Archer is an aerospace company building all-electric vertical takeoff and landing (eVTOL) aircraft designed to carry four passengers with minimal noise, advancing sustainable air mobility. This role owns the complete thermal system design for Archer's hybrid-electric aircraft platform. You will lead the design, modeling, and delivery of a novel thermal management system for hybrid aircraft. Key responsibilities include selecting appropriate technologies and materials for this complex system, optimizing for weight, performance, and cost-effectiveness. You'll define and execute comprehensive testing strategies to validate system performance, manage the full design lifecycle from concept through manufacturing and test phases, and interface with cross-functional teams including manufacturing, quality, stress analysis, and FEA engineers. You'll present technical designs to stakeholders, communicate complex thermal and mechanical rationale to multidisciplinary teams, and work independently to drive technical initiatives forward. The role requires strong fundamentals in complex system design, hands-on experience with mechanical design tools (Siemens NX), stress analysis, and finite element analysis. You'll also need proficiency in PDM/PLM environments and the ability to write comprehensive technical documentation. Ideal candidates bring 5+ years of mechanical design experience and a degree (BS/MS/PhD) in engineering or a related scientific field. Nice-to-have qualifications include prior experience with hybrid-electric aircraft, turbogenerators, eVTOLs, or hybrid automotive powertrains; familiarity with FAA or EASA certification processes; and knowledge of simulation model validation and uncertainty quantification methods.
