Trainium (NKI) Kernel Expert
Company: Mercor · Pay: $70–$90/hr · Location: Remote — Global · Type: contractor · Posted: 2026-09-14
The Hardware Revolution in AI: Why NKI and AWS Trainium Expertise Are in Massive Demand
The explosive growth of large language models and frontier artificial intelligence has pushed computational hardware to its absolute limits. While traditional GPU infrastructures have dominated the early waves of machine learning development, tech giants and leading AI labs are aggressively diversifying their hardware pipelines. AWS Trainium and Inferentia architectures, paired with specialized low-level programming frameworks like the Neuron Kernel Interface (NKI), represent the bleeding edge of high-performance, cost-effective AI model training and inference.
However, developing, migrating, and optimizing kernels for custom accelerators requires a rare breed of systems engineering talent. Traditional software developers and even standard GPU kernel engineers often face steep learning curves when transitioning to tile-based architectures and specialized memory hierarchies. To bridge this gap, top-tier AI labs are turning to elite remote consultants to audit, refine, and grade automated and human-written development tasks. Positions like the Trainium (NKI) Kernel Expert role on Mercor offer specialized systems engineers an incredible opportunity to earn $70 to $90 per hour on flexible, high-impact contracts.
Detailed Job Overview & Core Responsibilities
For systems engineers, machine learning infrastructure architects, and GPU/TPU optimization specialists looking for lucrative remote opportunities, this role offers a chance to directly influence how frontier AI models utilize custom silicon hardware. The core objective is to evaluate code quality, execution correctness, and hardware alignment for advanced NKI development tasks.
Key Responsibilities & Evaluation Scope:
- Task Quality Assessment: Evaluate the quality, execution correctness, and hardware-appropriateness of Neuron Kernel Interface (NKI) development tasks used to train and refine frontier AI lab models.
- CUDA-to-NKI Migration Auditing: Assess the fidelity, efficiency, and semantic accuracy of code migrating from traditional CUDA environments to AWS Trainium architectures.
- Performance Optimization Analysis: Review Trainium-specific performance optimization practices, ensuring maximal efficiency across underlying hardware layers.
- Numerical Correctness Standards: Validate cross-platform numerical correctness standards, addressing disparities in GPU versus Trainium accumulation orders, rounding behaviors, and mixed-precision semantics.
- Rubric-Based Feedback: Deliver clear, structured, and technically rigorous written feedback to align AI training datasets and model generation outputs with enterprise standards.
Candidate Qualifications: Basic and Preferred Requirements
Given the highly specialized nature of custom silicon accelerators and low-level kernel compilation, the qualification criteria are tailored for experienced systems professionals.
- Hands-On NKI Experience: 2+ years of professional, hands-on experience developing or optimizing kernels using the Neuron Kernel Interface (NKI) targeting AWS Trainium/Inferentia2 hardware.
- Architectural Mastery: Strong understanding of NKI-specific development patterns, including tile-based computation, SBUF/PSUM/HBM memory-hierarchy management, partition-dimension constraints, and DMA orchestration.
- Migration Assessment: Demonstrated professional experience assessing CUDA-to-NKI migration quality and execution fidelity.
- Profiling Competency: Familiarity with Trainium-specific performance profiling, such as NeuronCore pipeline utilization, tensor-engine throughput, and identifying memory-bandwidth bottlenecks.
- Numerical Semantics: Proven experience defining or evaluating cross-platform numerical-correctness standards.
Preferred Qualifications: Direct experience with the AWS Neuron SDK, Neuron Compiler internals, or direct contributions to NKI kernel libraries; prior CUDA or Triton kernel development; familiarity with Trainium hardware specifications (NeuronCore-v2 architecture, on-chip SRAM topology, supported data types like FP32/BF16/FP8/INT8); and experience benchmarking ML training workloads on Trn1/Trn2 instances.
Contract Terms, Remote Autonomy, and Global Payouts
Contracting through Mercor provides elite technical professionals with the freedom to command top-tier compensation without sacrificing lifestyle flexibility or schedule autonomy:
- Independent Contractor Freedom: Complete your evaluation assignments entirely on your own schedule from anywhere within the United States (note: H1-B or STEM OPT support is currently unavailable).
- Flexible Project Lifecycles: Projects adapt dynamically to the rapidly shifting R&D schedules of frontier AI labs, allowing you to scale your contract engagement according to your availability.
- Prompt Weekly Compensation: Enjoy dependable weekly payouts processed through secure global payment rails such as Stripe and Wise.
Why Hardware and Systems Experts Choose AI Training Roles
In traditional engineering roles, career growth often locks professionals into rigid organizational structures, endless administrative meetings, and stagnant compensation brackets. Conversely, specialized consulting contracts in AI infrastructure allow you to focus purely on complex technical problem-solving. By auditing cutting-edge NKI kernels, you stay at the forefront of cloud computing hardware evolution while earning an impressive $70 to $90 per hour.
Furthermore, collaborating with the engineering teams powering next-generation AI models sharpens your competitive edge in cloud architecture, compiler design, and heterogeneous computing.
