We are looking for a Software Engineer to join Glean’s Data Foundations team — the group that owns 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. Your work will directly determine the quality, freshness, and trustworthiness of the knowledge that every Glean user interacts with every day.

  • 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.
  • 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.
  • 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.
  • Prior work on enterprise connectors, search/indexing, information retrieval, or security-sensitive systems is a strong plus.
  • We offer a comprehensive benefits package including competitive compensation, Medical, Vision, and Dental coverage, generous time-off policy, and the opportunity to contribute to your 401k plan to support your long-term goals.
  • When you join, you'll receive a home office improvement stipend, as well as an annual education and wellness stipends to support your growth and wellbeing.
  • We foster a vibrant company culture through regular events, and provide healthy lunches daily to keep you fueled and focused.
