MTS - Research Scientist Internship

Collinear AI is developing data engines and evaluation systems for frontier artificial intelligence. The MTS - Research Scientist Intern will build high-fidelity agentic environments, verification and evaluation systems, post-training pipelines, and research infrastructure across computer use, enterprise tool calling, coding, and AI reliability.

Responsibilities:

• Build Agentic Environments: Design and implement the next generation of "SimLabs", ultra-realistic, long-horizon simulation environments where agents learn to navigate ambiguity and maintain context
• Programmatic and Agentic Verification: Develop rigorous, policy-aware judges and evaluations that measure genuine capability and safety beyond simple benchmarks
• Close the Loop: Design and execute high-quality post-training runs (CPT, SFT, RL) to deliver frontier performance on open-source models using curated, high-signal data
• Collaborate: Work daily with the founders and research staff to shape the roadmap and push the state-of-the-art in AI reliability
• Create. Work on analyzing model failure modes and creating frontier data pipelines which scale with test-time compute
