Platform Engineer - Java Developer & Elastic Search

We help the world run better
At SAP, we keep it simple: you bring your best to us, and we'll bring out the best in you. We're builders touching over 20 industries and 80% of global commerce, and we need your unique talents to help shape what's next. The work is challenging – but it matters.

Constant learning, skill growth, great benefits, and a team that wants you to grow and succeed. 

What you'll do

We’re looking for Software Engineers to build and evolve a next-generation Search Platform that powers intelligent, scalable, and low-latency retrieval across massive enterprise datasets.

Our systems span the full lifecycle of search—from data ingestion and indexing to retrieval, ranking, and real-time query execution. You will work at the intersection of distributed systems, information retrieval, and applied ML/LLMs, contributing to both platform capabilities and search relevance improvements at scale.

You will collaborate closely with engineering, product, and data science teams to design and deliver high-quality solutions while continuously improving system performance and user experience.

Value You Deliver

• Design and develop scalable backend services and REST APIs using Java and Spring Framework
• Build and optimize indexing pipelines and query systems for large-scale datasets
• Develop components for distributed search and data processing systems
• Implement hybrid search techniques (keyword + vector/semantic retrieval)
• Contribute to event-driven architectures and data pipelines using streaming technologies
• Integrate ML/LLM-based components into production search workflows
• Improve system performance through tuning, debugging, and root cause analysis
• Participate in end-to-end development lifecycle: design, development, testing, and maintenance
• Write high-quality, testable code using best practices such as TDD
• Collaborate in Agile (Scrum) teams, contributing to sprint planning, reviews, and design discussions

What you bring

• Bachelor’s degree in Computer Science or related field
• 5+ years of experience in backend or distributed systems development
• Experience with large-scale data processing systems is a plus

Technical Skills

Core Programming & Frameworks

• Strong proficiency in Java (Java 17+)

• Understanding of event-driven architectures and message processing
• Experience working with JSON data (Jackson or similar libraries)

Data Storage

• Experience with NoSQL systems (preferably Cassandra)
• Understanding of distributed data models and query optimization

Infrastructure & Tooling

• Experience with build tools (Maven) and version control (Git)
• Familiarity with Kafka or similar message brokers is a plus
• Exposure to distributed file systems (HDFS) is a plus

Testing & Quality

• Experience with unit testing frameworks (JUnit, Mockito)
• Understanding of test-driven development (TDD)

Value Competencies

• Strong ownership and accountability for delivering high-quality solutions
• Ability to collaborate effectively across teams and stakeholders
• Curiosity and willingness to learn modern search, ML, and LLM technologies
• Focus on performance, scalability, and reliability
• Continuous improvement mindset with strong engineering discipline

Where you belong

We are part of the CTO organization focused on building a world-class Search Platform that powers enterprise discovery and procurement use cases at scale. Our team works on challenging problems across distributed systems, search relevance, and AI-driven retrieval—combining traditional information retrieval techniques with modern ML and LLM-based approaches. We prioritize scalability, observability, and real-world impact, while fostering a culture where engineers can grow and do their best work.
