Who We Are
At OrderYOYO, company culture comes first. We create a positive, inclusive environment where people are trusted to do their best work and take ownership of what they build. Personal development is central to how we work — engineers are encouraged to grow technically, take responsibility, and help shape how our products and platforms evolve. We help restaurants succeed online by providing branded websites, mobile apps, and tailored marketing solutions, giving them full control of their business.

- Implementing webhook and event-driven payment flows
- Ensuring PCI DSS awareness and secure data handling practices
- Delivering features end-to-end across backend and frontend
- Building and maintaining secure REST APIs
- Owning the full lifecycle: discovery → implementation → release → monitoring → iteration
- Writing secure, scalable, and maintainable production code
- Contributing to architectural decisions around payment reliability and resilience
- Mentoring engineers and raising engineering standards

- Experience designing APIs and integrating third-party systems
- Ability to work independently with high accountability and ownership
- Clear communicator across product, design, and stakeholders
Nice to Have
- Experience in high-transaction or fintech environments
- Experience with queues or event-driven systems
