Assistant Instrumentation Control Engineer Jobs

Job Description Join a leading industrial engineering organisation at the heart of Houston's energy and manufacturing sector, where you'll take ownership of complex instrumentation and control projects from concept through to commissioning. This is a hands-on role with real influence over plant performance, system reliability, and safety, working alongside experienced engineers and operations teams on high-impact process facilities. About the Role: As an Instrumentation & Control Engineer, you will design, develop, and support process control systems that optimise plant performance and ensure safe, reliable operation.

You'll be responsible for translating process requirements into robust control strategies, specifying and integrating instrumentation, and supporting the full lifecycle of control projects. Your work will directly impact throughput, quality, and energy efficiency across multiple production units. Key Responsibilities: Develop and implement process control system architectures, including control strategies, logic diagrams, and functional specifications.

Design, configure, and optimise control loops for stability, responsiveness, and process performance across various unit operations. Specify, select, and document field instrumentation (flow, pressure, temperature, level, analytical) in line with process, safety, and environmental requirements. Interpret and develop P&IDs, ensuring accurate representation of instrumentation, control schemes, and interlocks for new and existing systems.

Configure and support industrial communication networks and protocols to integrate instrumentation, controllers, and higher-level control systems. Review and update control and instrumentation documentation using PDF editing tools to maintain accurate, current records and drawings. Provide technical support during installation, commissioning, troubleshooting, and plant modifications related to instrumentation and control systems.

Collaborate with process, mechanical, and electrical teams to ensure control system designs align with project objectives, standards, and regulatory requirements. Key Requirements: Proven experience in industrial instrumentation and control engineering within process industries (e.g., oil & gas, petrochemical, chemical, refining, or similar). Strong hands-on experience with process control system design, including control strategies, loop configuration, and control narratives

Demonstrated capability in control loop tuning and optimisation for both regulatory and advanced control applications. Solid background in instrumentation specification and selection for hazardous and non-hazardous areas. Proficiency in reading, interpreting, and developing P&IDs and related engineering drawings.

Working knowledge of industrial networking and communication protocols (e.g., Modbus, Profibus, Ethernet/IP, Foundation Fieldbus, or similar). Competence in using PDF editing tools for mark-ups, redlines, and document control. Strong analytical, problem-solving, and troubleshooting skills with the ability to support live plant operations

Desirable Skills: Experience with DCS, PLC, and SCADA platforms used in large-scale process facilities. Familiarity with safety instrumented systems (SIS) and related standards (e.g., IEC 61511). Exposure to advanced process control (APC) or optimisation projects

Experience working within multi-discipline project teams on brownfield and greenfield projects. Knowledge of relevant industry codes and standards for instrumentation and control. Qualifications: Bachelor's degree in Instrumentation & Control Engineering, Electrical Engineering, Chemical Engineering, or a closely related discipline.

Professional Engineer (PE) license in Texas or eligibility/in-progress status preferred. Additional certifications or formal training in process control, industrial networking, or functional safety are advantageous. If you're a driven Instrumentation & Control Engineer looking to take ownership of impactful projects in a dynamic industrial environment, we'd like to hear from you.
