Search Platform Administrator

We are seeking a Search Platform Administrator to join a team that delivers solutions to a large, mature enterprise organization. The role focuses on designing, operating, and optimizing a scalable search platform that is a critical part of high-availability, data-intensive systems. This position involves close collaboration with backend and infrastructure teams, offering the opportunity for long-term, remote cooperation.

Responsibilities:

• Install, configure, and maintain Elasticsearch / OpenSearch clusters.

• Manage indices, mappings, analyzers, index/component templates, and ILM policies.

• Integrate the search platform with backend applications (e.g. Spring Data Elasticsearch).

• Optimize cluster performance (shards/replicas, refresh interval, heap, GC, thread pools).

• Monitor and troubleshoot cluster health, logs, metrics, and alerts; resolve yellow/red states and shard allocation issues.

• Implement search use cases such as full-text search, pagination, sorting, and boosting.

• Design and configure cluster architecture (nodes, shards, replicas).

• Create and maintain queries (DSL), CRUD operations, aggregations, filtering, and sorting.

• Configure analyzers, tokenizers, and ingest pipelines, including Polish language analysis.

• Manage security (users, roles, index permissions, DLS/FLS, TLS/mTLS, certificate rotation).

• Plan and execute backups and restores (snapshots), including repository configuration (FS / S3).

• Perform upgrades and rolling upgrades while ensuring high availability.

• Work with the Elastic Stack ecosystem (Logstash, Beats, Kibana).

Requirements:

• Hands-on experience administering Elasticsearch and/or OpenSearch clusters.

• Strong understanding of search engine architecture and internals.

• Experience with performance tuning and production troubleshooting.

• Solid knowledge of DSL queries and full-text search concepts.

• Experience with security configuration (TLS, roles, permissions).

• Ability to work with large-scale, highly available systems.

• Communicative level of English (spoken and written).

Nice to have:

• Experience in enterprise-scale projects.

• Cloud experience (AWS / Azure / GCP).

• Collaboration with backend teams (Java / Spring-based systems).

What we offer:

• Fully remote work.

• Participation in a stable, long-term enterprise project.

• Opportunity for long-term cooperation and involvement in further platform development.

• Real impact on the architecture and quality of a critical search platform.

• Collaboration with experienced engineering teams in a mature technical environment.
