Become a Senior SRE for Bloomreach!

Join the Fuse team — the team responsible for the item data management capabilities that connect Bloomreach Data Hub with Marketing, Search, Recommendations, and emerging Loomi agent use cases.

Fuse owns and evolves the systems behind Data Hub item collections: ingesting items data, transforming and validating it, managing data schemas and lifecycle, and distributing data reliably to downstream Bloomreach products. Item collections provide a unified source of data that can be used across all Bloomreach products.

• Unified items data pipelines: processing records into structured items and keeping data synchronized with Marketing and Search destinations.
• Catalog APIs and lifecycle management: customer-facing and internal APIs, catalog creation and naming, schemas, destinations, migrations, and backward-compatible evolution.
• Scalable storage and indexing: operating and improving systems built on PostgreSQL, Bigtable, Elasticsearch, Solr.
• Reliable jobs execution: submission, queueing, execution, progress reporting, retries, cancellation, rate limiting, and operational tooling.
• Cross-product capabilities: catalog data triggers, multi-dimensional data support, custom item types, catalog data enrichment, recommendations, and semantic catalog profiles for agentic use cases.

As a Senior SRE, you will be the team’s reliability and operability leader. You will work alongside backend engineers, embedded QA, Product, and Engineering Management to make complex product-data systems observable, scalable, safe to release, and straightforward to operate.

Fuse embraces AI-assisted engineering. We expect engineers to use modern coding agents thoughtfully to accelerate investigation, development, testing, documentation, and operational work while retaining full ownership of correctness, security, and production outcomes.

Working from one of our Central European offices (Bratislava, Prague, or Brno), or remotely (Czechia, Slovakia) on a full-time basis, you’ll become a core part of the Engineering organization.

What challenge awaits you?

As a P3 Senior SRE at Bloomreach, you are an independent reliability professional who can turn ambiguous operational problems into measurable improvements and lead initiatives end-to-end with minimal day-to-day guidance.

Your challenge will be to make Fuse’s distributed data platform dependable across the complete data path:

customer or integration → Data Hub API → records and transformations → items → asynchronous jobs execution engine → storage and indexes → Marketing, Search, Recommendations, and Loomi consumers

Your responsibilities

a. Platform reliability and observability

• Own and improve the reliability posture of Fuse services, workers, APIs, queues, storage systems, and destination synchronization pipelines.
• Establish meaningful SLIs, SLOs, and error budgets for customer-facing APIs, asynchronous jobs, catalog data freshness, destination synchronization, and indexing.
• Build end-to-end observability across Data Hub item collections, from API request and job submission through processing, persistence, indexing, and downstream delivery.
• Ensure engineers can trace a workspace, item collection, catalog, or job across services without manually correlating disconnected logs and database records.
