POSITION SUMMARY We are the Platform-as-a-Service Engineering team at EarnIn. We build the foundational "Paved Road" that enables our product teams to ship with velocity and safety. Our stack is built on AWS, EKS, and ArgoCD, but our future is Agentic. We are shifting from manual configuration to AI-augmented orchestration, in which the platform anticipates developers' needs and self-heals through intelligent automation. We're seeking a Staff Platform Engineer (I5A) who is a strategic leader and AI-native architect. You will set the vision and strategy for how agentic AI transforms platform engineering, architect solutions across Kubernetes (AWS EKS), GitOps (Argo CD), CI/CD (GitHub Actions), and our developer portal (Cortex), and mentor senior engineers to build and operate AI agents that eliminate toil and multiply platform leverage. As a Staff Engineer, you are a thought leader across the organization. You will define the technical direction for agentic patterns, drive company-wide adoption of AI-driven workflows, and establish frameworks and best practices that enable your team and other platform teams to design and deploy production AI systems with confidence. You will architect solutions that turn fragmented workflows into AI-powered golden paths, designing agents to handle incident triage, environment provisioning, config generation, and developer self-service, so engineers across EarnIn can focus on high-value work instead of operational toil. This is a remote position, though it could also be a hybrid role from our Mexico City office as part of our expanding site. EarnIn offers excellent benefits for our employees, including healthcare, internet and cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Mountain View headquarters. Our salary ranges are determined by role, level, and location. We are unable to provide visa sponsorship or immigration support for this position. WHAT YOU'LL DO AI-Agent Architecture and Governance: Design foundational patterns and guardrails for how EarnIn builds, evaluates, monitors, and deploys AI agents in production. Own agent governance, including model selection, evaluation frameworks, safety guidelines, and production observability. Establish infrastructure-as-code best practices for agentic systems, ensuring prompts, tools, and evaluation criteria are versioned, reviewed, and tested like critical components. Strategic Leadership: Serve as architect in agentic cloud infrastructure, establishing best practices for production AI agents. Mentor senior engineers in advanced agentic patterns, LLM integration, and production prompt engineering. Lead cross-functional initiatives with engineering, product, security, and business teams to align agentic AI adoption with company objectives. Platform Operations: Oversee large-scale, high-availability distributed systems on AWS, identifying and solving critical performance, scalability, and stability challenges. Use AI-driven observability and anomaly detection to anticipate failures. Lead the evolution of infrastructure-as-code and automation standards, incorporating agentic pattern recognition and automated remediation into operations. Developer Platform: Shape th
