About the position
As a Senior Frontend Developer at Sitly, you'll work on our frontend systems, building scalable features and improving the user experience for both parents and sitters. We're specifically looking for someone with strong Angular experience.
You'll join our small, experienced stream aligned team, where every developer plays a key role. You'll write high-quality code, contribute to technical decisions, and bring your own perspective to improve how we work. Your input will help shape how we build our product.
What your responsibilities would be
Build and improve features on our Angular frontend
Write E2E tests for new features
Spot bugs and suggest improvements proactively

A typical day at Sitly
It's Thursday, one of the two days you work from the office. You arrive at our office at the Rokin just across the metro station in the centre of Amsterdam. You grab a coffee before the team stand-up begins. Some of your teammates join remotely, while others are there in person. You share what you've been working on and sync on priorities for the week. You're currently building a new frontend feature to improve sitter-parent communication, and you plan to pair up later with your onboarding buddy for feedback on your implementation.
After the stand-up, you catch up with the product owner and team lead, who also work from the office for the same couple of days a week. Together, you review an upcoming feature and share your ideas on how to prioritise a few technical improvements. You bring your own perspective on how to enhance the platform. Your suggestions are well received and included in the implementation.
Around noon you enjoy lunch (based on your dietary preferences) together with the team. You all take your time to connect, if the weather allows heading up to the rooftop terrace for a coffee and some fresh air.
In the afternoon, you continue working on your feature, write tests, and pick up a code review request from a teammate.
What we're looking for
The mindset and approach we value:
You're humble, collaborative, and happy to ask for input when you need it
You take initiative and find practical solutions without lots of support
You help keep the team moving forward, not just your own work
You actively seek feedback and use it to improve
You like testing new approaches and see failures as part of the process
The experience and skills you bring:
You are a seasoned frontend developer with experience delivering features end to end
Expert in Angular
Proactive: you take initiative, suggest improvements, prioritise, and take ownership
Strong grasp of clean code, best practices, and scalable systems
Fluent in HTML, CSS, JavaScript, and familiar with CSS preprocessors
Solid experience with Git workflows
Experience with API development
Bonus: experience with Cloudflare or ELK stack
Fluent in English, written and spoken
This role might not be for you if …
You prefer a clearly defined role and development process; at Sitly, scope, teams and priorities evolve as we grow

About Sitly & the team
Sitly started in 2012 and has become one of the largest international marketplaces that connects families with babysitters, nannies and childminders, making flexible and affordable at-home childcare possible. Sitly is live on web, iOS and Android app, and has millions of registered families, babysitters, nannies and childminders in 20 different countries across Europe, Asia Pacific, North and South America. Overall we have over 700 thousand monthly active parents and sitters on our platform.
We pride ourselves on being an independent, profitable tech company that has never had to raise any funding. We get up in the morning to improve the experience for our users, and to keep growing fast. One part of our small team (45 people) is working from our office in Amsterdam, and the other part remotely around the world. We have to be smart about what we spend time on: we focus on the basics, while at the same time rapidly and radically testing new ideas.
We are a diverse team made up of 22 nationalities and a culture of independence, getting things done, and being humble while doing so. We focus on growth, but never lose sight of what is most important: providing a trusted childcare platform that instantly connects parents and babysitters in their local area.
