About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role As a member of the GTM team at Anthropic, you will be a Staff Forward Deployed Engineer (FDE) who embeds directly with our most strategic customers and leads the technical direction of their AI adoption. Customers bring you in to lead, not only to implement: you decide what should be built, and then make sure it gets built well. You will work with customer teams to ship advanced AI applications that solve real world business problems, and guide the architecture and advisory work that surrounds those builds across an account. Working closely with our Research, Product, and Engineering teams, you'll combine engineering expertise, an understanding of frontier AI applications, and customer-facing skills to understand customer workflows and develop innovative solutions that address complex business challenges while maintaining our high standards for safety and reliability. You will sit at the frontier of enterprise AI deployments and help shape our forward-deployed motion as it scales.

At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most. As a Senior Technical Account Manager (Senior TAM, L6) at Affirm, you will own the operational aspect of technical account management across Affirm's strategic alliance portfolio—alerting, monitoring, troubleshooting, delivering against SLAs, fielding technical inquiries, and performing investigations and analysis, while also driving technical initiatives that translate merchant business objectives into technical strategies and product optimizations. Senior TAMs are part of the Engineering team and collaborate closely with Affirm's Product, Engineering, Operations, Customer Success, and Frontline Technical Support teams. This is an operations-heavy role to start. Expect the majority of your early focus to be on keeping merchant integrations healthy—monitoring, triage, troubleshooting, and SLA delivery—while you progressively take on more custom solutioning and cross-functional initiatives. Over your first 6–12 months, as you build operational mastery, you will grow into owning your own book of accounts and carrying it through to end-to-end account ownership. A Senior TAM independently owns operational health across the strategic alliance portfolio, designs custom integration solutions grounded in Affirm's standard integrations, drives cross-team collaboration on initiatives, acts as a technical lead on team projects, and mentors less-experienced members of the team. What You'll Do Own the operational aspect of technical account management across Affirm's strategic alliance portfolio—alerting, monitoring, troubleshooting, and fielding technical inquiries—so integrations stay healthy and issues are resolved quickly. Deliver against SLAs, proactively surfacing technical risks before they become customer-impacting and responding with urgency to merchant issues. Perform in-depth investigations a
