Locus Robotics is seeking a Site Reliability Engineer (SRE) with a specialized focus on Remote Device Management. As a core member of our reliability team, you will ensure the stability, security, and scalability of the LocusONE platform supporting our growing fleet of Autonomous Mobile Robots (AMRs), peripherals, and reporting devices. You will bridge the gap between software development and field operations, using Linux expertise and Mobile Device Management (MDM) tools to manage thousands of edge devices globally. This is a remote role.

• Fleet Management at Scale: Design, implement, and maintain robust and secure device management strategies for remote devices using Unified Endpoint Management (UEM), MDM solutions, and orchestration tools.
• Reliability & Monitoring: Develop and manage observability pipelines to track device health, connectivity, and performance metrics across diverse warehouse environments.
• OTA & Lifecycle Management: Own the end-to-end lifecycle of device software, including secure Over-the-Air (OTA) firmware updates, rollback strategies, and OS hardening.
• Incident Response: Participate in on-call rotations to troubleshoot complex system failures, performing root cause analysis (RCA) to drive long-term reliability improvements.
• Self-Healing Infrastructure: Develop automated remediation scripts that detect and fix common edge issues such as hung scanning processes or display driver freezes without manual intervention.
• Zero-Touch Scalability: Architect and maintain remote provisioning and management workflows for a global fleet of Linux, iPads, and Android devices using secure remote management strategies.
• Secure Remote Access: Implement and manage secure remote access protocols such as SSH, VPNs, and private APNs to enable out-of-band troubleshooting and real-time device control without physical site visits.
• SLO/SLI Frameworks: Define and enforce Service Level Objectives (SLOs) and Service Level Indicators (SLIs) for device availability, connectivity, and peripheral performance.
• Error Budget Management: Use error budgets to balance the pace of innovation with fleet reliability, ensuring data-driven decisions for feature releases versus stability fixes.
• Security Governance: Align fleet operations with industry standards such as the NIST Cybersecurity Framework (CSF), ISO/IEC 27001, and CIS Controls.
• Vulnerability Management: Drive continuous monitoring and automated patching schedules to mitigate risks and ensure regulatory compliance across all managed device platforms.

• Master’s degree in Computer Science, Software Engineering, Systems Engineering, Robotics, or equivalent experience.
• 7+ years of experience: Proven track record in SRE, DevOps, or Systems Engineering with a focus on IoT, remote devices, or distributed edge hardware.
• Deep proficiency in Linux/Unix systems (Debian/Ubuntu preferred), including kernel tuning, shell scripting (Python, Bash), and networking protocols (TCP/IP, MQTT, CoAP, HTTPS/REST, DNS).
• Knowledge of security best practices for IoT and remote devices, including secure boot, encryption at rest/in transit, and certificate management.
• Expert proficiency in Python, Rust, or Go-based configuration management (Ansible/Terraform) for fleet-wide deployments.
• Strong understanding of SRE principles, including SLIs/SLOs, error budgets, and automation over manual "toil."
• Experience with enterprise MDM or Unified Endpoint Management (UEM) platforms (such as Jamf Pro, Microsoft Intune, FleetDM, Mosyle, Esper, 42Gears SureMDM, SOTI MobiControl, VMware Workspace ONE, or Headwind MDM).
• Experience with open-source device management solutions is a plus (such as FleetDM, Mender.io, Balena, Micromdm, Memfault, or RAUC).
• Experience with building Linux images and containers (with tools such as Yocto, PTXdist, ubuntu-image, Packer, Debian live-build, debootstrap).
• Experience with Linux packaging formats (such as deb, snap, flatpak, nixpkg).
• Hands-on experience troubleshooting hardware interfaces, specifically USB/Bluetooth barcode scanners and industrial touchscreen displays.
• Experience configuring and locking down browsers or native apps into dedicated kiosk environments on both Linux and mobile OSs.
• Hands-on experience with cloud infrastructure (AWS or Azure) and containerization technologies like Docker and Kubernetes.
• Experience with CI/CD pipelines tailored for edge device deployment.
• Experience with ROS (Robot Operating System) or managing hardware-in-the-loop systems is a plus.
• Background in warehouse automation, logistics, or industrial IoT.
