Senior Software Engineer II

About The Role:

This position performs complex research, design, and software development assignments in the design and delivery of production AI systems, including agentic workflows, LLM-powered pipelines, retrieval-augmented generation (RAG), and structured extraction services. The position provides direct input to project plans, schedules, and methodology for cross-functional AI products; performs system design, typically across multiple systems and data sources; mentors more-junior members of the team; and works directly with business users and stakeholders to translate ambiguous, unstructured problems into measurable AI solutions.

Requirements:

• 5+ years of software engineering experience, including 2+ years building and shipping LLM-based or ML-based systems to production

• BS in Engineering/Computer Science or equivalent experience required

• Demonstrated track record of owning an AI feature or service end to end: design, evaluation, deployment, and monitoring
• Expert proficiency in TypeScript/Node.js and/or Python; working knowledge of C#/.NET is a plus

• Hands-on experience with LLM platforms and APIs (Azure OpenAI or equivalent), including prompt design, tool/function calling, structured outputs, and model selection tradeoffs
• Experience building RAG pipelines: chunking, embedding, hybrid retrieval, reranking, and grounding/citation

• Strong understanding of schema-driven structured extraction from unstructured data (Zod, Pydantic, JSON Schema) and validation strategies

• Experience with evaluation frameworks for AI systems: golden datasets, LLM-as-judge, precision/recall on extraction tasks, regression testing of prompts and agents

• Strong SQL proficiency and understanding of relational and vector data storage (SQL Server, PostgreSQL, Elasticsearch/vector stores)

• Working experience with both AWS and Azure, including compute, storage, networking, IAM, and managed AI services; containerized deployment (Docker, Kubernetes or equivalent), secrets management, and observability (token usage, latency, cost attribution)
• Strong knowledge of software development best practices, test-driven development, and code review

Responsibilities:

• Design, build, and deploy production AI systems including agentic workflows, RAG services, and extraction pipelines across multiple business units

• Interface with business stakeholders and technical team members to scope AI use cases, define success metrics, and finalize requirements

• Write and review detailed technical specifications and architecture documents for complex AI system components

• Build and maintain evaluation harnesses; establish accuracy, latency, and cost baselines and monitor them in production

• Implement responsible AI practices: data handling, PII controls, hallucination mitigation, auditability, and human review where required

• Own cost and performance of LLM workloads, including model selection, caching, and usage attribution
• Build and maintain CI/CD pipelines and deployment automation for AI services across AWS and Azure environments

• Operate in Agile development environments while collaborating with key stakeholders across engineering, product, and business functions

• Mentor less-senior engineers on AI system design, evaluation methodology, and production readiness
