Posted May 14Security Engineering Intern - Summer 2026
at Lambdalabs
Remote
Responsibilities
- - Build LLM-powered classifiers and rule-based detections that turn raw log data into actionable alerts for the Security team.
Requirements
- Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers.
- Our customers range from AI researchers to enterprises and hyperscalers.
- If you'd like to build the world's best AI cloud, join us. *Note: This position requires presence in our San Francisco office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.
- About the Role Lambda Security protects some of the world's most valuable digital assets: invaluable training data, model weights representing immense computational investments, and the sensitive inputs required to leverage best of breed AI models.
- Between those sessions, your primary partner is a frontier LLM: you'll use it to learn log schemas, reason through threat models, and accelerate your way through code you've never written before.
- We expect interns to drive their own learning and use AI tools fluently; the bar for what a great junior engineer can ship has changed, and this role is designed around that change.
- The work spans LLM-based classifiers for sensitive data exposure, identity and access pattern detection, and the security infrastructure that everything else depends on.
- If you love writing code, are excited about working with AI tools to solve problems you couldn't solve alone, and find the idea of protecting AI infrastructure genuinely interesting - even if you've never taken a security class - we'd love to hear from you.
- What You’ll Do - Ship real production detections you develop against Lambda's real log data over the course of the summer, chosen with your mentor from a menu of high-value security gaps.
- - Work closely with your mentor in code reviews and threat hunting, and self-direct between them, using AI tools to investigate and sharpen your questions before bringing them to a human.
- What We’re Looking For - Currently enrolled in a Bachelor's or Master's program in Computer Science or a related field, returning to school after the summer. - Independent technical projects you've shipped: side projects, open source contributions, hackathons, research code, anything where you scoped a problem and built a working solution.
- Resumes that only list classwork are unlikely to stand out. - Fluency writing code in at least one general-purpose language (Go or Python preferred, but we care more about your ability to learn and leverage an LLM than your starting stack). - Comfort using frontier LLMs as a coding partner.
- You can tell when the model is wrong, push back on bad suggestions, and use it to accelerate learning rather than replace it. - Ability to take a fuzzy problem ("we need to know when someone overshares a sensitive document") and turn it into a scoped, shippable piece of work without needing a ticket pre-written for you. - Curiosity about how systems get attacked and defended, even if you've never formally studied security.
- Nice to Have - Prior software engineering internship. - Familiarity with cloud infrastructure (AWS, GCP, or similar), command-line environments, or systems-level programming. - You’ve built something with AI assistance that pushed beyond what you could have done alone. -
- Experience working with log data, structured event data, or building anything that processes streams of records. - Prior exposure to security concepts (a CTF you played, a security class you took, a side project you built, a security mistake you made and learned from, etc.). - Coursework or projects involving machine learning, data classification, or applied AI.
- About Lambda - Founded in 2012, with 500+ employees, and growing fast - Our investors notably include TWG Global, US Innovative Technology Fund (USIT), Andra Capital, SGW, Andrej Karpathy, ARK Invest, Fincadia Advisors, G Squared, In-Q-Tel (IQT), KHK & Partners, NVIDIA, Pegatron, Supermicro, Wistron, Wiwynn, Gradient Ventures, Mercato Partners, SVB, 1517, and Crescent Cove - We have research papers accepted at top machine learning and graphics conferences, including NeurIPS, ICCV, SIGGRAPH, and TOG - Our
Benefits
- Salary Range Information This is an hourly role, eligible for overtime.
Additional details
- Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence.
- We're responsible for securing every byte that powers breakthrough artificial intelligence.
- The detections you build will be the first line of warning when something looks wrong in our environment.
- You'll work alongside a senior engineer mentor on code review, security concept training, and unblocking your work.
- You and your mentor will pick the specific projects together, prioritizing where the data is richest and the business value is clearest.
- We value diverse backgrounds, experiences, and skills, and we are excited to hear from candidates who can bring unique perspectives to our team.
- If you do not exactly meet this description but believe you may be a good fit, please still apply and help us understand your readiness for this role.
- - Document what you build clearly enough that the on-call engineer who responds to your alert at 2am understands what it means and what to do.
- - Present your work at the end of the summer to the security team and company leadership, walking through what you shipped, what you learned, and what you'd build next.
- We can teach you security; we cannot teach curiosity. - Strong written communication.
