About The Role

WealthPark is looking for a Backend Engineer who can accelerate product development and backend architecture improvements. Over 4 years after we launched, WealthPark’s product has reached a stage where we are continuously improving the product and reviewing the architecture in parallel. We are looking for an engineer who will enjoy this change with us!

WealthPark has 2 major expectations about this position.

Capability to tackle and improve our existing products (Python)
To maintain or replace our existing products require persevering efforts. In some cases, our documentation is not perfect, or to resolve issues, engineers need to dig in 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.

And as a startup, it is also expected to continue to provide new value to users. From this perspective, we also need to modify and improve our existing products. We also expect to use Python on an ongoing basis for data integration and specific purposes. Therefore, we are looking for an engineer with strong knowledge of Python.

Continuously learn new technologies and find ways to solve issues and requirements (mainly go)
In addition to that, WealthPark would like to recreate architecture from the existing app into modern ones for expanding our business and realizing 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 product development and backend architecture improvements.
