Job description

WealthPark is looking for a backend engineer who can accelerate architecture replacement with high ownership. WealthPark is providing SaaS business for over 3 years. We have some core legacy products. We are planning architecture replacement from a monolith to a microservice basis.
WelthPark has 2 major expectations about this position.

1) Capability to tackle our legacy products(PHP/Ruby).
To maintain or replace our legacy products require persevering efforts. In some cases, our documentation is not perfect, or to resolve issues, engineers need to dig into code deeply. We are looking for a person who is willing to make an effort. WealthPark doesn’t underrate this kind of effort. Some legacy products are our business core. With those products, our business is running properly.

2) Continuously learn new technologies and find ways to solve issues and requirements(Go).
On the other hand, WealthPark would like to recreate architecture from legacy into modern for expanding our business and realize our mission. For contributing to the new architecture, WealthPark is also expecting a person who continuously learns new technologies and finds ways to solve issues and requirements. From a programming language perspective, we are planning to use Golang mainly. But WealthPark is a very flat organization and team. So you can also suggest architecture and tech stacks as you want.
We think a person who can realize the above 2 expectations can accelerate replacing architecture from a monolith into a microservice basis.
