Original job description

As Marqeta's Staff Software Engineer on the Core Edge Processing team, you will write and review production code at the heart of our processing systems, drive the initiatives that make them faster and more reliable, and help set the engineering bar for a team running real-time, always-on payment infrastructure. Core Edge Processing owns the systems that route and authorize transactions across card networks, along with the cryptographic infrastructure underneath them. This is a hands-on role where the quality of your code directly shapes whether transactions succeed.

We work Flexible First. This role can be performed remotely anywhere within the province where you reside, whether that's Ontario or British Columbia, Canada. We'd love for you to join us!

The Impact You'll Have

Ship and refine production code across our routing and processing stack, where every millisecond and every line counts
Lead initiatives that make our platform more reliable, faster, and more cost-efficient
Shape system design alongside your EM and fellow engineers, from data model changes to failure and degradation strategy to blast-radius containment
Take on complex, mission-critical codebases and lift the engineering standard for everyone around you
Mentor engineers and guide technical direction at the Staff level

Who You Are

An engineer with 8+ years of experience who is still deep in the code every day
A Java expert with strong fundamentals in concurrency, performance, and building reliable systems at scale
Someone who writes system designs, defends them in review, and runs what you build in production
At home in a regulated, cloud-native, high-availability environment
Experienced in payment processing, card issuing, or network integration (JPOS, ISO 8583, or similar)

Nice-To-Haves

Cryptography or key management experience (HSM, AWS Payment Cryptography, KMS)
Experience running systems across multiple regions, including tested failover
Hands-on experience with Kubernetes and AWS
