Senior Full-stack Developer

We are looking for a senior full-stack developer to be responsible for developing demanding digital products and services.

We are looking for an experienced full-stack developer with experience in most of the following technologies: JavaScript/TypeScript, React, Angular, Node.js, Heroku, AWS, Google Cloud, WordPress. These are complemented by custom solutions ranging from Enterprise products to custom interfaces and integrations, as well as client-specific content management systems (such as Contentful, CoreMedia, or WordPress), and eCommerce platforms (such as Shopify, WooCommerce).

We appreciate it if you have a consultative approach to client work and are interested in working on a variety of online platforms as well as versatile and business-critical concepts. We work in both Finnish and English and hope that you will be able to communicate in the client interface with both languages.

Our way of working

  • We create new and innovative services for different digital operating environments, we succeed and learn new things in every project, cooperating both internally and with the client

  • In each project, we consider the client's business needs and select the best tools and technologies accordingly

  • We work flexibly in different configurations, whether in Frantic project teams, as part of the clients’ in-house team, or in the clients’ multi-vendor teams

  • Nobody is left alone with their problems – you will be supported by our tightly-knit competence communities

  • We build and nurture an inclusive work culture that values ​​equality and diversity

Quotes from our Full-stack Developers:

“I develop front- and back-end, and I like doing both. My projects are mainly online services, eCommerce, or parts of them. At the moment I’m working on a project, where I’m creating a dynamic and accessible form for an existing online service, plus some CRM and payment integrations in the back-end. Here we get to do demanding, but rewarding things!” – Senior Developer

“I’m a back-end focused developer, and I do data models, logic, and integrations for our clients’ online services. Sure, I’ve coded Angular and React, but as I’ve gotten to work here with much more visually oriented developers than me, I’ve mainly focused on the invisible side of user experience. I’m especially motivated by the large numbers of users and business-critical services that we get to do at Frantic.” –Solution Architect

“As a full-stack developer, I build online services that are customized to our clients' business needs, using modern JavaScript libraries, microservices, and integrations to different systems. Typically, we use either WordPress or Contentful for content management.” –Senior Developer
