# Applied AI R&D Engineer

Testsigma is an AI-native company building autonomous agents that verify software as fast as AI can write it. AI has transformed how code is written, but not how it is trusted. When the same AI writes both a feature and the checks for it, both inherit the same blind spots. Our agentic AI coworkers act as the independent judge: they understand what changed in an application, identify what is at risk, adapt as the application evolves, and tell engineering teams whether a release is safe to ship, bringing in a human whenever judgment is needed. We're solving this in production for global enterprises such as Cisco, Samsung, DHL and IndusInd Bank. Testsigma is headquartered in San Francisco, with engineering in Bangalore, and is backed by MassMutual, Accel, Strive and Bold Cap. THE ROLE You'll join our AI team building the core agent layer of our platform, working directly with the founding team. The team is small, so your architecture decisions will shape the platform for years. This isn't a role for someone who chains LLM API calls and calls it agentic. The systems you build have deterministic rule layers, multi-stage reasoning pipelines, confidence scoring when the answer is ambi
