Job description

About the role

As a Distinguished Frontier Engineer, you'll help shape the future of enterprise AI. As the senior technical leader who designs the enterprise-scale AI systems behind Cognizant's most complex client transformations, you'll define human-agent capability matrices, author guardrail specifications, lead client architecture workshops, and own the intellectual design of AI delivery at scale, spanning cross-domain, cross-platform and cross-sector work.

From responsible-AI governance to regulated decisioning systems, you'll set the standard rather than meeting it. Partnering with senior client stakeholders, AI leaders and Frontier teams across industries and geographies, you'll establish the frameworks, guardrails and architectural patterns that enable organizations to confidently adopt AI at scale, while technically leading cohorts of Frontier Engineers and Masters and mentoring the next generation of Frontier talent.

• Design AI-native enterprise architectures and define human-agent capability matrices for delivery programmes.

• Author guardrail specifications and boundary documentation for agentic systems at enterprise scale.

• Lead client architecture review workshops and produce context-pipeline blueprints.

• Govern ADLC adoption across the portfolio and define standards for AI-generated code quality.

• Architect responsible-AI frameworks, including bias detection, explainability and audit-trail design.

• Experience with ADLC delivery governance and cross-platform AI integration strategy.

• Skills in frontier-model evaluation and red-teaming, AIOps orchestration architecture and human-agent capability modelling.

These will help you succeed

• Enterprise AI architecture leadership paired with responsible-AI and guardrail design expertise.

• ADLC governance and standards experience across large portfolios.
