Job Description

Are You The Full Stack Developer Ready To Redefine Our Mobile Experience?

Who we are

Nuli is the top female fitness app in Taiwan. We ignite lifelong transformations through health and fitness

While we are proud of our accomplishments, our journey to make Nuli a fitness household name across Taiwan, Hong Kong, and Malaysia has only just begun.

That’s why we want you to join us as our Mid-Level Full Stack Mobile Developer.

4 Reasons to Join Nuli as our Mid-Level Mobile Full Stack Developer

1. Meaningful Challenge

If you want a cushy role with an impressive-sounding title, we're NOT a match.

If you want to use your expertise to shape the growth of a great, young company for many years to come, this opportunity IS for you.

Nothing worth doing is ever easy. But if you're up for the challenge, let's talk.

2. Freedom to Create

We're looking for someone experienced whose judgment and expertise we can rely on.

Of course, we'll provide suggestions and feedback when we see fit. But we'll trust you to do the job we're hiring you for.

3. We're Just the Right Size

Feeling like just a cog in the wheel is a sure way to build resentment towards any job. The larger the company you work for, the likelier this is to happen.

At under 35 employees, this won't be the case at Nüli. We all take ownership of our work and things never get stale.

At the same time, we're not so small that we don't have enough momentum. And you'll always have plenty of resources at your disposal.

4. Location and Schedule Flexibility

We have a hybrid set-up with the team in Taiwan meeting in person 2-3 times per month. If you’re outside of Taiwan, you can work fully remotely.

Our team typically works 9:00-18:00 Taipei time. But if you want to make any changes to your schedule, we're very open to it.

What We Expect From You

  • Technical Excellence: We anticipate that you will bring a high level of expertise and proficiency in full-stack development, especially with React Native, TypeScript, and Node.js. Your ability to craft engaging front-end interfaces and architect scalable back-end systems will be crucial.
  • Ownership and Leadership: You will take ownership of the projects you handle, navigating complex challenges independently and proactively. We expect you to lead initiatives within your scope, driving improvements and innovations that enhance our app’s performance and user experience.

  • Quality Focus: Championing our commitment to quality, you will integrate robust testing frameworks and adhere to best practices in coding and security. Ensuring the reliability and safety of our app is paramount.
  • Cultural Fit and Ethos Alignment: Embracing our mission to transform lives through health and fitness is essential. We seek someone who is not only skilled but also lives by our Core Values, striving to make a significant impact within the team.
