Staff Data Engineer - unifying fragmented data from HubSpot, financial systems, and HRIS into a single, AI-augmented source of truth for executive decision-making. As Staff Data Engineer, you'll be a foundational technical hire, working closely with the Sr. Director of Data Platform & Analytics to design and build the real-time, AI-ready data infrastructure that powers this platform. This is a hands-on role for someone who wants to build from the ground up, not maintain what already exists.
Key Responsibilities- Design, build, and own near real-time data pipelines (CDC, streaming ingestion, event-driven architectures) as the backbone of the platform's data flow
- Evaluate, implement, and maintain vector database infrastructure and embedding pipelines to support AI-augmented use cases (semantic search, retrieval-augmented generation, AI agents acting on company data).
- Design and build ELT/ETL pipelines ingesting data from our platform, financial platforms, CRM (HubSpot) and HRIS, feeding both real-time and batch use cases.
- Partner with the Sr. Director to architect the underlying warehouse/lakehouse as a supporting system of record - the storage layer beneath the streaming and AI infrastructure.
- Build lightweight transformation layers (e.g., dbt) as needed to enable our Analytics Engineering team translate raw data into business-ready datasets aligned to core metrics like ARR, CAC, and churn.
- Own pipeline reliability and observability - monitoring, automated failure alerting, and lineage tracking across both streaming and batch pipelines.
- Build the technical foundation for self-service and AI-powered reporting, partnering with BI, Product & Engineering stakeholders on recurring executive and departmental reports.
- Implement data governance practices, including documentation standards and access controls.
- Partner cross-functionally with Finance, Marketing, Customer Success, and Operations to translate data needs into reliable, low-latency data products.
- Leverage AI-augmented development workflows (e.g., Claude Code) to accelerate pipeline development and documentation.
Requirements- 7+ years of hands-on data engineering experience, with meaningful depth in streaming/event-driven systems, not just batch pipelines.
- Proven experience designing and building near real-time pipelines from scratch (e.g., Kafka, Kinesis, Flink, Debezium/CDC) in a production environment.
- Hands-on production experience with vector databases and embeddings (e.g., Zilliz, Pinecone, Weaviate, pgvector, Milvus) - ideally having built this infrastructure from the ground up rather than just consuming a managed AI feature.
- Advanced proficiency in SQL and Python.
- Working knowledge of a cloud warehouse/lakehouse platform (Snowflake, BigQuery, or Databricks) and dbt - you'll use these, but they're the storage/transform layer supporting the streaming and AI work, not the main focus.
- Proven experience building or materially contributing to an end-to-end production data environment, ideally as an early or founding data hire.
- Familiarity with B2B SaaS and recurring revenue data models (customer lifecycle, pipeline/conversion data).
- Working knowledge of BI/reporting tools (e.g., Looker, Tableau, Power BI) as a downstream consumer of your data models.
- Ability to work independently and drive multi-stakeholder projects in a lean, scrappy, fast-moving environment - comfortable with ambiguity and building without a lot of existing infrastructure or process.
Skills and Knowledge- Strong command of event streaming and CDC tooling.
- Hands-on experience with vector databases (Pinecone, Weaviate, pgvector, Milvus, or similar), including embedding strategies and chunking approaches for retrieval use cases.
- Working knowledge of ELT/ETL tools (e.g., Fivetran, Airbyte) for batch use cases.
- Working knowledge of data observability/reliability practices - automated alerting, lineage tracking.
- Fluency with AI-augmented development tools (e.g., Claude, Copilot) to accelerate engineering and documentation.
