Primary responsibilities include site commissioning, hardware and software testing, system troubleshooting, and post-deployment support such as preventative maintenance. Beyond field execution, the CSE contributes to control system development as a hands-on technical resource. The role provides a structured pathway toward senior engineering positions. CSE Key Responsibilities * Assist the Senior Controls Engineer in the design and development of PLC, SCADA, and HMI solutions. * Support system configuration including virtual machines, SCADA servers, and control networks. * Conduct Functional Acceptance Testing (FAT) and Site Acceptance Testing (SAT) with internal teams and clients. * Perform site commissioning - instrumentation checkout, loop testing, and startup support. * Provide troubleshooting, maintenance, and technical support for deployed systems; perform updates, backups, and change management post-deployment. * Configure and install virtual servers, clients, and network equipment per project specifications. * Configure and troubleshoot Variable Frequency Drives (VFDs) using electrical ladder schematics. * Interpret and apply electrical schematics, P&IDs, and control loop drawings in the field; document revisions and improvements. * Ensure site safety compliance and adherence to startup protocols during field activities. What Sets This Role Apart: The CSE sits between the hands-on field implementation work and the design-leading Senior Controls Engineer. You'll do real design and development work under the SCE while owning field execution end-to-end - making it the natural growth step toward senior engineering., The Senior Controls Engineer leads the design, development, and implementation of advanced industrial automation SCADA systems and serves as the technical authority across all project phases - requirements analysis, control system architecture, engineering documentation, and site commissioning. The SCE mentors junior engineers, leads engineering deliverables, ensures technical compliance, and engages directly with clients and stakeholders. This role drives innovation, maintains quality standards, and supports the full deployment and lifecycle of automated control systems. SCE Key Responsibilities * Lead the design and development of PLC, SCADA, and HMI systems across Rockwell, Siemens, and Schneider platforms. * Develop and review technical documentation: Process Control Narratives (PCNs), System Commissioning Plans (SCPs), I/O lists, network architectures, and control panel layouts. * Oversee and execute control system software development - advanced logic, interlocks, alarms, and sequencing. * Oversee and conduct testing phases: Internal Quality Control (IQC), Factory Acceptance Testing (FAT), and Site Acceptance Testing (SAT). * Lead on-site startup, commissioning, and troubleshooting for new installations and upgrades. * Interface with clients, project managers, and cross-disciplinary teams to align deliverables with scope, budget, and timeline. * Supervise and mentor Control Systems Engineers and Application Engineers, providing technical guidance and performance feedback. * Ensure designs meet industry standards, client specifications, and safety regulations; support change control and lifecycle maintenance. * Drive continuous improvement in engineering workflows, templates, and design practices; coordinate weekly with project stakeholders. What Sets This Role Apart: The SCE is the engineering department's technical authority and the most senior design role in this posting. It is design-and-leadership focused rather than field-execution focused, and it carries direct mentorship responsibility for CSEs and Application Engineers., * Municipal Water & Wastewater - treatment, distribution, telemetry, pump control, and EPA-compliant regulatory reporting. * Food & Beverage - sanitary design, CIP/SIP, batch processing, traceability, and MES/ERP integration (FDA/USDA/FSMA). * Energy & Defense - power distribution, environmental, and secure control systems. Why Join ATSI * Clear growth paths. Every role in this posting is leveled, with structured cross-training toward senior engineering leadership. * Real, mission-critical work. You'll commission and support systems that keep water flowing, food safe, and infrastructure secure. * Work across the full lifecycle. From design through commissioning, support, and upgrades - not just one slice of the project. * A collaborative, safety-first culture grounded in our core values. ## Related Videos - [Optimizing Land-Based Fish Feeding with Node-RED](https://www.wearedevelopers.com/videos/2032-optimizing-land-based-fish-feeding-with-node-red) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Enabling intelligent logistics automation: home-grown Industrial IoT platform at Austrian Post](https://www.wearedevelopers.com/videos/2018-enabling-intelligent-logistics-automation-home-grown-industrial-iot-platform-at-austrian-post) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) ## Related Articles - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
