Artificial Intelligence Specialist

Senior / Staff AI/ML Engineer – Model Development. Austin, Texas | Full-Time | On-Site - moving to HybridThe strongest AI engineers are rarely looking for another job. They are usually looking for a technical problem worth owning.Stelvio is supporting an Austin-based company seeking Principal/Staff-level AI/ML Engineers to take significant ownership of its core model-development work.This is a highly autonomous individual-contributor position for someone who wants to build - not simply integrate - AI technology.Working closely with the founders and technical leadership team, you will be trusted to identify the right technical approach, design experiments and take models from early development through optimization and production deployment.You will be responsible for areas including:Designing and training specialist machine-learning modelsBuilding models from the ground up where the problem requires itFine-tuning and post-training foundation models using proprietary datasetsOwning experimentation, evaluation, benchmarking and model validationTaking research concepts through to reliable production systemsImproving accuracy, latency, throughput, reproducibility and infrastructure efficiencyOptimizing model training and inference across GPU environmentsContributing to proprietary and potentially patentable AI technologyHelping define future model architecture and technical directionMaintaining direct ownership of your work from initial concept through deploymentThis is not a position where you will inherit narrowly defined tickets or operate several layers away from technical decision-making. You will have the freedom to challenge assumptions, explore new approaches and influence how the company builds its core AI capabilities.What we’re looking for:At least five years of professional AI/ML, research or closely related software-engineering experienceStrong evidence of personally building, training or materially modifying machine-learning modelsExperience fine-tuning and deploying models within production environmentsAdvanced Python development skillsCommercial experience with PyTorch, JAX, TensorFlow or comparable frameworksA strong understanding of modern deep-learning and model-training techniquesExperience measuring and improving model performanceThe ability to work independently within technically ambiguous environmentsExperience delivering AI capabilities within a commercial or B2B settingA key area of interest is practical experience improving the performance of computationally intensive models.This could include:CUDA or GPU-accelerated model developmentTraining and inference optimizationDistributed or multi-GPU trainingQuantization, compilation or model compressionMemory and compute optimizationHigh-throughput or low-latency model servingProfiling and resolving model-performance bottlenecksIf you are an experienced AI/ML Engineer based in Austin and want full technical ownership of meaningful model-development work, apply directly or contact me for a confidential conversation.
