Systems Design Engineer

Sentrillion is seeking a Systems Design Engineer to support the design, deployment, installation, testing, verification, and administration of physical security systems, including surveillance, access control, intrusion detection, and other specialized systems. This role is ideal for an engineer who enjoys hands-on technical work, customer interaction, and being directly involved from concept through system acceptance. This is a chance to make a real difference while enjoying the flexibility of remote work.
What You'll Do
You will lead and support the design and development of physical security systems, including conducting site surveys, determining equipment placement, selecting appropriate technologies, and producing complete design and deployment documentation such as site survey reports, bills of materials, cost models, and system drawings using tools like Visio or AutoCAD.
You will work directly with customers to validate requirements, coordinate site access, provide technical status updates, and ensure designs meet customer, regulatory, and internal standards. Following established engineering and deployment processes, you will support system implementation by creating installation and subcontractor statements of work, providing detailed drawing markups, and assisting installation teams in the field.
This role involves hands-on participation in system installation and troubleshooting, recommending solutions to technical challenges during deployment, and ensuring conformance with statements of work, proposals, codes, and safety regulations. You will also conduct quality assurance activities, validation and verification testing, and develop test plans and documentation to support final system acceptance.
In addition, you will support system testing, integration, and evaluation activities; work with vendors on research, development, and installation support; and use diagnostic tools to calibrate, analyze, and validate system performance. You may lead small working groups, provide technical guidance, support bid and proposal efforts, and assist with ongoing system maintenance and administration activities.
Experience & Qualifications
A bachelor's degree in Engineering, Computer Science, Information Systems, or a related field is preferred, though equivalent experience (typically four years) may substitute for a degree. Candidates should have at least four years of broad technical experience, ideally supporting physical security, electronic, networked, or integrated systems in field or enterprise environments.
Strong experience with system design documentation, technical writing, site design, and tools such as Visio and AutoCAD is highly desired. Familiarity with network infrastructure, system configuration, test instruments, and field installation practices is preferred. Additional certifications related to security systems, networking, or enterprise technologies are a plus.
Successful candidates are detail‑oriented, self‑directed, and comfortable working both independently and within cross‑functional teams. You must be able to communicate complex technical concepts clearly to customers and internal stakeholders, manage multiple priorities in a fast‑paced environment, and adapt quickly to changing requirements.
Travel & Work Environment
This role requires frequent travel (up to 70%) to support site surveys and installation activities. You must be able to participate directly in installation and verification work, including working at heights, lifting equipment, using hand and power tools, and operating in outdoor environments with varying temperatures.
Security Requirements
U.S. citizenship is required due to government contract regulations. Candidates must be able to obtain and maintain the appropriate U.S. government security clearance and possess or obtain a valid U.S. passport.
