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.
NetApp Instaclustr runs one of the industry's largest Cassandra managed services, spanning a broad range of enterprise customers across financial services, retail, and technology sectors. Our Cassandra engineering team leads active work on Cassandra 6.0, owns releases across core and ecosystem subprojects, and drives upstream contributions that directly address production-scale operator needs.
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
Note that we have global opportunities as well in Cork,Ireland & Netherlands (Schiphol).
(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.
Education
Bachelor's degree in engineering or technical related field of study Or additional equivalent experience.

Data privacy
We care about your privacy and, therefore, ask that you read our Candidate Privacy Notice before you submit any personal information to us.
NetApp does not carry out any solely automated decision making (i.e. the process of making a decision by automated means without any human involvement) in determining your suitability or eligibility for specific roles.
However, the processing of your personal information is carried out with the aid of manual and automated tools. In particular, NetApp may use an automated employment evaluation tool or similar tool as one of several tools, actions, and/or steps to assist with NetApp’s review of candidate applications for various hiring needs. Currently, when addressing certain hiring needs, NetApp uses the Eightfold tool which can provide an initial ranking of a candidate’s skills and experience, based on information provided by the applicant in the application and/or supporting documentation, in comparison to the NetApp designated key requirements of a specific role. Additionally, the tool may be used to help review and/or rank internal employees seeking promotion or other internal mobility. However, our talent acquisition team or our recruiters will ultimately select the candidates for further consideration, following human review of any automated evaluation results and associated underlying documentation (or lack thereof) submitted with the candidates’ application.
An independent audit of the Eightfold Matching Model tool can be found at https://eightfold.ai/nyc-eightfoldmatching-model.
Candidates may request an alternative selection process which will not be subject to the Eightfold matching tool or to any electronic automated employment evaluation by contacting NetApp at careers@netapp.com. To bypass the Eightfold matching tool or any electronic automated employment evaluation, you must include a resume and job ID with your email to careers@netapp.com and you must include in the subject line of your email: Data Privacy Request. Candidates who have questions or want to request additional information on the source of data, type of data, and/or collection of data related to the candidate review process should contact NetApp at careers@netapp.com
Note: Eightfold is not applicable to temporary hiring opportunities. If you are interested in temporary roles, you can apply via a third-party site managed by our preferred supplier, Magnit Global. Magnit Global will provide its own privacy disclosures for your review as part of the application process.
