Research Engineer (Agentic systems, AI, Full-Stack)
Research Engineer
Overview
Physical Superintelligence is a stealth startup with roots at Google, Harvard, Meta, MIT, Oxford, Johns Hopkins, Cambridge, and the Perimeter Institute building AI systems to discover new physics at scale. We are seeking engineers to build platform infrastructure at the intersection of computational science, AI systems, and software engineering.
Our mission is to discover and commercialize transformative physics breakthroughs at scale with artificial superintelligence - safely, verifiably, and for broad public benefit.
The last century's golden age of physics gave us transistors, lasers, and nuclear energy. We believe artificial superintelligence will unlock the next one. We're creating the infrastructure to industrialize scientific discovery and usher in this new era.
We have one product: new physics, at scale.
Role and Responsibilities
Develop a complex agentic system to support emerging superintelligence, with a focus on solving challenges in physics.
Work across computational science simulation, AI systems, full-stack development, and infrastructure to build the platform enabling AI-driven physics discovery. This role requires fluency in scientific computing concepts, modern software engineering practices, machine learning infrastructure, and production systems design.
Design production-ready systems, including security considerations.
Build infrastructure supporting model training, evaluation, and deployment with experiment tracking, versioning, and reproducibility systems
Implement orchestration for machine learning workloads across cloud infrastructure and develop instrumentation for understanding agent behavior and scaling
Build production web applications serving research teams and external customers with responsive interfaces, backend services, and APIs
Create containerized architectures and orchestration systems with CI/CD pipelines, infrastructure as code, GPU scheduling, and compute resource management
What We're Looking For
We seek candidates with a track record building production systems that technical users adopt, along with strong fundamentals across software engineering, computational methods, and infrastructure. You should have depth in at least two to three relevant technical areas and the ability to work across the full stack from scientific computing to production deployment.
Programming and software engineering:
Python, or similar systems languages with full-stack development using React, TypeScript, Next.js, and modern web frameworks
Backend services, REST and GraphQL APIs, data systems including PostgreSQL and Redis, and real-time systems
Infrastructure and MLDevOps:
Docker, Kubernetes, container orchestration, cloud platforms including AWS, GCP, or Azure, and infrastructure as code using Terraform
CI/CD pipelines, monitoring with Prometheus and Grafana, GPU scheduling, and compute resource management
Machine learning infrastructure:
PyTorch, JAX, or similar frameworks with experiment tracking systems such as MLflow or Weights & Biases
Orchestration frameworks including Ray, Airflow, or Argo, and distributed training infrastructure
Scientific computing and domain knowledge:
High-performance computing environments, physics simulations or domain-specific scientific software
Building tools at AI labs, machine learning-focused startups, or research organizations
Location and Compensation
This is an in-person role based in Boston or San Francisco or San Jose. We offer competitive compensation including salary, benefits, and meaningful early-stage equity. We evaluate on technical breadth, systems thinking, scientific curiosity, and shipping velocity. We are an equal opportunity employer and value diverse perspectives in building platforms for AI-driven discovery.
