Senior Solution Architect

Responsibilities

• Design end-to-end architectures for AI-native solutions: orchestration, retrieval, tool and system integration, agent autonomy and guardrails, identity and authorization, evaluation, observability, and cost model
• Fit each solution exactly to the business scope - no more, no less - and be able to explain what you deliberately left out and why
• Turn incoherent or contradictory requirements into explicit business decisions: surface them, reframe them in business terms, price the options, and get a named owner to decide
• Make and document architectural trade-offs (build vs buy, model selection, retrieval strategy, autonomy level, cost vs quality) in a form that stakeholders can challenge and future teams can trust
• Define the evaluation strategy for each system: how we will know that an assistant or agent fits the business scope, not just that it produces fluent output
• Author the constraints, guidelines, and architectural fitness functions that engineering teams and coding agents build within, and revise them as the organization learns what generation gets wrong
• Decide where humans must stay in the loop - regulated decisions, data of record, security boundaries, anything with legal or contractual consequence
• Work within EPAM delivery teams and in presales: shape proposals, present options and costs to client executives, and review designs across teams
• Build proofs of concept and reference implementations when, and only when, a decision needs evidence or a team needs an example of "good"
• Contribute to EPAM's AI architecture practice: reference architectures, reusable patterns, and mentoring architects who are transitioning into AI-native design
