- Ensuring that we can execute our solutions with the required performance and run times for our largest customers
- Helping our team to grow by taking a role in onboarding new people, sharing the knowledge inside the team and contributing to work planning activities
We’re looking for:
- Minimum of five years of production-quality software development experience with Java or similar language.
- Good knowledge and practice of good software development practices like clean code, testing and code reviews.
- Proficiency in version control tools (git)
- Experience and good understanding of algorithm development, from idea to evaluation all the way to production implementation
- Experience in developing performance critical solutions, and optimizing the performance of these solutions
- Willingness to grow your role outside of individual contributions towards helping the overall team to be successful and productive
- Eagerness to take ownership and drive topics
- Friendly and considerate mindset towards colleagues
- Fluent English communication skills
What we consider as an advantage:
- Deep mathematical knowledge and understanding of algorithms. Especially experience combinatorial optimization and network flow optimization problems is beneficial in this role.
- Experience in leading, facilitating and/or planning software development team’s work and development process
- Understanding of the supply chain planning context, and/or experience from consumer goods manufacturing (CPG) industry
- Familiarity with Unix-based operating systems.
As part of a truly international team, you’ll collaborate across time zones and cultures, driving innovation and achieving shared success. Our Product & Technology hubs are in Finland, Sweden, Lisbon, the UK, and the US, fostering global collaboration.
