Senior/Staff Backend Engineer

You'll have the opportunity to define and evolve our backend architecture as we rapidly scale, directly impacting our growth. We're a senior team that values craftsmanship, and you'll play a crucial role in mentoring future engineers as we grow. As a Senior/Staff Backend Engineer you will scale and evolve backend systems that manage hundreds of millions of participant records. You will own and mature critical infrastructure such as email/SMS delivery, data syncing pipelines, search APIs, and workflow automation.

You will drive the evolution from 1→10, improving existing services to handle greater scale, tighter reliability requirements, and deeper product integration. You will collaborate cross-functionally with design, marketing, sales, customer success, and the founding team to shape product direction and ensure engineering is aligned with user needs and business goals. You will lead with technical vision, identifying opportunities to reduce complexity, improve developer experience, and guide architectural decisions that support long-term growth. You’ll design reusable systems and clear abstractions that power future products.
