What is a safety instrumented system engineer?

Safety Instrumented System (SIS) Engineers are specialized professionals responsible for designing, implementing, and maintaining automated safety systems in industrial environments, such as oil and gas, chemical, and manufacturing plants. Their primary role is to ensure that safety systems, like emergency shutdowns and alarms, function correctly to protect people, equipment, and the environment from hazardous incidents. SIS Engineers work closely with other engineering disciplines to assess risks, develop safety requirements, and verify that safety systems comply with industry standards. They are essential for maintaining regulatory compliance and minimizing operational risks.

What are the key skills and qualifications needed to thrive as a safety instrumented system engineer?

To thrive as a Safety Instrumented System Engineer, you need a solid background in control systems engineering, process safety, and safety standards like IEC 61511, usually supported by a degree in engineering and relevant work experience. Familiarity with safety PLCs, Distributed Control Systems (DCS), safety lifecycle management tools, and certifications such as TÜV Functional Safety Engineer are typically required. Strong analytical thinking, attention to detail, and effective communication are crucial soft skills for collaborating with multidisciplinary teams and ensuring system integrity. These competencies are essential to design, implement, and maintain safety systems that protect people, assets, and the environment in high-risk industrial settings.

What are some common challenges faced by safety instrumented system engineers on large industrial projects?

Safety Instrumented System Engineers often encounter challenges such as ensuring compliance with international safety standards (like IEC 61511), integrating safety systems with existing plant control systems, and managing complex documentation requirements. Collaboration with multidisciplinary teams—such as process engineers, control engineers, and project managers—is essential to align safety requirements with operational needs. Additionally, these engineers must frequently troubleshoot unexpected issues during commissioning and ensure that all safety functions are properly validated before start-up.

What is the difference between Safety Instrumented System Engineer vs Control Systems Engineer?

AspectSafety Instrumented System EngineerControl Systems Engineer
CertificationsFunctional Safety certifications (e.g., IEC 61511, IEC 61508)Control system design and programming certifications (e.g., PLC, DCS)
Work EnvironmentIndustrial plants, process industries, safety-critical systemsManufacturing, automation, process control environments
Industry UsageProcess safety, oil & gas, chemical manufacturingAutomation, manufacturing, building management
Primary FocusEnsuring safety integrity and risk reductionOptimizing control processes and system performance

The Safety Instrumented System Engineer focuses on designing and maintaining safety systems to prevent accidents, emphasizing safety integrity and risk management. In contrast, the Control Systems Engineer concentrates on controlling and automating processes for efficiency. While both roles work within industrial environments and may require technical certifications, their core responsibilities differ significantly in safety versus control optimization.

Job description

About Valar Atomics
At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable, unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.
The Team
You will be joining Valar Atomics' IC&E Engineering team within the Fuel Manufacturing group. I&C Hardware Engineers own the physical measurement and control layer, field instrumentation and final elements, control panels and I/O architecture, field wiring and network infrastructure, and safety instrumented system hardware. You will work alongside I&C Software, process, electrical, mechanical, and nuclear safety engineers in a hands-on environment where measurement quality and installation integrity directly support production reliability and nuclear safety. The team values technical depth, disciplined documentation, and a safety-first culture.
The Role
Valar Atomics is seeking a Staff I&C Hardware Engineer to specify, design, install, commission, and maintain the instrumentation and control hardware for nuclear fuel manufacturing facilities. The role covers field instrument and final element selection, control panel and I/O architecture design, hazardous area classification, safety instrumented system hardware, field wiring and network infrastructure, calibration, loop commissioning, and control loop tuning with senior responsibility for technical leadership of complex projects, contractor oversight, and mentorship of junior engineers.
Key Responsibilities
  • Select, size, and specify field instrumentation including flow, pressure, differential pressure, temperature, level, and analytical devices; produce instrument data sheets, specifications, and requisitions.
  • Size and specify final control elements including control valves, actuators, positioners, regulators, on-off valves, and flow elements; perform valve sizing, noise and cavitation checks, and actuator thrust verification.
  • Design control panels and remote I/O architecture including enclosure layout and rating, I/O module and channel allocation, terminal and marshalling arrangement, power distribution, UPS sizing, isolators, and intrinsic safety barriers.
  • Perform hazardous area classification and select equipment for classified areas in accordance with NEC Article 500/505 or IEC 60079; prepare intrinsic safety loop calculations and verify entity parameters.
  • Own instrumentation engineering documentation for capital projects including the instrument index, loop diagrams, hook-up drawings, I/O lists, instrument location plans, cable schedules, and P&ID instrumentation mark-ups; establish drawing and tagging standards and review deliverables prepared by junior engineers and contractors.
  • Own safety instrumented system hardware scope including SIL determination, safety sensor and final element selection, redundancy and voting architecture, proof test interval and procedure development, and SIL verification calculations in accordance with IEC 61511 and IEC 61508; review SIS hardware deliverables prepared by junior engineers and contractors.
  • Tune PID and advanced regulatory control loops; commission field instrumentation; diagnose and resolve loop deviations, valve response problems, and measurement quality issues.
  • Establish and execute the instrument calibration program including calibration procedures, ranges, tolerances, traceability to NIST-referenced standards, calibration records, and recall scheduling.
  • Specify and oversee installation of field wiring and physical OT network infrastructure including cable schedules, tray and conduit routing, media selection, signal and power segregation, grounding and shielding practice, and field switch and cabinet placement.
  • Prepare and execute hardware FAT, SAT, and commissioning plans; perform point-to-point continuity checks, loop checks, calibration verification, and end-to-end interlock testing from sensor through final element; produce turnover and as-built documentation.
