Senior AI Platform Engineer - Knowledge & Reasoning

Overview

Senior AI Platform Engineer focused on building shared knowledge and reasoning capabilities for Esko’s centralized AI platform.

What you'll do

• Design how knowledge is represented for both AI agents and deterministic validators and for human curation.
• Build and operate platform services for ingesting, curating, retrieving, and versioning knowledge.
• Define how semantic retrieval, deterministic validation, and human review work together for applicability, uncertainty, conflicts, and escalation.
• Design and implement APIs and tools to apply, validate, and explain contextual knowledge.
• Build evaluation suites for retrieval quality, applicability, conflict/ambiguity handling, and explanation quality.
• Take end-to-end ownership of security, tenant isolation, reliability, observability, performance, and compatibility.

What you'll need

• Strong production systems software engineering experience using Python, TypeScript, Java, or similar.
• At least 5 years’ experience in a software engineering role, preferably with platform/API/shared services ownership.
• Experience building knowledge/retrieval/rule systems other teams depend on and choosing appropriate formalisms.
• Practical experience with RAG, information extraction, and structured validation (JSON Schema, Pydantic, or equivalent).
• Judgement for reasoning about applicability, exceptions, missing evidence, and ambiguity, including when to require human review.
• Ability to construct evaluation datasets and clearly document modelling decisions, tradeoffs, and failure modes.
• Undergraduate, Master’s, or PhD degree in Computer Science/ML/Data Science/AI or related disciplines.
