Senior Electrical Engineer - Embedded Systems & Product Development

About Bots UnlimitedBots 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 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 senseof 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 the right fit for you!About The RoleWe are seeking a Senior Electrical Engineer with deep experience in embedded systems and product development to join our fast paced, high accountability team. This role goes beyond circuit board design - you will drive the architecture, integration, and validation of complex electronics in high performance compute modules, communications systems, and robotics products. This role is critical to the design, development, and productization of compute modules, RF systems, camera systems, and BLDC motor controllers.You must be a Type-A personality who thrives in fast-paced environments, is self-managed, documents rigorously, and drives designs through manufacturing. This is not just a circuit designer role; you will help lead the entire electrical product lifecycle, including reviews, simulations, integration, and support through production.Key ResponsibilitiesLead the electrical design of complex multi-layer HDI PCBs, compute modules, and custom edge AI platformsPerform detailed power delivery network (PDN) analysis, transient analysis, and high-speed signal integrity simulationDrive and manage design reviews (initial, intermediate, and final), documenting all design decisions and review outcomes in ConfluenceOwn the full product development lifecycle from schematic capture to production releaseSelect, validate, and integrate ICs, power systems, sensors, radios, and other componentsCollaborate closely with mechanical engineers to ensure seamless integration into enclosures, thermals, shielding, and interconnectsDevelop validation plans, bring-up guides, and work with firmware/software teams during prototype and EVT/DVT phasesWork within KiCad as the primary ECAD tool; Altium experience is helpful but not requiredMaintain clean revision control, documentation, and BOMs across development and productionAuthor thorough documentation in Confluence: schematics, reviews, test plans, bring up notes, etcInterface directly with suppliers and fabrication/assembly partners on production readinessDrive validation and bring up of new hardware platforms, working closely with firmware and test teamsProactively manage project scope, priorities, and deliverables with minimal oversightServe as the primary electrical point of contact for external manufacturers and suppliers, supporting hardware bring-up, first article builds, and sustaining engineering tasksDevelop per-unit electrical test plans and oversee the design and validation of custom test fixtures for production environments, ensuring repeatable and scalable test coverageSupport customers through hands-on electrical integration of our modules into their systems, including design reviews, bring-up assistance, and technical validation to ensure successful adoption of development kits into production designsTravel: Willingness to travel periodically throughout the year to support key product milestones and collaboration efforts. Examples include visiting manufacturing partners for first article builds, production testing, and process improvements; traveling to design partners for technical alignment or strategy meetings; and attending select trade shows or industry events to support product demonstrations or team visibilityRequirementsRequired QualificationsB.S. or M.S. in Electrical Engineering or equivalent technical discipline6+ years experience in electrical product development, including shipping real productsExpert in KiCad (mandatory), with working knowledge of Altium or similar toolsDemonstrated experience with HDI board design, controlled impedance, microvias, blind/buried viasExperience with PoP (package on package), DDR memory routing, and high-speed interfaces (PCIe, USB 3, etc.)Strong skills in PDN, SI, and EMI analysisExperience integrating PCBs into mechanical systems (e.g. stackups, grounding/shielding, mounting, thermal)Fluent in Confluence, Git, and structured engineering documentation practicesProven track record of managing full product lifecycles from concept to productionStrong DFM/DFT understanding and supplier/CM collaborationProficiency in power systems design, regulators, battery management, and protection circuitsProficiency with soldering irons, hot air rework, multimeters, power supplies, and other common lab equipmentComfortable with fine-pitch rework, jumper wiring, and component replacement on dense PCB layoutsAbility to interpret schematics and translate debug results into actionable hardware changesFamiliarity with firmware bring up tools, test instruments (oscilloscopes, logic analyzers), and embedded Linux platformsHands-on experience collaborating with contract manufacturers or EMS partners through the entire product lifecycle, from prototyping to production rampStrong understanding of production test strategy, including fixture design, validation, and documentation for factory deploymentProven experience working directly with customers or OEMs to support hardware or module integration, including reviewing schematics, layout, and test plans as part of the pre-sales and design-in processFamiliarity with product regulatory and compliance factors (FCC/CE/UL desirable)High ownership mentality - must be self managed, organized, and quality obsessedPreferred / Bonus QualificationsExperience working in a startup or fast-paced product company environmentPrior experience in RF system design, antenna tuning, or wireless regulatory compliance testing (FCC/ISED/CE)Familiarity with wireless communication modules including Wi-Fi, Bluetooth, or 5GExperience designing with high-power or high-current motor controllers (BLDC, ESCs)Hands-on experience with EMC/ESD mitigation techniques and compliance testingProficiency in Python or Bash for test automation or bring-up scriptingExperience in troubleshooting embedded Linux systems and navigating Linux terminalsBenefitsWhy Join UsHigh-Impact Work: Be a core contributor to the development of real products that ship to customers in the robotics and UAS sectorsFast-Paced Environment: Work at startup speed in a self-managed, execution-driven culture with a high degree of ownership and trustTechnical Excellence: Collaborate with experts across electrical, mechanical, and software domains building next-generation compute and comms modulesFlexibility: This role supports hybrid, remote, or onsite in San Antonio depending on your preferenceReal-World Exposure: Travel opportunities to manufacturers, design partners, and industry events, see your work in action from bench to mass manufactured productCustomer-Centric Engineering: Work directly with customers and OEMs to drive real-world adoption and integration of your designsWork EnvironmentThis role is flexible and can be hybrid, onsite in San Antonio, or remote, depending on the candidate's profile.
