We are building a commercial insights platform that our field, brand, medical and market access teams will use to make decisions at launch and for years afterward.

You would be the first engineering hire on it. You will make the architectural decisions, stand up the infrastructure, build the backend and the services, and own how the whole thing is deployed, secured and released.

You will then own it in production. This role builds the platform and then maintains, runs and extends it as the business grows into it. It is a permanent position on a system with a long life ahead of it, not a fixed-term project that ends at a launch date. The commercial organization has other data and software needs beyond this platform, so the work is likely to broaden over time rather than narrow.

You will work directly with the Director of Commercial Data Science, who owns the AI layer and the governed business definitions, alongside a Senior Data Scientist who builds the analytics and a Design Engineer who owns the interface layer.
You own everything required to turn that work into software people can open and rely on.

Very few roles offer this much architectural ownership with this much of the hard analytical thinking already done, on something the leadership of the company is actively watching rather than something buried three layers down.

• Make the foundational architecture decisions and be accountable for them: hosting shape, application framework, how the application reads from our Databricks warehouse, authentication and authorization, environments, release process.
• Deliver the first vertical slice early. One real measure taken end to end into production: warehouse to API to authenticated web page to rendered chart, deployed, logged, access-controlled. Every part of the platform after it reuses that path.
• Build the backend services that expose governed data and generated summaries to the interface layer.
• Own the cloud environment. Provision it, secure it, monitor it, and be able to explain and…
