Job Description

We're looking for a talented Senior Software Engineer with strong Kotlin skills (or Java and willing to learn Kotlin) to join us in Berlin or Munich.  

In the Foundation Division of FlixTech, our Finance Technology Stream helps the business grow efficiently by delivering smart, compliant, and automated finance solutions. We keep things simple for our internal users so they can spend less time on manual tasks and more time on what matters. The team you will join is not focused on user-facing experiences or polished UIs. Our success is measured by data correctness, consistency, and trustworthiness, even in complex and evolving business scenarios. You'll be part of a self-managed, cross-functional team with a Product Owner and fellow Software Engineers, directly supporting new country launches, new business models, and the continuous evolution of Flix's financial backbone. 

This role is well-suited for someone who enjoys ownership, working close to real business problems, and contributing to the long-term foundations of an international company. If you value collaboration, thoughtful engineering, and building systems that need to be right, not just fast, we'd love to meet you. 

About the Role

• Design, develop, and maintain backend services using Kotlin 
• Build and evolve scalable, event-driven systems that process, validate, and expose financial data 
• Use AI tools such as Claude Code and Copilot conscientiously to assist in faster and higher-quality development
• Collaborate closely with the Product Owner and Finance stakeholders to translate business requirements into robust technical solutions 
• Ensure data accuracy, traceability, and auditability across financial and accounting flows 
• Improve system reliability, observability, and performance for business-critical processes 
• Contribute to clean code, architectural discussions, and continuous improvement of engineering practices 

About You

• 5-7 years of experience developing backend systems, with Java or preferably using Kotlin
• Hands-on experience building backend services using the Spring ecosystem (e.g. Spring Boot, Spring Data) 
• Experience with event-driven design (e.g. asynchronous processing, messaging, domain events) 
• Practical experience with cloud platforms (preferably AWS, or similar) 
• Solid understanding of databases, both NoSQL (e.g. DynamoDB) and/or relational systems 
• Comfortable working in complex, data-heavy domains (ideally Finance), where investigation, analysis, and precision are key 
• Communicate clearly in English, open-minded, curious, and motivated to continuously improve both yourself and the systems you work on 

We recognize that everyone carries a unique set of valuable skills and experiences. If you think you could have an impact even though you don't meet 100% of the requirements, we still encourage you to apply. We want to hear from you!  

What We Offer

• Travel perks: 12 free Flix vouchers + 12 discount vouchers for friends & family. 
• Work from (M)Anywhere: Depending on your role, work from another location for up to 60 days per year. 
• Hybrid work model: We are an office-first company, but we offer flexibility to balance work and life. 
• Wellbeing support: Access confidential 1:1 counselling, courses, and stress management for yourself and up to four family members. 
• Learning & Development: Take advantage of language classes, training courses, and expert-led sessions to grow your skills. 
• Mentoring Program: Connect with experienced colleagues to gain insights and accelerate your career.

Expert Career Tips for Senior Software Engineer (Kotlin,Java) (m/f/d) Roles

To succeed in a competitive market as a Senior Software Engineer (Kotlin,Java) (m/f/d), you need more than just technical skills. Here are some expert strategies to elevate your profile:

• Build a Strong Portfolio: For technical roles, a clean GitHub or a personal project site is essential. For non-technical roles, a case study portfolio demonstrating problem-solving and impact is equally valuable. Show, don't just tell, what you have achieved in your previous positions.
• Master the Narrative: When interviewing, use the STAR method (Situation, Task, Action, Result) to structure your answers. Quantify your results wherever possible—mentioning "increased efficiency by 20%" is much more impactful than saying "improved efficiency."
• Continuous Learning: The industry moves fast. Whether it's staying updated with the latest AI tools or mastering a new management methodology, continuous professional development is key. Consider obtaining industry-recognized certifications that align with Senior Software Engineer (Kotlin,Java) (m/f/d) requirements.
• Networking: Connect with other professionals in similar roles. Join online communities, attend webinars, and engage in meaningful discussions on professional social networks. Often, the best opportunities come through referrals and community engagement.
• Soft Skills Matter: Communication, empathy, and leadership are often the deciding factors between two equally qualified technical candidates. Cultivate these skills as they are universally valued across all industries and seniority levels.

Additionally, research the specific company's culture and values. Tailoring your application to show how you align with their mission can significantly increase your chances of moving forward in the process.

Salary & Compensation

Salary not disclosed; typically competitive for the role.

Work Arrangement

Type: On-Site

Standard business hours at the office.

Comprehensive Application Strategy & Hiring Process

Applying for a new role is a marathon, not a sprint. Follow this strategic approach to maximize your success rate:

1. Initial Research & Tailoring

Don't send the same resume to every employer. Spend at least 30 minutes researching the company. Look for recent news, their product roadmap, and their team structure. Modify your summary and core competencies to reflect the specific keywords found in the job description.

2. The Perfect Cover Letter

If the application allows for a cover letter, use it to tell a story that your resume cannot. Explain why you are passionate about this specific company and how your unique background makes you the perfect fit for the challenges they are currently facing.

3. Navigating the Multi-Stage Interview

Most modern hiring processes involve 3-5 stages. This typically includes a recruiter screen, a technical or skill-based assessment, a peer interview, and a final leadership round. Prepare for each stage differently: focus on enthusiasm and fit for the recruiter, technical depth for the assessment, and strategic vision for the leadership round.

4. Post-Interview Follow-Up

Always send a personalized thank-you note within 24 hours of each interview. Reference a specific topic discussed during the call to demonstrate your active listening and genuine interest in the role.

By following these steps, you demonstrate a high level of professionalism and attention to detail that sets you apart from the average applicant.

Typical Interview Process

1. Resume screening
2. HR call
3. Skill interview
4. Final manager interview
5. Offer

Tip: Research the company's products and culture.

Global Market Intelligence & Relocation Insights

At JobSetuu, we specialize in helping talent navigate the global job market. Here is what you need to know about the current landscape in Munich, Bavaria, Germany and beyond:

The demand for skilled professionals is increasingly borderless. For roles based in Munich, Bavaria, Germany, understanding the local cost of living, visa requirements (if applicable), and cultural nuances is vital. If this is a remote role, consider the time zone alignment and the asynchronous communication culture of the hiring organization.

Relocation Support: Many forward-thinking companies offer relocation packages that include moving stipends, temporary housing, and legal assistance with work permits. When evaluating an offer, look beyond the base salary—consider the total compensation package, including equity, bonuses, and healthcare benefits.

Work-Life Balance Trends: Hybrid and remote work have become standard in many regions. Research the local labor laws and common practices regarding work hours and vacation time to ensure the role aligns with your lifestyle goals.

Leveraging JobSetuu's tools can help you compare salaries across different cities and understand the "purchasing power" of your potential offer, ensuring you make an informed decision for your long-term career path.

Skills & Competency Roadmap for Professional Development

To remain competitive in Professional Development, we recommend focusing on the following core competencies over the next 12-18 months:

• Technical Mastery: Deepen your expertise in the core tools and languages relevant to your field. For developers, this might be cloud architecture; for marketers, it might be data-driven attribution modeling.
• AI Augmentation: Learn how to leverage generative AI and automation tools to increase your productivity. Understanding how to integrate these technologies into your workflow is becoming a non-negotiable skill.
• Leadership & Strategy: Even in individual contributor roles, the ability to think strategically and lead projects from inception to completion is highly valued. Focus on stakeholder management and high-level project planning.
• Data Literacy: The ability to interpret data and use it to drive decisions is essential across all business functions. Familiarize yourself with data visualization and basic analytical concepts.
