Systems Optimization Expert - AI Trainer
Obsidian
Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models. Overview We're seeking talented Performance Engineers with deep expertise in low-level systems optimization — specifically C++, Python, and Rust — to bring hands‑on technical excellence and elevate the quality of our AI training and inference infrastructure data. This role involves AI model training and evaluation work, including writing and assessing MLOps tasks and solutions to generate high-quality training data for frontier AI systems. This is a W‑2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce. This is a 40‑hour full‑time engagement, with no conflicts/no other engagements. Key Responsibilities Guide research and engineering teams to close knowledge gaps and improve AI model performance in systems‑level optimization, compiler engineering, and runtime performance topics. Design challenging, domain‑relevant tasks across multiple specializations, and write accurate and well‑structured solutions to performance engineering problems. Evaluate performance engineering tasks and solutions and provide clear, written technical feedback. Develop guidelines and detailed rubrics/evaluation frameworks to assess systems design quality across AI workloads. Collaborate with other subject matter experts to ensure consistency and accuracy in training data. Core Qualifications 2+ years of dedicated professional experience in performance engineering, systems programming, or low‑level optimization. Deep hands‑on expertise in at least one of the following: C++, Python, or Rust — with working familiarity across the others being a strong plus. Demonstrable track record of measurable performance improvements on production systems (e.g., latency reduction, throughput gains, memory footprint optimization). Demonstrable career progression. Ability to engage reliably for at least 30 hours/week during weekdays. Strong written communication skills and the ability to explain complex technical decisions clearly. Equal Employment Opportunity: Cincinnatus is proud to be an Equal Employment Opportunity employer. We do not discriminate based upon race, religion, color, national origin, sex (including pregnancy, childbirth, reproductive health decisions, or related medical conditions), sexual orientation, gender identity, gender expression, age, status as a protected veteran, status as an individual with a disability, genetic information, political views or activity, or any other legally protected characteristic. #J-18808-Ljbffr
