We specialize in building and operating advanced test ranges for low Technology Readiness Level (TRL) single- or dual- use autonomous platforms, providing a critical bridge between early-stage innovation and real-world mission requirements.\nOur ranges are designed to replicate complex, contested, and dynamic environments-giving innovators, researchers, and defense partners the ability to validate, stress-test, and mature their systems with speed and rigor. By combining deep technical expertise with a strong national security ethos, Anno.ai ensures that emerging autonomous technologies are tested not only for performance, but for resilience, adaptability, and operational relevance.\nAnno.ai is a growing company with a team drawn from diverse professional backgrounds, bringing together expertise in defense, technology, engineering, and operations. We intentionally build our teams on the foundation of trust. Our values including the trust rule, ownership, bias for action, never stop learning, and sustainable excellence, not only guide how we work internally, but also how we partner with customers and stakeholders.\nAt Anno.ai, we believe that mission success depends on empowering innovation at the edge. We exist to help our partners move faster, fail smarter, and ultimately deliver autonomous capabilities that safeguard both national security and the future of global stability.\nDisclaimer: Due to the sensitive nature of our engineering work, Anno.Ai enforces strict digital footprint and identity verification. We actively monitor for synthetic profiles, proxy networks, and AI interview assistants; any fraudulent activity will result in immediate disqualification.\nPosition Overview \nAs a Senior Mechanical Engineer at Anno.Ai, you will design, develop, prototype, document, test, and support manufacturing of systems used in field-deployable autonomous, sensor, and mission-support platforms. You will create 3D models, mechanical drawings, schematics, fixtures, mounts, enclosures, and components that enable rugged, reliable operation in demanding field environments. \nYou will work directly with product, manufacturing, and field operations teams to develop designs that support integrated systems and components. This role requires a hands-on engineer who can move quickly from concept to CAD to prototype to manufacturable hardware while balancing performance, durability, weight, cost, serviceability, and operational constraints. \nFor this opportunity we are looking for engineers who have experience designing rugged mechanical systems, enclosures, mounts, and field-ready hardware. Experience with additive manufacturing, rapid prototyping, environmental hardening, pressure testing, weather-resistant materials, manufacturing support, and military-standard design considerations is ideal. Annomals are practical, mission-driven, and fun. We value good management, your career growth, and ethical, responsible practices. \nThe ideal candidate for this role would reside in Minnesota. \nCandidates need to be able to obtain and maintain U.S. Government security clearance (U.S. citizenship required). Candidates must be able to travel up to 20% of the time. \nWhat You Will Do\nDesign rugged mechanical systems, enclosures, mounts, fixtures, and sensor housings\nSupport products and related test range systems\nCreate 3D CAD models, drawings, assemblies, and BOM inputs\nPrototype, fabricate, assemble, and iterate on field-deployable hardware\nDesign for weather resistance, vibration, shock, corrosion, and thermal performance\nDevelop mechanical interfaces for sensors, electronics, cabling, and other infrastructure\nSupport manufacturing, design reviews, fit checks, and documentation updates\nTroubleshoot hardware issues during prototype builds and field testing, and field support\nCollaborate with other cross-functional teams\nRequired Qualifications \nBachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a relatedtechnical field\n5+ years of professional experience designing mechanical systems, enclosures, mounts, fixtures, rugged hardware, sensor payloads, or field-deployable equipment\nStrong proficiencywith 3D CAD tools such as SolidWorks, Autodesk Fusion, or similar software, including production-quality mechanical drawing practices\nExperience with tolerance stack-ups, GD&T, revision control, design reviews, and manufacturable documentation\nExperience designing serviceable components for field-deployable hardware\n\nExperience supporting additive manufacturing, rapid prototyping, prototype fabrication, and design iteration from early concepts through functional test articles\nExperience supporting manufacturing processes such as CNC machining, sheet metal fabrication, additive manufacturing, composites, injection molding, casting, or low-rate production builds\nExperience with environmental design considerations including sealing, water resistance, corrosion resistance, vibration, shock, thermal management, UV exposure, and weatherization\nAbility to read and interpret technical documentation, schematics, layout files, BOMs, technical orders, and mechanical drawings\nAbility to obtain and maintain U.S. Government security clearance (U.S. citizenship required)\nAbility to travel up to 20%\nPreferred Qualifications \nPrior experience supporting UAS/cUAS systems, defense or aerospace industry\nExperience designing for extreme environments\nExperience with maritime, coastal, buoy-mounted, vehicle-mounted, or other outdoor systems exposed to moisture, salt air, pressure, wind, temperature variation, and long-duration field operation\nExperience with MIL-STD-style environmental hardening, ruggedization, shock/vibration design, ingress protection, corrosion control, or field qualification testing\nExperience with additive manufacturing \nTotal Rewards Package for Our US Employees \nCompetitive salary\nEquity\nComprehensive benefits package\n401k with a 5% company match\nPaid holidays and generous paid time off offering\nPaid leave programs\nPatent bonus program\nEmployee referral bonus program\nLearning and development program\nOpportunity to work with a team of highly skilled, creative and motivated team members\nQuick Note on Role Fit\nIf you think you have what it takes to fulfill this opportunity, but don't necessarily check every box, please still connect with us at .
