We’re looking for a Data Engineer who can own the journey of data from source systems to decision-ready outputs. You’ll build and maintain pipelines, model data, stand up dashboards, and integrate systems via APIs. In a team this size, you’ll also get involved in application development - building internal tools with Streamlit, FastAPI, or HTMX that put data directly in the hands of our investment and asset management teams.
In your first 3 months you’ll have taken ownership of at least one critical pipeline from an external system into Databricks, and built or materially improved a reporting layer used by Fund Management or Asset Management.
Design, build, and maintain scalable data pipelines in Databricks, ensuring data is reliable, timely, and well-documented.
Own and evolve our Databricks models - define schemas, enforce testing, and keep the warehouse clean.
Automate manual data processes using Python, replacing spreadsheets and ad-hoc workflows with robust, repeatable jobs.
Build performance dashboards and reports in Streamlit and HTMX (FastAPI) that Finance, Asset Management, and Fund Management actually use.
Integrate internal and third-party systems via REST APIs, improving data accessibility across the business.
Champion data quality - implement validation, monitoring, and governance practices that give stakeholders confidence in the numbers.
Collaborate directly with non-technical teams to understand their problems and translate them into data solutions.
Strong SQL and Python skills, used daily for pipeline development, data modelling, and automation.
Experience with modern data stack tooling: a cloud data platform (Databricks preferred), and version control (Git/GitHub).
A solid understanding of data modelling, warehousing patterns, and ETL/ELT design.
To be comfortable working with Postgres or similar relational databases.
Clear communication - you can explain a data model to a fund manager and discuss trade-offs with an engineer.
A bias toward shipping: you’d rather get something working and iterate than spend weeks in design.
Full-stack development experience - particularly with Streamlit, FastAPI, or HTMX.
Experience building and managing REST APIs, including authentication, rate limiting, and documentation.
Familiarity with renewable energy, infrastructure investment, or financial services data.
Experience evaluating and adopting AI/ML tooling to augment engineering workflows.
