About the Role
The SandboxAQ R&D team is looking for a PostDoc resident to help us bring more AI to the domain of cybersecurity. We are interested in candidates with a strong theoretical background and interest in frontier research, who can apply those foundations and implement them in practice. A successful candidate will be comfortable building models from scratch, fine tuning existing ones, and running inference efficiently (both generative and quantitative). They will be able to design software systems around those models in close collaboration with our engineering department. They will be part of a diverse team consisting of ML experts, cryptographers, mathematicians, and physicists, where they will play a key role in efficient and effective enablement of the cutting-edge technologies being developed at SandboxAQ. How We Succeed Together We move fast, build with purpose, and are obsessed with making an impact. Our culture is built for those who want to be at the forefront of innovation, and it's guided by these core principles:
- We are passionate about solving real-world problems for our customers.
- We take deep ownership of our work and hold ourselves to the highest standards of excellence.
- We are a team that stands by our commitments to each other and our customers, building trust through reliability.
- We are proactive and action-oriented, always seeking opportunities to make a difference and drive our mission forward.
- We believe in amplifying our collective impact through collaboration.
- We are dedicated to seeing our projects through to the finish line, ensuring that every detail is accounted for and that our work has a lasting impact.
What You'll Do
- Perform exploratory data analysis and feature engineering on vast quantities of data
- Train models and build agents using the latest ML frameworks
- Work with the engineering team to integrate research outcomes into the product portfolio
- Present the work to broad audiences from academic to industry
About You
- PhD in Machine Learning, Data Science, Computer Science or related field with a strong focus on Machine Learning
- Strong experience in Python, and ML frameworks such as Huggingface Transformers, LangChain, Tensorflow or PyTorch
- Successful research track record in the field of ML
Nice to Have
- Experience with agentic frameworks such as OpenAI agents, Google ADK, or MCP
- Experience contributing to open source projects
- Experience in the cybersecurity domain is a plus, but not essential
