Job Description
Where critical infrastructure meets real-world digital engineering.
This role sits at the intersection of Operational Technology and enterprise digital systems. As our OT Application Architect, you will be designing the application layer that supports a 24/7, safety‑critical environment. This is not generic IT environment – you will be architecting decision systems that sit above assets that cannot afford downtime.
Your mission is to drive IT/OT convergence in a regulated industry. You will bridge the gap by designing secure, high‑availability solutions that pull real-time data from OT systems and expose it safely to enterprise platforms. You will work as the translator between Control Systems Engineers and Cloud/Digital teams, ensuring data moves reliably, securely and with operational intent.
At NCS, you will work inside a high-performance specialist squad – Cyber, Infrastructure, Data, Quality and OT engineers working as one team. With strong partnerships across SAAS providers and hyperscalers, you will have access to modern Industrial IoT ecosystems and the tools needed to modernise a complex environment.
Qualifications
You understand that software in a critical operational environment is operationally consequential. You are pragmatic, comfortable around physical systems, and capable of modernising legacy OT applications without disrupting existing critical operations.
You will bring:
- Industrial Expertise – Extensive experience in software architecture across OT‑heavy environments such as resources, energy and/or logistics
- Purdue Model Exposure – Understanding of ISA‑95 and how to safely bridge OT Level 3 and IT Level 4 networks.
- Critical Systems Integration – Experience on integrating between OT Systems and core IT systems.
- Protocol Skills – Strong capability across OPC UA, MQTT, BACnet, Modbus or similar industrial protocols.
- Edge & IoT – Strong knowledge of IoT and designing edge‑processing pipelines that sync securely to the cloud.
- Cyber Awareness – Understanding of critical infrastructure security obligations when exposing operational systems to cloud environments.
- Modernisation Skills – Ability to uplift legacy OT applications into modern patterns while maintaining operational continuity.
