Job Summary

Are you an Apache Cassandra committer who wants to operate at the highest level of technical and community influence?

This role connects deep upstream work - binding committer authority, CEP-level design, release stewardship - directly to production-scale outcomes in one of the largest enterprise Cassandra deployments in the world.

The successful applicant will become our second Apache Cassandra core committer, joining a team that already includes an established core committer as well as a committer on the Cassandra Drivers project.

You will work at both levels - upstream influence and customer impact - with meaningful autonomy, strong peer collaboration, and direct access to the product and field relationships that turn technical work into commercial outcomes. This is a globally distributed team with up to 10% travel. The role is based in one of our office locations - US

(San Jose, Raleigh, Boston, or Seattle),
requires 3 days per week in office.

Overview

As a Senior Open Source Software Engineer, your responsibilities will include:
• Lead end-to-end upstream initiatives in Apache Cassandra, from CEP authoring and design consensus through implementation, review, and release, in domains such as storage/compaction, indexing and SAI/vector, distributed repair,
observability, and Cassandra releases.
• Provide binding committer reviews on upstream patches and community contributions, applying the technical rigor and authority that moves high-quality work through the Apache Cassandra review process.
• Co-own Apache Cassandra core release management as part of the rotating committer pool and, where capacity allows, contribute to NetApp-led ecosystem releases (Cassandra Sidecar, Analytics, GoCQL).
• Translate enterprise customer needs into credible upstream proposals, CEP-level designs, and sustained technical engagement that only a committer can supply; advise product and field teams on complex upstream trade-offs.
• Shape community direction through evidence-based participation on the dev@ mailing list, Apache Jira, GitHub, and community forums; influence project
decisions on architecture, release policy, contribution standards, and long-term
roadmap.
• Mentor engineers toward committer standing and raise overall contribution quality through rigorous review practices, test discipline, and clear engineering guidance.
• Improve upstream infrastructure - CI reliability, test coverage, contributor tooling, and release automation - to reduce project-wide maintenance burden and strengthen NetApp's reputation as a steward of the project.

Job Requirements

• A minimum of 12 years of applicable professional software engineering experience is required.
• Current Apache Cassandra committer status with a sustained and publicly verifiable upstream track record across patches, reviews, and community standing
  in Cassandra core or a closely related subproject.
• Expert Java engineering capability in performance-sensitive, concurrent, and production-grade distributed systems - comfortable writing, reviewing, and
  reasoning about complex Cassandra internals at depth.
• Deep mastery of Apache Cassandra internals in at least one major domain: storage
  engine and compaction, indexing and SAI/vector, distributed consensus and repair
  (including Accord and CEP-37), observability and virtual tables, or release
  management and CI.
• Demonstrated ability to lead complex technical work through the Apache open source governance model: CEP authoring or co-sponsorship, design consensus,
  mailing-list engagement, and Jira-driven delivery from proposal through merge.
• Strong written communication for asynchronous, global, public technical collaboration - mailing lists, design documents, code reviews, and Jira threads.
• Proven senior-level technical judgment: resolves most blockers independently, determines approach on novel or ambiguous assignments, surfaces systemic risks
  proactively, and produces work that is consistent with project and team objectives.

Preferred qualifications

• PMC membership in Apache Cassandra or a related Apache subproject.
• Track record of work in Cassandra 6.0 feature areas (Accord, Transactional Cluster Metadata, CEP-37 automated repair, CEP-38 CQL Management API, ZSTD
  dictionary compression, SAI/vector write performance).
• Experience connecting upstream technical leadership to enterprise customer and operator outcomes - translating production pain points into accepted community
  improvements.
• History of mentoring contributors toward reviewer or committer standing in an open
  governance project.
• Familiarity with Cassandra ecosystem subprojects: Sidecar, Analytics (Spark bulk),
  GoCQL, or Apache Cassandra drivers.
