Posted on Wednesday, April 26, 2023
How will you be able to make a big impact in this role?

In the integration space, you will be the first to join us and build high-quality integrations between our own SaaS and our customers' software systems. 

Actually, the integrations you would work on ensure the effectiveness of our entire business idea: at Circularise we build software that removes data silos and increases transparency in supply chain information transmission and material traceability. We believe that end-to-end traceability holds the key to overcoming major challenges that today’s society faces in areas such as Circular Economy, Environmental Pollution and Carbon Emissions. 

Leveraging our software through these integrations is an important part of our customers' strategic goals, too. Usually, our customers are high-impact enterprise companies in the chemical space. They operate at some point of the supply chain of, for example, the oil, car or battery industry. 

By integrating their software systems to ours, they can ensure they remain compliant with different regulations, and have access to quality data so they can make better informed decisions. Ultimately this helps our customers to reach their sustainability targets, increase recyclability and circulation of materials. What is more, this is very important to high-value brands as well: how to back up their statements and create trust with their consumers? With our software, the brands can create transparency in their sustainability statements upstream the supply chain, and communicate about them openly.

Therefore, integrations play an important role for our entire mission. In this role, you essentially help our customers to bring traceability to global supply chains and to accelerate the world's transition to a Circular Economy.

Key responsibilities in this role

In this role, you will take responsibility for the implementation of the integration solutions: developing and managing the integration of the Circularise tools into third party systems such as ERPs or any other supply chain related software. You will work closely with our customers’ IT Technicians and Enterprise Architects – building good relationships with them and managing contracts related to the integration activities. 

You will also work closely in collaboration with our own Backend, Ops, and Security engineers – tracking the change requirements and translating them into tasks for our team. Our own team works in a very autonomous way – enjoying working on complex and challenging topics, and rolling up their sleeves in our fast-paced startup environment.

Highly knowledgeable about Circularise’s API functioning, our customers’ needs and the business requirements, you would take care of:

  • Designing, developing, and modifying software systems integrations plans, using industry best practices and bringing your insights on these
  • Writing and deploying scalable and robust integration scripts
  • Directing software system integration or data flow testing and validation procedures, programming, and documentation
  • Developing and maintaining data integration components
  • Keeping track of the integration projects

It is surely an exciting time for you to join us! But another reason would be our team. We are a truly culturally open and diverse organization. Our team members are an extremely diverse group of people from over 23 different countries, speaking even more different languages. We assure you, your future team members have so many interesting stories you can learn from. We would describe ourselves as a hungry, humble and smart bunch. Hungry to do, learn and create an impact.
