Sr AI Architect​/Engineer

An extraordinarily talented group of individuals work together every day to drive TNS' success, from both professional and personal perspectives. Come join the excellence!

Researches, designs, plans, develops and/or evaluates new, advanced network technologies by translating customer requirements or strategic business objectives into final product design. Work typically includes in-depth assessment of the customer’s networked application needs, providing network modeling and simulation testing, consulting to further clarify needs, and engineering high-speed technology network transports to deliver application functionality.

TNS is moving from AI governance and foundations into execution. The platform building blocks are in place or underway
- Microsoft 365, Copilot, Entra , SharePoint, and Anthropic's Claude models via AWS Bedrock. What we don't yet have is a dedicated person who can both build and operate the secure, production-grade AI platform that lets AI work safely against our data and embed with our lines of business to turn that capability into measurable value.

This role does both. You'll be the technical engine and the on-the-ground partner who makes AI a productive, trusted tool across the enterprise - and who multiplies that impact by enabling others to build, not just building yourself.

Your time will span two connected halves.

Model platform and private hosting. Own our Claude deployment on AWS Bedrock end to end - model access and versioning, region and data-residency decisions, provisioned throughput vs. on-demand, and the private, VPC-isolated hosting posture that keeps our data inside our boundary and out of third-party training. Evaluate and manage additional models where they fit, and maintain a routing layer so applications aren't hard-wired to a single model or provider.

Harness and orchestration management. Build and maintain the application harness that sits between our users and the models: prompt and context management, tool and function calling, agent orchestration, retrieval pipelines, guardrails and content filtering, caching, and fallback behavior. Own the evaluation harness too - regression suites, quality benchmarks, and the release process that lets us upgrade models without breaking what's in production.

Data connectivity. Design and build secure, governed connections between AI systems and TNS data
- Microsoft 365 and Graph, SharePoint, databases, data warehouses, APIs, and line-of-business systems. Own the retrieval architecture, indexing and freshness strategy, and the permission-trimming that ensures every
