Lead, Digital & Wholesale Banking at Interswitch

• To deliver hands-on technical engineering of the Temenos T24 / Transact core banking platform — building, customizing, integrating and tuning the system so that digital and wholesale banking products are delivered to specification, on time and to production-grade quality.
• This is a senior individual contributor technical role reporting to the Head, Digital & Wholesale Banking.
• Where the Head owns architecture, governance and stakeholder strategy, the Senior Technical Consultant is the senior pair of hands that turns those designs into working, tested, secure code and configuration.
• Without this role, technical designs and product requirements would not be reliably engineered into the platform.

Responsibilities 

Technical Delivery & Customization:

• Local Development: Build and maintain local developments — Versions, Enquiries, Templates, routines and APIs — using InfoBasic, jBASE and the Temenos Integration Framework (IF), in line with the architecture set by the Head.
• Implementation Support: Execute the technical build for T24 implementations, upgrades and module rollouts from development through to post-go-live support.
• Standards Adherence: Apply coding, version-control and local-development standards so that work is consistent, reviewable and maintainable.

Module Configuration & Integration:

• Module Configuration: Configure and fine-tune core modules supporting corporate lending, trade finance, treasury and digital channels (LD, FT, MD, LC, TR, AC).
• Integration Engineering: Engineer secure, real-time interfaces between the T24 core and peripheral systems (payment gateways, CRM and mobile/digital banking apps) using IF and IRIS / APIs.

Quality Assurance & Performance Tuning: 

• Testing: Develop and execute Unit, System Integration (SIT) and User Acceptance Testing (UAT) cases for customizations and integrations and remediate defects.
• Troubleshooting: Perform root-cause analysis on system errors, performance bottlenecks and database locks, and implement durable fixes.
• Performance Tuning: Profile and tune jBASE / TAFJ / TAFC performance to meet availability and response-time targets.

Environment & Release Support: 

• Environment Management: Support multi-environment landscapes (Dev, Test, UAT, Production), including code promotion, data migration and environment integrity.
• Release & Recovery: Support deployment, release and disaster-recovery activities, contributing to high-availability and business-continuity assurance.

Documentation & Knowledge Sharing: 

• Technical Documentation: Produce technical specifications, build notes and user guides for delivered customisations and integrations.
• Knowledge Sharing: Mentor junior developers and analysts and contribute to the team’s shared technical knowledge base.

Position in Structure: 

• The role reports to the Head, Digital & Wholesale Banking and operates as a senior technical contributor across the following capability areas of the Temenos estate:
  • Customisation & Local Development: InfoBasic / jBASE development of Versions, Enquiries, Templates, routines and APIs to the governed architecture.
  • Module Configuration: Configuration and optimisation of wholesale, corporate and digital modules — lending, trade finance, treasury and digital channels.
  • Integration Engineering: Real-time interfaces between the T24 core and peripheral systems via Integration Framework and IRIS / APIs.
  • QA, Performance & Environments: Unit / SIT / UAT test build and execution, performance tuning, environment support and release / DR assistance.

Behavioral Competencies: 

• Analytical Thinking
• Strong problem-solving with the resilience to resolve critical, high-pressure system issues.
• Drives Results Delivers quality customisations and fixes to time across multiple concurrent priorities.
• Ensures Accountability Takes ownership of code quality, test coverage and the stability of delivered work.
• Communicates Effectively Clear written and verbal communication with both technical peers and business analysts.
• Optimises Work Processes Continuously improves build, test and deployment practices for reliability and speed.

Skills: 
Temenos Technical Mastery: 

• Strong working knowledge of Temenos T24 / Transact architecture, TAFJ / TAFC runtimes and the jBASE database environment.

Development Tools:

• Hands-on proficiency in InfoBasic programming, Design Studio, Integration Framework (IF) and the Interaction Framework (IRIS / APIs).

Functional Breadth:

• Practical configuration of wholesale and corporate modules (LD, FT, MD, LC, TR, AC) and digital banking interfaces.

Environment & Migration: 

• Experience working across Dev / Test / UAT / Production landscapes and executing data migration protocols.

Testing & Tuning: 

• Competence in Unit / SIT / UAT design and in performance profiling and tuning.

Requirements

Education: 

• General Education Bachelor’s or Master’s Degree in Computer Science, Information Technology, Software Engineering or a related discipline. 
• Relevant certifications is expected, such as:
  • Certified Temenos T24 / Transact Consultant — Technical (highly desirable)
  • Temenos Integration Framework / Design Studio certification — advantageous
  • InfoBasic / core-banking development certification — advantageous Experience. General

Experience:

• Minimum of 6–8 years’ experience in core banking systems, with at least 3–4 years of hands-on Temenos T24 / Transact technical development, customization and integration.

Managerial Experience: 

• No direct management responsibility; expected to provide technical guidance and mentoring to junior developers and analysts and to lead discrete technical workstreams.

KPI Framework: 

• Performance is measured across five dimensions spanning build quality, delivery and platform stability:
• Build Quality: Defects escaping to production; code-review and standards-compliance pass rate; rework rate on customisations.
• Delivery Execution: Assigned customisations, configurations and integrations delivered to plan; on-time, on-spec completion.
• Quality Assurance: Unit / SIT / UAT pass rate; test coverage of delivered components; defect remediation turnaround.
• Platform Stability & Performance: Incident rate attributable to own work; performance/tuning improvements achieved; database-lock recurrence.
• Environment & Documentation: Successful code promotion and migrations; DR-test contribution; completeness of technical documentation.

Reporting line: 

• The Lead, Digital & Wholesale Banking (Temenos Transact) reports to the Head, Digital & Wholesale Banking (Temenos Transact Consultant).
