Principal AI Platform Engineer

Applied AI | Cloud Platforms | Industrial Software | Multicloud Engineering

Level: Principal / Senior Individual Contributor

Focus: Hands-on Engineering & Technical Leadership

The Opportunity

We are seeking a Principal AI Platform Engineer to design and deliver enterprise-scale AI and cloud platform solutions. This is a highly hands-on technical leadership role combining Applied AI, Generative AI, cloud-native engineering, distributed systems, Azure/AWS, and industrial software.

You will work closely with Product, R&D, Architecture, Cloud Operations, and customer-facing teams to build secure, scalable, reusable, and production-ready solutions.

Key Responsibilities

  • Design and build AI-enabled services, APIs, connectors, libraries, automation, and reusable platform components.

  • Develop production AI solutions using LLMs, Generative AI, RAG, AI agents, orchestration, vector search, grounding, evaluation, safety, monitoring, and cost optimization.

  • Architect cloud-native solutions using C#, .NET, ASP.NET Core, REST APIs, microservices, containers, Kubernetes, serverless, and event-driven architectures.

  • Engineer enterprise platforms across Microsoft Azure and AWS, including identity, data, messaging, API management, observability, Infrastructure as Code, and CI/CD.

  • Design and execute cloud migrations and Azure-to-AWS migration strategies, including networking, data movement, portability, resilience, cutover, and rollback.

  • Troubleshoot complex production issues involving performance, scalability, reliability, latency, security, and compliance.

  • Build solutions involving industrial/OT data, time-series data, historians, SCADA, MES, ERP/EAM, digital twins, and edge-to-cloud integration.

  • Use AI-assisted engineering for code modernization, refactoring, migration, performance analysis, testing, and developer productivity.

  • Provide technical leadership, influence architecture decisions, mentor engineers, and establish strong engineering practices.

Required Experience

  • Typically 10–15 years of relevant software engineering, AI, cloud/platform engineering, distributed systems, or industrial software experience.

  • Strong hands-on expertise in Applied AI and Generative AI, including production implementation of LLMs, RAG, agents, vector search, evaluation, grounding, safety, monitoring, latency, and cost management.

  • Strong backend engineering experience with C#, .NET, ASP.NET Core, APIs, microservices, containers, and Kubernetes.

  • Advanced hands-on experience across Azure and AWS, including compute, Kubernetes/containers, serverless, databases, storage, messaging, identity, secrets management, API management, monitoring, CI/CD, and Infrastructure as Code.

  • Experience with multicloud architecture and cloud migration, preferably including Azure-to-AWS migrations.

  • Understanding of industrial environments such as SCADA/OT, historians, MES, time-series data, ERP/EAM, digital twins, and edge/cloud integration.

  • Strong understanding of secure software engineering, testing, observability, deployment, scalability, performance, release readiness, and production support.

  • Ability to provide technical leadership and influence engineering teams without requiring direct people-management responsibility.

Highly Desirable

  • Experience designing and operating agentic AI systems that automate SDLC activities such as requirements analysis, coding, code review, testing, dependency upgrades, and release preparation.

  • Experience integrating AI agents with source control, CI/CD, and engineering tools, including human approval gates, scoped permissions, auditability, and security controls.

  • Experience deploying AI solutions in regulated, high-availability, industrial, or mission-critical environments.

What Success Looks Like

You will deliver secure, production-ready AI capabilities and reusable platform solutions while improving cloud portability, developer productivity, application performance, reliability, and customer value.

This is a Principal-level technical leadership role for someone who remains deeply hands-on. It is not primarily a people-management position.

Compensation: - $120,000 to $180,000 + this position is also eligible for Cognizant’s discretionary annual incentive program, based on performance and subject to the terms of Cognizant’s applicable plans. Application will be accepted by 11/27/2026
