Your Mission

  • Drive the development of data streaming across our event-based architecture, using technologies such as Kafka and Node.js

  • Be hands-on by writing and owning production code, setting a high quality bar through thoughtful PR reviews, debugging production issues, and continuously improving reliability, operability, and observability across data streaming pipelines
  • Act as a technical mentor to engineers across multiple teams on event-driven architecture, streaming patterns and anti-patterns, schema design and evolution, and data contracts and ownership
  • Influence the technical direction of the organization by collaborating with senior leadership, helping to establish well-designed and well-documented architectures, and bringing systems into production
  • Collaborate with cross-functional teams to define technical solutions for data streaming and data governance, aligning with business goals and stakeholder needs

Your Story

  • 5+ years of experience building and operating large scale event driven systems in production
  • Extensive hands-on experience with Apache Kafka in production, including modeling data pipelines and applying streaming patterns and anti-patterns
  • Experience leading complex technical initiatives, partnering with multiple stakeholders and teams, and providing technical direction to others
  • Experience mentoring and coaching engineers, providing guidance and feedback to support growth and development
  • Exceptional verbal and written communication skills, with the ability to clearly articulate complex technical concepts to senior leaders, technical stakeholders, and cross-functional teams
