General description: Good experience in designing robust APIs using OpenApi and having strong sense of serverless architecture to help deliver next generation cloud native system.

Requirements: Key/primary skills: Java, Python, Spring Boot and other Frameworks, Cloud Platforms (inc. AWS), JUnit5, Lambda, Containers Secondary skills: Mockito, Agile, No SQL Databases

• Create a template service that talks to database (MongoDd) – note: we already have templates for FE, JCS, FCS, lambdas and TMF Entity.

• Make the code production ready for a sample FE, JCS, FCS, lambdas and TMF Entity. Production readiness means:

o Security vulnerabilities fixed

o Observability, troubleshooting set up

o Data logging compliance followed

o Tests automated (as much as possible)

o Start on PaCE/performance tests

• Mentor current devs to understand the above NFRs and grow in their roles

In partnership with one of the global consulting enterprises, on a large-scale digital program for a UK Telecommunication industry client, we are seeking talented iOS Software Engineer to join the World Service App team. These roles focus on delivering high-quality, accessible, and scalable native mobile applications used by millions of users worldwide.

As part of the World Service App team, you will work on building and evolving a global-scale mobile application that delivers a seamless user experience across platforms. The focus is on modern native development practices, leveraging SwiftUI and TCA on iOS. You’ll collaborate closely with designers, testers, and product managers to ensure consistent design system implementation, strong accessibility standards, and smooth integration with backend services.

Key Responsibilities
