We are looking for a full-time Senior Backend Developer (Elixir) to join our RELEX family at the Helsinki office. You will join the Shift Management team, a team of dedicated developers who will help you succeed in your new role. 

Shift Management is one of the development teams engineering RELEX Work. RELEX Work, a solution of RELEX’s cloud-native Living Retail Platform, is our solution addressing workforce optimization and management. Our team is responsible for two main areas: Core services and Planner UI. Core services is the backend and API that connects several RELEX Work microservices. Planner UI is used by customers to plan and manage the workforce. 

We strive to build a world class, forecast-based workforce optimization SaaS that allows reducing labor costs while simultaneously increasing service levels. You will help us achieve this goal by building the solution that allows effective work shift planning by utilizing workload forecasts and running shift optimizations. 

What you’ll be doing: 

You’ll become part of the backend development team with focus on building Core services in Shift Management. 

  • Develop new features and refactor existing logic (we use Dialyzer and Credo for static analysis and quality control) 
  • Inspect and fix bugs (we use Sentry and DataDog for monitoring and logging) 
  • Write automated tests (we use ExUnit for unit testing and Cypress for end-to-end testing) 
  • Review merge requests (we use GitLab) 
  • Participate in designing concepts and features from early on (we use Miro, Mural among other tools) 
  • Write specs and documentation (we use Confluence and Jira) 
  • Collaborate with product owners and other development teams to design solid and scalable technical solutions (we use Slack and Teams for communication) 

What you’ll bring to the table: 

  • Several years of experience in software development 
  • Experience in functional programming
  • Appreciation towards clean and maintainable code and reliable software 
  • Experience working in an agile software development team (we use Kanban) 
  • Good written and verbal English language skills (our language of communication is English) 

What we consider as an advantage: 

  • Experience with Elixir/Phoenix and PostgreSQL
  • Interest towards learning new things and sharing knowledge with others 
  • Diversity and different perspectives 
  • Full-stack experience (we use TypeScript and React in the front-end) 
  • Experience with cloud services (Azure, K8s, Terraform) 
  • Interest in domain-driven design 
  • Desire to put an end to stupid things. Raise your hand when you see something that does not make sense or could be done differently. 

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 
  • Flexibility to position yourself based on interests and desire to develop your skills 
  • A position at a company that has been doing well despite the global pandemic 
  • Flexible working hours and freedom to decide to what extent you prefer to work remote/on-site (you’ll need to be resident in Finland or willing to relocate) 
  • True continuous deployment 
  • A technology driven environment that allows developers to take responsibility and have a say in decisions being made
