Solutions Architect (Operational Technology)

Lumen Solutions Group Inc • Washington, DC

4h • Remote

About The Position

Lumen Solutions Group Inc. is seeking a Solutions Architect with a focus on Operational Technology. This role requires a deep understanding of both IT and OT systems, with a strong emphasis on designing and implementing solutions for the transportation industry. The ideal candidate will have extensive experience in architecture, integration, and cloud platforms, with the ability to translate operational needs into technical designs. This is a remote contract position with quarterly travel required for PI Planning.

Requirements

• 10+ years of progressive IT/technology experience with a foundation in hands-on engineering delivery (application development, systems integration, or data platform work).
• 5+ years as a Solutions or Enterprise Architect with demonstrated ownership of complex, multi-system solutioning in rail, transit, airlines, or transportation operations.
• Proven ability to perform structured business process analysis (process mapping, As-Is/To-Be modeling, gap analysis, workflow decomposition).
• Deep command of integration architecture: event-driven patterns, REST/GraphQL APIs, pub/sub and streaming (Kafka or equivalent), and data exchange across OT/IT boundaries.
• Experience designing for 24/7 operational availability on cloud and hybrid platforms (AWS, Azure, or GCP).
• Familiarity with the reliability, latency, and fault-tolerance requirements of safety-adjacent rail environments.
• Demonstrated ability to produce rigorous, execution-grade architecture artifacts.
• Direct engagement experience with operational stakeholders.
• Prior contractor or consulting engagement model experience.

Nice To Haves

• Exposure to scheduling, dispatch, crew management, asset maintenance, and train control as a connected operational ecosystem.
• Familiarity with AI/ML-enabled operations (predictive maintenance, anomaly detection, scheduling optimization, computer vision inspection pipelines).
• Experience with lakehouse architecture (Databricks, Delta Lake, Unity Catalog) applied to operational and engineering data.

Responsibilities

• Lead technical solutioning for operational data pipelines, including real-time streaming ingestion, event processing, and lakehouse patterns for train performance, delay causality, and asset health data.
• Perform structured business process analysis, including process mapping, As-Is/To-Be modeling, gap analysis, and workflow decomposition.
• Design and implement integration architecture, utilizing event-driven patterns, REST/GraphQL APIs, pub/sub, and streaming technologies.
• Design solutions for 24/7 operational availability on cloud and hybrid platforms (AWS, Azure, or GCP), considering the reliability and fault-tolerance requirements of safety-adjacent rail environments.
• Produce rigorous, execution-grade architecture artifacts such as solution design documents, integration maps, API contracts, non-functional requirement matrices, and Architecture Decision Records.
• Engage directly with operational stakeholders, including dispatchers, controllers, planners, and front-line supervisors, to ensure architecture decisions are grounded in actual workflow context.
• Provide technical inputs for RFPs/RFQs, conduct vendor evaluations, and participate in architecture governance.
• Deliver independently, manage scope, communicate proactively on blockers, and maintain artifact quality without close supervision.
