Candidates should view this as a roadmap for their preparation; ensure you are ready for technical assessments early in the process and prepare to dive deep into project-specific architectural details during later stages.

Technical Depth

We look for engineers who understand the underlying mechanics of their tools. Whether it is dependency injection or memory management, we want to see that you understand the "under the hood" operations of your framework.

Be ready to go over:

• Framework internals and bean lifecycles.
• Design patterns versus implementation scopes.

As a Software Engineer, you will be responsible for the full lifecycle of software development, from requirements gathering to deployment and maintenance. You will work closely with product managers to define feature sets that enhance our trading capabilities, and with compliance teams to ensure that every update meets the stringent regulatory requirements of the financial industry.

You will often find yourself collaborating across departments to bridge the gap between technical infrastructure and user-facing features. Expect to participate in code reviews, contribute to architectural discussions, and take ownership of critical services that support our real-time trading platform.

A successful candidate possesses a strong foundation in backend development and a proactive approach to engineering. While specific requirements vary by team, the following are essential:

• Must-have skills: Deep proficiency in Java and Spring framework, experience with distributed systems, and a strong understanding of database management.
• Nice-to-have skills: Experience with cloud-native technologies, familiarity with high-frequency trading systems, and knowledge of European financial regulations.
• Soft skills: Clear communication, a collaborative mindset, and the ability to explain complex technical concepts to non-technical stakeholders.

Q: How long does the hiring process usually take? The timeline varies, but we aim for an efficient process. Most candidates move through the stages within a few weeks, depending on availability and scheduling.

Q: What is the best way to prepare for the technical interview? Focus on your past projects. Be prepared to explain the architecture of systems you have built and the technical trade-offs you made.

Q: Is the team culture collaborative? Yes, we emphasize a culture of open communication and peer review. We look for engineers who are eager to share knowledge and contribute to a team-first environment.

Q: What differentiates successful candidates? Successful candidates are those who demonstrate deep technical ownership and a genuine interest in the specific challenges of the financial brokerage industry.

• Be prepared to deep-dive: If you mention a specific technology or architecture on your resume, be ready to explain how it works at a granular level.
• Focus on the "Why": When answering questions about your previous projects, focus on the rationale behind your technical decisions.
• Engage with the interviewer: Treat the interview as a technical discussion rather than a one-way interrogation; ask thoughtful questions about our infrastructure.
• Review your basics: Ensure you are comfortable with core framework concepts, as these often serve as the foundation for more complex technical discussions.

The role of a Software Engineer at FlatexDEGIRO SE is both challenging and rewarding, offering the opportunity to build systems that define the future of retail trading.
