Senior Software Engineer (Data Platform, C++)

div class= content-intro p strong About Nebius: /strong /p p Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure. /p p Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI. /p p Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R amp;D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R amp;D. /p /div h4 id= The-role data-local-id= c41794725a88 data-renderer-start-pos= 1 The role /h4 p #LI-MM1 /p p data-renderer-start-pos= 11 data-local-id= b628b6030a86 We’re looking for a strong data-renderer-mark= true Software Engineer with strong C++ expertise /strong to join the team building and operating strong data-renderer-mark= true Nebius Data Platform /strong — a distributed storage and a processing platform that acts as the company’s “source of truth” and the backbone of many internal (and some external) products. /p p data-renderer-start-pos= 292 data-local-id= de1e1b789ce4 Nebius Data Platform is a strong data-renderer-mark= true single multi-tenant ecosystem based on YTsaurus /strong — instead of running separate HDFS/Kafka/HBase-style systems, we provide storage, compute, and analytics capabilities inside one platform. /p p data-renderer-start-pos= 506 data-local-id= bcbb3787b5d5 Built on top of the open-source YTsaurus ecosystem, we run and extend our own Nebius distribution and develop significant in-house functionality (core and platform-level). We can design, implement, and roll out features end-to-end on our clusters without waiting for upstream approvals and contribute upstream when it makes sense. /p p data-renderer-start-pos= 838 data-local-id= 7544511b100f At scale today, this includes strong data-renderer-mark= true ~500 servers, ~20k CPU cores /strong and nbsp; strong data-renderer-mark= true ~10 PB of compressed /strong strong data-renderer-mark= true data /strong in our largest production cluster, supporting workloads ranging from business-critical pipelines and financial transactions to large-scale ML/LLM training datasets and compute. /p h4 id= What’s-inside-the-platform data-local-id= 2100fd8e190a data-renderer-start-pos= 1105 What’s inside the platform /h4 p data-renderer-start-pos= 1133 data-local-id= 76f8ed17de21 You’ll work on a system that includes (and ties together): /p ul li data-renderer-start-pos= 1195 data-local-id= 6ddeb26cab43 strong data-renderer-mark= true Distributed Storage (Cypress) /strong : transactional semantics, tiered storage, erasure coding, replication, and strong reliability expectations. /li li data-renderer-start-pos= 1336 data-local-id= 13562646bfb3 strong data-renderer-mark= true Compute amp; ETL /strong : a cluster-wide job scheduler (tens of thousands of cores), MapReduce, strong data-renderer-mark= true YQL /strong for SQL-like data processing, and strong data-renderer-mark= true SPYT (Spark over YTsaurus) /strong for modern data engineering. /li li data-renderer-start-pos= 1518 data-local-id= 97897e1cbf8b strong data-renderer-mark= true Interactive analytics (CHYT) /strong : ClickHouse® instances spun up directly on compute nodes for fast SQL over data in-place. /li li data-renderer-start-pos= 1640 data-local-id= 02d7848ef2e9 strong data-renderer-mark= true Dynamic Tables /strong : low-latency NoSQL KV with distributed ACID transactions for OLTP-style workloads and feature stores. /li li data-renderer-start-pos= 1760 data-local-id= bcaf763a8a8a strong data-renderer-mark= true Orchestracto /strong : workflow orchestration deeply integrated with the platform (Airflow-like, but platform-native). /li /ul h4 id= What-you’ll-do data-local-id= ef3970644491 data-renderer-start-pos= 1873 What you’ll do /h4 p data-renderer-start-pos= 1889 data-local-id= 76f1e15bff02 We’re looking for engineers who combine strong systems skills with strong data-renderer-mark= true product sense /strong : understanding who uses the platform, why certain capabilities matter, and making pragmatic trade-offs to maximize impact.
