[Hiring] Senior Software Engineer @Block

Role Description

The Data Enablement team builds the platforms and frameworks that move and serve data across Block. We support four core capabilities—online and offline data projections, third-party data integration, and graph data stores—for customers across the company, including Risk, Compliance, Data Engineering, and Data Science.

As a Senior Software Engineer on the team, you will design, build, and operate backend systems that make data easier to acquire, process, and use. Your work will include:

• Expanding Block’s external data acquisition capabilities.
• Contributing to Sessions, which brings customer activity data together for analytics and machine learning.
• Shaping technical direction and owning projects from design through production.
• Building shared capabilities that other teams can use.

We’re looking for a strong systems engineer who brings sound architectural judgment, takes ownership of outcomes, and is eager to learn across the backend and data engineering worlds.

You Will

• Design and build shared backend services, platforms, and frameworks that support data acquisition, processing, and access across Block.
• Lead projects from problem definition and architecture through implementation, rollout, and ongoing production operation.
• Work across backend services, event-driven systems, and batch and streaming data processing to deliver reliable capabilities for downstream consumers.
• Partner with software engineers on the team and across the organization, Data Foundations engineers, and data scientists to turn their needs into reusable platform capabilities.
• Make practical architectural decisions that balance reliability, latency, scalability, cost, and maintainability.
• Improve the observability, data quality, and operational reliability of the systems you build and support.
• Mentor engineers, contribute to technical standards, and grow familiar with the team’s other domains over time.

Qualifications

• 8+ years of professional software engineering experience, or equivalent experience.
• Deep experience designing, building, and operating distributed backend systems in production.
• A track record of leading technical projects, making sound architectural decisions, and turning ambiguous problems into well-defined, deliverable work.
• Proficiency in a backend programming language such as Java or Kotlin, with strong software design and engineering fundamentals.
• Experience building on cloud infrastructure, ideally AWS.
• The ability to learn unfamiliar systems and domains, communicate technical trade-offs clearly, and collaborate across software engineering, data engineering, and data science.
• Bonus points for a data engineering background, including data pipelines, large-scale processing, or lakehouse and warehouse systems.
• Bonus points for hands-on experience with Kafka and Spark Structured Streaming.
