About this role

Principal AI Engineer is a full-time hybrid position based in Poland with Elastic, designed for an experienced software professional to lead the production improvement loop for the Context Engine team. This role suits a senior technologist who can combine backend engineering, data science, and product development to manage how AI agents, automations, and skills perform in real-world environments.

Role Overview

The Principal AI Engineer role at Elastic centers on building and refining the knowledge layer utilized by AI agents to interact with enterprise data inside Elasticsearch. Operating within a distributed, async-first team, the professional in this position will write production code in TypeScript, establish evaluation frameworks, and manage telemetry to support safe, data-driven product iterations.

Key Responsibilities

Manage the end-to-end production improvement loop for the Context Engine by identifying failure modes, implementing fixes, and verifying outcomes through telemetry and offline evaluations.
Establish safe iteration procedures for agents and skills, including prompt versioning, rollout strategies, regression coverage, and staged evaluations.
Design system telemetry to capture agent traces, tool calls, and knowledge retrieval data within Elasticsearch to feed dashboards and feedback loops.
Collaborate with data scientists to formulate evaluation strategies, golden datasets, and quality, latency, and cost evaluators.
Review pull requests and designs, mentor engineers in evaluation-driven development, and draft technical proposals to guide the team roadmap.

Requirements

Ten or more years of software engineering experience, including recent years spent operating AI-driven products on production traffic.
Demonstrated history of evaluation-driven product improvement through diagnosing LLM behavior from traces and user feedback.
Practical background in constructing agents with state and memory while iterating on prompts, skills, and tools safely in production.
Familiarity with the Model Context Protocol (MCP), including the publication of public MCP servers and tools.
Experience designing AI system telemetry and conducting end-to-end product experiments.
Strong backend engineering capabilities in either Python or TypeScript for building APIs, stateful workflows, and data pipelines.
