Upwork is an American freelance marketplace formed in 2015 from the merger of Elance and oDesk, and it connects businesses with independent professionals in software development, design, writing, marketing and increasingly artificial intelligence work. Its revenue comes from taking a percentage of what clients pay freelancers, which means it has spent years balancing take rate against the incentive for established pairs to leave the platform and transact directly. Headquartered in San Francisco and listed on Nasdaq, it has been positioning itself around higher-value professional work rather than competing at the commodity end of the market.
An enterprise client is seeking Biology subject matter experts (SMEs) with PhDs in Biology or closely related biological sciences to support a large-scale AI data project. Selected freelancers will apply their domain expertise to biology-focused content creation, data annotation, and content evaluation.
- Create biology-domain content according to provided project guidelines and requirements
- Annotate biology-related data using the client’s internal tools
- Review and evaluate biological content for quality, accuracy, and relevance
- Apply subject matter expertise when assessing specialized biology content
- Follow established annotation, evaluation, and content creation guidelines consistently
- Complete assigned work within the project timeline while maintaining high standards for quality and attention to detail
- A PhD in Biology or a closely related biological science
- Strong subject matter expertise within one or more areas of biological sciences
- Excellent analytical and critical-thinking skills
- Strong written communication skills
- Exceptional attention to detail
- Ability to interpret and consistently apply detailed project guidelines
- Comfort working with data annotation, content evaluation, or content creation workflows
- Ability to learn and work effectively within company-provided internal tools
- Prior experience with AI/LLM data projects, data annotation, scientific content evaluation, or similar work is a plus
