About the Role
Gain is the Private Markets Super App, a connected global platform transforming how leading investors, advisors, and corporates source, evaluate, and execute deals. By combining investment-grade intelligence, AI-powered workflows, and proprietary data in one unified platform, Gain enables top deal teams to move faster, reduce risk, and build conviction with confidence. The work is roughly half LLM agents and half custom ML, leaning slightly toward agents.
Responsibilities
- Build and improve agents that find company data points on the web using search, page navigation and structured extraction tools, and that weigh conflicting sources before committing to an answer.
- Develop, improve and retrain the models that predict company financials such as revenue and EBITDA, and the likelihood and timing of buy and sell events.
- Design and maintain evaluation suites, both offline against reference sets and live in production, so we can measure quality and switch between LLM providers to balance output quality and cost.
- Ship your work into our production services, trace where pipelines fail, and fix the weakest links first.
- Design with resources in mind, choosing solutions with their compute, memory, bandwidth and model costs in view.
Requirements
- At least 3 years of building both custom ML models and LLM-based pipelines or agents, with work that ran in production rather than only in demos.
- Solid modelling fundamentals: feature engineering, validation that holds up on new data, and knowing when a model needs retraining.
- A habit of measuring before claiming; ability to build an evaluation set and tell an honest improvement from a lucky one.
- Strong Python, including async code.
- Experience with noisy or conflicting data sources and financial or private-company data is a plus.
