Member of Technical Staff, Recursive Self-Improvement (RSI)

Mirendil Mirendil is a tech-first company focused on solving core bottlenecks that unlock step-change acceleration across science and technology. Our first goal is to democratize frontier AI R&D across scientific disciplines. We are building a frontier AI research company and training our own models end-to-end. THE ROLE We are looking for an innovative, rigorous Research Engineer to join our team to accelerate AI self-improvement.

This role requires a deep understanding of ML at both the application and system levels. You will ship AI-driven systems that recursively improve how AI systems are trained, evaluated, deployed, and operated at scale. If you are driven by the compounding potential of accelerating the AI loop, you will thrive in this role.

Areas you might work on include:

• Build autonomous AI that improves AI. Develop models, harnesses, and pipelines that automate parts of the ML lifecycle - data curation, training optimization, debugging, model selection, and experiment execution - and measure their impact on the speed and reliability of AI R&D.
• Close loops across the stack. Identify the highest-leverage improvement opportunities anywhere in the stack, from distributed pre-training, post-training, and serving to agent harnesses, runtimes, and research environments, and jointly design and optimize across layers.
• Run experiments end-to-end. Form hypotheses, design experiments, build the infrastructure to run them at scale, and turn results into shipped improvements.
• Develop evaluation and observability. Build benchmarks, automated evals, and monitoring systems that surface regressions, failure modes, and emergent behaviors in AI systems. If you're excited about closing the loop at scale, we'd love to hear from you. We offer a base salary of $300,000–$400,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.
