Senior Site Reliability Engineer for Fuse Team

Bloomreach is building the world's premier agentic platform for personalization. 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.

Responsibilities

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; Create and maintain actionable dashboards, alerts, and service health views using Grafana, Prometheus-compatible metrics, OpenTelemetry, PagerDuty, and GCP tooling; Improve capacity planning and autoscaling using workload telemetry, queue depth, processing throughput, latency, memory usage, storage growth, and customer-level traffic patterns; Improve the availability, scalability, and operability of catalog data across PostgreSQL/Cloud SQL, Bigtable, Elasticsearch, GCS, Kafka, and related storage systems; Support catalog placement, routing, index lifecycle, shard management, safe migration, and recovery across multiple Elasticsearch clusters; Develop safeguards for full replacements, delta updates, deletions, schema changes, destination changes, and catalog reindexing; Define and automate data-consistency checks between source records, transformed items, job state, Bigtable, Elasticsearch, and downstream destinations; Own and evolve Kubernetes configuration and operational infrastructure for Fuse components; Improve deployment automation, progressive rollout, rollback, and validation across development and production environments; Maintain CI/CD pipelines with tests, linters, dependency management, security checks, image publication, and release verification; Participate in and help improve the Fuse L3/on-call rotation; Lead incident investigation, mitigation, stakeholder communication, and follow-up for Fuse-owned systems; Facilitate blameless incident reviews and ensure resulting actions address root causes; Help Fuse meet Bloomreach security and compliance requirements, including ISO and SOC 2 controls; Enforce least-privilege access, workload identity, service-level authentication and authorization, secret rotation, encryption, and auditability; Participate early in the design of new Fuse capabilities so reliability, recovery, observability, limits, and operational ownership are defined before implementation; Review designs for failure modes, retry behavior, idempotency, backpressure, ordering, consistency, timeout handling, cancellation, and safe rollout; Coach engineers in production readiness, operational testing, debugging, and sustainable on-call practices

Requirements

Show how your reliability work improved customer outcomes, engineering velocity, deployment confidence, or operational sustainability; Introduced practices or tooling that changed how a team builds and operates production systems; Can define meaningful reliability measures and demonstrate improvement using data; Embrace the you build it, you run it principle and remain accountable from design through production operation; Can lead ambiguous reliability initiatives without requiring a fully prescribed solution; Take incidents from detection through mitigation, root-cause analysis, and prevention; Are cost-aware and use telemetry, capacity planning, and architecture to manage cloud spend; Treat observability, limits, runbooks, rollback, idempotency, and recovery as part of the product design; Design for partial failure in distributed systems; Distinguish symptoms from root causes and prioritize systemic improvements over repeated manual intervention; Comfortable working in systems where a single customer operation crosses multiple services, queues, databases, and team boundaries; Use metrics, logs, traces, profiling, and workload data to form and validate hypotheses; Can turn operational telemetry into actionable feedback for developers and Product; Comfortable analyzing throughput, latency, saturation, error rates, queue behavior, database performance, and storage growth; Strong hands-on experience operating services on Kubernetes in a major cloud environment, ideally GCP; Strong experience with observability and incident diagnosis for distributed systems; Experience with Go or Python, practical ability in both is a strong advantage; Experience operating at least one relational database, preferably PostgreSQL or Cloud SQL; Experience with one or more large-scale data or indexing systems such as Bigtable, Elasticsearch/OpenSearch, Kafka, GCS, or comparable technologies; Experience designing or operating asynchronous job-processing systems, queues, workers, and retry mechanisms; Experience with CI/CD, Infrastructure as Code, deployment automation, and safe database migrations; Understanding of API reliability, rate limiting, backpressure, idempotency, and multi-tenant isolation; Comfort participating in an on-call rotation and responding to production incidents; Ability to work effectively in a distributed, remote-first team; Practical use of AI coding tools to accelerate investigation and implementation without outsourcing engineering judgment; Personal qualities: ownership and accountability, systematic thinking, pragmatism, clear communication, collaborative leadership, customer awareness, continuous improvement, remote-first effectiveness

Nice to have

Experience operating catalog, product-data, ingestion, transformation, or indexing platforms; Experience with large Elasticsearch/OpenSearch clusters, shard management, index lifecycle, routing, or reindexing; Experience with Bigtable or another distributed wide-column database; Experience designing consistency validation across multiple storage or indexing systems; Experience with customer-facing data APIs, high-volume bulk ingestion, or full and incremental synchronization; Familiarity with product catalogs used by search, recommendations, marketing, or personalization systems; Experience coordinating reliability improvements across several engineering teams; Experience working in an environment with ISO, SOC 2, data-isolation, retention, and audit requirements
