Principal Software Engineer

Marqeta is on a mission to change the way money moves. We’re one of the earliest enablers of embedded finance, a market opportunity sized up in the trillions. Our card issuing platform provides unprecedented flexibility and control for companies to issue cards, authorize transactions, and manage payment operations in real time.   Marqeta is powering the most well known brands in the new economy (Block, Cash App, Affirm, Instacart, Doordash, Uber, Walmart, etc). Today nearly 8 out of 10 Americans use a product powered by Marqeta every week. This is the opportunity of a lifetime to work with innovators around the world and unlock equitable financial access for all.

Reporting to the Director of Engineering and working with Fellows and product engineering teams, the Principal Software Engineer will be responsible for strengthening the foundation and scaling our Payment Processing system, which is  the most mission critical Core Platform for Marqeta.

As a Principal Engineer, you will help scale our Core Cardholder and Accounts Platform and technologies as our business continues to grow, while staying focused on shipping software that matters to our customers and their end consumers. You will innovate on various aspects of the platform used by our engineering organization to deliver high quality, highly scalable, and highly secure products to our customers.

We work Flexible First. This role can be performed remotely within the United States. We’d love for you to join us!

What you’ll do:

• Lead the architecture, design and implementation for major complex distributed systems.
• Be a subject matter expert (SME) regarding card payments, domain modeling and accounting (ledgering, settlement, recon etc.).
• Build the engineering design and the scaffolding that mid-level engineers can take and do the in-fill.
• Create simple elegant solutions that scale and reduce complexity, including removing code.  Your solutions keep human toil/support to a minimum.
• Lead from the front and own your system, including working with others.  You will make your system better while leveraging the rest of the team to help them learn and grow.
• Be the proven/demonstrable expert - people (from entry level engineers to business leaders) will go to you for your experience, credibility and approachability.  Your name will come up often because of your capabilities and impact.  At the same time, you will teach people to fish rather than fish for them.
• Articulately define an architecture including diagraming, while at the same time present/debate with a diverse audience.
• Manage your time and ensure you can delegate/provide opportunities for growth for others vs. get involved where you have to.

What we're looking for:

• 10+ years of engineering experience
• In-depth knowledge of card payments, double-entry bookkeeping and settlement systems and domain driven design.
• Deep understanding of payments ecosystem: merchants, acquirers, card networks and card issuers/processors.
• Demonstrated experience/problems solved in the Fintech space, preferably in card issuing and/or payment processing.  You understand the payments space, payments systems, and ISO 8583 messaging specifications.
• Demonstrated software development (Java) and operations experience with real time event based (payment) processing.
• We use Java throughout the business but welcome experience in different programming languages.
• Demonstrated ability to craft and deliver large complex projects
• Demonstrated experience with simplifying legacy code and migrating existing customers on new stacks.
• Demonstrated experience with databases and scaling transactional data stores.
• Demonstrated experience with deploying and maintaining distributed systems on AWS.
• Demonstrated passion to write code with great quality and test coverage.
• Demonstrated experience with Agile Scrum and TDD.
• Strong communication skills - including the ability to listen to the needs of others and comprehend complex matters, articulate issues in a clear and concise manner, and present effectively in both oral and written presentations to all levels in the organization.
• Team-oriented approach – can effectively lead a project or participate as an effective team member as well as work cross-functionally with other organizations.
