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)
