Senior AI Application Developer

HED is expanding how we bring artificial intelligence to life across our practice and into the broader industry. As an AI Application Developer, you design and build full-stack, AI-powered applications that translate complex data and machine intelligence into intuitive, human-centered tools. These applications begin as internal accelerators and evolve into scalable, client-facing solutions that support HED’s near-term commercialization strategy and long-term industry impact.

About HED

We are a team that is full of ideas, experience, creativity, passionate opinions, insatiable curiosity, uncompromising integrity, commitment, and skill. Our culture is about aspiration, embracing change and challenges, listening to (and learning from) each other, encouraging continual learning, and inspiring collective growth. As an inclusive, integrated architecture and engineering practice, we value the diversity of perspectives, experiences, abilities, and expertise that advance both the work we do, and the world we share.

Position Summary

Working within HED’s Data & AI Platform team, you operate with a high degree of ownership—shaping requirements, architecting solutions, and delivering production-ready systems. You collaborate across disciplines to integrate data engineering, knowledge systems, and AI models into cohesive applications that elevate decision-making and transparency.

You will focus on building AI-native, workflow-integrated systems that observe and augment real-world business processes—reducing manual data entry by inferring, capturing, and validating information from user activity across tools such as email, meetings, documents, and connected systems.

You work within a governance-first culture where architecture decisions are documented, reviewed, and held to evidence-based standards.

This role is suited for a builder who is energized by autonomy, driven by curiosity, and motivated to apply AI in real-world environments.

Essential Functions

• Own the full lifecycle of AI-powered applications, including requirements definition, architecture, development, deployment, and ongoing evolution
• Design and develop modern, performant web applications using React, with a focus on usability, accessibility, and clarity of experience
• Build and maintain backend services using Python (Flask required), ensuring scalable, well-structured API design
• Develop AI-native application features, including RAG-based workflows, conversational interfaces, and intelligent document generation
• Design and implement event-driven, agentic workflows that respond to real-world signals (e.g., emails, meetings, documents) and trigger appropriate system actions or user prompts
• Build systems that extract structured insights from unstructured data sources (natural language, documents, communications) to support downstream workflows and decision-making
• Integrate AI/LLM services (e.g., OpenAI, Anthropic) into production systems with attention to performance, cost, and reliability
• Collaborate with data developers and knowledge experts to translate pipelines and machine learning outputs into user-facing capabilities
• Partner directly with stakeholders across the firm to define problems, prototype solutions, and iteratively deliver meaningful outcomes
• Contribute to the development of shared platform capabilities, including component libraries, authentication patterns, and developer tooling
• Implement and maintain CI/CD pipelines, containerized deployments, and cloud infrastructure (Azure preferred)
