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.

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
