Reaktor's tech community is looking for an experienced Senior Fullstack Developer to join one of our Business Units in Amsterdam.
If you are comfortable working across modern web applications, backend services and production systems, enjoy solving ambiguous
problems with clients, and are curious to work in a low-hierarchy environment, you might just be what we’re looking for.
You will support clients across a range of digital product, platform and service domains. The exact client context may vary from
focused product teams to large international companies working on high-traffic, business-critical services.
Many of our clients are technically mature and expect a high level of expertise from our consultants. This means you will need to
be hands-on, pragmatic and comfortable helping both the client and the team make good technical decisions.
analytics, content, online stores, integrations, developer tooling or SDKs
We do not have a hard requirement around years of experience, but we have noticed that this level of fullstack, client-facing and
production ownership usually takes several years of professional experience to build.
content, martech or similar product domains
Willingness to work in a hybrid setup. This means balancing office, client premises and remote work depending on the client
project and team needs.

This role is ideal for someone who has experience shipping real-world apps, and is looking to make high-impact technical decisions in a fast-moving team.

Restaurants and other merchants use various software systems such as Point of Sale (POS), Reservations, Kitchen Display Systems (KDS), Payments, Inventory, Staffing, and the list goes on. These systems all need to speak to each other which they frequently don’t. It’s a mess, and we are fixing it.

How we use AI at Tebi We use AI the way our merchants use Tebi, to cut out the friction and get to what matters faster. We believe in a world where AI increases quality, efficiency and speed. At Tebi, AI isn't a policy or a checkbox, it's just part of how we work. It helps us write, analyse, build, and improve but doesn’t make the last call. If there's a smarter way to do something, we want to find it.
