Circularise is a supply chain traceability platform. We help manufacturers collect, verify, and share sustainability data across complex supply chains — and produce the digital product passports, mass balance reports, and compliance documentation their customers and regulators require.
We were founded in The Hague in 2016. Our customers include large manufacturers in automotive, batteries, chemicals, and plastics. The platform lets companies share what they need to without exposing commercially sensitive information.
Regulations like the EU Battery Regulation, ESPR, and CSRD are creating significant new requirements for manufacturers, which means a lot of product work ahead of us.
We’re looking for a product engineer who is comfortable with both front and back end programming, and wants to be involved in the full scope of what gets built. This means constantly improving our supply chain traceability, mass balance, and digital product passport platform, shaping requirements, talking to users, and seeing things through production.
We’re a fast-paced startup in a dynamic industry. Our engineers are required to deliver features from conception to final product, requiring good communication skills, organisation, and attention to detail. You’ll write product specs, make design and technical decisions, and take features from a problem brief all the way to production — with product managers available for strategy and context, but without them driving day-to-day decisions.
In practice, a typical week looks like this: a 15-minute standup each morning, a product and engineering demo every two weeks, and otherwise uninterrupted time to build. The engineering team is small, and we talk directly to customers when needed. Here is what a typical calendar looks like:
