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. 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.

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; 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; Improve availability, scalability, and operability of catalog data across PostgreSQL/Cloud SQL, Bigtable, Elasticsearch, GCS, Kafka; Develop safeguards for full replacements, delta updates, deletions, schema changes, destination changes, and catalog reindexing; Define and automate data-consistency checks; Own and evolve Kubernetes configuration and operational infrastructure for Fuse components; Improve deployment automation, progressive rollout, rollback, and validation; Maintain CI/CD pipelines; Participate in and help improve the Fuse L3/on-call rotation; Lead incident investigation, mitigation, stakeholder communication, and follow-up; Help Fuse meet 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 design of new Fuse capabilities; 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

Impact: you can show how your reliability work improved customer outcomes, engineering velocity, deployment confidence, or operational sustainability; you have introduced practices or tooling that changed how a team builds and operates production systems; you can define meaningful reliability measures and demonstrate improvement using data; Ownership: you embrace the 'you build it, you run it' principle and remain accountable from design through production operation; you can lead ambiguous reliability initiatives without requiring a fully prescribed solution; you take incidents from detection through mitigation, root-cause analysis, and prevention; you are cost-aware and use telemetry, capacity planning, and architecture—not guesswork—to manage cloud spend; Systematic approach: you treat observability, limits, runbooks, rollback, idempotency, and recovery as part of the product design; you design for partial failure in distributed systems; you distinguish symptoms from root causes and prioritize systemic improvements over repeated manual intervention; you are comfortable working in systems where a single customer operation crosses multiple services, queues, databases, and team boundaries; Data-driven engineering: you use metrics, logs, traces, profiling, and workload data to form and validate hypotheses; you can turn operational telemetry into actionable feedback for developers and Product; you are 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, with practical ability in both being 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.

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.
