Desk workflow Engineer- VBA required

Responsibilities

• Work directly with front-office and operations users to scope enhancement requests, reproduce defects, and deliver controlled, behaviour-preserving changes to live business workflows.
• Analyse legacy VBA logic, workbook formulas, templates, and embedded business rules to extract and document the operational rules driving confirmation, basket, and email outputs.
• Contribute to the migration of selected spreadsheet workflows onto the desk's desktop application replacement for the macro as those workflows are prioritised for modernisation.
• Develop and maintain Rust application code, including domain libraries, persistence, runtime services, and user-facing functionality.
• Hold Rust code to the team's engineering standards: fully typed, strictly memory-safe, no panics, unsafe forbidden, with typed errors and explicit domain models.
• Work with hybrid local/cloud datastores for persistence, query, and lineage use cases.
• Document assumptions, reconcile generated outputs, and support auditability across legacy macros, regulatory XML artefacts, and modern application state.
• Collaborate with traders, operations, compliance, and technology stakeholders to translate operational requirements into controlled deliverables.
• Experience / Competences
• Essential
• Solid Excel/VBA development experience, including maintaining production macros, enhancing template-driven outputs, and supporting business users who depend on Excel-based tooling.
• Practical experience modifying legacy macro estates safely; recognising embedded business rules, workbook coupling, Named Ranges, and the operational consequences of behavioural change.
• Reasonable experience with C# and Windows Forms, including maintaining and enhancing production desktop applications that integrate with trader workflows, and supporting the users who depend on them.
• Track record working directly with non-technical business users in time-sensitive operational environments, including scoping changes, documenting assumptions, and explaining trade-offs in plain language.
• Desired
• Strong data-modelling instincts; the ability to identify real domain concepts and model them explicitly rather than relying on strings, generic JSON, loosely typed maps, or spreadsheet conventions.
• Solid Rust development experience covering ownership, typed error handling, async-aware code, and safe refactoring in larger codebases, comfortable working to strict standards (fully typed, strictly memory-safe, no panics, unsafe forbidden).
• Experience with TypeScript and functional programming patterns in TypeScript.
• Experience using agentic coding tools, including context engineering through instruction files and memory, scoped tool permissions and hooks, subagent delegation, and verification guardrails.
• Experience with confirmation workflows, basket management, email automation, trade lifecycle events, or other equities front-office /

The macro estate covers confirmation generation, confirmation template management, basket management, email generation, and other desk-facing workflow automation. The developer works directly with the business to scope enhancement requests (most commonly confirmation template enhancements and other functionality enhancements), reproduce defects, and deliver controlled changes to live operational tooling without disrupting day-to-day trading and post-trade workflows.

The active Rust scope supports operations users in producing automated HKTR ISO 20022 XML files for the Hong Kong Trade Repository.
