About the role..

A techno-functional consultant is required to support and evolve a major bank lending platform built on FIS ALS, currently undergoing mainframe modernisation.

The role sits with the ALS development team. You will turn business need into specifications a mainframe developer can build from, and tests that prove the change behaved as specified. The work is inside the system: tracing why an account behaved as it did, identifying the parameter driving it, verifying overnight cycle output, and reconciling what ALS sends downstream against what arrives.

This is a hands‑on technical role, not a coordination role.

Requirements

Essential skills

• Hands‑on FIS ALS experience. This is a hard requirement and cannot be substituted by general lending experience.
  
• 8+ years' experience, the majority in mortgage or consumer lending - loan servicing, escrow, default management and collections.
  
• Working knowledge of the mainframe stack underpinning ALS: COBOL, JCL, DB2, CICS.
  
• Specification craft: Business Requirement Documents, Functional Requirement Documents, functional and technical specifications, acceptance criteria, current- and future-state process mapping.
  
• Requirements elicitation through workshops and stakeholder interviews.
  
• Ability to specify interfaces, batch processing, file‑based feeds and data mapping between ALS, core banking and treasury systems.
  
• SQL and RDBMS concepts, sufficient to validate your own analysis.
  
• Experience delivering regulatory and compliance‑driven lending change.
  
• Experience across tiered environments: Dev, Test, UAT, Pre‑Production, Production and DR.
  
• Prior work on ALS upgrades, patches or FIS vendor releases.
  
• Experience on a mainframe modernisation or platform migration programme.
