The posting

The company secures the AI-driven SDLC from prompt to production, unifying development and cloud context to stop vulnerabilities at the source. The Security Research group is hiring a senior, hands-on Application Security Researcher to push modern AppSec forward — working with engineers, researchers and AI/data scientists on next-generation detection, including autonomous, agentic pen-testing capabilities. This is a build-and-break role, not a typical AppSec position.

Requirements

Must-have skills:

  • 5+ years hands-on in offensive security, vulnerability research, or application security
  • Deep understanding of web application and API vulnerabilities, including business-logic flaws and multi-step attack chains
  • Strong coding in Python, Go, or similar, with production-quality code shipped
  • Experience building or tuning detection logic (SAST, DAST, SCA, secrets, or custom rule engines) and reducing false positives
  • Solid grasp of modern stacks: CI/CD pipelines, containers, Kubernetes, and at least one major cloud provider
  • Hands-on use of LLMs / AI models for security tasks, with the judgment to measure where they help and where they fail
  • Comfort with large datasets (SQL, BigQuery, or similar) to drive research and measure detection accuracy
  • Takes research ideas from prototype to production with minimal guidance
  • Clear written communication — can explain a complex attack path to engineers and product managers
  • M.Sc. in Computer Science, Cyber Security, or a related field

Nice to have:

  • Published research, CVEs, conference talks, or a bug bounty track record
  • Experience building AI agents or evaluation frameworks for LLMs
  • Background in exploit development, red teaming, or penetration testing
  • Code analysis techniques (taint analysis, call graphs, reachability)
  • Contributions to open-source security tools

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
