• End-to-End Delivery: Take platform initiatives from blank-page research to architectural planning, hands-on execution, deployment, and production monitoring.
• Enable 100+ Engineers: Build standardized developer tools, APIs, and infrastructure that make shipping AI applications seamless, secure, and reliable for engineering teams company-wide.
• Scale & Observability: Design event-driven architectures built for high load, zero-downtime reliability, deep tracing, structured logging, and production observability.
• AI Cloud & DevOps: Manage and automate cloud infrastructure, container execution environments, and CI/CD pipelines to support AI workflows.
• Uphold Engineering Standards: Maintain a clean architecture mindset, promote engineering best practices, and collaborate closely with cross-functional teams to deliver tangible impact.

Requirements

• 5+ Years of Senior Production Experience: Proven track record as a Senior Backend or Platform Engineer shipping software that runs in production at scale.
• End-to-End Execution: Ability to unpack ambiguous problems, perform the necessary research, draw up a solid architectural plan, and execute to completion.
• Architecture & Clean Code Mindset: Deep appreciation for event-driven systems, clean abstractions, Domain-Driven Design (DDD), and high standards for software quality and maintainability.
• Core Technical Baseline: Hands-on experience writing production code in TypeScript (NestJS) and/or Python, along with familiarity with cloud infrastructure (AWS, Docker, Terraform) and microservices.
• Production Craft & Observability: Real-world experience diagnosing production issues, handling scale/load bottlenecks, and implementing robust logging, tracing, and metrics.
• Impact-First & Collaborative: A team player who is passionate about AI, driven by creating real leverage for other developers, and focused on business outcomes.
