About the role

Software Engineer role on Glean’s Data Foundations team, owning the end-to-end data ingestion and management layer powering Glean’s Search, AI Assistant, and Agent products across thousands of enterprise apps and billions of documents.

Responsibilities

  • Build and scale connectors to a wide variety of SaaS and on-prem systems (Google Workspace, Microsoft 365, Slack, Salesforce, Jira, ServiceNow, GitHub, etc.).
  • Handle full syncs, low-latency incremental updates via webhooks/APIs, rate-limiting, and complex authentication flows.
  • Build advanced capabilities in datasources like actions, live-fetch, and query language support.
  • Transform raw, unstructured enterprise content into rich, structured, permission-aware representations optimized for search and LLM reasoning.
  • Design document schemas and enrichment pipelines (entity extraction, access-graph propagation, redactions, etc.).
  • Expand the capabilities of AI products through deep integrations that allow us to automate tasks, perform complex queries grounded in enterprise data, and enhance our indexed corpus with live data.
  • Own end-to-end correctness, freshness, and performance for petabyte-scale data flows.
  • Solve hard problems in ordering, idempotency, exactly-once processing, backpressure, and retries across distributed queues, workers, and storage.
  • Preserve fine-grained ACLs, deletions, and sensitivity constraints so AI answers are always grounded in what users are actually allowed to see.
  • Partner closely with Search Serving, Product, Platforms, and Security teams to define how enterprise context is exposed to LLMs and agents.
  • Continuously improve observability, alerting, and automation to onboard larger customers and more data sources with confidence.

Qualifications

  • 3+ years building production backend or data infrastructure systems (Java, Go, C++, Python, etc.).
  • Hands-on experience with distributed systems, data pipelines, queues, and large-scale storage (SQL/NoSQL).
  • You think in SLOs, error budgets, failure modes, and correctness guarantees — not just features.
  • Comfortable with strict consistency and permission-modeling challenges.
  • Prior work on enterprise connectors, search/indexing, information retrieval, or security-sensitive systems is a strong plus.
  • Passionate about making AI trustworthy by building the rock-solid data foundation underneath it.
  • Power user of LLMs and AI tools in your own workflow.
