Role Description Marqeta is looking for a talented Senior Software Engineer to independently identify and deliver software solutions on our Data Infrastructure team through a set of milestones spanning a specific platform focus or a multi-component system. You will own and deliver projects in service of quarterly goals on the team and independently identify solutions to solve ambiguous, open-ended problems. You will work in collaboration with your team and cross-functional partners. The Data Infrastructure team, within our Data & ML Platforms organization, is responsible for the data lakehouse, streaming, orchestration, and catalog platforms that power analytics and AI across Marqeta. We're a platform engineering team building infrastructure that other engineering teams depend on. At Marqeta, participation in a rotational on-call pager duty is a required part of the software engineering role. The specifics of the rotation may vary by team, depending on team size and structure, and will be discussed further during the interview process. We work Flexible First. This role can be performed remotely anywhere within Ontario or British Columbia, Canada. We’d love for you to join us! The Impact You'll Have - Define and deliver well-scoped milestones for projects, and may be a technical lead for projects on your team. - Lead design for small-to-medium components and participate in design for larger components, moving from task-level impact to small-to-medium project-level impact. - Have significant ownership of a component of the data infrastructure, including its reliability, performance, and developer experience. - Identify gaps and propose plans towards addressing those gaps. - Independently write code that is clear, well-tested, and appropriately flexible, reusable, and adaptable to changing requirements. - Actively level up less-experienced members of your team by helping them with their craft, providing guidance, and setting a good example. - Participate in on-call coverage. Qualifications - 5+ years of experience as a software engineer with a Bachelor's degree; or 3 years of experience with an advanced degree. In lieu of a degree, 8+ years of relevant experience may suffice. - Strong proficiency in Python in a production context. - Proficiency with SQL. - Experience working with distributed systems. - Production experience with multiple core data technologies, including Apache Kafka, Apache Spark, and Apache Airflow (or close equivalents). - Production experience with modern table formats (Parquet, Hudi, Iceberg, or Delta Lake). - Production experience with AWS or another major cloud. - Experience with infrastructure-as-code (Terraform, CloudFormation, CDK, or equivalent). - Experience monitoring and alerting on production systems. - Ability to decompose business problems into solutions that may require designs with multiple interacting components. - Ability to build correct, maintainable software components. - Ability to work with cross-functional stakeholders to identify technical blindspots and clarify ambiguity. - Ability to present clear and concise messages tailored to various audiences; able to communicate clearly and respectfully both verbally and in writing. - A focus on quality and meeting deadlines.
