Join to apply for the Senior Software Engineer (f/m/d) role at Scheer Group.
As a Senior Software Engineer, you are responsible for designing and developing IMCs platform architecture covering both the software and infrastructure aspects of the platform with a key focus on its platform search feature. The role is expected to work closely with the Tech leadership and product teams to define short- and long-term improvements to address the growth of our customer experience.
What You’ll Be Doing
* Platform & Application Engineering:
o Partner with Software Architects, Tech Leaders, and Product Managers to analyze and transform business requirements into robust software specifications.
o Design and develop highly scalable, secure, and low-latency RESTful APIs for our platform.
o Contribute to the design of distributed, cloud-native application components, ensuring resilience, observability, and operational excellence.
o Actively participate in architecture decisions and contribute to short- and long-term technical strategies.
o Build, operate, and continuously improve infrastructure and platform services following DevOps and GitOps principles.
o Collaborate in small, agile, cross-functional teams and contribute to knowledge sharing and mentoring.
* Search Technology (Full‑Text & Vector):
o You will be a domain lead or key contributor for the platform’s search capabilities. Responsibilities include:
+ Design, implement, and optimize search pipelines covering full‑text indexing, retrieval, ranking, and faceting.
+ Vector‑based semantic search (ANN: HNSW, IVF, PQ, graph‑based indexing, hybrid fusion techniques).
+ Own the architecture and lifecycle of search indexes across multiple modalities (documents, metadata, embeddings).
+ Optimize and tune search engines and vector databases, such as Elasticsearch/OpenSearch, Pinecone, FAISS, etc.
+ Optimize system‑level performance, including indexing throughput, refresh strategies, segment merging, query latency, ranking accuracy, and memory/CPU footprint.
+ Design hybrid retrieval strategies combining BM25/TF-IDF with vector similarity (RRF, fusion scoring, re‑ranking models).
+ Implement monitoring and observability for search systems, including relevancy metrics, degradation detection, and anomaly tracking.
What You’ll Need
* 5+ years of professional experience in agile software development.
* Strong expertise in Java, Spring Framework, and Spring Boot.
* Experience with Containers and Kubernetes or similar technologies (e.g., Docker).

* Advocate of Clean Code and the DevOps culture (e.g., GitLab CI, Jenkins, Gradle, Maven, Ant, Gulp, Ansible, Salt, Terraform, Prometheus, Kibana, Grafana, Logstash, Beats, Helm).
* Experience with cloud‑native development technologies and practices is a plus (IaC, GitOps, DevOps, Cloud Computing).
* Knowledge of Microsoft Azure, AWS or similar cloud computing platforms is a plus.
* Fluency in English is mandatory; Fluency in German would be a big advantage.
* Bring a positive and solution‑oriented mindset.
* Self‑motivated and self‑managing, with strong organizational skills.
* Great communicator that can easily explain ideas and engage people while translating business requirements into technical solutions.
What’s In It For You
* You can actively participate in and drive agile approaches and processes for improving our cloud native strategy.
* You build and operate platform and infrastructure core services in a distributed service‑oriented architecture in a small autonomous agile team.
* Flexible working hours, flat hierarchies, and a cooperative culture.
