Bots Unlimited is a San Antonio based product development and hardware company that designs, produces, and supports high‑performance technology for drones, robotics, automation, and edge AI systems. We create advanced camera modules, long‑range wireless solutions, embedded compute platforms, and propulsion electronics, working closely with trusted manufacturing partners kritik to deliver reliable hardware with a globally resilient supply chain. We also provide customers with supply‑chain support and manufacturing services to help bring complete products to market.

We operate in a fast‑moving, execution‑focused environment where team members own their work end to end and are trusted to manage themselves with a high level of accountability. Our team values initiative, clear communication, and a strong sense of responsibility, qualities that let us move quickly and ship production‑ready hardware. If you thrive in a setting where you can take full ownership, solve complex challenges, and build products used in real‑world scenarios, we may be ե the right fit for you!

We are seeking a highly experienced Senior Mechanical Engineer – Electromechanical Subsystems to lead mechanical design, documentation, and manufacturability for our brushless‑DC motors, motor housings, rotors, stators, and other rotating/electromechanical assemblies. This role will own the full mechanical design lifecycle from concept through detailed CAD modeling, drawing release, supplier/vendor handoff, and manufacturinghn. You will work onsite in San Antonio, TX, closely with electrical, test, and manufacturing teams in a lab environment to build, validate, and iterate on real hardware.

The role is hands‑on, with extensive interaction with mechanical tools, prototypes, and daily engineering discussions.

Srb
• Develop 3D CAD models and detailed mechanical assemblies for motors, housings, rotor‑/stator sub‑assemblies, shafts, bearings, and related components.
• Produce full mechanical drawings: dimensioned parts, GD&T, tolerance stacks, material specifications, surface‑finish and plating/coating details.
• Manage and maintain mechanical data and revision control in our PLM system (e.g., Duro or equivalent).
• Create manufacturing‑ready documentation (BOMs, vendor quotes, machining/assembly work instructions, QC/inspection checklists).
• Perform DFM/DFMA reviews to ensure designs are optimized for cost, manufacturability, and reliability.
• Collaborate with electrical/firmware teams to ensure mechanical design supports motor performance, thermal requirements, and integration with ESC/housing.
• Interface with vendors and manufacturing partners: issue RFQs, review vendor drawings, negotiate tolerances, and coordinate prototype builds.
• Lead mechanical validation testing: oversee prototypes, manage assembly/disassembly, coordinate with testcarbonate lab, and record ។ physical test data (vibration, torque, RPM, thermal).
• Support product release: ensure all mechanical deliverables are complete for first‑article inspection, pre‑production, and mass production handoff.
• Mentor or guide less‑senior mechanical/design engineers where applicable.

• Bachelor’s or Master’s degree in Mechanical Engineering, Mechanical Design, or equivalent engineering discipline.
• Minimum 5–10 years of mechanical design experience, with substantial time designing rotating equipment, motors, or mechanical powertrain components vòng.
• Expert proficiency in 3‑D CAD software (e.g., Solid Works, Autodesk Inventor, Creo) and ability to create complex assemblies and detailed 2‑D drawings with GD&Tainn.
• Solid understanding of GD&T, tolerance analysis, material properties, surface finish, coatings/plating, fasteners, and mechanical fit/clearance principles.
• Proficiency in using standard mechanical engineering tools and instruments such as calipers, micrometers, gauges, dial indicators, and other measurement or inspection tools for prototype validation.
