Customer Support Engineer

Who We NeedRillet's support function is new and being built intentionally — and we're building it to scale through engineering, not just headcount. You'll join as one of our first Customer Support Engineers: a hybrid role that combines front-line customer problem-solving with the technical work of building the tools, automations, and AI-assisted workflows that make support fast, accurate, and scalable.On any given day you'll be resolving real customer issues and building the systems that resolve the next hundred. You'll respond to inbound questions, triage bugs, and get customers unblocked quickly — then turn what you learn into knowledge base content, better ticket routing, AI agent improvements, and internal tooling that makes the whole team more effective. You care about fast, accurate resolution, and you find both the support craft and the engineering behind it energizing.This is a role for someone who thinks beyond closing tickets one at a time. You see a repeated question and want to automate it away. You see a manual triage step and want to build a workflow for it. You want to compound your impact over time, not just keep pace with volume.We're looking for teammates who value in-person collaboration and are within commutable distance of our San Francisco (preferred) or NYC offices (or willing to relocate). Team members are required to work in-office Tuesdays and Thursdays, plus one additional flexible in-office day. Certain roles may require additional in-office time based on function.
