Senior Principal Solutions Architect (Remote)

As a go-to architect and strategist within 8th Light, you'll partner with one or two clients a year on their hardest architecture challenges, while deepening your and our collective expertise over the course of your career with us.

This role sits at the intersection of long-term planning and hands-on technical leadership. You'll work across the enterprise to map data dependencies, drive legacy modernization, and define how domains like pricing fit into a broader enterprise data and AI ecosystem. One day that might mean aligning teams to deliver new low-latency data sets; the next, running architecture trade-off analysis with senior product, design, and business leadership.

A significant part of the work involves mapping application dependencies and capabilities, building an enterprise-wide context graph, and contributing to an MCP server built on enterprise architecture tooling, all aimed at giving teams (and the AI-assisted tools they use) the context to make better design, trade-off, and risk decisions.

Day-to-day output is hands-on architecture and design: planning artifacts, architecture diagrams, decision records, and roadmap contributions. This isn't a feature-delivery role, but you'll need enough data and technical depth to make well-informed calls, design real systems, and build credibility with technical stakeholders.

Do you have experience in Risk assessment?, You've spent over 10 years architecting large, distributed systems across complex, multi-stakeholder environments. You move comfortably between long-term planning and hands-on design, building trust with executives focused on business value and the engineers who own implementation.

You'll be well-suited if you have:

• Deep experience in enterprise architecture at scale, across large, distributed systems
• Strong data fluency, dependency mapping, data mesh enablement, high-availability and low-latency design
• Hands-on experience with the stack: Kubernetes, Kafka, Cassandra, Java, TypeScript, AWS, protobuf, Databricks, GraphQL, and REST
• Comfort using AI-assisted development and agentic coding tools to accelerate delivery and enable non-technical teams
• A track record of working across teams on complex, multi-stakeholder technical decisions, including trade-off and risk analysis (e.g. SPADE, architecture decision records)
• Credibility and trust building across a group including executives who will be focused on business value and senior technical stakeholders who will be focused on implementation
• Strong domain-driven design instincts and comfort with the ambiguity of both greenfield and legacy work
