Drive payment platform modernisation

Company Description
Showtime Consulting is a leading provider of Shielded Cloud and Digital Solutions across Australia and New Zealand. We specialise in delivering secure, enterprise-scale technology solutions across cloud, data, AI, DevSecOps, platform engineering, and digital transformation programs.

We partner with major organisations to build high-performing technology teams and deliver innovative technology platforms that improve productivity, operational efficiency, governance, security, and business outcomes.

As part of our continued growth across the financial services sector, we are seeking experienced payments technology professionals to support critical payment processing platforms and modernisation initiatives within large enterprise environments.

The Role
We are seeking an experienced Connex Developer / Support Specialist to join a high-performing payments technology team.

This role is focused on the development, enhancement, support, and ongoing maintenance of the Connex Payment Switch running on IBM Mainframe (z/OS). You will play a key role in ensuring the stability, reliability, and performance of business-critical payment processing systems while supporting regulatory, compliance, and modernisation initiatives.

The ideal candidate will bring strong Connex and Mainframe expertise, a solid understanding of payment processing environments, and the ability to collaborate effectively with architects, designers, vendors, and delivery teams.

Key Responsibilities

Provide build, enhancement, and production support for the Connex Payment Switch on IBM Mainframe (z/OS).
Review, assess, and provide recommendations on vendor-proposed Connex changes and customisations.
Collaborate closely with Solution Designers, Architects, and delivery teams to support business and technical initiatives.
Enhance and maintain Host Scheme Payment Interfaces (PIs) during regulatory and compliance releases.
Support migration and modernisation initiatives, including Connex integration with new payment switch platforms.
Monitor the health, performance, and stability of the Connex Mainframe environment.
Apply vendor-supplied Connex maintenance updates, including configuration and code changes.
Implement additions, modifications, and deletions of Payment Interfaces (PIs), Transaction Handlers (THs), and associated batch processes.
Investigate, troubleshoot, and develop fixes for Connex-related production incidents and defects.
Participate in system testing, release management, and deployment activities to ensure high-quality delivery.

What You'll Need

Bachelor's degree in Computer Science, Information Technology, Engineering, or a related discipline.
Strong understanding of Payment Switch functionality and payment processing environments.
2 to 20 years of experience in Connex support, development, or a similar payments technology role.
Proven expertise in gathering, documenting, and analysing functional and technical requirements.
Strong problem-solving, troubleshooting, and analytical skills.
Ability to work in dynamic environments and adapt to evolving technologies and project requirements.
Self-motivated, proactive, and capable of working independently as well as within a team.
Detail-oriented, with a strong focus on testing, quality assurance, and production stability.
Excellent collaboration and stakeholder management skills.

Technical Skills

Extensive experience with Connex configuration and support on IBM z/OS.
Strong knowledge of:
- IBM z/OS
- COBOL
- Assembler
- Db2
- IBM JCL
- Finsim / Paysim
- Payment Switch and transaction processing systems
Exposure to modern technologies and integration frameworks, including:
- Java
- Spring Boot
- REST APIs
- GitHub
- AWS
- Splunk
- Kafka

Why Join Us?

Work on business-critical payment platforms supporting large-scale transaction processing environments.
Contribute to strategic payment modernisation and platform transformation initiatives.
Collaborate with experienced architects, engineers, and payments specialists.
Gain exposure to both traditional Mainframe technologies and modern integration platforms.
Join a high-performing team delivering innovative financial services technology solutions.
Be part of a growing consultancy delivering complex technology outcomes across Australia and New Zealand.
