Principal Platform Software Engineer (API Development)

Salary: $104,500 - 234,600 per year Requirements:

• Strong backend engineering experience with distributed systems, cloud services, APIs, and production operations.
• Ability to turn ambiguous product goals into precise, testable specifications covering system behavior, interface contracts, constraints, edge cases, and acceptance criteria.
• Experience guiding AI-assisted development with specifications, critically reviewing generated code and tests, and validating correctness, security, maintainability, and architectural fit.
• Full-stack capability with React, JavaScript or TypeScript, and Node.js, connecting frontend experiences to backend services.
• Experience with or familiarity with MCP App Extensions and dynamic AI canvases, including tool-connected interfaces, streaming updates, and interactive AI-generated content.
• Experience designing secure service integrations with identity, authorization, auditability, and policy enforcement.
• Familiarity with LLMs, AI agents, RAG, tool calling, MCP, hosted tools, vector stores, or agent orchestration patterns.
• Experience with OCI, Kubernetes or containers, Java, Python, or TypeScript, service telemetry, and operational excellence.
• Strong engineering judgment and ownership from specification through production validation, with the ability to work across teams and shape reusable platform capabilities.

• Lead cross-team development of backend services, middleware patterns, and runtimes to standardize interoperability at scale.
• Design and build scalable APIs and services for multi-tenant workloads, frontend applications, and AI-powered experiences.
• Establish versioning, deprecation, compatibility, and rollout strategies that limit downstream disruption.
• Set shared observability baselines, including service-level objectives, error budgets, and resilience patterns.
• Own backend performance, capacity planning, reliability, and production troubleshooting.
• Deliver end-to-end features that connect backend services and APIs with responsive, interactive frontend experiences.
• Develop and maintain React applications and reusable components, and contribute to Node.js services and integration layers as needed.
• Build MCP App Extensions and connect their interfaces with tools, platform services, and AI workflows.
• Create dynamic AI canvases for interactive content, visualizations, and actions informed by AI outputs.
• Implement frontend state management, asynchronous data flows, streaming updates, and clear loading, error, and recovery states.
• Work with product and design partners to turn requirements into intuitive, accessible experiences.
• Apply validation, authorization, and error handling across frontend and backend boundaries.
• Translate business and product needs into precise specifications that guide AI-assisted development, defining system behavior, interfaces, constraints, acceptance criteria, and validation strategies.
• Use AI development tools to generate, refine, and test solutions, applying engineering judgment to assess quality, security, maintainability, performance, and architectural fit.
• Lead technical initiatives across teams, resolve ambiguity, and manage dependencies and integration contracts.
• Own outcomes from specification through production validation and ongoing improvement.
