The Applied Machine Learning Ark team combines system engineering and machine learning to develop and operate Large Language Model (LLM) service platforms that offer businesses Model-as-a-Service (MaaS) solutions, serving both large model providers and downstream users. The US team drives the design, development, and operation of MaaS solutions across the US and international markets outside mainland China. We are building full-stack, end-to-end solutions spanning text and multimodal LLM algorithms, LLM training/fine-tuning/inference frameworks, prompt engineering, model alignment, and intelligent agent systems. Beyond model serving, we operate large-scale log analytics pipelines that process massive volumes of invocation logs from text models, multimodal models, and agent systems — extracting usage patterns, quality signals, and actionable insights to inform model improvement, system optimization, and product decisions through continuous, data-driven feedback loops. We are actively seeking talented engineers and researchers specializing in Large Language Models and AI Agent systems to join our dynamic team.
We are looking for talented individuals to join our team. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth.
Successful candidates must be able to commit to an onboarding date by the end of the year. Please state your availability and graduation date clearly in your resume.
Candidates can apply to a maximum of two positions and will be considered for jobs in the order you apply. The application limit is applicable to our Company and its affiliates' jobs globally. Applications will be reviewed on a rolling basis - we encourage you to apply early.
Responsibilities:
- Build evaluation systems for image and video models/agents, covering generation quality, instruction following, multimodal understanding, and safety.
- Develop automated metrics and model-based evaluators, and design reproducible human evaluation protocols.
- Design and develop video generation/debugging agents that orchestrate multi-step creative workflows.
- Build large-scale image and video data pipelines, and turn evaluation findings into model and product improvements.

- Solid foundation in deep learning and computer vision, including generative modeling fundamentals.
- Practical experience in at least one of: visual generation, multimodal LLMs, video understanding, or visual quality assessment.
- Strong Python skills and proficiency with PyTorch or an equivalent framework, or multimodal evaluation framework.
- Demonstrated research or engineering ability through publications, substantial projects, internships, or open-source work.
Preferred Qualifications:
- Publications at top-tier vision or ML venues, e.g., NeurIPS, ICML, CVPR, ICCV, ECCV, etc.
- Hands-on experience with modern visual generation stacks, including diffusion-based models and their post-training.
- Familiarity with visual generation benchmarks, or experience building evaluation frameworks.
- Experience applying agent frameworks to creative workflows, or working with large-scale video data infrastructure.
