Apply now

We are now looking for a full-time Senior Developer (Golang) to join our RELEX family in our Helsinki office. You’ll join the Optimization team, who will help you succeed in your new role. Together the team is responsible for Workforce Optimization and builds the optimization services used in RELEX Work, which is one of the three main applications within RELEX. This is a great time to join us: you’ll get to have a big impact on how we grow and how we do things.

Our services convert workload forecasts to workforce requirements and then automatically schedule work for our customers’ employees. The goal is to ensure that employees with appropriate skills are scheduled to work at the right time, without violating their contracts. Because of our algorithms employees won’t be burdened with too much work nor have boring idle time, while still getting all the required work done. The optimization services are implemented in Golang and run in Azure. We use git/gitlab for version control and CI. The product is used by some of Finland's largest retailers. You will be working on three backend workforce optimization microservices. You will be a part of a specialist 5person team loosely utilizing Kanban. 

What you’ll be doing:

· Implementing new optimization features in golang

· Doing code reviews, writing documentation, refactoring & bug fixes

· Participating in identifying and designing new features

· Participating in agile team practices and the development of them


What you’ll bring to the table:

  • Good teamwork skills 
  • Excellent communication skills 
  • Experience in writing performant code 
  • Experience with performance profiling 
  • Excellent knowledge of at least one compiled programming language for example Golang, C++, Java, C# 
  • Ability to write clean, maintainable and reliable code 
  • Experience in writing tests 
  • Excellent problem-solving skills 
  • Interest in developing yourself and sharing knowledge with others 

What we consider as an advantage:

  • Familiarity with git 
  • Knowledge of Golang 
  • Knowledge of Python 
  • Interest in the problem domain of workforce scheduling 
  • Interest in optimization and algorithms 


What we offer you in return:

· An international career and learning opportunities in a rapidly growing software company

· A fun, ambitious, and committed team of smart people to work with

· A respectful and professional, yet easy-going atmosphere where individual thinking is encouraged

· Responsibilities in challenging projects from day one

· The option to work remotely part of the time (outside Covid, that is. Currently almost all work is remote)

· Mobile phone, broadband and healthcare benefits

· Plenty of vocational clubs and opportunities: e.g., brewing, orienteering, gym at the office

· Possibility to work on a modern tech stack, e.g., Golang, Azure, Kubernetes, Docker, microservices, CI/CD
