- Strong proficiency in Python and modern ML frameworks such as PyTorch or TensorFlow, with experience developing and deploying AI systems.
- Deep understanding of core ML concepts, including transformers, generative models, and agent architectures such as MCP or A2A.
- Experience training large models on GPU clusters and integrating LLMs with external tools via APIs or orchestration frameworks.
- Comprehensive understanding of foundational deep learning, machine learning concepts, and state-of-the-art GenAI models.
- Hands-on experience training custom LLMs on GPUs and working with Retrieval-Augmented Generation (RAG) systems.
- Proven ability to build end-to-end ML pipelines—from data prep and experimentation to production deployment—in a cloud-native environment.
- A growth mindset, strong communication skills, and the ability to translate complex technical work to stakeholders across functions.
- Demonstrated experience working in R&D environments; publications in major AI/ML conferences are a plus, but not required.
- Architect and implement core infrastructure to support agent-based LLM systems, including multi-agent pipelines, RAG, and real-time orchestration.
- Train and fine-tune custom models, including LLMs and foundation models, to solve unique Upwork-specific challenges.
- Lead cross-functional collaboration across engineering, product, and research teams to align technical solutions with business impact.
- Mentor and guide engineers and researchers, helping foster a high-performing, inclusive team culture grounded in AI excellence.
- Translate experimental ideas into reliable, scalable production systems by applying best practices in AI engineering and deployment.
- Publish and share innovations where appropriate, contributing to Upwork’s visibility in the broader AI/ML research community.
