Is this role right for you?
Strategy & Responsible AI Governance – Work with the business to define and implement a strategy for trustworthy, personalized natural language and agentic interfaces — embedding fairness, transparency, and accountability from design through deployment
Act as lead engineering partner to translate business requirements into responsible architectural patterns and best practices for agentic AI development, balancing innovation with risk and ethical guardrails
Partner with Data, security, risk, legal, and engineering teams to embed AI‑driven resiliency, observability, bias detection, and threat modeling into architecture and governance standards
Champion model risk management practices (e.G., SR 11‑7), regulatory alignment, and readiness for emerging AI regulation across the agentic AI portfolio
Architecting a Responsible Agentic Development Platform and Practice
Work as part of a team defining and delivering the strategy, technical components, and guardrail patterns for a responsible agentic AI ecosystem
Design and implement secure, resilient, and compliant AI platforms that integrate with existing enterprise systems, ensuring alignment with risk, ethics, fairness, and regulatory frameworks
Build on knowledge of event‑driven architecture, message queues, and distributed systems to build resilient, auditable, and scalable agentic workflows in a secure and compliant manner. – Drive search and retrieval architecture, including vector‑based search systems, indexing strategies, and relevance optimization, with attention to provenance, grounding, and hallucination mitigation
Design and embed responsible AI controls — guardrails, content and prompt safety, policy enforcement, explainability, and audit trails — directly into the platform
Manage and iterate on new platform capabilities while balancing the needs of key projects, delivering maintainable, scalable, testable, and easy‑to‑refactor solutions
Work hands‑on and de‑risk the critical parts of our complex projects & Evaluation pipelines. The role will be deeply involved in coding, reviewing, red‑team‑ing, and optimizing AI solutions
Mentor and Drive a Responsible Engineering Culture
Inspire and mentor teams across architecture and engineering disciplines, cultivating a culture of innovation, responsibility, and trust in AI adoption
Drive next‑generation testing, evaluation, red‑team‑ing, and observability practices for dynamic orchestration of user journeys
Establish responsible AI review and evaluation practices — fairness testing, bias audits, safety evaluations, and ongoing monitoring — as a standard part of the delivery lifecycle
Champion a culture of excellence, inclusion, and continuous learning within the team. When something breaks, you're not satisfied with a workaround. You dig until you understand why, and you bring learning and long‑term solutions back to the team.
Skills
Proven experience in AI leadership and delivery roles, with a track record of successfully leading and delivering AI projects — scoping ambiguous problems, communicating trade‑offs, and iterating based on real‑world feedback
Demonstrated experience embedding Responsible AI principles (fairness, transparency, accountability, privacy, and safety) into production AI/ML systems
Extensive experience in Python and its core data science libraries (e.G., Scikit‑learn, Pandas, NumPy, Matplotlib/Seaborn)
Hands‑on experience building and taking LLM‑powered applications to production (retrieval, agents, structured outputs, prompt safety) with appropriate guardrails and evaluations
Experience with Agentic AI frameworks and designing multi‑step AI reasoning processes, including safety, guardrail, and human‑in‑the‑loop design
Experience with MLOps principles and tools for model versioning (e.G., Git), containerization (e.G., Docker), and continuous integration/continuous deployment (CI/CD) of machine‑learning models
Familiarity with model risk management and AI governance frameworks (e.G., SR 11‑7, NIST AI RMF, EU AI Act) and the ability to operationalize them in engineering practice
Proven experience in automated testing and the ability to develop test strategies and design automation frameworks, including evaluation and red‑team‑ing for AI systems
Experience with running benchmarks at scale for model development and evaluation
Strong experience in full‑stack fundamentals, system design, and integrations, with demonstrated leadership in designing and managing low‑latency microservices at scale with authentication and authorization (OAuth 2.0, OpenID Connect, and SAML).
Preferred Qualifications
Strong theoretical and practical knowledge of classical machine learning algorithms (e.G., classification, regression, clustering, dimensionality reduction) and their applications in areas such as fraud detection, credit risk scoring, or customer segmentation
Experience with explainability and interpretability techniques (e.G., SHAP, LIME) and bias/fairness assessment tooling
Experience in fine‑tuning LLMs, embedding models, and tackling advanced RAG or agentic use cases. Building pipelines and eval sets to benchmark performance of such solutions is essential.Demonstrated expertise in feature engineering, feature selection, and data transformation techniques for structured and unstructured data – Experience in designing AI observability, monitoring systems, feedback loops, drift detection, and trend analysis
Familiarity with Google's Vertex AI tech stack
Experience building applications with modern web component frameworks (such as React & Angular)
Experience with containerized tooling and cloud platforms (particularly Docker/Docker Compose, Kubernetes, and GCP)
