Senior Data Engineer

This is a 3‑month fixed‑term salaried contract located in Ontario, Canada, preferably in Toronto.

What you’ll do

- Pull data from Databricks, transform it, and load it into multiple graph database candidates — then tear them down and repeat under controlled, repeatable conditions.
- Build and manage relationship structures and entity linkages within each graph database to mirror real production data models.
- Implement benchmark queries in each technology’s native language (Cypher, GSQL, nGQL, AQL, openCypher) and as PostgreSQL recursive CTEs for the baseline.
- Build APIs against each candidate to evaluate real‑world query performance across use cases.
- Contribute scored candidate evaluations and written analysis to a final technology recommendation presented to engineering and architecture leadership.

What you bring

- Databricks fluency.
- Hands‑on experience with at least two graph databases — Neo4j and/or TigerGraph strongly preferred — and working proficiency in Cypher at minimum.
- Robust PostgreSQL skills: recursive CTEs, materialised views, query plan analysis, index strategy.
- Comfort spinning up and tearing down database environments repeatedly in a structured evaluation context.




- Experience designing and executing structured technology benchmarks at enterprise scale.
- Bonus: KYC/AML domain knowledge, Kubernetes for database workloads, or AWS‑native database deployment.

The anticipated hourly range for this position is $90, based on relevant experience, expertise, and organisational impact.
