Senior Staff Software Engineer – Data Platform

Key Highlights

• Yes: writing production code on the platform’s hardest problems, owning the design and build of new abstractions end-to-end, leading design reviews, setting the engineering bar through the work itself.
• Sometimes: prototyping, deep diving on a tricky migration, pairing with engineers on tough problems.
• Modernization. Building out the lakehouse — the patterns Marqeta will run on for years. New abstractions, new tooling, the paved road internal teams want to use.
• Live system work. Evolving and hardening the platform that’s already in production. Reliability, performance, developer experience — improved without disrupting the teams who depend on it.
• Engineering excellence. Testing confidence, release velocity. On call, blameless postmortems.
