Backend Tech Lead (Java/PHP)

🚀 AIMPROSOFT is looking for a Backend Tech Lead (Java/PHP)!

Aimprosoft is looking for an experienced Backend Tech Lead (Java/PHP) to join a telecom transformation project on a full-time contract basis (6–12 months).

You’ll take technical ownership across two connected development streams — modernization of an existing broadband platform and development of a new customer-facing portal.

🎯 About the project & role

The client is an established UK telecom service provider undergoing a major platform transformation.

The project combines two parallel streams. The first focuses on stabilizing and modernizing an existing PHP-based broadband platform hosted in AWS, restoring critical telecom capabilities and integrations. The second involves building a new customer-facing portal with a Java backend and React frontend.

As a Tech Lead, you’ll lead technical discovery, define the target architecture and ensure architectural alignment between the legacy and new platforms. This is a hands-on leadership role combining solution design, technical leadership, and work with critical parts of the codebase.

Your responsibilities will include:

Leading technical discovery and defining the target architecture and modernization strategy

Analyzing and modernizing the existing PHP platform, AWS dependencies, and integrations

Driving the architecture of the new Java backend and its integration with the React-based portal

Designing APIs and integration contracts between legacy, new, and external systems

Leading technical implementation across both modernization and new development streams

Establishing technical standards and reviewing critical designs and code changes

Mentoring engineers and collaborating closely with client and project stakeholders
