AI Engineer – Prompt & Context Engineering (Graph + LLM Comparison)

{ “@context”: “http://schema.org”, “@type”: “JobPosting”, “title”: “AI Engineer – Prompt & Context Engineering (Graph + LLM Comparison)”, “description”: “

Overview

We are hiring an AI Engineer to design and operationalize LLM-driven comparison workflows that produce decision-ready comparison reports across Salesforce orgs and codebases. The role focuses on prompt engineering, context engineering, and agentic orchestration to generate structured outputs (including AST or AST-like representations for code). You will blend deterministic Graph DB reports with non-deterministic LLM insights, and enable human-in-the-loop validation. Salesforce metadata familiarity is a plus; Python is beneficial for automation and tooling.

Work Environment

Hybrid working: The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of Company offices, client sites, and your home; noting that you will be unable to work at home 100% of the time.

Responsibilities

  • Design, iterate, and maintain prompt + context strategies to generate consistent, structured comparison outputs (JSON schemas, diff formats, summaries).
  • Build and run agent workflows to orchestrate multi-step comparison tasks (planning, tool calls, retries, fallbacks, state management).
  • Produce code-aware comparisons using AST or similar structural representations (e.g., class/method-level diffs, dependency summaries, refactor suggestions).
  • Integrate deterministic Graph DB findings (commonality/variation, dependency paths, lineage) into LLM context to improve reliability and traceability.
  • Implement output guardrails: schema validation, format constraints, confidence scoring, and consistency checks across runs.
  • Support MCP-based integrations where required to connect tools, enforce controlled context, and standardize tool interfaces for agents.
  • Partner with Salesforce engineers/architects to validate findings, refine templates, and ensure outputs are reviewable and audit-friendly.

Qualifications & Skills

  • Strong prompt engineering and context engineering (structured prompting, tool/function calling, grounding strategies, hallucination mitigation).
  • Hands-on experience building LLM agents and orchestration (multi-step workflows, state/memory, tool routing, error handling).
  • Ability to generate structured code analysis outputs (AST/parse-tree approaches, semantic diffs, dependency extraction, refactoring insights).
  • Experience combining deterministic outputs (Graph DB queries, rule checks) with non-deterministic LLM reasoning in a controlled pipeline.
  • Python is a strong plus (automation scripts, parsers, report generators, lightweight services).
  • Salesforce metadata understanding is a plus (objects/fields, flows, profiles/permsets, dependency concepts, cross-org comparison needs).
  • Proven experience with Claude for structured outputs and agentic workflows (prompt patterns, tool-use/function calling, long-context strategies).
  • Familiarity with Claude-friendly prompt hygiene: explicit schemas, deterministic formatting, step constraints, and robust self-check prompts.
  • Experience using Claude in MCP-based tool ecosystems (defining tools, controlling context sources, safe orchestration patterns).

EEO & Compliance

We are committed to an inclusive recruitment process. We will offer an interview to all candidates who declare they have a disability and meet the minimum essential criteria for the role.
