About The Role

We are looking for a skilled back-end developer with a strong foundation in either C# (.NET Core) or Node.js, and proven experience working with Azure cloud services, to join our growing team at Jacobs. The ideal candidate will bring technical depth in back-end development, a pragmatic approach to problem solving, and the ability to collaborate effectively within a multidisciplinary team. You will be responsible for designing, developing, and maintaining reliable and scalable web application services that meet the needs of both internal stakeholders and end users. Strong communication skills and the ability to translate technical decisions into business value are essential.

Responsibilities

• Integrate backend services with Azure cloud infrastructure, leveraging key services such as App Services, Key Vault, and Blob Storage.
• Design and manage relational databases (e.g., MS SQL, PostgreSQL, MySQL) and non-relational databases (e.g. NoSQL, MongoDB) to support application logic, data transformation, and efficient storage.
• Collaborate with front-end developers by providing mock APIs and data models to streamline parallel development and decouple frontend/backend workflows.
• Partner with Product Owners, Digital Delivery Leads, and other developers to evolve backend architecture and continuously enhance system performance and resilience.
• Contribute to global product initiatives by building libraries, APIs, and shared services in line with business and technical requirements.
• Produce clear, maintainable documentation for backend systems, interfaces, and deployment pipelines
