Tech Talent Programme - Junior Application Engineer

Start your IT engineering career at the heart of global financial markets

Do you enjoy problem‑solving and want to start a career in IT where your work really matters? Are you curious about how technology supports the stability, safety and efficiency of financial markets worldwide?

Euroclear is a leading global provider of post‑trade services for the financial industry. Headquartered in Brussels and operating in more than 15 countries, we ensure the settlement, custody and servicing of securities transactions across borders and asset classes. In simple terms, we are a bank for banks, operating at the very core of the global financial system.

Technology is central to this mission. Our IT platforms support business‑essential, time‑critical processes and must deliver reliability, security and performance every single day. This is why Euroclear continues to invest heavily in engineering excellence, modernisation and the development of early‑career talent.

You will join Group Business Solutions (GBS), the division responsible for delivering and running Euroclear’s core IT solutions. GBS teams build, enhance and support applications used daily by financial institutions worldwide, deploying change in a controlled way while ensuring production stability in complex, high‑reliability environments.

The role is based in Kraków
, a growing and diverse tech hub within Euroclear. The Kraków site offers a welcoming environment for early‑career professionals, with strong local support, opportunities to connect across teams, and a culture that values learning, curiosity and collaboration.

To support graduates and early‑career talent, Euroclear created the Tech Newbies Programme in Kraków. This is a structured onboarding journey combining training, mentoring and hands‑on experience within real IT teams.

No prior professional IT experience is required. The programme is designed to help you build solid engineering foundations while discovering how large‑scale, mission‑critical systems operate in practice.

As an Junior Application Engineer (Mainframe), you will take your first steps as an engineer working on business‑essential applications that support global financial markets.

You will be trained in enterprise mainframe technologies and progressively grow in autonomy and responsibility, contributing to the development, maintenance and support of production‑grade systems. The role is designed as a structured entry point into IT engineering
, with a clear development path toward the Engineer role in line with the Euroclear Engineering Career Ladder.

In addition to technical skills, you will gain exposure to delivery processes, operational constraints and business flows within GBS. Over time, this experience can also open opportunities to move toward other roles such as Test Analyst, Business Analyst or delivery coordination roles, depending on your interests, strengths and organisational needs.

Mainframe technology is rarely taught at university, yet it remains the backbone of many of the world’s most critical financial systems.

At Euroclear, mainframes:

• support high-volume, time‑critical business operations,
• run applications requiring exceptional reliability, performance and security,
• process large volumes of data with predictable, industrial‑grade robustness.

The skills you develop — engineering discipline, system thinking and a reliability mindset — are highly transferable and remain valuable throughout your IT career, including beyond mainframe environments.

You will start in a guided environment and progressively grow in responsibility and independence.
