We are building a Pet Ecosystem that integrates insurance, pet health, and IoT—serving real user needs at scale.
This role is not just about shipping features. You will design systems, influence product decisions, and help define how technology drives growth and user experience.
- Design and deliver production-grade APIs and services powering a fast-growing mobile app
- Own end-to-end features—from system design to implementation and optimization
- Drive architecture decisions across microservices, scalability, and reliability
- Build systems that handle real-world traffic, latency, and edge cases
- Continuously improve performance (API, database, system throughput)
- Establish strong engineering foundations: testing, CI/CD, observability, and security
- Partner closely with Product, Design, App, Data and BE teams to define solutions—not just implement them
- Enable data-driven decisions through tracking, experimentation, and analytics
- Support integrations across mobile and IoT, turning real-world signals into product value
- 5+ years of full-stack development experience with production system delivery
- Strong experience in RESTful API design and backend architecture
- Proven ability to take ownership and deliver end-to-end solutions
- Solid experience in backend development, API design, and database optimization
- Contribute to the design and evolution of Golang-based microservices architecture
- Solid understanding of microservices and distributed system design
- Familiar with Git workflows and code review best practices
- Experience with testing strategies (unit, integration, e2e)
- AI-Assisted Development. Familiar with tools such as Claude Code, GitHub Copilot, or Cursor. Able to integrate AI into development workflows (code generation, refactoring, testing, documentation)
- Experience with Flutter, IoT systems, or real-time data
- Deep understanding of scalable system design and trade-offs
- Experience with microservices or distributed systems
- Comfortable working with performance, reliability, and real-world complexity
- Think beyond code—understand users, business goals, and impact
- Thrive in fast-paced, ambiguous environments
- Proactively identify problems and drive solutions
