About this job
SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
SR. SOFTWARE ENGINEER, DATA PLATFORM
The Data Platform team builds and operates the infrastructure responsible for all large-scale data transport and processing across the company. We own and manage core systems including Apache Kafka, HDFS, Spark, Flink, and Trino, enabling real-time ML pipelines, feed ranking, experimentation, analytics, and observability at petabyte scale. Our team deals with latency-critical workloads, high-throughput streaming, and distributed compute systems that require fault tolerance, performance, and absolute reliability.
As a software engineer on the Data Platform team, you will design, build, and operate the distributed systems powering SpaceXSI's data movement and compute. You will take ownership of infrastructure components that process trillions of events daily, driving the scalability, performance, and reliability of the systems that power product and ML workloads across the company.
RESPONSIBILITIES:
- Design and implement high-throughput, low-latency data ingestion and transport systems
- Scale and optimize multi-tenant Kafka infrastructure supporting real-time workloads
- Extend and tune Spark, Flink, and Trino for demanding production pipelines
- Build interfaces, APIs, and pipelines enabling teams to query, process, and move data at petabyte scale
- Debug and optimize distributed systems, with a focus on reliability and performance under load
- Collaborate with ML, product, and infrastructure teams to unblock critical data workflows
BASIC QUALIFICATIONS:
- Bachelor’s degree in computer science, engineering, math, or technical discipline; OR 5+ years of professional software development experience in lieu of a degree
- Experience with Kafka, Flink, Spark, Trino, or Hadoop in production
PREFERRED SKILLS AND EXPERIENCE:
- Proficiency in Rust, Go, Scala or similar systems languages
- Proven expertise in distributed systems, stream processing, or large-scale data platforms
- Strong debugging, profiling, and performance optimization skills
- Track record of shipping and maintaining critical infrastructure
- Comfortable working in fast-moving, high-stakes environments with minimal guardrails
COMPENSATION AND BENEFITS:
$180,000 - $330,000 USD
Base salary is just one part of our total rewards package at SpaceXSI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.
