Job summary

Quo is shaping the way modern businesses connect with customers by unifying calls, texts, and customer data in an AI-powered platform. We are seeking a senior engineer to own the API platform architecture and drive collaboration across product, partnerships, and leadership.

You'll mentor engineers, define long-term API roadmaps, and ensure the system remains fast, observable, and scalable as Quo grows from hundreds to thousands of users.

Qualifications

• You've built or owned a public API, developer platform, SDKs or webhooks for a product people pay for.
• You've driven a big cross-team change at a company with 80+ engineers, by getting the right people in each team on board.
• You've worked through the stage Quo is at now: Series B into growth, 100 to 300 engineers, process being built and rebuilt.
• You're comfortable owning infrastructure alongside application code.
• You communicate clearly in writing and in person, and you're comfortable building rapport across teams.
• 10+ years in engineering with real time at staff level; you've done this job before, at least once.

Responsibilities

• Build the system and relationships that let any team add their feature to the public API quickly and have other engineers adopt it.
• Own the long-term architecture for the API platform; SDKs and code generation from a surface model are on the roadmap.
• Be the technical point of contact for partnerships, product and leadership on API and integrations; protect the roadmap when needed.
• Mentor senior engineers through design reviews, PR reviews and coaching, writing less code by design.
• Keep the platform fast, reliable and observable as traffic grows.
