Snr Front-end Developer

What You'll Do Does code hold no secrets to you? Are you the go-to expert for your colleagues and do you enjoy taking the lead by setting a good example? Become a Senior Front-end Developer at iO and build excellent applications for top brands like Bol, VodafoneZiggo, and Rabobank.

As a Senior Front-end Developer, you'll work within the in-house teams of leading brands. With your in-depth knowledge and experience, you take the leading role in project teams and are the key contact for clients. They rely on your code, vision, and input as a senior developer. But it doesn't stop there: you elevate other colleagues in the team to a higher level by guiding, motivating, and inspiring them to excel. You ensure that projects are not only technically solid but also contribute maximally to your clients' business objectives. From concept to impact: you're involved throughout the entire journey.

Your team & development You don't just work at the client's site - you remain closely connected with your iO colleagues. At least once a week you come together to catch up, share knowledge, and learn from each other. You'll join a team of experts who will advance your career.

At iO, you get time and budget to develop yourself. Take courses, workshops, training sessions, and earn certificates. Or give presentations yourself, write blogs (check out our Techhub ), and contribute to the Open Source community. We stay at the forefront by participating in many events, conferences, knowledge sessions, and high-level meetups.
