Are you a seasoned PL/1 professional looking for one final challenge where your expertise will truly make a difference?
We are seeking an experienced PL/1 Developer to play a pivotal role in the modernisation of a business-critical legacy application. This is a unique opportunity to apply years of hard-earned knowledge to reverse engineer and analyse a complex system, uncovering how its functions, procedures, modules, interfaces, and program calls work together to support essential business operations.
Your expertise will be instrumental in guiding the migration of the underlying database from Datacom (Broadcom) to VSAM, helping ensure valuable business functionality is preserved, understood, and thoroughly tested throughout the transition.
This role is ideal for someone who enjoys solving complex technical challenges, documenting and sharing knowledge, and leaving a lasting impact on a significant transformation programme. Whether you're currently consulting, semi-retired, or simply looking for a role where your specialist skills are genuinely valued, we'd love to hear from you.
We can offer flexibility to suit your lifestyle, including part-time arrangements, and the role can be based in Wellington, Auckland, or Christchurch. The focus is on finding the right person with the right experience, not fitting them into a rigid working model.

- Analyse and reverse engineer PL/1 applications to understand and document how they work.
