Senior Front End Engineer Billy
At Billy we help micro businesses focus on what they do best, by providing simple business administration software. On our platform they can create invoices, subscriptions and integrate their e-commerce platform through our platform API’s. We let them manage their expenses via our web-app or mobile app, and even manage their payroll via our deep integration with Salary. More than 40.000 companies are registered and growing every day.
Who are we looking for?
We're looking for a senior engineer, who wants to contribute to a well architected and functioning web application based on React. You’ll be part of an awesome and experienced team of developers, and you appreciate an open, social team with a very flat level of management. We have half our team located in Gdansk and the other half in Copenhagen, and all feature teams work across the offices.
Our web-app is React and Typescript, based on a backend of REST-api’s and React Query to manage the communication. Our design system is documented in Storybook and tested using Chromatic. We release 3+ times per day and believe in small incremental improvements over cumbersome release processes.
To be successful with us, you’ll need a passion for software craftsmanship and product understanding too.
Who you are
A senior front end developer with 3-5 years of experience. We work with end-to-end responsibility, meaning you will be part of a team, who own everything from infrastructure to APIs and front end.
What we ask of you:
- Collaborative: You want to learn from others and see the value of teamwork
- Driven: You are self motivated and driven to improve your coding and team skills
- Responsible: We give a lot of responsibility to our team members, and therefore you like to take responsibility for what you are doing. Ask all the questions, but the task is yours.
- Tech stack: Our Front-End is written in React (functional-based) and Typescript. We have our own, internal Design System, fully documented in Storybook, visually tested by Chromatic. For a global state management we use the native Context API approach and react-query to communicate with the back-end. We use react-hook-form for advanced implementation of the forms, so would be nice if you have experience in this area. Styling is mostly done using ths CSS-in-JS approach (Styled Components). We have some parts of the codebase written in Ember; the connection between these two layers is done with Web Components. We also like to use linters, so we have strong eslint and prettier configuration plugged in.
What you'll do
- Solve very real problems for very real customers.
- Create new features based on our existing design system.
- Add new components and elements to our design system to help speed up other developers in the teams.
- Participate in planning and grooming sessions to break features into workable tasks.
- Collaborate with product and design to find the best solutions for problems encountered by our growing base of users
- Use your 10% time on improving things important to you.
- Be a kick-ass colleague and have fun.
Benefits
We hope it’s fine that we take a moment to boast. Because to be honest, we think what we have to offer is pretty great: Our office is located in Wave by Skanska, with a pretty nice view over town. We have all the sodas and red bull you’ll need, and a Playstation too.
We take pride in our work, but we are also serious about fun. Seriously. We meet between the offices a few times per year for social events and team fun.
At Ageras Group, we are on a mission to conquer the world. But who said you can’t have fun along the way?

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.

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.
