Dexterity's Foresight World Model powers real-time perception, planning, and execution across physical environments with the interpretability required for industrial deployment. Dexterity is headquartered in Redwood City, California.\nDexterity is backed by world-class investors such as Kleiner Perkins, Lightspeed Venture Partners, and Obvious Ventures. We are a diverse and multidisciplinary team with a culture built on passion, trust, and dedication.\nAbout the Role\nLead functional safety engineering for industrial robots, autonomous mobile systems, and motion-control and drivetrain architectures. Own the full safety lifecycle - from hazard and risk analysis through requirements, architecture, implementation, verification, and validation - to support compliant deployment in North American, European, and Japanese markets.\nResponsibilities\n- Create and maintain a Functional Safety Management Plan. Lifecycle, responsibilities, required work products, competence and independence requirements, and approval authority.\n- Develop and maintain Quality Management System (QMS) integration. Define how safety activities, reviews, approvals, deviations, corrective actions, and audits run within the existing quality processes.\n- Perform machinery risk assessments per ISO 12100; identify hazards, define safe states and safety functions, and determine required Performance Level (PLr) or Safety Integrity Level (SIL).\n- Support compliance and certification activities with certification bodies, test laboratories, and external assessors, including UL, TÜV, NRTLs, notified bodies, and other relevant organizations.\n- Interpret relevant regulations and standards, advise engineering teams on their practical application, and maintain awareness of changing robotics-safety and compliance expectations\n- Develop and review safety architectures for E-stop, protective stop, Safe Torque Off (STO), safe stopping, safely limited speed, overspeed protection, brake control, restart prevention, and protective sensing.\n- Apply ISO 13849-1/-2 and IEC 62061, including redundancy, diagnostics, MTTFd/PFH calculations, common-cause failure analysis, and validation.\n- Analyze robotic and drivetrain failure modes, including motor and inverter faults, welded switching devices, encoder or feedback loss, brake, steering, and gearbox failures, unintended torque, overspeed, and loss of control.\n- Define safety interfaces among safety PLCs, robot controllers, servo drives and inverters, motors, brakes, encoders, scanners, contactors, and safety I/O; specify safe behavior for communication loss or invalid data.\n- Apply safety-rated communication protocols such as PROFIsafe, CIP Safety, and EtherCAT/FSoE, with working knowledge of PROFINET, EtherNet/IP, and other industrial networks as system interfaces.\n- Perform HARA, FMEA/FMECA/FMEDA/DFMEA, fault tree analysis (FTA), fault injection testing, and safety-case analyses; translate results into traceable safety requirements and design evidence.\n- Perform mechanical and structural analysis. Failure analysis for components whose failure can create or worsen a hazard, linked to inspection and proof-test needs.\n- Plan and execute verification and validation activities covering stopping performance, response time, sensor and encoder faults, drive faults, communication loss, restart behavior, and achievement of the defined safe state.\n- Support safety-related PLC and embedded implementation, component selection, IEC 61131-3 programming, customer-site standard operating procedures, and scalable safety training and troubleshooting.\n- Engage in customer-facing technical meetings to clarify safety design decisions, explain FuSa compliance, and provide expert guidance on system guardrails\nRegulatory requirements\n- ISO 12100 - Machinery risk assessment and risk reduction.\n- ISO 13849-1/-2 - Safety-related parts of control systems: design principles and validation.\n- IEC 61508 - foundational, cross-industry functional-safety standard for electrical, electronic, and programmable electronic safety-related systems.\n- IEC 62061 - Functional safety of machinery control systems; IEC 61508 - Functional safety of electrical/electronic/programmable electronic (E/E/PE) systems, where applicable.\n- IEC 60204-1 / NFPA 79 - Electrical equipment of machinery.\n- ISO 10218-1/-2 and ANSI/RIA R15.06 - Industrial robot and robot system safety requirements.\n- ANSI/RIA R15.08 and ISO 3691-4 - Industrial mobile robot and driverless industrial truck safety; ANSI/ITSDF B56.5, where applicable.\n- IEC 61496 - Electro-sensitive protective equipment; UL 1740 and UL 3100, where applicable.\n- Applicable market requirements, including the EU Machinery Regulation and EMC requirements, plus North American certification requirements\nQualifications Required\n- Bachelor's degree in Electrical, Mechanical, or a related engineering discipline.\n- 10+ years of functional safety experience in robotics, autonomous systems, industrial automation, automotive, aerospace, or other safety-critical machinery domains.\n- Hands-on experience with servo drives, inverters, motor controls, encoders, brakes, safety PLCs, safety I/O, and safety-rated networks.\n- Demonstrated ownership of the complete safety lifecycle: hazard and risk analysis → safety requirements → PLr/SIL determination → architecture → implementation → verification → validation.\n- Ability to evaluate manipulator and mobile-platform/drivetrain hazards, including stopping distance, stored energy, braking, unintended motion, and loss of control.\n- Experience with Structured Text, Ladder Logic, and/or Function Block Diagram, along with PLCs, microcontrollers, and safety-related embedded systems.\n- Functional safety certification such as TÜV Functional Safety Engineer, CFSE, CFSP, or CMSE preferred.\nCandidates must be able to determine how a safety-critical failure is detected, how the system reaches a defined safe state, and how the required PL/SIL is quantitatively justified and demonstrated through analysis, implementation, and validation.\nWhat Makes You Successful\n- Strong independent ownership, cross-functional communication, and the ability to convey technical safety decisions to engineering leadership and non-technical stakeholders.\n- Ability to develop clear compliance documentation, safety procedures, and customer-facing technical guidance.\n- Willingness to travel domestically and internationally as required.","description_format":"text","description_chars":6848,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics
