Software Engineer, Enterprise Knowledge Platform
Perplexity · San Francisco
About this role
**Software Engineer, Enterprise Knowledge Platform** ## About the Role The Enterprise Knowledge Platform team builds the data and action layer that connects Perplexity’s agents to the systems where enterprise work happens. Useful agents need more than API access—they must discover the right tools, understand an organization’s data and terminology, and act reliably within permissions. You’ll build a consistent platform that brings native connectors, MCP servers, and CLI-backed tools together. This is a product and platform engineering role with end-to-end ownership—from designing connector infrastructure and semantic models to shipping the customer experiences for discovering, connecting, and activating integrations. You’ll also work on the runtime that executes tool calls, the knowledge layer that makes enterprise context reusable across connectors, and the developer/marketplace foundations that help the ecosystem grow. ## Key Responsibilities - Own the connector runtime that registers, hosts, and executes native connectors, hosted MCP servers, and CLI-backed tools through a consistent agent-facing interface. - Build the semantic and knowledge layer (tool/entity schemas, capability metadata, relationships, organization-specific terminology, and reusable corrections) while preserving provenance and source-system permissions. - Design discovery, search, and recommendation systems to help agents find relevant tools and context, and help users/organizations choose the right integrations. - Build the marketplace and activation experience end to end: browsing, recommendations, installation, configuration, admin enablement, and ongoing adoption. - Ensure connector execution is reliable and observable (structured results, retries, idempotency, pagination, rate-limit handling, and recovery from partial failures). Own reliability targets, production monitoring, and incident response. - Implement authentication, credential isolation, and permission enforcement—partnering with Trust & Governance, Security, and Backend Platform on shared policies and tenant boundaries. - Build onboarding and publishing paths for internal teams and external partners, including schemas, test fixtures, validation, review, and versioning. ## Qualifications - 4+ years of software engineering experience, with a track record of owning complex backend systems from design through production operation. - Strong system design skills for reliable, scalable platforms integrating heterogeneous APIs/services with clear security and isolation boundaries. - Proficiency in a backend language such as Python, Go, or Rust, plus hands-on experience with AWS and Kubernetes. - Deep expertise in at least one area: - Connector runtimes, API platforms, or MCP servers (authn/authz) - Schema design, semantic modeling, or knowledge systems - Search, ranking, recommendation, or tool discovery - Marketplaces, developer platforms, or enterprise onboarding/activation - Ability to work across backend infrastructure and customer-facing product experiences, translating integration requirements into clear APIs, developer tools, and workflows. - Strong technical judgment in security-sensitive distributed systems (credential isolation, permission correctness, failure behavior, performance, usability, and delivery speed). - Experience leading ambiguous, cross-team initiatives from architecture through adoption—setting technical direction and improving engineering quality through mentorship. *
