Senior Data Engineer

Aeolus Data Solutions is a boutique, founder-led data engineering practice for startups andscale-ups across North America. We design, build, and audit the production data pipelines andAI-ready data foundations that analytics and AI initiatives actually run on. Our thesis is simple:AI projects don’t fail on the model — they fail on the data pipeline underneath it.

We bring Big Tech engineering discipline (CI/CD, automated testing, infrastructure-as-code, and versioned pipelines) to companies too lean to hire it in-house, and a senior practitioner worksdirectly with every client. No account managers. No junior delivery bench. No handoffs.

The role

You’ll be the senior engineer on client engagements from first audit to production handoff.That means going deep on an unfamiliar stack in week one, finding the schema drift and silentpipeline failures nobody caught, and then building the foundation that holds. One month you’rehardening a RAG ingestion pipeline; the next you’re rebuilding a scale-up’s warehouse orembedding as their fractional data lead. You own the work and the client relationship directly —this is a senior seat, not a ticket queue.

What you’ll do

• Run data & AI-readiness audits. Assess a client’s pipelines, schemas, metadata, andwarehouse; write the technical report and the prioritized remediation roadmap that follows. • Build production data platforms. ELT/ETL pipelines, dbt models and tests, orchestration(Airflow/Dagster), warehouse and lakehouse builds…
