Job description

The Solutions Architect will play a critical role in designing and delivering secure, scalable, and resilient architectures across all initiatives within the Operational Telemetry (OT) program. This role ensures architectural consistency, security, and alignment with enterprise standards across the full portfolio of OT projects.

Key responsibilities include leading the architectural design for initiatives such as:

  1. Encryption of Control Data in Transit (ECDT) - ensuring secure data transmission across OT systems.
  2. Vulnerability Tracking and Remediation (VTR) - enabling proactive identification and mitigation of vulnerabilities.
  3. Human Machine Interface Hardening (HMIH)
  4. Zero Trust (ZT)
  5. Supply Chain Passport Process (SCPP)
  6. Engineer Laptop Hardening (ELH)
  7. Data of Last Resort (DLR)

The architect will define and deliver logical and physical architectures, data lineage, integration architecture, application usage, and both high-level and low-level designs. They will also establish support models and ensure alignment with enterprise architecture standards, regulatory requirements, and cybersecurity best practices.
