Experienced Senior Context Engineer, Digital Transformation & Innovation

Job Summary:

The Experienced Senior Context Engineer is a senior individual contributor responsible for designing and building the 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 Experienced Senior Context Engineer works 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. The role reports to the Context Engineering Manager and operates within the Advantage SDLC, firm policies, and security standards.

Job Duties:

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
