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.
