About the role

Key responsibilities & impact

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.
Use frontier LLMs as your primary partner for learning unfamiliar codebases, reading log schemas, reasoning through threat models, and accelerating your output as a working software engineer.
Build LLM-powered classifiers and rule-based detections that turn raw log data into actionable alerts for the Security team.
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.
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.

Requirements

What you’ll need

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.
Fluency writing code in at least one general-purpose language (Go or Python preferred).
Comfort using frontier LLMs as a coding partner.
Ability to take a fuzzy problem and turn it into a scoped, shippable piece of work.
Curiosity about how systems get attacked and defended, even if you've never formally studied security.
Strong written communication.
