- Collaborate tightly with Frontend engineers to deliver clean APIs and seamless UI integration.
Backend Development (Golang)
- Design, build, and maintain scalable backend services in Go.
- Develop APIs and service-layer logic for core product flows (trial booking, membership, scheduling, engagement, payments, etc. ).
- Own data modeling and storage patterns using SQL/NoSQL systems (based on current stack).
- Ensure backend services are secure, observable, and resilient (auth, rate limiting, logging, metrics, tracing).
- Improve performance and reliability: reduce latency, optimize queries, handle concurrency safely, and ensure graceful failure modes.
- Integrate third-party tools and platforms (payments, notifications, analytics, video, CRM, etc. ) cleanly and safely.
Mobile Development (React Native)
- Develop and maintain our React Native apps across iOS and Android with a strong focus on stability and UX polish.
- Implement complex flows including navigation patterns, deep linking, background tasks, push notifications, and in-app updates.

- Build smooth, delightful mobile interactions through animations and gestures (Reanimated, Gesture Handler).
- Own performance excellence on mobile: optimize memory, FPS, bundle size, and rendering behavior.
- Manage the practical realities of consumer apps: CI/CD pipelines, OTA releases, store compliance, and version rollouts.
Engineering Ownership & Execution
- Own features end-to-end: understand the user journey, clarify requirements, ship, and follow through until impact is achieved.
- Write clean, testable, and maintainable code with high standards for reliability.
- Collaborate closely with Product, Design, Backend, Care/Sales (as needed) to deliver aligned outcomes.
- Participate actively in code reviewsraising the bar for quality and architecture.
- Investigate and fix real production issues quicklyperformance regressions, crashes, UI bugs, and behavioral edge cases.
- Improve frontend standards, tooling, and developer experience across both web and mobile.

- Build backend systems that are stable under real consumer traffic and edge cases.
- Make pragmatic, time-respecting decisionssolve the right problems without unnecessary complexity.
- Improve reliability/performance and proactively reduce tech debt in high-impact areas.
- Become a trusted owner of major parts of the product and platform.
Required Skills & Experience
- 4+ years of professional software engineering experience, with full-stack ownership in production systems.
- Strong backend development experience, ideally 2+ years in Golang (or equivalent with ability to ramp fast).
- Solid understanding of:
- RESTful API design, versioning, and security best practices
- Service architecture (monolith modularization or microservices)
- Concurrency, performance tuning, and profiling in Go
- Data modeling and database reliability (transactions, indexing, query optimization)
- Caching strategies, background jobs, queues, and event-driven patterns
- Strong frontend fundamentals (React ecosystem preferred), enough to execute full-stack features confidently.
- Experience working with Git, CI/CD pipelines, and cloud deployments (AWS/GCP/Azure).
- Comfort operating in agile/iterative environments with high product collaboration.
