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.

• 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)
