Member of Technical Staff (Software Engineer, Connector Platform)

Perplexity; San Francisco (CA); On-site; USD 220,000 - 405,000; Full time

Job summary

Perplexity is seeking a Connector Platform Engineer to build the data layer powering agents across hundreds of integrations. You will design and implement the connector runtime, host MCP servers, and CLI-backed tools behind a single agent-facing interface.

You will extend the semantic layer, define tool discovery, ensure robust agent loops with retries and observability, and work with Security on credential isolation.

Qualifications

• Experience designing and building backend systems that run in production.
• Strong system design skills with scalable architectures and API integrations.
• Proficiency in Python, Go, or Rust and multi-language environments.
• Hands-on cloud infra experience (AWS, Kubernetes).
• Knowledge of OAuth/authorization, API connectors, or LLM agent tooling.
• Security-minded with safe trade-offs; collaborative problem solver.

Responsibilities

• Own design and implementation of the connector runtime and hosted tools.
• Extend semantic layer with schemas and metadata.
• Design tool-discovery and tool-selection surfaces for agents.
• Ensure agent loops are robust with retries, observability, and idempotency.
• Define authentication and credential isolation patterns for connectors.
• Build onboarding path with fixtures and evaluation suites.
• Set SLAs, observability, and incident response for an always-on integration surface.
• Collaborate with product and AI teams on interfaces and patterns.

Job description

About The Role

The Connector Platform team builds the data layer that lets Perplexity's agents reach into the world's software. This team owns the systems that turn hundreds of heterogeneous integrations (native, MCP, CLI, first-party, and third-party APIs) into one unified, reliable, well-typed surface that agents can call with confidence.

About The Role

The Connector Platform team builds the data layer that lets Perplexity's agents reach into the world's software. This team owns the systems that turn hundreds of heterogeneous integrations (native, MCP, CLI, first-party, and third-party APIs) into one unified, reliable, well-typed surface that agents can call with confidence. The connector platform is the core layer that forms the knowledge layer for Computer: it is how the agent discovers what tools exist, understands what each one means, decides which to call, and grounds its reasoning in real, permissioned, up-to-date enterprise data. We maintain a knowledge layer above connectors that pushes and pulls context into them, rather than letting each connector hoard org knowledge on its own, making Computer the source of truth for institutional knowledge. Models are commoditizing; grounded, actionable, permissioned access to a customer's real systems is not. When this layer is fast, accurate, and semantically rich, every agent built on top of it gets smarter; when it is weak, no amount of model quality compensates.

Key Responsibilities

• Own the design and implementation of the connector runtime, the system that registers, hosts, and executes built-in connectors, hosted MCP servers, and CLI-backed tools behind a single agent-facing interface.
• Build and extend the semantic layer: tool and entity schemas, capability metadata, relationship modeling, and the mechanisms for capturing and applying organization- and account-specific corrections and knowledge.
• Design the tool-discovery and tool-selection surfaces that agents use to find the right connector and call it correctly, optimizing for both model accuracy and context efficiency.
• Make agent loops robust: structured results, partial-failure and retry semantics, idempotency, pagination, rate-limit handling, and observability into every tool call an agent makes.
• Define authentication, authorization, and credential-isolation patterns for connectors (OAuth flows, BYOK, per-org credential boundaries), partnering with Security and Backend Platform on defense-in-depth.
• Build the connector onboarding path (schemas, fixtures, and evaluation suites) so new connectors ship with measurable quality rather than hope, and drive the eval metrics that tell us a connector actually works inside agent loops.
• Set the technical bar for connector reliability and operability: SLAs, observability, error-rate monitoring, and incident response for an always-on, high-fan-out integration surface.
• Partner with product and AI teams to define clear connector interfaces and integration patterns so new agent capabilities can reliably build on the shared platform.

Qualifications

• Experience designing and building backend systems that run in production (typically 4+ years for mid-level, more for senior and staff).
• Strong system design skills, with a track record of building efficient, reliable, and scalable architectures, ideally including API integration, gateway, or platform-style systems with many heterogeneous downstreams.
• Strong proficiency in at least one backend language such as Python, Go, or Rust, and the ability to work effectively in a multi-language environment.
• Hands-on experience with modern infrastructure (for example AWS, Kubernetes, and related cloud technologies).
• Depth in at least one of: OAuth and authorization protocols, API/connector or MCP-server development, schema and semantic modeling, or building tooling and evaluation for LLM-based agents.
• Comfort working in security-sensitive areas (auth, authorization, credential isolation) and making pragmatic trade-offs between safety, simplicity, and velocity.
• Collaborative mindset and eagerness to solve hard, ambiguous problems alongside other experienced engineers.
