Founding AI / ML Engineer

Company Description
Atrisa (YC P26) builds AI agents for analog circuit design. We are building AI that takes a circuit from specification to layout, working with the simulators and design tools engineers use today.
Role Description
This is a Founding AI / ML Engineer role, full-time and hybrid in Bangalore. We are open to visa sponsorship.
Train and fine-tune models for analog circuit design.
Build reinforcement learning pipelines, simulation environments, reward functions, and evaluations grounded in circuit performance.
Build agents that interact with circuit simulators and design environments, from setting up a run to interpreting results and choosing the next step.
Build observability into agent runs. Detect and prevent failures, and design recovery paths when tools, simulations, or model decisions go wrong.
Work with analog engineers to distill their design intuition into training data, models, and agent harnesses.
Qualifications
At least 3 years of relevant AI / ML engineering experience, with hands-on model training or fine-tuning.
Strong Python skills and experience with PyTorch or an equivalent framework.
Experience building agents that call tools, manage state, and carry out multi-step tasks.
Experience designing evaluations and debugging failures across models, data, and software.
Familiarity with reinforcement learning, reward design, or training environments is a plus.
Experience with analog circuits, EDA tools, SPICE, or scientific computing is a plus.
