Senior Full Stack Engineer (React / Java) Upto 100K EUR - #2637401

Are you a senior-level expert ready to master a full-stack ecosystem and lead the future of a data-driven CRM platform?

We are partnering with a leading German-headquartered retail innovator as they modernise their proprietary, cloud-native customer relationship management platform. This isn't just an off-the-shelf CRM; it is the heartbeat of the company’s customer interactions, powering high-level insights and driving turnover growth in a major European marketplace.

We are looking for a Senior Full-Stack Developer (frontend-focused) to scale, optimise, and evolve an agile microservices landscape. This is a high-impact role in which you will serve as a technical mentor, architectural visionary, and strategic problem-solver.

Your Mission Impact:

• As a Senior Developer, you will be the driving force behind bringing a complex, data-driven system to its next evolutionary stage.
• You will transition the platform into a future-proof, scalable, and highly personalised future.

Your key responsibilities will include:

• Taking end-to-end responsibility for new, sophisticated features, from initial design to full-stack implementation.
• Playing a key role in defining the technical vision and architecture roadmap, ensuring the full-stack ecosystem is scalable and open to new tech trends.
• Ensuring stable, secure operations of existing services and microservices while continuously optimising performance and security.
• Leveraging real-time data streams via Kafka consumers and pushing boundaries into ML-driven, data-rich personalisation and self-service initiatives.

What You'll Bring:

We need a proactive owner who sees a mess and feels an urge to fix it. The ideal candidate will have:

• Mastery of React AND Java
• Experience with Kafka
• Solid experience designing and implementing microservice architectures, alongside proficiency in both relational (SQL) and non-relational (NoSQL) databases.
• Proven expertise in the development of Kafka consumers for processing real-time data streams.
• Exceptional communication and ownership skills.
• You aren't just a task receiver; you are someone who identifies problems and proposes solutions.
• Experience in Retail, E-commerce, or CRM systems is highly advantageous.

Company Culture:

You will join the Technology and Digital Solutions department, the central hub of the company's innovation. The team is currently at a turning point; following the departure of external consultants, there is a massive opportunity to take the reins and shape the platform’s future.

The culture here values long-term relationships, transparency, and agility. You will work in an environment that rewards independent thought and provides the stability of a market leader while tackling complex technical challenges.

Budget Range: €80,000 - 100,000 EUR (depending on experience).
