Fullstack Software Engineer (m/f/d) – new product!

Fullstack Software Engineer (m/f/d) – new product!

We are CHECK24 —the leading German comparison platform with 20 million customers and over 50 products in comparison.

We are now expanding our team to help build and launch an exciting new financial product —an opportunity to shape something from the ground up and make a real impact from day one.

We are looking for a Fullstack Software Engineer (m/f/d) (Java & React) to join our international, high-impact team at CHECK24 Vergleichsportal Karten & Konten GmbH in Munich. The role offers ownership over architecture and product direction, collaboration in a feedback-driven environment, and the freedom to explore modern tools, including AI-assisted development, to solve meaningful problems.

Responsibilities

• Design and evolve innovative services for our new financial product —helping to build it from scratch and shape its architecture from day one
• Take ownership of the full software lifecycle: design, implementation, deployment, and monitoring
• Build across the stack: from the frontend (React), backend (Spring Boot), to databases (PostgreSQL) and platform components (such as MCP servers)
• Integrate with complex third‑party systems, including banks and communication providers
• Translate business requirements into technical solutions in close collaboration with Product Owners
• Mentor peers through constructive code reviews, establishing best practices, and knowledge sharing

Qualifications

• Degree in Computer Science, Natural Sciences, or equivalent technical field, or comparable practical experience
• Professional experience in software development, ideally in agile environments
• Experience or strong interest in Spring Boot and modern React frontends
• Familiarity with CI/CD pipelines and tools such as Git, Gradle, Jenkins, and Docker
• You are enthusiastic about new technologies, have a hands‑on mentality, and take ownership beyond just committing your code
• Good spoken and written English (min. B2) — German is a plus

Benefits

• Permanent contract and attractive compensation package with annual bonuses for outstanding performance, including vouchers for CHECK24 products and special rates at partner fitness studios
• Personal training budget for conferences, books, and online courses of your choice
• One free meal per day (breakfast or lunch), fresh fruit, and a wide selection of drinks available at any time
• Subsidized Germany Ticket and company bike leasing options for sustainable mobility

We value your commitment: more than 25 years of successes and failures shared across the group in over 15 locations.
