ERP Developer

We're looking for a motivated, technically capable Mid-Level Developer to join our Air Enterprise Resource Planning (ERP) team within an aerospace & defence environment. This is a varied, general-purpose development role covering the full development lifecycle - building and supporting solutions in Infor LN, helping with integrations, and maintaining/enhancing existing functionality. While Infor LN is the core platform today, we value strong programming fundamentals, curiosity, and a willingness to learn as the tooling may evolve over time.

What you'll do (core responsibilities)

• Design, develop and maintain customisations, extensions and workflows within Infor LN using BaanC (Baan 4GL/Tools)
• Support and improve existing LN sessions, reports, and business objects across modules such as Manufacturing, Finance, Warehousing, and Order Management
• Analyse business requirements and translate them into practical technical solutions
• Assist with system integrations (e.g., Infor ION, BODs, and third-party data exchange where required)
• Take part in testing, debugging, and code reviews to maintain stability and quality
• Produce clear documentation (e.g., technical notes, functional specs, change records)
• Work closely with functional consultants, business analysts, and end users to deliver robust outcomes
• Contribute to upgrades, patches, and release planning when needed
• Follow company Safety, Health & Environment (SHE) expectations and report hazards/incidents appropriately

What we're looking for (essentials)

• Strong structured programming fundamentals (experience with C or similar is a strong advantage due to BaanC syntax)
• Familiarity with ERP concepts and at least 1-2 ERP module areas (e.g., manufacturing, finance, procurement, warehousing)
• Good analytical/problem-solving skills and attention to detail
• Clear communication skills (able to explain technical topics to non-technical stakeholders)
• Comfortable working in an environment with competing priorities and changing requirements

Nice to have

• Hands-on development in BaanC and the LN Tools development environment
• Experience with LN data structures/queries and reporting tools (BI / SSA reporting)
• Background in manufacturing, aerospace, defence, industrial, or other regulated/audited IT environments
• Exposure to Infor platforms beyond LN (e.g., SyteLine / CloudSuite Industrial) and structured change management

Working pattern / security

• 3 days per week on-site
• Roles are subject to security/export control restrictions
• BPSS minimum required; some roles require higher vetting (often 5-10 years UK residency depending on level)
