Principal AI Engineer

About the role

We're building a shared AI platform that powers the next generation of our product portfolio - multi-agent orchestration, ML scoring infrastructure, and LLM-powered intelligence products. As Principal AI Engineer, you'll architect this platform, set the technical direction, and define the engineering standards that the organization builds against. This is a hands-on technical leadership role - not a management position. You set architectural direction and write production code every day. You think in ADRs, trade-off matrices, and failure modes. You use Claude Code and AI accelerators to operate at 3-5x speed, and you teach the team to do the same. Your work directly shapes a growing AI product portfolio. The platform you architect becomes the shared foundation - every subsequent product launches faster because of the infrastructure decisions you make now. You'll be based in India, working hybrid (3 days in-office per week), and will report to the VP of Engineering / CTO.

Responsibilities

• Own AI Platform Architecture :
• Design the full AI platform - multi-agent orchestration, ML inference infrastructure, LLM gateway, tool registry, and eval/observability stack
• Write Architecture Decision Records (ADRs) that the organization builds against
• Make build-vs-buy decisions, evaluate emerging frameworks (A2A, MCP, Visa TAP), and define integration patterns
• Design system-level concerns: auth gating, policy enforcement (OPA), API gateway patterns (Kong), and multi-tenant isolation
• Define reference architectures for AI-enabled services across .NET 10 APIs, Python ML workloads, React frontends, AKS deployments, Kong gateway integration, and Azure DevOps delivery pipelines
• Drive Product AI Strategy :
• Partner with Product and CTO office to translate business objectives into AI technical strategy
• Identify where AI creates differentiated value - predictive models, conversational agents, intelligent automation
• Evaluate and de-risk emerging technologies. Present to executive leadership on AI capabilities, costs, and competitive positioning
• Define the AI FinOps strategy: token metering, model routing for cost optimization, quota management, and budget forecasting
• Establish clear platform decision rules for when AI capabilities should be implemented as .NET services, Python services, Azure ML pipelines, background jobs, or embedded product workflows
• AI Safety, Governance and Responsible AI :
• Define and enforce the Responsible AI framework - content safety guardrails, PII governance, bias testing, and audit trails
• Ensure all AI systems meet PCI DSS, SOC 2, and emerging AI regulation requirements
• Establish model validation and governance processes - transparency, explainability, and fairness are non-negotiable
• Build the trust infrastructure that enables the organization to deploy AI confidently in regulated financial services
• Champion ethical AI principles; ensure all agents and models comply with global financial regulations and internal compliance standards
• Write Code - Everyday :
• Write production code, review critical PRs, debug complex agent interactions, and prototype new capabilities
• Lead by example - your code quality, testing discipline, and documentation set the standard
• Use Claude Code and AI accelerators daily. Build custom skills, MCP integrations, and automation workflows
• Mentor and Multiply the Team :
• Raise the AI engineering bar across the organization. Run design reviews, pair on complex problems
• Champion AI-accelerated development - train the team on Claude Code workflows, custom skills, and agentic tooling
• Define engineering standards, evaluation criteria, and best practices that scale beyond your direct team
• Must-Have Qualifications
• 10+ years in software engineering with 5+ years in AI/ML - you've architected and
