Summary
Help engineer the networking and communication layer behind large-scale AI training. You’ll optimize performance across distributed GPU clusters, investigate bottlenecks throughout the networking stack, and build tooling for benchmarking, profiling, and regression testing. The role combines systems performance, reliability, and close collaboration across infrastructure and hardware disciplines.
Highlights
Work on cutting-edge AI infrastructure and large-scale LLM training workloads. The role provides deep exposure to distributed GPU clusters, networking performance, benchmarking, profiling, reliability, and cross-functional collaboration with training, hardware, infrastructure, and networking specialists.
Description
About Verda
Verda is reimagining cloud infrastructure for AI workloads.
We are a full-stack AI cloud company, meaning we install, operate, and optimize our compute for training and inference of AI models.
Join Verda while it’s still being built - not once it’s finished!
Your responsibilities
In this role, you will focus on improving the networking and communication layer behind large-scale LLM training workloads.
You will optimize collective communication performance across distributed GPU clusters, helping improve throughput, utilization, and reliability for communication-bound workloads.
You will debug and analyze bottlenecks across the networking stack, building tooling and infrastructure for benchmarking, profiling, and regression testing of distributed training performance.
You will work closely with training, infrastructure, hardware, and networking teams to improve how workloads scale across clusters, contributing to both system reliability and overall training efficiency.
This role is highly collaborative and research-adjacent, requiring curiosity, initiative, and willingness to go deep into low-level communication systems and distributed training infrastructure.
Your key competencies
Experience with distributed systems, networking, or large-scale ML training infrastructureExperience with communication libraries such as NCCL, MPI, NVSHMEM, or similar technologiesExperience with profiling and debugging tools such as Nsight Systems, NCCL logs, PyTorch Profiler, or perfStrong systems thinking and ability to analyze performance bottlenecks across distributed environmentsSelf-starter mindset with ability to independently define and drive technical projectsStrong curiosity about low-level systems, networking, and large-scale AI infrastructure
Representative projects
Build tools to identify NCCL bottlenecks, slow ranks, and communication tail latencyBuild dashboards and regression infrastructure for training network health and performanceImplement fault-tolerance mechanisms to reduce cluster idle time and improve training efficiency
Practicalities
Location: Helsinki, Finland or London, UK
Hybrid mode: Working from either our Helsinki or London office for three days a week
Employment type: Full-time and permanent
