Senior Engineer

Vantage is hiring a Senior Engineer. In this role you'll focus on building features and integrations with partner systems while acting as a subject matter expert and mentor for our engineering team. Expect heavy use of external APIs to pull data, as well as designing and delivering APIs that both receive data from and push data to external sources. You'll work with large datasets, perform hands-on coding, and keep our services reliable and fast.

In this role you'll be called on to support multiple product teams to uphold sound architecture, high code quality, and on-time delivery. You'll be a trusted go-to reviewer for SQL and Django ORM changes, set clear standards for database and service performance, and guide design and trade-off decisions that keep the platform scalable.
