The TeamYou will be joining Valar Atomics' Automation and Controls Team within the Instrumentation, Control & Electrical (IC&E) organization. I&C Software Engineers own the logic and data layer PLC and DCS application code, ISA-88 batch sequences, SCADA and HMI applications, historian infrastructure, and enterprise integration across the reactor program and fuel manufacturing operations. You will work alongside I&C Hardware, electrical, process, and nuclear safety engineers in an environment that blends traditional control systems with modern software and data integration practice. As an early-career engineer, you will be surrounded by senior, staff, and principal engineers whose job includes developing you. The team values operator-focused design, data integrity, disciplined documentation, and a safety-first culture.
The RoleValar Atomics is seeking Automation and Controls Engineers to help develop, configure, test, and commission the control system software for our reactor and nuclear fuel manufacturing facilities. Working under the technical direction of senior and staff engineers, you will contribute across the controls software domain PLC programming, SCADA and HMI development, batch control, alarm configuration, historian work, and control system testing, with steadily increasing independence and ownership. This is an early-career position built for growth: you will write real application code that runs a real plant, spend time at panels and in the field during loop checks and commissioning, have your work reviewed and tested by experienced engineers, and learn nuclear-grade software discipline on a first-of-a-kind reactor program. We expect engineers at this level to develop toward independent ownership of controls software scope within their first few years.
Key Responsibilities - Develop and modify PLC and DCS application code on platforms such as Rockwell ControlLogix/CompactLogix, Siemens S7/TIA Portal, or equivalent, using IEC 61131-3 languages, working within established coding standards and template libraries and with structured code review by senior engineers.
- Build and maintain SCADA application content on platforms such as Ignition, FactoryTalk, AVEVA, or WinCC - tag databases, user-defined types, display instances, and scripting - from established templates and standards.
- Develop HMI displays at the panel and supervisory levels in accordance with the team's ISA-101/HPHMI style guide, including navigation, faceplates, and situational awareness graphics, with displays reviewed before release.
- Implement ISA-88 batch phase logic and equipment module code within the established batch architecture, under the direction of senior engineers; support recipe configuration and batch testing.
- Configure alarm setpoints, priorities, deadbands, and shelving in accordance with the approved alarm philosophy and rationalization outputs; run alarm performance KPI reports.
- Support safety logic work under IEC 61511 by executing functional test procedures, documenting test results, and assisting with safety application code under direct senior engineer supervision; safety logic authorship and approval remain with senior engineers.
- Configure historian tags, compression and exception settings, and asset framework elements within the established model; build process data dashboards and operational reports.
- Configure and troubleshoot industrial communication interfaces including OPC-UA, EtherNet/IP, and Modbus TCP/RTU under guidance - server and client endpoints, tag mapping, and SCADA-to-PLC connections.
- Write SQL queries and Python scripts for data processing, report generation, and control system test automation.
- Apply the team's software configuration management practice: version control, change control, structured code review participation, and controller and SCADA application backup and restore.
- Execute software FAT, SAT, and commissioning test procedures; support loop checks and end-to-end testing with I&C Hardware engineers; document results and maintain tag lists, alarm databases, and as-built software records.
- Troubleshoot control system software faults including communication failures, logic defects, sequence stalls, and historian data gaps, escalating appropriately and documenting findings and corrective actions.
- Support coordination with I&C Hardware Engineers on I/O assignment, tag naming, signal scaling, and loop commissioning.
- Maintain disciplined engineering records consistent with nuclear quality requirements, ensuring traceability of design decisions, software changes, and test results.
- Actively develop technical competence through structured learning, commissioning time, and progressively larger assignments, in line with the team's engineer development expectations.
Basic Qualifications- Bachelor's degree in Electrical, Electronic, Computer, Systems Engineering, Computer Science, or a related discipline.
- 2+ years of experience in controls software, PLC programming, SCADA development, or related automation work; substantial internship or co-op experience may be counted toward this at the hiring manager's discretion.
- Hands-on PLC programming experience with at least one major platform (Rockwell, Siemens, or equivalent) using one or more IEC 61131-3 languages.
- Some hands-on exposure to SCADA or HMI development on a major platform (Ignition, FactoryTalk, AVEVA, WinCC, or equivalent).
- Ability to read and interpret P&IDs, loop diagrams, and I/O lists sufficient to develop and test control logic.
- Basic familiarity with at least one industrial communication protocol (OPC-UA, EtherNet/IP, or Modbus).
- Working familiarity with version control concepts and disciplined change practice for application code.
- Willingness and ability to work hands-on during loop checks, commissioning, and plant support, including at times in industrial conditions and on commissioning schedules.
- Strong documentation habits and attention to detail, and willingness to work within a rigorous nuclear quality and checking culture.
- Ability to take direction, incorporate code review comments constructively, and communicate status and problems clearly.
Preferred Skills and Experience- Platform certification such as Ignition (Core/Gold) or Rockwell/Siemens training credentials.
- Engineer in Training (EIT) designation or passage of the FE exam.
- Internship, co-op, or work experience in process industries, manufacturing, utilities, or system integration.
- Exposure to batch control (ISA-88), alarm management (ISA-18.2), or HMI design (ISA-101) concepts.
- Exposure to plant historians (PI, Ignition Historian, or equivalent) or operational dashboarding.
- Exposure to safety system logic or functional safety testing concepts (IEC 61511).
- Experience with SQL, Python, or REST APIs for data processing or integration.
- Experience with Git or equivalent version control.
- Personal, academic, or professional projects demonstrating hands-on controls, automation, or software work.
