Help organisations modernise critical business systems
At TXP, we're specialists in solving complex technology challenges. As demand for legacy modernisation continues to grow, we're expanding our team and are looking for an experienced Legacy Conversion Consultant to support major application transformation programmes across both public and private sector clients.
This is a unique opportunity to combine deep technical expertise with innovative automation technology, helping organisations move away from legacy platforms and embrace modern architectures.
You'll work with TXP's proprietary migration tooling to analyse, convert and validate enterprise applications, while helping shape the future of our conversion methodologies and automation capabilities.

- Supporting the migration of applications to:
- Native COBOL environments (CICS, IMS-DC and DB2)
- Modern platforms including Java, Spring Boot, .NET, Angular and cloud technologies
- Defining migration approaches for databases, online transactions, batch processing and user interfaces.
- Validating converted applications to ensure quality, performance and functional equivalence.
- Collaborating with architects and technical teams to develop migration strategies and delivery roadmaps.
- Supporting proposals, Statements of Work and technical solution design activities.
- Contributing to the continuous improvement of TXP's migration tooling and delivery methodologies.
What we're looking for
We're interested in hearing from technology professionals who have experience in application modernisation, migration, conversion or platform transformation projects.
You'll bring experience in some of the following:
- COBOL, CICS, IMS-DC and DB2 environments
- Mainframe technologies and tooling including ISPF, SCLM, SPUFI and JCL
- Java, Spring Boot, .NET, Angular or cloud-native technologies
