1d•$100,000 - $150,000•Onsite

About The Position

We are seeking an experienced software engineer to lead the design, integration, and development of our Access Control, Intrusion Detection, and Video Surveillance Systems in industrial, nuclear power plant environments. Project Management background is helpful. This role involves hands-on technical leadership across system architecture, integration, and development oversight of nuclear plant physical protection systems. The engineer will be responsible for the design and integration of physical security systems, both software and hardware, which are on-prem, completely closed systems with no Internet, wireless, or cloud computing, and involve a redundant network design for no single point of failure. The systems must meet regulatory compliance (10 CFR 73), high-reliability, and long-term operability specific to the nuclear power plant industry. The role requires integrating hardware, software, communications, sensors, actuators, and HMIs into cohesive system solutions, and providing technical direction to vendors, integrators, and internal development teams. The engineer will also author, maintain, and control system documentation, support system development activities, participate in FAT, SAT, installation oversight, and system commissioning, and resolve technical issues. Occasional travel to customer sites for walkdowns, meetings, and brief installation oversight is required.

Requirements

Bachelor’s degree in Engineering (Electrical, Software, Systems or related).
5+ years of experience designing and integrating systems.
Experience writing software in multiple languages (C, C++, GO, shell scripting).
Working knowledge of Linux (Ubuntu, Red Hat, DEBIAN) and Windows
Strong knowledge of networking (IPV4, VLAN, TCP/IP, subnets, SFPs, network switches)
