Bonsai, now part of Zoom, builds tools that help agencies and professional teams focus on meaningful work. We are looking for a Senior Software Engineer to build backend systems and APIs that power proposals, contracts, invoices, payments, time tracking, and projects. Make complex workflows seamless, reliable, and performant.

Work with Product, Design, and Frontend teams to shape architecture and implementation. Own your code, your services, and your impact. Influence a product used by teams around the world. Join a team that combines startup energy with Zoom’s scale. Your work will help small businesses focus on what matters — not busywork.

From small studios to growing global teams, we design tools that remove friction across proposals, contracts, projects, time tracking, and billing. Together with Zoom, we build smarter systems, collaborate more freely, and help shape the future of work.

Responsibilities

  • Leading development of resilient backend systems powering proposals, project management, CRM, invoicing, payments, contracts, and time tracking.
  • Designing and implementing RESTful APIs and microservices that scale with usage and integrate with internal and external systems.
  • Collaborating with Frontend, Product, and Design to deliver reliable, performant full-stack experiences.
  • Driving performance optimization, security hardening, and operations best practices across backend services.
  • Contributing to architectural discussions, system design reviews, and long-term product strategy.
  • Implementing automated test coverage, CI/CD pipelines, observability, and production monitoring.
  • Supporting multi-region, multi-currency, and internationalization requirements as Bonsai expands globally.

What we’re looking for

  • Apply deep proficiency in Ruby, Ruby on Rails, React and Typescript.
  • Design and implement REST APIs and database schemas, ideally using PostgreSQL or similar relational stores.
  • Collaborate effectively with Frontend and Product teams to deliver end-to-end solutions.
  • Ensure system performance, reliability, security, and observability best practices are met.
  • Develop SaaS products; experience with payments, invoicing, or workflow systems is highly advantageous.
  • Operate independently in teams with high autonomy and ownership expectations.
  • Contribute to technical leadership and mentorship across the engineering organisation.
