Engineering Organization & Culture

At Bullish we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform where security and compliance are the foundational core requiring a commitment to technical excellence that goes beyond simply delivering code. We operate as a global engineering organization setting a high bar in a demanding environment for those driven to do the best work of their careers alongside world-class peers.

We value engineers who treat development as a craft and own the outcome from concept to deployment. You will be expected to navigate the unknown bring structure to ambiguity and help shape the frameworks and processes that drive our global teams forward. We refuse to compromise on quality and seek problem solvers who thrive on high-impact technical challenges.

The Team: AI & Data Platform

The AI & Data Platform team powers intelligence across the Bullish ecosystemfrom our institutional-grade cryptocurrency exchange to CoinDesks media data and indices businesses. We build the infrastructure that transforms raw data into governed trustworthy assets and deploy AI systems that meet the reliability standards our institutional clients expect.

We operate at the intersection of data engineering semantic modeling and applied AIdelivering solutions across the enterprise spanning the full breadth of Bullish operations from trading floors to treasury compliance to market intelligence.

As we scale our AI capabilities we are building a knowledge-centric architecture: one where data is not just stored and queried but understoodby humans and agents alike. This requires a new kind of technical leader who can bridge the worlds of advanced data infrastructure and production AI systems. This is a team where AI is treated as serious engineering not experimentation.

The Role

This is an enterprise-wide technical leadership role reporting to the Head of AI & Data Platform. Depending on experience this will be filled at Director or Lead Engineer level. You will own the architecture and delivery of systems that make Bullishs data not just accessible but intelligible to business users through conversational analytics and to AI agents through governed semantic and knowledge layers.

The industry is at an inflection point. Google Clouds Agentic Data Cloud BigQuery Graph Knowledge Catalog and MCP-native database tooling are redefining how data platforms serve autonomous agents. We need a technical leader who understands this shift deeplynot as a trend to monitor but as an architecture to build.

What Youll Do

• Knowledge Architecture & Semantic Infrastructure. Design and own the enterprise knowledge layerthe governed semantic models ontologies and knowledge graph structures that ground both human analytics and AI agents in a single source of truth. Define how business meaning flows from glossaries through data models to agent context.

• Conversational Analytics. Lead the strategy and delivery of natural-language interfaces to business data. Move beyond dashboard-driven BI toward systems where stakeholders query complex datasets conversationally and receive context-rich citation-backed answers from governed semantic layers.

• Agentic Data Platform. Architect the infrastructure that enables AI agents to discover reason over and act on enterprise data. This includes MCP-based tool connectivity agent-facing data services and integration with emerging capabilities such as BigQuery Graph Knowledge Catalog and the Google Cloud Data Agent Kit.

• Advanced Data Infrastructure. Drive adoption of graph databases knowledge bases and hybrid query engines that support multi-hop reasoning entity resolution and relationship-aware analytics. Evaluate and integrate technologies at the intersection of structured data knowledge graphs and generative AIincluding GraphRAG patterns and vector-augmented retrieval.

• Enterprise Data Strategy. Partner with domain stakeholders across trading treasury compliance market intelligence and media to ensure the data platform serves the full breadth of the business. Own cross-domain data modeling standards and govern the semantic layer that underpins all analytical and AI workloads.

• Evaluation & Trust. Establish evaluation frameworks for AI systems that consume platform dataensuring groundedness factual consistency and output reliability. Build the measurement infrastructure that lets the organization trust what agents produce.

• Technical Leadership. Set architectural direction mentor engineers drive build-vs-buy decisions and represent the teams technical vision to senior stakeholders. At Director level operate as a peer to engineering directors across the organization; at Lead level drive technical excellence and influence architectural decisions across the platform.

What Youll Bring

• Data & AI Platform Experience. 7 years in data engineering analytics or AI platform roles. Director-level candidates will have 3 years in a technical leadership position (Director Principal Staff or equivalent); Lead Engineer candidates will have demonstrated technical ownership and mentorship in senior IC roles. Demonstrated experience building and operating enterprise-scale data platforms in production.

• Conversational Analytics & Semantic Layers. Direct experience building natural-language query systems over structured data. Deep understanding of why semantic layers governed definitions and business context are prerequisites for accurate conversational analyticsnot afterthoughts.

• Knowledge Graphs & Advanced Data Models. Hands-on experience with graph databases knowledge graphs or ontology-driven data architectures. Understanding of how graph structures enable multi-hop reasoning entity resolution and context grounding for AI agents.

• Experience with at least 3 of the following:
  Graph databases and query languages (Neo4j TigerGraph Amazon Neptune or Big-Query Graph)
  Knowledge graph construction and ontology modeling (RDF/OWL property graphs taxonomy design)
  GraphRAG architectures (graph-augmented retrieval for grounded generation)
  Semantic layer and business intelligence platforms (Looker dbt Semantic Layer AtScale)
  Vector databases and hybrid retrieval (Qdrant Pinecone pgvector AlloyDB vector search)
  Cloud data platforms at scale (BigQuery Snowflake Databricks Spanner)
  Data cataloging and governance (Google Knowledge Catalog/Dataplex Collibra Alation Atlan)
  MCP (Model Context Protocol) for agent-data connectivity

• Agent & AI Systems Expertise. Experience designing systems where AI agents interact with data infrastructureincluding tool-use patterns structured output generation and agent orchestration frameworks. Understanding of evaluation methodology for AI systems (groundedness factual consistency hallucination measurement).

• Cloud Infrastructure. Strong GCP experience preferred (BigQuery Cloud Composer Vertex AI Dataplex/Knowledge Catalog). Comfort operating in regulated multi-region cloud environments with strict data governance requirements.

• Engineering Rigor. Track record of building observable testable well-documented systems. Experience with CI/CD for data and ML pipelines data quality frameworks and infrastructure-as-code practices.

• Communication & Influence. Ability to translate between deep technical architecture and business strategy. Comfortable presenting to C-suite stakeholders aligning cross-functional teams and making the case for long-term platform investments. You write clearly and think in systems.

Nice to Haves
