React Native Developer

Tech & Product
Amsterdam, NL

About us

Tellow is a fast-growing FinTech company with over 50.000 users, backed by world-class London and New York-based investors Investcorp and Lugard Road Capital. Working from a brand new water-front office in Amsterdam, our talented, ambitious team is committed to giving freelancers full commercial control and assist them with all their financial needs. From accounting, banking, payments and loans, and much more. Tellow is ready to build, innovate and grow. We are expanding our teams and looking for talented people to help us do so.

About the role

By joining our mobile team, you will play a key role in delivering new features to our user base so that they can do their bookkeeping without any friction. You will also proactively keep the mobile application in a good shape, by staying up to date, adding tests, and assertively optimizing wherever the opportunity presents itself (we’re a fan of the boy-scout rule!). You will work in our agile product team with a dedicated Product Lead. We look for people who love coding and problem-solving and are ready to take full ownership of their work. In this role, you are welcome to come up with creative solutions, propose new ideas and be never satisfied with the status-quo!

What you will be doing

As a React Native developer, you will:

  • Implement new features, refactor and maintain our React Native mobile application, so it is reliable, performant, scalable, and good-looking (we are the prettiest bookkeeping tool after all!)
  • Take full ownership of your work, collaborating with back-end developers, designers, and peers to deliver well-architected, high-quality solutions
  • Perform code reviews
  • Write Unit Tests using TDD principles, build and deploy apps with high quality
  • Take part in the agile development process, including sprint planning, retro sessions and daily meetings


  • Love the idea of building beautiful mobile apps
  • Have 1-3 years of provable work experience in software development (junior/mid)
  • Have strong knowledge of JavaScript, TypeScript and React
  • Have experience with React Native
  • Have experience with API integration
  • Have a good knowledge of UI/UX guidelines, frameworks and design patterns
  • Having experience with writing tests is a plus
  • You are pragmatic, dedicated and think of solutions
  • You care about quality. If it’s not the best, is it worth building?
  • You take initiative and are always keen to level up your skills
  • You have excellent English verbal and written communication skills (Dutch not required)
  • You can work from our Amsterdam office (this is not a remote role)
  • You already have or can obtain an EU Employment Permit (EU citizenship). We don’t provide relocation and/or visa assistance for this role.


What is in it for you

  • The opportunity to make an impact, by transforming an old-fashioned bookkeeping industry
  • Working in a trusting environment that entrusts you with crucial company responsibilities to drive your personal growth
  • Be part of a unique, dynamic and fast-growing tech company
  • Working in a work environment that values diversity, inclusivity, teamwork, cohesion, and fun
  • Be part of a talented and extremely driven team
  • Working in a brand new, state-of-the-art office in Amsterdam with a rooftop terrace, balcony and BBQ
  • Working in a healthy workspace with proper climate control, lighting, adjustable desks and 4K screens
  • Free laptop (Macbook Pro or Windows equivalent) and all necessary gear
  • Office lunch freshly cooked (it’s awesome!)
  • Weekly drinks and awesome office events, from roller disco in the kitchen to laser gaming between our desks

Frequently asked

Who can I turn to if I have questions throughout the recruitment process?

You are always welcome to reach out to HR and Talent Acquisition if you have any questions about our recruitment process, an open position or more generally about working at Ageras Group.Phone number: 31791715

What do Ageras Group look for in a potential candidate?

At Ageras Group, we don’t have our mind set on an “ideal” candidate. Instead, we aim for diversity in all aspects, and are proud to be represented by employees with all possible professional and academic backgrounds and with 19 different nationalities. However, what we all do have in common (and what we also would like to see in our next employee) is that we thrive in an everchanging environment and always strive to do better.

What does your recruitment process look like?

A recruitment process at Ageras Group will most often look something like this:
Quick telephone screening – 1st interview – Assessment – 2nd interview - Hire
Read more about the 1st and 2nd interview below.

How should I prepare for a 1st interview?

If you are invited in for a 1st round interview, it’s because you have made a great first impression! Now we just want to get to know you better, and equally important - give you a chance to get to know us. The best advice we can give you is to be yourself. We will probably come well around your CV, but we would also like to know who you are when you are not at work. Maybe you have some cool hobbies, a totally unrealistic dream in life or an impressive party trick? Also, remember that we are here to answer all your questions as well. So fire away!

How should I prepare for a 2nd interview (/test-feedback)?

By now, we have must likely spoken a couple of times and hopefully feel that we know each other relatively well. For this 2nd interview, however, we will use the assessment you have done as a basis for dialogue about your approach to work and your professional behavior and mindset. Our goal is to come around your preferences, development areas and strengths so that your potential new manager will know how to create the best possible conditions for you and your employment.
In other words, we don’t expect much preparation from your side, expect for a bit of reflection about the above.

How should I dress for an interview at Ageras Group?

Dress as you! At Ageras Group, we don’t really have a dress code. Some like sneakers and hoodies, while others are more comfortable in a crisp shirt and polished shoes. Wear what you feel comfortable and confident in – so will we.

Can I apply for more than one job?

Sure thing! If there’s more than one job you could see yourself in, then that’s great! Just remember to express why this exact position is (also) the right match for you.

When can I expect to hear back from you after I have applied for a job?

We respect the time you have put into applying for one of our jobs, and do our best to get back to you as soon as we possibly can. Sometimes we manage get back to you within a couple of days, other times after a couple of weeks. However, you can always trust that we will get back to you within a maximum of four weeks.

Regardless if we see you as a good fit or not as the best fit this exact time around, you will ALWAYS hear back from us.

How long are vacancies open for applications?

We rarely operate with application deadlines. Instead, we keep each position open until we have found the very one. However, as a rule of thumb, you can expect a vacancy to be open for at least a couple of weeks.

What if I’m currently not based in the location for the job I’m interested in?

Awesome! We welcome applicants from all countries with a working permit in the country where the job is localized. Currently, we are proud to be represented by 19 different nationalities, and would love for the number to be even higher!

If you are invited to a physical interview in another country than you are currently residing in, we will of course reimburse all costs related to travelling.

In terms of relocating, we are not able to offer any relocation package, but will be happy to put our expertise at your disposal and help as much as we can.
