Om tjänsten
Reaktor's tech community is looking for an experienced Senior Fullstack Developer to join one of our Business Units in Helsinki.
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.
YOUR DAILY TASKS MAY INCLUDE:
- Working on products or tooling related to customer-facing services, internal platforms, identity, martech, customer support,
analytics, online stores, integrations, developer tooling or SDKs
TO THRIVE IN THIS POSITION, YOU’LL NEED:
MUST-HAVES
- Strong experience in backend service development, for example with Node.js, Java, Kotlin, Scala, Clojure, Python or comparable
technologies
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.
NICE-TO-HAVES
- Experience from customer-facing digital products, online services, ecommerce, subscriptions, internal platforms, analytics,
martech or similar product domains
ADAPTABILITY
Willingness to work in a hybrid setup. This means balancing office, client premises and remote work depending on the client
project and team needs.
