- The Prism team builds the systems that turn Elastic Security’s raw data into a trustworthy picture of the users, hosts, and services in a customer’s environment
- We power the Entity Store, entity risk scoring, entity resolution, and the data maintainers that analysts rely on to understand who did what, what’s risky, and what to investigate next
- We build features that have to work at scale, and we care deeply about correctness and performance
- As a senior engineer, you will lead technical work across this area
- You’ll partner with product, design, and engineering to turn hard, ambiguous problems into reliable, performant systems that ship to real security teams
- We’re a distributed team — we work across time zones and collaborate in GitHub, Slack, design reviews, and code reviews
- Own small-to-medium projects from technical design through production, including data modeling, background tasks, and APIs
- Make our features fast and reliable at scale: profile and optimize queries, tame timeouts, and design for a range of customer topologies
- Write high-quality TypeScript and React code, with Node.js services and APIs where needed
- Build telemetry, tests, and safeguards so the systems behave predictably in production
- Review code, support teammates, and improve team practices
