About the Role

The Principal AI Engineer sits at the intersection of software engineering, data science, platform architecture, and AI governance. You will be the technical owner of how AI/ML engineering is designed, built, governed, and shipped across a portfolio of products serving all of domains.

This is a hands-on engineering and technical leadership position. You will move fluidly between writing production code, architecting multi-tenant AI services, building internal developer tooling, leading security and governance design, and mentoring engineering teams. Your success is measured by team-level outcomes — scalable patterns that outlast your direct involvement.

 

What You'll Do

 

AI Productization & Platform Engineering

  • Design and own the firm's AI productization & governance playbook, covering service patterns, security/compliance standards, model evaluation rubrics, and production-readiness criteria.
  • Build and maintain reusable internal tooling, including AI service scaffolding, evaluation and monitoring tooling, and data infrastructure — designed for team adoption without ongoing hand-holding.
  • Establish AI agent governance policies covering agent permissions, code execution controls, access to internal systems, and human-in-the-loop enforcement.
  • Partner with Security, Legal, and Compliance to define SOC2/ISO-aligned AI controls, vendor DPA requirements, and prompt data classification policies.
  • Establish standardized deployment patterns using containerization, infrastructure-as-code, and CI/CD pipeline templates reusable across teams.

Developer Experience & Engineering Excellence

  • Champion AI-assisted development practices across the engineering org, including LLM-integrated development workflows, test-driven development patterns, and reusable tooling standards that scale across teams.
  • Codify modern software development standards (CI/CD, DevOps, testing, delivery quality) referenced by multiple teams as a baseline for new or re-platformed products.
  • Mentor engineers and tech leads with observable improvement in delivery consistency, design quality, and production readiness rigor.

Cross-Functional Leadership & Stakeholder Influence

  • Serve as the go-to technical authority on AI/ML, platform architecture, and engineering practices — regularly consulted by senior stakeholders at the design and strategy stages.
  • Bridge technical and non-technical stakeholders, translating complex architectural decisions, AI risk topics, and platform tradeoffs into clear, actionable guidance.

 

What You'll Need

Required

  • 15+ years in software engineering, data science, or a closely related technical field.
  • Bachelor's degree or higher in Computer Science, Engineering, or a related field.
  • Deep expertise in AI/ML frameworks and the Python ecosystem, with hands-on experience deploying models to public cloud infrastructure.
  • Demonstrated experience designing and operating multi-tenant AI services and LLM integrations in production.
  • Proven track record leading microservices architecture — decomposing monoliths, defining service contracts, and operationalizing CI/CD for distributed systems.
  • Strong hands-on command of containerization (Docker), infrastructure-as-code (Terraform), and modern DevOps practices.
  • Substantive experience with AI/LLM security — including prompt injection, data boundary enforcement, model supply chain risk, and AI-specific threat modeling.
  • Strong problem-solving skills, especially in building governance frameworks, evaluation rubrics, and reusable platform patterns at scale.
  • Excellent written and verbal communication skills in English; ability to translate complex technical topics to diverse audiences, including executive stakeholders.
  • Experience with Agile methodologies and cross-functional product team collaboration.

 

Preferred / Additional Qualifications

  • Experience applying AI/ML in business consulting, advisory, or professional services contexts.
  • Familiarity with AI service interface and gateway design patterns, including emerging AI integration protocols.
  • Contributions to open-source AI/ML projects, publications, or active involvement in technical communities.
  • Advanced certifications in AI, deep learning, cloud architecture, or security (e.g., AWS/GCP/Azure ML, CISSP).
  • Experience defining AI compliance controls for SOC2, ISO 27001, or TISAX frameworks.
  • Demonstrated enthusiasm for developer education — writing internal guides, running workshops, or building internal tooling communities.
  • Proficiency in additional languages is a plus (Go, Typescript) 
  • Demonstrated ability and enthusiasm to mentor and uplift junior team members or peers
  • Willingness to work outside of normal business hours, and in particular as unique projects/needs arise.
  • Ability to work full time in an office and remote environment; physically able to sit/stand at a computer and work in front of a computer screen for significant portions of the workday
  • Must become familiar with, and promote and abide by, our Core Values as defined by the and foster an inclusive environment with people at all levels of an organization
