The posting

We are

48% of breaches now come through vendors. Yet most companies still manage vendor risk through certifications and questionnaires, essentially trusting what vendors say about their security. Lema changes that. We analyze every vendor like a vulnerability researcher would: how could an attacker use this vendor to get in, and what could they reach?

We’re turning vendor risk from a paperwork exercise into a true security discipline. Backed by Team8, Salesforce Ventures, and F2, and already trusted by leading enterprises, Lema is entering hypergrowth and tripling our team to build a category-defining platform.

We move fast, with radical ownership, transparency, and high impact.

About the Role

We're looking for a security researcher with 5+ years of experience to discover new ways vendors put their customers at risk. You'll own research end to end, from the first hypothesis to a shipped capability, and help decide where Lema looks next.

What You'll Do

  • Discover new ways attackers can use vendors to get in, and prove or kill each idea with real data.
  • Decide which security tools and data sources we should integrate next, and why.
  • Shape the logic and knowledge behind our AI risk agents.
  • Build your own tools when the one you need doesn't exist.
  • Partner with engineering to turn validated research into product.
  • Work alongside the best security researchers in the industry.

Requirements

What You Bring

  • 4+ years of hands-on experience in security research, threat intelligence, or offensive security.
  • Original research to show: vulnerabilities, techniques, tools, or findings.
  • A strong grasp of core security domains, including identity, cloud, SaaS, endpoint, and network, and how they connect.
  • Rigor. You prove a finding before you claim it, and you read AI output adversarially.
  • Independence. You take a fuzzy question and turn it into a result without needing each step defined.
  • A track record of research that became a product, a detection, or a published finding.

Why Join Lema AI

  • Impact: Build a category-defining platform that safeguards how modern businesses operate.
  • Ownership: Join a culture that gives you full context, autonomy, and trust to drive outcomes.
  • Compensation & Benefits: Competitive salary, equity package, and additional perks
  • Velocity: Work with exceptional peers in a high-energy, low-bureaucracy environment.
  • Growth: Shape a company that’s scaling rapidly, backed by Tier 1 investors and visionary customers.

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.
