About the Role

Design and deliver cutting-edge AI solutions that solve complex, real-world business challenges and shape the future of work. This hands-on role involves partnering with stakeholders to translate needs into scalable, AI-powered solutions, owning the full lifecycle from architecture to adoption, and embedding AI into real workflows.

Responsibilities

  • Design and build AI-enabled applications, copilots, agents, extraction pipelines, prediction interfaces, and decision-support tools using foundation models, retrieval-augmented generation, structured outputs, and orchestration frameworks.
  • Work directly with business teams, product owners, clients, or operational users to understand real workflows, constraints, data quality issues, and adoption barriers, then translate these into working technical solutions.
  • Build and tune LLM workflows, prompt strategies, schema-driven extraction, tool-calling patterns, agent orchestration, evaluation loops, and human-in-the-loop controls.
  • Integrate AI solutions with enterprise systems, APIs, data platforms, document repositories, workflow tools, observability platforms, and identity and access management services.
  • Ensure AI solutions meet enterprise standards for reliability, scalability, latency, maintainability, cost control, logging, monitoring, and operational support.
  • Create evaluation datasets, test harnesses, validation tools, regression checks, and quality review workflows to measure accuracy, extraction quality, hallucination risk, and business usefulness.
  • Define solution architecture, engineering standards, reusable patterns, and implementation approaches for AI-enabled platforms and services.
  • Work with engineering, data, and business teams to prepare structured and unstructured data, improve metadata, design retrieval strategies, and identify gaps in source content.
  • Embed access controls, audit logging, data protection, responsible AI controls, security review, and compliance requirements into the AI delivery lifecycle.
  • Support users through demos, pilots, training, feedback loops, documentation, and iterative improvement so that deployed AI solutions create measurable business value.

Requirements

  • Strong enterprise engineering background.
  • Deep expertise across modern full-stack technologies (.NET, Azure, SQL, React/Angular).
  • Experience in distributed systems.
  • Experience in observability.
  • Experience in AI tooling such as LLMs, retrieval pipelines, and agentic workflows.
  • Ability to mentor others.
  • Ability to resolve production challenges.
  • Ability to scale prototypes into robust, enterprise-grade solutions.
