We are seeking an experienced Software Engineer to support the migration of a legacy on-premise application into a modern, cloud-based environment on AWS. This role is ideal for an engineer with strong Delphi expertise who can work across legacy components while supporting modernisation into languages such as C# or .NET where required.

You will work as part of a collaborative, delivery-focused team, contributing to application refactoring, rebuilding Delphi dependencies, and helping transition legacy tech into a sustainable future-state architecture.


Project Overview

The project involves migrating a legacy PHP and Delphi application running on Windows / MS SQL to an AWS-hosted environment using PostgreSQL.
Key elements include:

  • Re-platforming the existing application from on-premise Windows servers to AWS.

  • Converting the MS SQL database to PostgreSQL.

  • Removing Windows components and transitioning to Linux-based deployments.

  • Reviewing Delphi dependencies and re-writing/re-architecting components where necessary in a modern language (C# or .NET).

  • Supporting any small remaining elements of Delphi UI work.


Key Skills Required

Delphi (essential)
✔ Experience with Lazarus (open-source Delphi IDE) - highly beneficial
✔ Knowledge of WebSockets and REST APIs in Delphi
✔ Strong communication skills and a collaborative mindset
✔ Ability to assess and re-engineer legacy codebases
✔ Familiarity with PHP considered helpful (but not required)


Nice to Have

  • AWS

  • Docker

  • Experience migrating or modernising legacy windows-based applications

  • Exposure to C# / .NET development
