Description

The company is hiring an AI Lead Engineer, Technical Lead to help build the engineering base of its Services AI Platform, a multi-tenant, production-grade system that runs agentic AI at enterprise scale.

This is a player-coach role: you write code yourself and also set technical direction, with ownership of a platform meant to be dependable, resilient and able to scale.

You will convert complicated enterprise workflows into automated, intelligent systems with measurable results across the company's global operations.

Responsibilities

  • Build full-stack components for the AI platform in Python and Angular, including interfaces for fine-tuning large language models and dashboards for tracking experiments.
  • Design and tune multi-tenant agents with modular orchestration approaches such as ReAct and ReWOO so production agent workflows scale.
  • Create Model Context Protocol servers that keep agents decoupled, so they communicate only through defined API boundaries.
  • Build advanced retrieval-augmented generation pipelines, including Knowledge Graph RAG, LightRAG and RAPTOR hierarchical summaries, for sophisticated enterprise data retrieval.
  • Connect vector and graph databases such as Neo4j and pgvector to support complex, thematic retrieval at platform scale.
  • Write precise prompt and intent classification logic that prevents workflow collisions and makes sure agents read instructions correctly.
  • Work with subject matter experts to turn their domain knowledge into agent-driven automation.
  • Work with UI and API teams to deliver complete, end-to-end integrations across the platform.

Requirements

  • At least 10 years of software engineering experience, including at least 5 years building AI and machine learning solutions that ran in production.
  • At least 2 years of hands-on generative AI work, covering large language model development, retrieval-augmented generation and prompt engineering.
  • At least 3 years leading technical teams and owning end-to-end delivery of complex software or AI platforms.
  • Deep practical experience with AWS infrastructure and services for AI and machine learning workloads.
  • A portfolio of AI solutions deployed into live business environments that shows both technical depth and delivery ownership.
  • A Bachelor's or Master's degree in Computer Science, Data Science, AI or a related field.

Conditions

Hybrid role: 3 days a week in the office and 2 days remote.

Full-time position.

Base salary range: $120,800.00 to $170,800.00.

The company uses automated processing and AI to match skills to roles, but every hiring decision is checked and made by people, not by automated decision-making.

This job opening fills an existing vacancy.

Equal opportunity employer; see the company's EEO policy statement and the Know Your Rights poster.

Benefits

  • Work on the forefront of enterprise AI engineering within a global platform team, where your code ships to production and your architecture decisions shape the platform.
  • Access to advanced AI infrastructure, tools and frameworks.
  • Technical training, industry conferences and structured career growth pathways.
  • Lead engineering work at global scale, influencing how the company builds and deploys intelligent automation across the enterprise.
  • Competitive compensation and a comprehensive financial wellbeing package for a Vice President-level role.
  • Wellbeing programs to help you stay balanced and perform well over the long term.
