Your role and responsibilities


The Stream Processing & Analytics (SPA) team is building an elastic, reliable, durable, cost-effective, and performant stream processing engine based on Apache Flink for Confluent Cloud. Within SPA, the Flink Autopilot team owns the systems that make Flink a true cloud-native, "zero-knob" experience — autoscaling, resource management, and worry-free operations that deliver the right amount of stream processing at any given moment, so customers can focus on their use case instead of managing infrastructure.

As a senior engineer on Autopilot, you'll independently drive complex engineering projects end to end within our domain, become a go-to expert for one or more areas of the system, and help the team raise the quality and operational health of the platform.

What You Will Do

  • Drive complex projects end to end: Independently take projects from design through production within the Autopilot domain — for example, autoscaling logic, resource management, or job/task manager resilience. Break large efforts into clear milestones and deliver them with high quality
  • Master a domain: Develop deep expertise in one or more areas of Autopilot and become the person the team relies on for that area, representing your components in cross-functional design and architecture discussions
  • Write scalable, performant systems: Design and build highly scalable, fault-tolerant systems, and articulate your thinking through clear design documents, one-pagers, and proposals
  • Operational excellence and on-call: Improve the stability, performance, and automation of the systems you own. Participate in the on-call rotation, drive and mitigate incidents, and proactively address recurring operational toil
  • Raise the bar through reviews and mentorship: Review PRs and designs with constructive feedback, coach junior engineers and interns, and contribute to the team's interview question pool and hiring
  • Communicate clearly: Demonstrate strong, succinct written and verbal communication to align a small group on technical direction and keep stakeholders informed

IBM’s AI and data platform scales and accelerates the impact of AI with trusted data, and provides leading capabilities to train, tune and deploy AI across business.
