What you'll do
The Mission
CyberAGI is building the world’s first AI enterprise. We start with Excalibur, the AI-native offensive security engine that transforms cybersecurity from a cost center into a value generator.
This role is about owning engineering from the ground up. Not features. Not slideware. {The engine itself.}
Why This Role Exists
You will architect, build, and ship Excalibur end to end. That means:
Designing the AI-native system that ties threat modeling, pentesting, vulnerability management, and the CISO dashboard into one correlated story.
Making privacy the default with on-premise deployments where data never leaves customer environments.
Building the primitives, not patchwork. Simple, scalable, first-principles architectures.
Setting a ship cadence measured in running systems, not presentations.
Recruiting and leading an A-team that moves with attacker urgency and engineering precision.
Translating frontier customer problems into product outcomes that cannot be ignored.
The Mandate
Build the engine, not a feature. Architect Excalibur as one AI-native system that connects every module.
Make privacy the default. On-premise first. Data sovereignty is sacred.
Ship with first-principles clarity. Fewer moving parts, higher leverage.
Correlate, don’t enumerate. Every output must tell a living attack story, tied to real business impact.
Institutionalize speed. Convert ambiguity into code daily. No excuses.
What You’ll Do
Own the roadmap 0→1→N across:
Multi-framework threat modeling (STRIDE, DREAD, PASTA, MITRE) with pixel-to-context mapping.
AI-driven pentesting with drag-and-drop flows, safe validation, reproducible exploits.
Vulnerability lifecycle automation with developer-ready fixes.
CISO dashboards tying risk to ROI in real time.
Design and operate on-premise installs with air-gapped security and no phone-home.
Recruit, level up, and run a strike-team of A-players.
Set uncompromising reliability standards: deterministic pipelines around non-deterministic models.
Partner with frontier customers to convert their hardest problems into product primitives.
Non-Negotiables
First-principles thinking. Every decision grounded in physics-like clarity.
Relentless ownership. No hand-offs. You own the outcome.
Radical innovation. Eliminate whole classes of problems, not symptoms.
Privacy by design. Private by default. Always.
Hard work, non-stop improvement. This is not a 9–5. If you want comfort, go elsewhere. If you want to change the world, {this is it.}
Must be a US citizen.
Must know how to sell.
Who you are
Your Craft
Architecture: Distributed systems, event-driven pipelines, containerization, zero-trust by default, GPU and accelerator flows.
AI Systems: RAG at scale, multi-agent orchestration, evaluation harnesses, red-team loops, model safety, and tool safety.
Security: Offensive mindset, safe execution sandboxes, provenance and lineage, reproducible exploits.
Product Leadership: Taste in storytelling, ruthless prioritization, and the discipline to say “no” to preserve coherence.
Stack (indicative): Python (FastAPI), TypeScript/Next.js (ShadCN UI), Postgres/Supabase, Qdrant/Pinecone, Docker Compose/K8s, OpenTelemetry, GitHub Actions.
Signals You Might Be Our Person
You’ve built a {platform}, not just an app. Something that unified 3+ fragmented workflows into one coherent system.
You can whiteboard the architecture in the morning and ship a walking skeleton by Sunday night.
You thrive in ambiguity and can turn messy customer reality into crisp product primitives.
You’re calm under pressure, allergic to jargon, and opinionated — but you change your mind fast when the data shifts.
Our way of work
Think every problem with first principles,
Fast and incremental progress,
Question every requirement,
Delete any part that cause friction for UX,
Simplify and optimize,
Accelerate cycle time,
Automate.
