The Senior Full Stack Engineer will drive cross-product impact by building experiments in Proposals, optimizing onboarding flows, and developing features that impact acquisition, monetization, and retention metrics. They will operate in a Kanban environment, balancing rapid iteration with quality engineering practices, and own end-to-end user journeys from signup to subscription upgrades. Responsibilities include pioneering AI-driven experiences and workflows, leading with autonomy in a self-directed environment, and building with experimentation in mind by setting up A/B tests and prototyping new experiences.
