Job Description
Position Description:
The position is responsible for designing, building, and operationalizing production AI systems across the enterprise. This is a hands-on engineering role: you set architecture and engineering standards for agentic AI, generative applications, and ML platforms; you ship reference systems yourself; and you raise the quality bar for every team that builds on AI.
This role will be responsible for building the engineering system — platforms, patterns, evals, safety controls, reliability, cost, and developer experience — so business domains can adopt AI at speed with highest attention to security, compliance, and production discipline.
What you will drive:
- Enterprise AI software architecture: reference designs for LLM applications, multi-agent workflows, RAG/grounding, tool-use, and hybrid classical ML + GenAI systems.
- Production-grade AI platforms: shared services for model access, retrieval, evaluation, observability, prompt/version management, feature/store integration, and deployment.
- Agentic systems at scale: orchestration, memory, tool calling, human-in-the-loop controls, and safe autonomous workflows across business domains.
- Quality and safety system: evaluation harnesses, red-teaming, bias/privacy checks, policy enforcement, rollback, canary, and incident response for AI services.
- Developer experience for AI: SDKs, templates, CI/CD, golden paths, and inner-loop tooling so domain engineers can ship AI features without reinventing the stack.
- Technical strategy and standards: model selection, cost/latency tradeoffs, data contracts, API design, and architecture review for high-risk AI systems.
- Cross-domain enablement: partner with product, risk, compliance, legal, security, and domain engineering teams to take use cases from prototype to regulated production.
Key Responsibilities:
- Define the technical roadmap for AI software platforms and agentic capabilities, aligned to business outcomes.
- Architect, lead the design and hands on build flagship agentic systems.
- Establish LLMOps / AIOps practices: evals as tests, tracing, cost telemetry, drift detection, model and prompt versioning, and SLOs for AI services.
- Set coding, testing, and review standards for AI-adjacent software — Python and TypeScript services, APIs, data pipelines, and infrastructure as code.
- Build and mentor a high-leverage bench of staff/principal engineers and AI tiger-team leads; operate as player-coach on the hardest problems.
- Partner with security, privacy, risk, and legal to implement responsible AI controls that work in a regulated payments/fintech environment.
- Drive build-vs-buy decisions across foundation models, vector stores, orchestration frameworks, and evaluation tooling.
- Represent engineering in executive forums: translate technical risk, readiness, and investment into decisions leadership can act on.
- Stay current with frontier models and research, but filter aggressively for production fitness, vendor lock-in, and total cost of ownership.
Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager.
Qualifications
Essential Qualifications:
- 12+ years of relevant work experience with a Bachelor’s Degree or at least 9 years of work experience with an Advanced degree (e.g. Masters, MBA, JD, MD) or 6 years of work experience with a PhD, OR 15+ years of relevant work experience.
Preferred Qualifications:
- 15 or more years of experience with a Bachelor’s Degree or 12 years of experience with an Advanced Degree (e.g. Masters, MBA, JD, or MD), PhD with 9+ years of experience.
- Demonstrated track record shipping AI or ML systems that run in production at enterprise scale — not demos or isolated POCs.
- Deep fluency with modern generative AI stacks: foundation model APIs, RAG, vector search, tool-use / function calling, agent orchestration, and evaluation frameworks.
- Expert-level software craft: Python required; strong additional experience in at least one of TypeScript/Java/Go; rigorous testing, observability, and API design.
- Experience designing platforms used by other engineering teams (internal developer platforms, ML platforms, or equivalent).
- Strong systems thinking: latency, reliability, cost, data lineage, identity/auth, secrets, and failure modes of probabilistic systems.
- Proven ability to operate in a regulated industry (financial services, payments, healthcare, or similarly constrained environments).
- Excellent written and verbal communication with executives and with engineers; can write an architecture decision record and a board-ready risk brief.
- Bachelor’s in Computer Science or related field required; Master’s or equivalent depth preferred.
- Experience in payments, commerce, fraud/risk, identity, or large-scale transaction systems.
- Hands-on work with agent frameworks (e.g., LangGraph or equivalent), MCP-style tool protocols, and multi-agent patterns.
- MLOps / LLMOps platform experience (feature stores, model registries, experiment tracking, online/offline eval pipelines).
- Prior ownership of AI governance engineering: policy-as-code, access minimization, PII handling, model cards, audit trails.
- Experience standing up forward-deployed or tiger-team models that embed with business domains.
- Open-source contributions, internal platform adoption metrics, or published technical writing that other engineers actually use.
