10 Solutions Architect Roles in IIoT and OT Worth a Look Right Now
Ten solutions architect openings on IIoTjob that stand out, from industrial data platforms and MES to OT cybersecurity and edge computing. Presented in no particular order, with what each role involves and who it suits.
The solutions architect is one of the most interesting jobs in industrial tech right now. It sits right where plant-floor reality meets enterprise IT, cloud and AI, and it rewards people who can talk to an operator, an IT security lead and a CFO in the same week.
We went through the open roles on IIoTjob and picked ten that stand out: for the problems they solve, the technology involved, or the kind of career they open up. They are listed in no particular order. Which one is "best" depends entirely on where you are and where you want to go, so we describe each one and leave the ranking to you.

What these roles have in common
Read the ten postings side by side and a clear profile emerges:
- OT protocols are table stakes. OPC UA shows up again and again, with MQTT close behind.
- Data architecture matters as much as connectivity. Historians, contextualization, asset models and Unified Namespace are in many of the listings.
- Security is part of the design. IEC 62443 and network segmentation appear even in roles that aren't labeled "security."
- Customer-facing skills count. Workshops, discovery and pre-sales support are part of most of these jobs, not just the technical design.
