Senior Staff Software Engineer (Data Platform)
Company: Marqeta
Location: Toronto, Canada
Type: Full-time
Posted: 2026-06-07
About this role
- The lakehouse and the streaming ingestion that feeds it
- Iceberg/Delta on S3, Spark/Glue processing, Kafka and CDC pipelines, the abstractions that let other teams land data, build pipelines, and publish datasets without inventing the patterns themselves
- You’d help set the multi-year technical direction, design the golden paths, and ship the work — directly, with your hands on the code that matters
- You’d report to the Director of Data Engineering and partner with a peer Manager whose scope is people leadership and operational delivery
- You own technical direction, application architecture, and the engineering bar
- You’ll work alongside other senior staff engineers across the broader data platform org, and partner with security, compliance, and the consumer teams who depend on what we ship
- What “hands-on” actually means here
- Worth being specific, because “hands-on” means different things to different people:
- 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
