Senior+/Lead Backend Engineer (Data / Algorithms)

About the Project:

• Our UK-based customer is building a new multi-tenant platform for asset management – a complex, interconnected system designed to unify disparate data sources and ontologies into a single, collaborative environment.
• The platform requires advanced interoperability between different domains, offline-first functionality with data synchronization, and scalable architecture to support multiple clients and access levels.
• This is a long-term project (6–12 months minimum), where you will have the opportunity to shape architecture, solve challenging data problems, and work alongside a highly collaborative team in an agile environment.
   

Responsibilities:

• Design and develop core system components, including:

multi-tenant data management and synchronization,

interoperability across heterogeneous systems,

rule evaluation and advanced data processing.

• Contribute to architectural decisions and implementation of shared libraries.
• Implement offline-first capabilities and data sync mechanisms.
• Collaborate with product owners, architects, and other developers in an agile setup (daily standups, task boards, CI/CD).
• Ensure scalability, reliability, and maintainability of the system.
• Stay adaptable and contribute across the stack as needed.
