Remote Databricks Developer Jobs in Chicago, IL (NOW HIRING)

Location: Remote US
Start date: ASAP
Languages: English (required)

About the Role

Pragmatike is hiring on behalf of a fast-growing AI startup recognized as a Top 10 GenAI company by GTM Capital, founded by MIT CSAIL researchers.

We are searching for a CUDA Kernel Engineer who has hands-on experience developing and optimizing NVIDIA CUDA kernels from scratch. You will work on the GPU performance layer powering large-scale, high-throughput AI systems used by Fortune 500 customers.

This role is ideal for someone who deeply understands NVIDIA GPU architecture, memory hierarchy, warp-level execution, and profiling workflowsnot someone coming from generic hardware, FPGA, or non-NVIDIA compute backgrounds. You will directly influence the GPU efficiency, throughput, and scalability of mission-critical AI systems.

What Youll Do

• Design, implement, and optimize custom CUDA kernels for NVIDIA GPUs, with a focus on maximizing occupancy, memory throughput, and warp efficiency.
• Profile GPU workloads using tools such as Nsight Compute, Nsight Systems, nvprof, and CUDA‐MEMCHECK.
• Analyze and eliminate performance bottlenecks including warp divergence, uncoalesced memory access, register pressure, and PCIe transfer overhead.
• Improve GPU memory pipelines (global, shared, L2, texture memory) and ensure proper memory coalescing.
• Collaborate closely with AI systems, model acceleration, and backend distributed systems teams.
• Contribute to GPU architecture decisions, kernel libraries, and internal performance-engineering best practices.

What Were Looking For

• Proven track record building NVIDIA CUDA kernels from scratchnot just calling existing libraries.
• Strong ability to optimize kernels (tiling strategies, occupancy tuning, shared memory design, warp scheduling).
• Deep understanding of CUDA threads, warps, blocks, and grids, GPU memory hierarchy and memory coalescing, as well as warp divergence (how to detect, analyze, and mitigate it)
• Experience diagnosing PCIe bottlenecks and optimizing host-device transfers (pinned memory, streams, batching, overlap).
• Familiarity with C++, CUDA runtime APIs, and GPU debugging/profiling tooling.

Bonus Points

• Experience with multi-GPU or distributed GPU systems (NCCL, NVLink, MIG).
• Background in GPU acceleration for ML frameworks or HPC workloads.
• Knowledge of model inference optimization (TensorRT, CUDA Graphs, CUTLASS).
• Exposure to compiler-level optimization or PTX/SASS analysis.
• Startup experience or comfort working in fast-moving, ambiguous environments.

Why This Role Will Pivot Your Career

• Research pedigree: MIT CSAIL founders recognized for breakthrough AI and systems contributions.
• Customer impact: Deploy AI solutions powering Fortune 500 clients.
• Industry momentum: Lab alumni have led high-value acquisitions (MosaicML Databricks, Run:AI Nvidia, W&B CoreWeave).
• Funding & growth: Oversubscribed seed round, next funding in 2026.
• Career growth & influence: Lead AI initiatives, optimize pipelines, and directly impact production AI systems at scale.
• Culture & autonomy: Own critical systems while collaborating with world-class engineers.
• Aspirational impact: Solve GPU/AI performance challenges few engineers ever face.

Benefits

• Competitive salary & equity options
• Sign-on bonus
• Health, Dental, and Vision
• 401k
