About the role
- 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.
Responsibilities
- Own end-to-end security strategy for PSI.
- Application security, cloud security, identity and access management, secrets management, audit logging, and detection and response are yours to design and run.
- Set the security bar in architecture and design reviews across the AI platform.
- Build and lead the security function as PSI scales.
- Lead SOC2 readiness and, at the right time, additional compliance programs such as ISO 27001 and customer-specific security questionnaires.
Requirements
- Eight or more years in security engineering at scale, with a track record at companies known for security maturity (e.g., Google, Stripe, Cloudflare, Microsoft, Apple, Snowflake, Databricks, Palantir, or comparable).
- You have built security functions, not just contributed to them.
- You know how to translate compliance language into engineering reality without slowing shipping velocity.
- Demonstrated ability to set strategy and operate without bureaucracy.
- You have been a founding or near-founding security hire at a fast-growing company
- you have built threat models, incident response runbooks, and a small high-leverage team without becoming a process department.
Nice to have
- Background in AI and ML security: model weights protection, prompt injection defense, agent supply chain, training data integrity, red teaming for LLMs.
- Public security research, conference talks at top venues (Black Hat, DEF CON, USENIX Security), CVE discovery, or substantial open-source security contributions.
- Experience designing multi-tenant isolation and security architecture in agentic systems, research platforms, or scientific computing infrastructure.
- Government clearance, classified-program background, or experience protecting IP-bearing scientific or research environments.
- This role is based in Boston.
- We evaluate on technical breadth, systems thinking, scientific curiosity, and shipping velocity.
Compensation
- This role is based in Boston.
- We will consider remote candidates on a case-by-case basis.
- We offer competitive compensation including salary, benefits, and meaningful early-stage equity.
- We evaluate on technical breadth, systems thinking, scientific curiosity, and shipping velocity.
Company info
- Own incident response, third-party and model-provider risk, and the security relationship with enterprise customers in physics, energy, and adjacent verticals.
- We are seeking engineers to build platform infrastructure at the intersection of computational science, AI systems, and software engineering.
Equal opportunity
- We are an equal opportunity employer and value diverse perspectives in building platforms for AI-driven discovery.
