Non‑negotiables for this role

• 3+ years hands-on programming of SICK safety controllers using SICK Safety Designer (professional, production use).
• Electrical Engineering background with strong hands-on commissioning / troubleshooting on real vehicles.
• Confident Python programming and ability to read and debug existing Python code (integration of safety system with application logic).

About Navflex

Navflex builds autonomous mobile robots (AMRs) that operate in real warehouse and dock environments where safety, uptime, and reliability are mission-critical. Our robots must perform safely around people, forklifts, and mixed traffic while delivering measurable efficiency improvements for customers.

Role Overview

As our Senior Functional Safety & Safety Controls Engineer, you will own the end-to-end safety implementation on our mobile robotic platforms — from safety concept and risk assessment through hands-on implementation in SICK safety controllers and validation on the vehicle. You will work on the robot every day, iterate quickly, and ensure our safety behavior remains correct as platforms, sensors, and use cases evolve.

This role is highly hands-on and combines functional safety engineering with real-world safety controller programming and software integration. You will collaborate closely with robotics software (navigation/perception/control), electrical and mechanical engineering, and field operations to deliver safety solutions that scale across platforms and deployments.

What You Will Own

• Safety controller architecture and implementation across Navflex AMR/AGV platforms, with a strong focus on SICK safety controllers.
• Day-to-day development, commissioning, troubleshooting, and versioned configuration management of SICK Safety Designer projects.
• Safety integration points between the safety controller and the robot application stack (status, modes, field switching, diagnostics), including Python-based tooling/software components.
• Safety verification and validation on the vehicle, including test planning, execution, evidence capture, and documentation maintenance.
• Support for certifications, audits, and customer/site acceptance related to machinery safety and mobile robot standards (e.g., ISO 3691-4, ISO 13849).

Key Responsibilities

Safety concept, risk assessment, and requirements

• Lead and continuously maintain risk assessments for our vehicles and operating modes (e.g., autonomous, manual, service/maintenance) and derive safety requirements and safety functions.
• Translate safety requirements into an implementable safety concept and safety controller design, including safety I/O definitions, sensor coverage strategy, and safe-state behavior.
• Define required Performance Levels (PLr) / SIL targets for safety functions and maintain traceability from hazards safety requirements implementation verification evidence.

SICK safety controller programming (SICK Safety Designer)

• Design, implement, and maintain safety logic in SICK safety controllers using SICK Safety Designer, including diagnostics and safe-state handling.
• Commission and troubleshoot safety systems on real robots: wiring verification, signal integrity, scanner/encoder configuration, safety I/O checks, and fault analysis.
• Build a maintainable configuration strategy across product variants: reusable modules, clear naming conventions, version control, and release/deployment procedures for safety configurations.
• Implement and validate common AMR/AGV safety behaviors such as emergency stop, protective stop, speed reduction, safe direction, safe speed monitoring, and field set switching (as applicable to the platform).
