About the Role

Riskified is seeking a Senior AI Engineer to join a talented and fast-moving AI Engineering team. We're the central hub for AI across Riskified, driving innovation and putting AI to work for every team and product in the company.

AI already plays a foundational role in how Riskified operates. It lets us ship features quickly and at scale, equips non-technical team members with tools that boost their productivity, and underpins much of the innovation happening across the company today.

What You'll Be Doing

• Design, build, and maintain reusable AI capabilities — spanning models, tools, APIs, and platforms that support both internal operations and customer-facing products.
• Develop and maintain our internal MCP server, giving AI agents easy and secure access to Riskified's extensive data stores.
• Create and implement rigorous evaluation frameworks and AI guardrails to protect Riskified's value and ensure model reliability.
• Cultivate deep expertise and establish sustainable AI engineering practices across the organization.
• Champion AI readiness and track adoption company-wide to build lasting impact.
• Build and optimize RAG (Retrieval-Augmented Generation) systems.
• Own projects end to end — from gathering requirements from non-technical stakeholders through development, deployment, and ongoing operation.
• Serve as a consultant and advocate for AI engineering, guiding other teams in leveraging the platforms and tools you create.
• Collaborate with teams throughout Riskified to accelerate AI adoption and productization.

Qualifications

• 5+ years of solid backend and server-side development experience, building complex and highly scalable systems.
• Proven proficiency in at least one general-purpose language (Python preferred, though not required).
• A natural collaborator who builds trust across functions — comfortable working with product, business development, account management, and other non-technical partners.
• Strong product-oriented thinking, with the ability to elicit, refine, and prioritize requirements from non-technical stakeholders.
• A deep sense of ownership, some DevOps experience, and the drive to develop, deploy, and operate projects from start to finish.
• A bias toward driving change: you spot opportunities to improve processes and accelerate technology adoption, and you act on them.
• High proficiency with AI-assisted coding tools such as Copilot, Cursor, or equivalents.
• Hands-on experience with public cloud platforms (AWS, GCP, or Azure).
• Fluency in written and spoken English.

Bonus Points If You

• Are experienced with agentic coding tools like Claude Code or Copilot CLI.
• Have familiarity with Strands Agents (or comparable agentic frameworks), RAG architectures, and Bedrock.
• Have worked with MCP (Model Context Protocol).
• Are comfortable operating in containerized environments.
