Principal Software Engineer - Product Platforms

You'll define and build shared, API-first product platforms that power multiple product surfaces, integrations, and agentic workflows. You'll focus on building platforms as products with well-designed APIs, clear contracts, strong reliability guarantees, and a roadmap driven by real product needs. You'll stay close to the code while shaping how product platforms are designed, evolved, and adopted across the company, working across multiple teams and domains while still owning end-to-end systems. You'll enjoy building, prototyping, iterating, and solving complex problems in production.

Responsibilities

• Act as a technical owner and force multiplier for API-first architecture across the company
• Design, build, and evolve high-scale APIs used by internal teams, external customers, and intelligent agents
• Lead the development of agentic workflows, including orchestration, state management, tooling, and integration patterns
• Drive API standards, design principles, and best practices through hands-on work and technical reviews
• Tackle complex cross-team problems where requirements are ambiguous, and constraints are real
• Partner with Product, Platform, and SRE teams to ensure APIs are reliable, observable, secure, and scalable
• Identify and reduce systemic technical risks while enabling teams to move faster
• Mentor senior engineers and raise the technical bar through example, not hierarchy

Requirements

• Extensive experience as a senior staff/principal-level software engineer working on applications and backend systems
• Experience building product platforms or shared services consumed by multiple product teams
• Proven track record of designing, building, and operating APIs at scale
• Strong hands-on experience with RESTful APIs
• Some experience with GraphQL (design, usage, or operating in production)
• Deep understanding of system design, performance, reliability, and evolution over time
• Strong bias toward hands-on contribution and ownership of real systems
• Ability to influence technical direction across teams through credibility and execution
• Experience building or enabling agentic or AI-driven workflows (nice to have)
• Familiarity with MCP (Model Context Protocol) or similar agent integration patterns (nice to have)
• Experience working in large-scale, distributed systems environments (nice to have)
• Exposure to API governance, versioning strategies, and backward compatibility at scale (nice to have)
• Experience working closely with the platform and SRE teams (nice to have)
