimentation culture around simulation speedups, new physics models, and novel generative design workflows

Required

Master's degree + 5 years, or PhD + 3 years, in Mechanical or Aerospace Engineering, Computational Engineering, Electrical Engineering, Physics, or a related field; or equivalent practical experience

Experience designing and analyzing real hardware that flies or operates in demanding environments (propulsion, structures, mechanisms)

Strong programming skills in Python or C++, with experience automating CAD and CAE tools (e.g., SolidWorks, Creo, Ansys, COMSOL, Star-CCM+) or experience with ECAD tools (Altium, etc.)

Hands-on familiarity with CFD, FEA, SPICE, or related numerical simulation methods

Proven ability to lead cross-functional engineering projects and mentor junior engineers

Evidence of a 'builder' mindset: side projects, labs, or prior roles where you pushed tools, simulations, or hardware well beyond what was handed to you

Preferred

In-depth knowledge and experience across both PCB and mechanical design would make for the strongest candidates

Experience with topology optimization, shape optimization, or differentiable design workflows and ideas on new generative approaches that will push the boundaries of what is possible

Experience with auto-routing, automated schematic generation, or other automation approaches for electronics design

Practical experience with machining, 3D printing, or other fabrication techniques

Background in plasma physics, fluid dynamics, or thermodynamics as applied to propulsion

Experience working with AI or automation to accelerate CAD/CAE/EDA workflows

A personal history of building things for fun—rockets, race cars, robots, or any other kinetic or electrical systems
