Senior Safety Engineer (Humanoid Robotics)

Location: Palo Alto, United States; on-site

Company

hirify.global is developing Physical AI and humanoid robots for real-world industrial deployment on factory floors.

What you will do

• Own the functional safety lifecycle for a humanoid platform, including hazard analysis, risk assessment, SIL/PL determination, safety requirements, and validation.
• Design safety architectures for emergency stops, safety-rated monitored stops, power and force limiting, and speed and separation monitoring.
• Select and justify safety-rated controllers, sensors, contactors, and equivalent alternatives where standard components do not fit.
• Lead safety certification efforts and own the technical file and technical narrative presented to assessors.
• Collaborate with mechanical, electrical, controls, and AI engineering teams to integrate safety into the platform design.
• Build test fixtures, procedures, and evidence to validate safety claims and track evolving humanoid-robot standards.

Requirements

• 5–10 years of safety engineering experience with industrial robots, collaborative robots, AGVs/AMRs, or comparable machinery.
• Deep working knowledge of ISO 13849, IEC 62061, IEC 61508, and ISO 10218 or ANSI/RIA R15.06; familiarity with ISO/TS 15066.
• Software safety experience under IEC 61508-3 in addition to systems-level safety engineering.
• Hands-on experience owning product safety certification, including defending the technical approach to assessors.
• Experience with FMEA, FTA, HAZOP, and STPA, with sound judgment in selecting the appropriate method.
• Strong communication skills for explaining safety tradeoffs to executives, engineers, and external assessors.

Culture & Benefits

• Hands-on engineering focused on applying Physical AI to the physical world.
• Ownership of difficult, open-ended safety problems in dynamically balancing humanoid systems.
• Cross-functional collaboration across hardware, controls, AI, and mechanical and electrical engineering.
