Block Senior Software Engineer at Block designing and building backend systems for data acquisition, processing, and access. This role leads projects and partners across teams to deliver reliable data platform capabilities.
Responsibilities
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 and contributing to Sessions, which brings customer activity data together for analytics and machine learning, among other high-priority initiatives. You will help shape technical direction, own projects from design through production, and build 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. A deep data engineering background is valuable, but it is not a prerequisite.
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.
Qualification
Deep experience designingTechnologies We Use and TeachKafka
Required
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. Experience building and operating low-latency streaming systems with Spark Structured Streaming is especially valuable.
You do not need prior experience with every technology in our stack.
