At CelerData, we empower organizations to unlock the full potential of their data with our next-generation, cloud-native, high-performance analytical database built for modern lakehouse architecture. Challenging the status quo set by products like Snowflake, ClickHouse, and Trino, we’re driving the future of data analytics by delivering unparalleled query performance and a streamlined architecture for enterprises worldwide. Join us to help customers transform their data into actionable insights and achieve exceptional technical success.
Job Overview
We are expanding our engineering team and hiring Software Engineers across multiple levels (Junior, Mid, Senior). You’ll contribute to StarRocks, our high-performance SQL engine for composable lakehouses, alongside experienced engineers and open-source contributors. If you love systems programming, care about performance while taking on real impact, we’d love to talk.
What You’ll Do
Implement features and fixes in StarRocks under guidance, from design review to production rollout.
Write robust, maintainable code and unit/integration tests for performance-critical paths.
Profile and debug issues related to concurrency, memory, IO, and query execution.
Participate in code reviews, pairing, and design discussions to level up quickly.
Collaborate with our open-source community: reproduce issues, review small PRs, and improve docs.
Learn (and apply) fundamentals of fault tolerance, high availability, and scalability in distributed systems.
For Junior Candidates:
What You’ll Bring
Bachelor’s degree in Computer Science or a related field or equivalent practical experience.
Solid CS fundamentals: data structures, algorithms, operating systems, networking basics, and databases/SQL concepts.
Proficiency in C++ (required); proficiency in Java is a plus.
Comfort with Linux, Git, and writing tests; ability to read technical docs and RFCs.
Curiosity, ownership, and a growth mindset - comfortable asking questions and iterating on feedback.
Nice to Have (Not Required)
Exposure to distributed systems concepts (consensus, replication, transactions).
Familiarity with StarRocks or similar tech: Apache Iceberg, Parquet, Spark, Trino, ClickHouse, or vectorized execution.
Experience with performance tools (e.g., perf, gdb, flame graphs) or observability (logs/metrics/tracing).
Contributions to any open-source project (even small PRs/issues) or systems-level class projects.
Scripting experience (Python/Go/Bash) for tooling and automation.
How We Support Your Growth
Mentorship from senior engineers and regular 1:1s.
Clear learning path and meaningful starter projects.
Code reviews focused on teaching, not just gating.
Opportunities to engage with and contribute to open source.
For Senior Candidates:
What You’ll Bring
At least 3 years of professional experience in developing commercial or open-source software applications.
Bachelor’s degree in Computer Science or related fields is required (Master’s preferred).
Advanced proficiency in C++ and Java, with a proven track record in designing and implementing complex functionalities in performance-critical environments.
Experience with large-scale distributed systems, including transaction management and consistency models.
Evidence of active participation in open-source projects or a deep understanding of technologies such as StarRocks, Apache Iceberg, Parquet, Spark, Trino, or similar big data solutions.
This position is hybrid in Menlo Park, CA.
