About The Position

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.
