Core Mission

The Senior Enterprise Applied Agent Builder owns the end-to-end delivery of complex AI services and Generative AI features that automate or augment critical enterprise workflows. The role combines strong software engineering execution with multi-step agent design, human-centered product thinking, and production operations discipline.

This individual leads solution design from discovery to deployment, integrates AI capabilities into enterprise platforms, and establishes measurable quality and adoption outcomes. They also mentor junior engineers and contribute reusable patterns that help the organization ship agentic solutions more consistently.

Key Responsibilities

This is a hybrid role blending hands-on delivery with technical ownership, evaluation rigor, and cross-functional leadership.

1. End-to-End Ownership of Complex AI Services (55% of time)
Own the development of a complex AI service or GenAI feature, delivering from concept through production rollout and ongoing iteration.
Translate ambiguous business requirements into concrete user stories, acceptance criteria, and technical implementation plans.
Integrate agentic solutions with enterprise systems (e.g., CRMs, ERPs, HR platforms, data warehouses, internal APIs) and ensure production-grade performance through rapid iteration and troubleshooting.
Lead pilot launches and transitions, including documentation, user enablement, and stakeholder alignment.

2. Multi-Step Agent Architecture, Evaluation & Operations (30% of time)
Lead the design and implementation of multi-step agents, including tool/function calling, retrieval, state management, and human-in-the-loop oversight where required.
Develop evaluation approaches (test suites, golden datasets, regression checks) and optimize solutions for accuracy, latency, reliability, and cost.
Implement production observability (logging, tracing, monitoring) and contribute to runbooks and incident response processes for AI services.

3. Reusable Patterns, Standards & Mentorship (15% of time)
Extract successful patterns from delivery work to create reusable libraries, templates, and reference implementations for other teams.
Lead technical reviews and share best practices for secure, reliable, and user-trustworthy agentic systems.
Mentor and coach P1-P2 engineers through code reviews, design reviews, and day-to-day execution.

Required Qualifications

8+ years of experience in software engineering, including ownership of production services.
3+ years building and deploying AI/ML or Generative AI solutions that deliver measurable business results in production.
Strong proficiency with LLM application patterns: prompt engineering, Retrieval-Augmented Generation (RAG), and tool/function calling within agentic systems.
Experience with agent frameworks (e.g., LangChain, LlamaIndex, Semantic Kernel, Microsoft Agent Framework, or similar).
Hands-on experience with enterprise integrations, authentication/authorization, and secure API design.
Operational excellence: familiarity with logging, tracing, monitoring, performance tuning, and cost management for AI applications.
Strong communication skills and demonstrated ability to lead cross-functional delivery with business and technical stakeholders.
Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
