Front end Developer

Lumoa is a Helsinki-based technology startup that provides an online service for collecting and analyzing customer feedback using AI and Machine Learning. We are growing at 20% rate monthly. After 1 year, we have signed multiple long-term deals including global companies with multi-billion annual revenue. We are also part of Microsoft Azure Sponsorship Program (BizSpark Plus) and we were granted 120 000€ worth of credits to Microsoft Azure for the next year.

This is truly a rare opportunity and we are looking for a Front End Developer to join us!

We are looking for someone, who already is or can grow to become an important contributor to our online service, who takes pride in his/her work and wants to make sure that things are clean, maintainable, and reliable. You also understand that sometimes we must make technological compromises to make a perfect product for our users.


What the position offers:

+ Try and decide which technologies to use

+ Participate in release and sprint planning

+ Participate in overall software and system architecture

+ Possibility to participate in Product Management and Development (not just technology)

+ Possibility to learn about scalable, highly available and self-healing systems


Technology-wise we can offer*:

+ Lots of latest UI technologies (React, Redux, Sass, Yarn, Webpack, D3.js - just to name

a few)

+ Legacy-free codebase

+ UI sketches made by our excellent Service Design partner (possibility to participate)

+ MongoDB, MySQL, RabbitMQ (more to come soon)

+ Microservices, Kubernetes and Docker-based system architecture


*) We will also provide you a possibility to do a ‘code review’ for our codebase and detailed description of our system architecture before signing the contract - we want you to be sure you know what you will be working with.


Don’t worry if there’s something that does not sound familiar – interest to learn new things is a core value of our company.

If you want to hear more, drop us an email - or even better - let’s meet and have a beer and a pizza (We prefer Putte’s or Pjazza, but just as we like bad jokes, SkyExpress is always an option).
