Principal Technical Program Manager, AWS Mantle

Are you a strategic technical program leader who thrives in high-ambiguity environments where the problem itself may not yet be defined? We are seeking a Principal Technical Program Manager to drive the delivery of significantly complex, cross-organizational programs for AWS Mantle-the next-generation distributed inference engine powering Amazon Bedrock. In this role, you will operate with complete independence across VP organizations, defining program strategy, driving clarity where none exists, and making trade-offs between business opportunity, resources, and long-term sustainability. Your work will be strategic in nature, shaping how we scale AI inference infrastructure to serve millions of customers globally.

• Define and own very large programs spanning multiple engineering teams, product organizations, and VP orgs-driving cross-functional alignment on Mantle"s most critical technical initiatives
• Operate in deep ambiguity where the business and architectural strategy may not yet be defined; drive clarity and create the path forward
• Identify risks and opportunities in technical strategies, architectures, and engineering organization structures, influencing decision-makers at the VP level
• Make strategic trade-offs between business opportunity, resource allocation, and system sustainability while remediating critical and endemic problems
• Effectively force-multiply across the Mantle organization-accelerating delivery, managing escalations, and aligning teams toward simple, coherent approaches

Key job responsibilities

As a Principal TPM on the Mantle team, you will be the strategic connective tissue across our distributed inference platform-orchestrating the delivery of programs that span model onboarding, capacity management, security architecture, and global API availability. You will not simply manage timelines; you will define missions, set objectives, analyze data, and influence resource allocation at the highest levels.

• Own end-to-end program strategy for Mantle"s most complex cross-organizational initiatives, including global model onboarding pipelines, Zero Operator Access security programs, and multi-region capacity scaling
• Drive technical architecture discussions with Principal Engineers and SDMs, identifying dependencies, scaling factors, boundary conditions, and risks across distributed systems serving ML inference at global scale
• Represent and advocate for customers during executive-level prioritization and planning, owning roadmap strategy and ensuring programs deliver measurable outcomes
• Create and optimize cross-org structures and mechanisms that align teams toward coherent delivery approaches-eliminating unnecessary process and streamlining execution
• Actively develop the TPM community through mentorship, promotion assessments, and raising the bar on program management excellence across Amazon Bedrock
