Applied Engineer (Tribal Knowledge) in London

Design and own the agent system that compiles an organization’s tribal knowledge.

About Pavo

Pavo is building Enterprise Superintelligence: compounding systems that take ownership of business outcomes and work with humans to deliver them. We believe that while foundation models are necessary, they are not sufficient. The hard problem is systems intelligence: end-to-end architectures that understand a company’s code, data, and decisions, and improve themselves through experience. We are assembling a small, senior team of researchers and engineers obsessed with systems-first intelligence.

The Opportunity

As an Applied Engineer at Pavo, you will design and own the agent system that compiles an organization’s tribal knowledge — the body of knowledge that nobody has written down — from its own evidence: source code, structured data, internal documents, and conversations. You’ll work hands-on at the level of agent architecture, pipeline design, and the production surface that turns a generative system into one customers can depend on. You’ll partner closely with the Applied Scientist on instrumentation — but the system itself is yours. It is the most consequential thing we build, and idea to production is days.

This is a senior, individual-contributor role. Everyone on the team joins as a Member of Technical Staff — with the scope, autonomy, and end-to-end ownership that title implies.

What You’ll Build

• Hierarchical Agent Architecture: Design how a main agent coordinates sub-agents, tools, and skills — deciding where deterministic scaffolding beats prompting and where prompting is the right tool.
• The Synthesis Pipeline: Own the multi-stage system that turns heterogeneous private evidence into a verifiable knowledge artifact.
• Deployment & Rollout: Build scheduled regeneration, quality and reliability gates, blue/green rollout, and customer-facing version control of compiled knowledge artifacts.
• Observability & Debuggability: Structured traces of agent runs, replay/debug tooling, cost and latency budgets, and regression detection on releases.
• Reliability as a First-Class Property: Treat run-to-run variance as a defect class equal to incorrectness, and build the engineering practice that reduces it.
• Eval & CI Infrastructure: Reproducible, automated evaluation that feeds signal back into the deploy loop.

What We Are Looking For

We are looking for an engineer who has shipped dependable production systems and is hungry to do it at the edge of what current agentic frameworks can do.

Core Qualifications

• Senior Track Record: 8+ years building and operating production systems.
• Production Engineering Chops: You ship Python systems that other engineers want to extend.
• Hands‑On with an Agentic Framework: Depth with at least one — Anthropic tool use, OpenAI Agents SDK, Pydantic AI, LangGraph, AutoGen, or equivalent.
• Strong Opinions on Agent Architecture: When to use a single-context agent versus decompose into sub‑agents.
• Deployment Pipelines for ML/LLM Systems: Experience designing and operating rollout, gating, observability, on‑call posture, and regression detection.
• Comfort with Reliability Work: The unglamorous work that turns a flaky agent into a dependable one.
• Pragmatism About Prompts: A hard‑won sense of what’s prompt‑tunable and what isn’t.

Preferred Qualifications

• Built or maintained an LLM evaluation harness in production.
• Familiarity with retrieval / IR systems and the engineering of large-context pipelines.
• Distributed‑systems background — workflow engines (Temporal / Airflow / Prefect), queues, and observability stacks (OpenTelemetry, Datadog, Honeycomb).
• Open‑source contributions to agentic frameworks, eval tooling, or workflow orchestration.

Why Join Us

• Architecture‑Defining Work: The system you design becomes the substrate for everything we ship downstream.
• Short Loop: Work directly with the Applied Scientist on instrumentation and with the founders on platform direction.
• Real Ownership: Genuine ownership in a small, technically deep team.
• Foundational Space: The private knowledge layer will reshape how AI agents operate inside organizations.
