About the Role

A well-funded Series A AI/ML platform company is looking for a Founding Engineer — ML Research to build and scale its research backbone. You'll bridge applied machine learning and systems engineering, turning cutting-edge ideas into reliable, production-ready models. As an early team member, you'll have direct impact on model performance, data quality, and the company's core technical foundations in generative and multimodal AI.

What You'll Do

• Design, train, and evaluate ML models — including LLMs, diffusion models, and domain-specific architectures.

• Develop scalable experimentation pipelines spanning data ingestion, model training, and evaluation workflows.

• Collaborate with data and infrastructure teams to optimize training throughput and model quality.

• Contribute to open research, internal benchmarks, and new techniques in multimodal and generative AI.

• Rapidly prototype research ideas and productionize them into usable models and tools.

• Define and promote standards for research rigor, documentation, and reproducibility across the engineering org.

What We're Looking For

• 3–10 years of experience in ML research, applied ML, or ML systems engineering.

• Deep familiarity with PyTorch, JAX, or TensorFlow and hands-on experience with architectures such as Transformers, Diffusion models, or RLHF.

• Strong foundations in data processing, distributed training, and evaluation metrics.

• Demonstrated ability to move from research papers to working prototypes to production-ready code.

• Curiosity about emerging ML paradigms — multimodality, self-learning, synthetic data, and agentic systems.

• Passion for building from zero to one in a high-velocity startup environment.

• Nice to have: Open research contributions, published benchmarks, or peer-reviewed publications in relevant ML research areas.

Compensation & Benefits

• Salary: $220,000 – $300,000 USD annually

• Equity participation as a founding team member

• Visa sponsorship: Not available — candidates must be authorized to work in the US

Location

This is an on-site role based in the San Francisco Bay Area / Mountain View, California. Remote arrangements are not available for this position.
