📋 Description

• Be part of a small, dedicated squad within the Channels and Platform team responsible for Public API development. • Lead the development of the backend systems for the Buffer Platform. This includes creating an API for core Buffer features, internal services to ensure Public API stability, availability, high performance, and developer tools for platform clients. • Improve and evolve our internal systems — helping consolidate services into a monorepo, improve tooling and observability, and reduce complexity across the board. • Collaborate closely with engineers, product, and design to scope work, explore trade-offs, and find the simplest path to something great. • Make steady improvements to performance, reliability, and data modeling, helping us scale quality over time. • Participate in on-call rotation (all engineers take on a 24/7 week-long shift once a quarter on average) and day-to-day maintenance work required to keep the lights on the systems owned by the team (this includes bug fixing, addressing security vulnerabilities, incident follow-ups, etc.) • Contribute to shaping our engineering culture by sharing knowledge, reviewing code, and leading by example.
