Backend engineer

About the Role:

The Growth Engineering team is responsible for driving customer acquisition and conversion across the entire user journey. We build and optimize experiences that help prospective customers discover our products, book trials, engage with our ecosystem, and ultimately become paying members. Our scope spans both digital and physical touchpoints. On the consumer side, we own critical parts of the acquisition funnel including lead generation, trial booking, onboarding, and conversion experiences. We also power the non-member trial experience at our centers, ensuring a seamless journey from first interaction to membership purchase. Beyond customer-facing experiences, we build backend platforms and internal products that enable center teams to efficiently manage leads, track customer interactions, and improve conversion outcomes. Every feature we build has a direct impact on customer acquisition, business growth, and revenue. We're looking for an SDE2 Backend Engineer who has built and shipped scalable backend systems, enjoys solving product and platform problems, and is excited about leveraging AI to improve engineering productivity and software quality.

What You'll Build

1. Design and build scalable backend services and APIs powering customer acquisition, trial experiences, and membership conversion.

2. Develop microservices that support both customer-facing applications and internal sales and lead management platforms.

3. Build reliable integrations across CRM, payment, communication, and internal platform services. 4. Improve system performance, scalability, reliability, and observability for high-volume production systems.

5.Leverage AI-assisted development workflows and engineering automation to accelerate delivery and improve developer productivity.

6.Collaborate closely with Product, Design, Data, and Business teams to deliver measurable business impact.
