Experienced Senior Context Engineer, Digital Transformation & Innovation

About the Role

The Experienced Senior Context Engineer is a senior individual contributor responsible for designing and building reusable context assets that power BDO Advantage’s AI-native product and process development. This role owns complex context and knowledge work—skill libraries, agent-instruction standards (CLAUDE.md and equivalents), prompt and context patterns, and retrieval-grounding corpora—and establishes conventions and quality standards that other engineers follow. The role operates with a high degree of autonomy, provides technical guidance and mentorship to junior and mid-level engineers, and partners closely with the AI Engineering Manager and product teams to ensure assurance domain knowledge is captured as high-quality, governed, agent-consumable context.

Responsibilities

• Context & Knowledge Engineering
  • Designs and builds complex, reusable context assets—skill libraries, agent-instruction files (CLAUDE.md and equivalents), and prompt and context patterns—for use across DT&I products.
  • Serves as a senior technical resource on context-as-code practice, establishing conventions, inheritance, and versioning standards for the team.
  • Codifies BDO assurance domain knowledge (AKB) into structured, retrievable, governed knowledge with appropriate provenance and citation discipline.
  • Reviews context and skill contributions from other engineers for quality, security, and reuse.
  • Evaluates and pilots emerging context-engineering tools and frameworks to improve grounding quality and developer productivity.
• Retrieval & Grounding Engineering
  • Designs and tunes retrieval pipelines (chunking strategy, embeddings, hybrid search, re-ranking, metadata filtering) for accuracy, cost, and latency using Azure AI Search and vector stores.
  • Owns retrieval-corpus curation and lifecycle management including source selection, freshness, versioning, and retirement of stale knowledge.
  • Builds grounding evaluation, regression testing, and quality metrics for retrieval-augmented features.
• Context Quality, Evaluation & Enablement
  • Defines and runs evaluation for context quality and grounding fidelity across products.
  • Contributes context scaffolding and standards for the Advantage Forge citizen-engineer program and product teams.
  • Mentors junior and mid-level engineers on context-engineering practice and maintains team documentation.
• Risk Management
  • Ensures context assets and grounded knowledge comply with firm security, privacy, and regulatory standards (SOC 2, PCAOB AS 2201, QC 1000, ISO 27001).
  • Prevents sensitive or restricted data from entering prompts, corpora, or model context, and maintains traceability of grounded knowledge.
• Performs other duties as assigned, including willingly accepting a share of less desirable assignments.
• Supervisory Responsibilities
  • Provides technical leadership and mentorship to engineering and development team members.
  • Reviews and provides feedback on the work of other engineers.

Requirements

• Education
  • High School Diploma/GED, required.

• Experience
  • Five (5) or more years of experience in software, data, or AI engineering, or related technology fields, required.
  • Three (3) or more years of experience building LLM context, retrieval-augmented generation (RAG), or knowledge-management systems, required.
  • Experience defining reusable engineering assets, patterns, or technical standards, required.
  • Experience mentoring or providing technical guidance to other engineers, preferred.
  • Experience delivering AI or knowledge solutions in professional services, assurance, or accounting industries, preferred.
• License/Certifications
  • Microsoft Certified: Azure AI Engineer Associate, or equivalent, preferred.

Skills

• Strong knowledge of Microsoft Azure AI services including Azure AI Foundry, Azure OpenAI, and Azure AI Search, required.
• Strong understanding of LLM context windows, prompting, retrieval, and grounding, and how each affects accuracy, cost, and reliability, required.
• Experience with retrieval and vector technologies (embeddings, hybrid search, re-ranking, indexing), required.
• Experience with agent-instruction and skill systems (CLAUDE.md and equivalents) and Markdown-based knowledge structures, required.
• Experience with agentic development tooling (Claude Code or equivalent), Git-based workflows, and .NET/C# and/or Python, preferred.
• Deep knowledge of context engineering, retrieval design, and grounding for production LLM systems.
• Ability to work independently on complex, ambiguous problems and provide technical guidance to others.
• Ability to translate subject-matter expertise into machine-consumable knowledge.
• Excellent problem-solving skills with a focus on accuracy, reliability, and grounding quality.
• Strong communication skills with the ability to convey technical concepts to technical and non-technical audiences.
• Self-directed with the ability to manage multiple priorities and competing deadlines.
• Collaborative mindset with the ability to build relationships across teams.
• Ability to travel up to 10%.
