Job Details

ML Engineer at Excdev. Salary: 2500-3800 USD. Develop and optimize CUA agents, work with vision-language models, integrate and deploy LLM services, and scale the system. Remote work.

Develop and optimize CUA agents: increase accuracy of scenario completion, reduce the number of steps, improve handling of edge cases (captchas, non-standard UI, dynamic content). Design and implement new agent pipelines (multi-agent, judge-based architectures). Work with vision-language models (UI-TARS, Claude Vision): selection, fine-tuning, prompt engineering, quality assessment. Integrate and deploy LLM services (vLLM, OpenAI API, Anthropic API), optimize inference (tensor parallelism, batching). Participate in system scaling: increasing the number of simultaneously processed tasks, task parallelization, virtual machine resource management. Work with data: parsing, structuring results, integration with PostgreSQL and S3.

Required: Experience with LLMs in a production environment (prompt engineering, function calling, structured output). Experience building AI agents (LangChain / LangGraph / ReAct / Tools). Understanding of the architecture and principles of CUA / GUI agents (Anthropic Computer Use, UI-TARS or similar). Proficient in Python (asyncio, FastAPI or similar frameworks). Experience with Docker (building images, docker-compose, container management). Ability to read and reproduce ML research results (articles, benchmarks, open-source models). Nice to have: Experience deploying and optimizing LLM inference (vLLM, TGI, tensor parallelism). Experience fine-tuning vision-language models. Familiarity with multi-agent systems and agent orchestration. Experience with Anthropic API (including Computer Use). Understanding of web automation (Selenium, Playwright, pyautogui). Experience with PostgreSQL, SQLAlchemy, Alembic.

Work on an R&D project in the field of AI agents and LLM systems. Modern stack: Python, LLM services, vision-language models, agent architectures. Opportunity to work with cutting-edge solutions in Computer Use Agents. Remote work format from any city or country. Work schedule 5/2. Vacation - 28 calendar days.
