In today's digital age, instant information is the norm. But this transparency disappears when it comes to consumer products, and their ethical and sustainable production through supply chains. Addressing the global climate challenge and safeguarding both humanity and the planet requires a transformation in food systems. This is why we built OpenSC. Co-founded by WWF and The Boston Consulting Group, OpenSC is on a mission to revolutionize the way we buy and produce products by providing data on transparency and traceability for supply chains. We deliver social and environmental impact by providing supply chain transparency that empowers brands to know, influence, and prove (to third parties) the sustainability of their supply chain practices. This is achieved through the OpenSC platform, which leverages AI, Blockchain and Remote Sensing technologies to enable automated ingestion, analysis, and sharing of a supply chain's data. Drive an innovative product idea that directly impact customers by developing and optimising the platform and creating a smooth and pleasant end-user experience for our customers. Collaborate on designing, developing, and scaling the OpenSC platform, driving its global rollout across diverse supply chains. Design and build secure, scalable, and reliable web applications based on Python and Spring Boot (Kotlin) and drive elegant solutions. Contribute to a future-ready and high-quality performance code base, working on technical solutions and product ideas in close cooperation with other developers, data engineers and product managers. Promote agile and software best practices and develop effective solutions to real-world challenges in collaboration with the platform team. Take end-to-end ownership over what you build and focus on qualities such as testing, security, stability, scalability and operability. Foster good agile practices that provide a foundation for iterative product development and build valid solutions to real-world problems. Our Tech Stack We are cloud-native company and leverage AWS cloud and its services (e.g. EKS, EC2, RDS, SQS/SNS, Lambda, S3, etc.). Our APIs are historically built with Spring Boot (Kotlin), but we are looking to become Python-first in our tech stack. Our data pipelines are orchestrated by Dagster (Python) with data stored in S3 and Postgres, and transformations written using dbt. We build frontend applications in Plotly Dash (Python) and web apps in React.js. We deploy our code using CircleCI and Github Actions and use terraform for infrastructure deployment. Our blockchain component is developed with Node.js and integrates third-party services such as IPFS and Ethereum.
