About the role
As a Product Engineer, you can focus on frontend, backend, or full-stack work building the shared systems other teams depend on. The work is guided by a few simple questions:
- Are our shared systems fast, reliable, and cost-efficient as traffic grows?
- Are we making product development safe by default, consistent, and faster?
- Can a builder connect a third-party service once and have it work safely across every app they build?
- Are user-facing surfaces consistent and fast, with shared primitives teams can build on?
- Is our codebase easy to navigate, change, and extend, including for AI coding agents?
Responsibilities
Design reusable primitives and interfaces with clear contracts and documentation that other teams adopt.
Work directly with product teams to turn their friction into platform improvements.
Profile and instrument shared systems, then ship the improvements that move latency, cost, and reliability.
Harden systems against failure and abuse, and make safe defaults the path of least resistance.
Set technical direction in architecture and design reviews, and document the decisions and rollout plans behind them.
Areas you might work in
- Backend infrastructure: the data and service infrastructure the product runs on, including caching, databases, APIs, and the observability that keeps it healthy.
- Connectors: the platform that lets a builder connect a service once (communication, payments, developer tools, cloud storage, CRM, data warehouses, and more) and have Agent read and write to it across every app, without managing API keys. The work spans OAuth, permissions, and multi-tenant infrastructure.
- Product primitives: the building blocks teams reuse instead of rebuilding, such as identity and entitlements, localization, and configuration.
- Frontend platform: the architecture and platform layer behind core product surfaces, including frontend frameworks, the data layer, shared UI primitives, and client performance.
Required Skills And Experience
- Experience shipping and operating software in production (reliability, performance, incidents, observability)
- Built and operated platform systems that other teams depend on
- Able to make and communicate tradeoffs across UX, correctness, delivery speed, and long-term maintainability
- Comfortable collaborating cross-functionally with engineering, design, and product partners
- Fluent in modern web stacks (TypeScript, React, Node.js, Postgres), with depth in frontend, backend, or full-stack
