Database Engineer (DBE) – Enterprise Open-Source Support
Location : Remote (preferred South / Central America or US TIme Zones)
Department : Engineering - Open Source Database support
Reports to:CTO / VP EngineeringAboutDeep. BI
We provide enterprise support and consulting for open‑source analytics and data infrastructure platforms such as Apache Druid, Apache Flink, Star Rocks and other emerging technologies. Our customers run mission‑critical, high‑volume systems and rely on us to keep them fast, stable, and available. We’re a small, world-class expert, remote‑first team working across multiple time zones (US, Brazil, Europe, India, Philippines), supporting 100+ customer environments with SLAs ranging from advisory support to 24/7 incident coverage.Role Overview
As a Database Engineer (DBE), you will be the core L3/L4 technical expert responsible for solving the most complex database problems our customers face in production with an emphasis on supporting Star Rocks clusters. You’ll dive deep into query optimization, ingestion pipelines, schema design, and HA/DR configuration — ensuring that large-scale analytical systems remain reliable, scalable, and performant.While your primary focus is database internals and advanced troubleshooting, we value engineers with broader skills — knowledge of Dev Ops, Infrastructure, security or SRE Practices is highly appreciated and will make you even more impactful.Key Responsibilities
Advanced troubleshooting (L3/L4):Diagnose and resolve complex issues in Star Rocks and other OLAP database clusters (performance Bottlenecks, ingestion failures, query regressions)
Performance optimization:Tune queries, schemas, ingestion flows, and configs to maximize efficiency under high load.
Architecture & design support:Work with Solution Architects to shape data models, indexing strategies, and HA/DR approaches.
Incident resolution under 24/7 SLA:Comfortable debugging under SLA pressure and participating in on-call rotations. Act as the escalation point for production incidents, ensuring rapid root cause analysis and fixes.
CVE patching:Apply, validate, and test security patches for database systems in customer environments.
Knowledge sharing:Document best practices, contribute to playbooks, and mentor junior engineers when needed.
Optional / nice-to-have:
Support deployments with Dev Ops engineers (Kubernetes, cloud, automation)
Assist in secure configuration and compliance requirements
Collaborate with developers (DD role) on upstream OSS bug fixes or feature contributions.Requirements
2+ years hands-on experience operating and troubleshooting Star Rocks clusters in larger scale production(not just querying or dashboard usage; no Po Cs)
Proven experience withquery optimization,indexing, schema design, and ingestion pipelines.
Solid knowledge ofdistributed systems concepts(consistency, replication, failover, scaling)
Hands-on experience withhigh availability and disaster recovery setups
Comfort withLinux systems, networking basics and SQL.
Ability toanalyze logs, metrics, and configs under pressure(incident scenarios)
Strong English language communication skills— able to explain technical decisions clearly to engineers and delivery managers both verbally and in writing
Bonus:Experience with Apache Druid, Click House, Ti DB, Apache Cassandra, or similar databases
Bonus : Experience with Kubernetes, cloud infra (AWS/GCP/Azure), or security best practices (RBAC, encryption, IAM).
Bonus : Contributions to open-source database projects.What we offer
