Job summary

Dow Jones seeks a Senior Machine Learning Engineer to design and build the core systems behind our LLM applications, including orchestration, tooling, and evaluation harnesses. You will work on production-grade AI features, focusing on reliability, speed, and cost management, reporting to the Director of Data Science & Insights.

You will design multi-step LLM workflows, create reusable tooling, and build dashboards and alerts to monitor accuracy, latency, and hallucinations while collaborating

Qualifications

• 2+ years of software/ML engineering experience, including at least 1 year building LLM systems in production.
• Expert Python, hands-on with LLM APIs and cloud platforms (AWS, Snowflake, Vertex).
• Deep experience orchestrating multistep LLM workflows as execution graphs (e.g. LangChain/LangGraph).
• Experience building agent harnesses: memory compression, skill disclosure, and tool design.
• Strong prompt engineering: tuning, versioning, and evaluation of prompts and model configs.
• A proven track record in AI evaluation, observability, and retrieval over enterprise data.
• Ability to explain complex AI concepts and tradeoffs clearly to nontechnical stakeholders.
• Fluency with agentic coding tools (e.g. Claude Code) and their architecture patterns (a strong plus).

Responsibilities

• Design and build the orchestration, prompting, and workflow layers behind production AI features.
• Create composable tools and integrations, including retrieval and MCP servers and clients.
• Build evaluators, dashboards, and alerts that track accuracy, latency, cost, and hallucination.
• Harden the platform for production scale: caching, reliability, incidents, and model rollbacks.
• Set the technical bar through architecture decisions, design reviews, and mentoring.
