The opportunity
This is a unique opportunity for a Senior Instrumentation & Controls Engineer to join the business at an early stage of its US growth and play a key role in shaping local and global project delivery.

You will take a leading role in the delivery of I&C solutions, providing technical direction and contributing to key design decisions. You will collaborate closely with experienced engineers across Mipac’s global offices and support the development of less experienced engineers within the team.
This role offers exposure to large-scale projects delivered internationally and includes opportunities to work directly with clients. Depending on project needs, the role may over time include travel to site locations in North America and internationally.

As part of a multidisciplinary project delivery team, you will:
Lead the design and implementation of instrumentation and control systems across complex projects.
Take ownership of key I&C deliverables and ensure quality, consistency, and alignment with project requirements.
Develop and review P&IDs, control philosophies, and functional descriptions.
Oversee the preparation of I&C deliverables, including:
I/O lists and signal schedules
Instrument datasheets and specifications
Loop diagrams and wiring details
Functional descriptions and control narratives
Alarm registers and cause & effect matrices
FAT, SAT, and commissioning documentation
Provide technical leadership in PLC and SCADA system design, configuration, and testing.
Lead or play a key role in FAT, SAT, and commissioning activities, including troubleshooting complex system issues.
Mentor and support junior engineers, providing guidance and technical review.
Work closely with process, electrical, and mechanical disciplines to drive integrated solutions.
Engage directly with clients and contribute to technical discussions and decision‑making.
What we are looking for
Extensive experience working in a project‑based engineering environment, such as an EPC, system integrator, or owner‑operator.
Strong hands‑on experience with PLC programming and industrial control systems.
Experience leading I&C design and delivery across complex projects.
Proven ability to take ownership of deliverables and provide technical direction within project teams.
Experience mentoring or guiding less experienced engineers.
Strong understanding of instrumentation fundamentals and control systems.
Experience with SCADA/HMI development (e.g., FactoryTalk, DeltaV Live, or similar).
Demonstrated experience in commissioning and troubleshooting in live environments.
Strong communication skills, with the ability to engage with clients and lead technical discussions.
Preferred (but not required):
Experience in mining, mineral processing, heavy industry, or similar process‑based environments.
Familiarity with multiple PLC/DCS platforms (e.g. Rockwell, DeltaV and/or Siemens).
