Penetration Tester at Weissman Cybersecurity · Trevo
Hey there,
We're Weissman Cybersecurity, and we're looking for a highly technical Penetration Tester / Offensive Security Engineer.
We are not a traditional consulting firm doing manual pentests. We are building a fully autonomous offensive-security and active-defense platform. Our product operates hundreds of live scanning engines that autonomously execute attacks and generate real proofs of exploit without human intervention. We need a hardcore attacker to help us upgrade our artillery.
What you'll do
Develop and refine our offensive probes, adding to our current arsenal of 563 production engine IDs and 303 live probes.
Ensure our coverage remains elite across all 15 attack domains and 192 MITRE ATT&CK techniques.
Research and implement state-of-the-art WAF evasion capabilities, such as advanced TLS and HTTP/2 fingerprint spoofing, to seamlessly bypass defenses like Cloudflare.
Integrate attack paths with our AI's "Pentest Reinforcement" memory. This system uses pgvector to remember what payloads worked on specific server fingerprints and automatically replays them on similar targets.
Work alongside our "Supreme Council" AI agents, ensuring the attack logic perfectly aligns with our strict policy of zero fabricated or randomized findings.
Requirements
Proven, hands-on experience in Penetration Testing, Red Teaming, or Vulnerability Research.
Absolute mastery of networking, OS internals, web/cloud attack vectors, and covert channels.
Deep understanding of AI limitations and data security. Our AI operates in hermetic isolation on a private GPU (vLLM) and executes queries using a strict read-only PostgreSQL role (weissman_ro) to guarantee zero data leaks. You must understand how to work safely around these guardrails.
Big plus: Experience writing high-performance code in Rust, as our core backend and engine logic are implemented entirely in Rust.
If you live and breathe offensive security, want to build autonomous cyber weapons alongside advanced AI, and hate corporate fluff – shoot us your CV or GitHub profile in a DM.
