Mechanical Integration Engineer

ABOUT US: Astro Mechanica is a vertically integrated aerospace company building a faster, more connected future. Our mission is to democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable. We believe that rapid, on-demand, point-to-point global mobility will become the new standard for moving people and goods across the planet. To achieve this, we are integrating our advanced airframe and engine technologies—which include Duality™, our proprietary dual-use propulsion system—with a new flight operations model to make supersonic transport as efficient and economical as commercial air travel is today. In the near term, we are developing adaptable, high-speed systems to close aircraft performance gaps for the United States government. WHO WE ARE: We’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy. WHO YOU ARE You are an integration-minded engineer who thrives at the aircraft level and enjoys owning technically ambiguous problems from concept through test. You’re comfortable operating across disciplines—structures, propulsion, avionics, and flight sciences—and you care deeply about building tools, processes, and analyses that teams actually rely on. You take pride in creating clarity out of complexity: turning incomplete inputs into credible models, turning evolving designs into defensible mass properties, and turning program milestones into well-run technical gate reviews. You’re equally comfortable working in spreadsheets, code, and design reviews—and you enjoy being close to the hardware. WHAT YOU’LL DO: - Lead the development, maintenance, and automation of weight & balance tools, ensuring accuracy, traceability, and usability across the program - Own mass properties tracking, prediction, and reporting throughout design, build, and test, serving as a source of truth, interfacing with Teamcenter PLM and inventory management tools - Manage mechanical design guidelines that ensure common design practices across the structures, systems, and avionics teams. Downselect, document, and enable CAD and design practices - Manage standard materials selections, standard hardware selections, and standard design element selection by identifying designs that meet requirements and availability, validating designs through test, and ensuring the design team has CAD tools for setting usage. - Support structural layout and configuration development with guidance from senior engineers - Collaborate closely with design, manufacturing, and test teams to resolve system-level tradeoffs and integration challenges - Support systems integration and packaging efforts, including system space reservations, clash resolution, and aircraft-level mounting and arrangement concepts - Participate in design reviews, manufacturing support, and testing activities WHAT WE’RE LOOKING FOR: - 2–7 years of experience in aerospace mechanical engineering, aircraft design, or a closely related field - Strong understanding of mass properties and aircraft mechanical design - Experience building or owning engineering tools used for analysis and decision-making - Ability to lead technical efforts independently while collaborating effectively across disciplines - Clear communicator who can drive alignment in design reviews and program milestones - Flexibility to work in a fast-paced environment - Hands-on mindset with a bias toward execution and continuous improvement - Experience with systems integration, packaging, or aircraft layout - Exposure to certification, conformance, or government aerospace programs - Programming experience (Python, MATLAB, etc.) for analysis and tool automation - CAD and PLM experience (NX, CATIA, Creo, Teamcenter, 3DX, Windchill, etc.) PERKS & BENEFITS: - Comprehensive medical, dent
