The Role

We're building the AI Assistant for commercial bankers. Relationship managers, treasury and credit teams use it to understand their business customers and act faster, and you'll be right in the middle of building it.

This is a hands-on job for people who like building and want to stay as an individual contributor. You'll design and ship the things the assistant depends on, and they'll still be yours once they're live. You'll also get a real say in where it goes next. That means making your case to engineers, product and the commercial team, and bringing them along with you.

What You'll Work On

• The pipelines the assistant draws on, from raw source data to the numbers it quotes. You'll build them and keep them running.

• The layers on top: metrics, definitions and the relationships between them, so a pile of financial data becomes something the assistant can reason over.

• Testing and observability. We want what we ship to get more reliable, and we want the people around you to get better at it too.

You'll Probably Have

• Built pipelines and production systems from scratch, writing the code yourself rather than mostly configuring managed services. If we ask about the hardest logic you've written, you'll have a story ready.

• Good Python habits. Your tests are the kind someone else would be glad to inherit.

• Real depth in a few of SQL, Spark, Databricks/Delta Lake, Dagster/Airflow/Temporal and dbt, and opinions about which ones annoyed you.

• Time with CI/CD, Docker and cloud infrastructure. Even better if you set them up for a team.

• An interest in the business behind the data. If the data says the request is wrong, you'll say so.

• AI already built into how you work. You can show us where it saved you real time, or got you up to speed on something new.

• Nice to have: some experience getting data ready for LLMs, like semantic layers, text-to-SQL or retrieval.

How We Work

We're a small team with plenty to do. Things move fast: we'd rather ship something useful and improve it than polish it in private. What you build is yours from start to finish.

There’s no return-to-office mandate, and you can work hybrid or fully remote. We trust you to be around when the team needs you and to deliver what you said you would. What we don’t want is anyone staying online late to prove a point.
