Tech Lead/Sr. Cobol Developer

This is a full‑time consulting assignment starting as soon as possible, with an initial term of 6 months and a strong likelihood of extension.

 (LOCATION: Gdynia/Gdańsk/Sopot)

Assignment description

You will be the lead mainframe developer for a new team working on high‑volume, business‑critical payment products (e.g. Swish in Sweden and similar services in Norway).

You will:

- Take technical ownership of mainframe development within your area

- Work hands‑on with COBOL to design, implement, and maintain new functionality (not only legacy maintenance)

- Translate business requirements into robust, scalable mainframe solutions

- Drive tasks from definition to delivery with minimal supervision

- Collaborate closely with sister teams in Sweden and Poland 

About the team

You will be the first hire in a newly created team, which will be built around you as the technical lead.

The team will:

- Work closely with existing “sister” mainframe and payments teams that currently handle this domain

- Collaborate with a dedicated mainframe‑experienced project manager/scrum master and separate QA/testing teams

- Operate in an agile way (bank’s own variant of Scrum suited to mainframe work)

- The engineering organization is large and mature, with many mainframe and payments engineers already in place; this is a strategic expansion of that capability.

Must haves

- 7+ years of hands‑on mainframe development, with strong COBOL expertise

- Proven experience delivering in IBM z/OS environments

- Ability to lead technically: set direction, make architectural and design suggestions, and mentor others

- Strong, proactive consulting mindset: you seek information, talk to stakeholders, and drive work forward instead of waiting for instructions

- Very good communication skills in English (spoken and written)

- Ability and willingness to work on‑site in the Gdynia/Gdańsk area at least 3 days per week

- EU citizenship (required due to internal security and data‑protection standards at the bank)

Other requirements

- Comfortable working in a large enterprise/banking environment

- Able to work standard “Swedish office hours” (approximately 08:00–17:00 CET) with some flexibility

- Open to iterative/agile ways of working alongside teams that still have some waterfall‑like elements, as is common in mainframe contexts

- Strong sense of ownership and quality; you can work independently but also know when to involve others
