CTO (Chief Technology Officer) – AI SLEIPNIR – Revolutionizing Crypto with Advanced AI & Post-Quantum Tech

📧 Send to: [email protected] | Subject: CTO Application – [Your Name] – [Challenge Chosen e.g. Option A] READ THE TEXT UNTIL THE END, PLEASE.

Why This Role?

You’re not the CPO—you’re the CTO, and here’s what that means at AI SLEIPNIR:

✅ Own the Tech Stack: You architect, build, and scale our AI-driven crypto engine (e.g., LLM/embedding-based anomaly detection, predictive analytics) alongside post-quantum cryptography (PQC)—while our CPO defines what we build, you decide how we build it 100x better than anyone else.

✅ Equity Upside: No salary? No problem. We’re offering 0.5–2%+ equity (negotiable) because we believe in alignment over cash. This is your chance to own the tech behind a future unicorn.

✅ Bleeding-Edge Challenges:

• AI for Crypto: Implement embedding-based anomaly detection, predictive key rotation, and semantic crypto-analysis using advanced LLM or alternative AI models.
• Post-Quantum Readiness: Integrate PQC algorithms alongside classic primitives .
• Zero-Knowledge Architecture: Ensure server-never-sees-plaintext security at scale.

✅ Lead the Engineering Team: Hire and mentor crypto engineers, backend devs, and AI/ML specialists—starting with a 5-person core team (growing fast).

✅ Collaborate with CPO: Work hand-in-hand with our Chief Product Officer to translate product requirements into bulletproof technical solutions.

🎯 What You’ll Do (First 12 Months)🚀 Phase 1: Build the Core (Months 1–6)

Architect the a new platform:

• API-First Design: Modern API paradigms (e.g., RESTful/GraphQL) with endpoints like /v1/encrypt, /v1/sign, /v1/ai/analyze.
• AI Integration: Embedding pipelines for anomaly detection, predictive analytics, and algorithm recommendations (using LLMs or alternative AI models!!).
• Hybrid Crypto Engine: Seamless integration of classic + PQC algorithms with graceful degradation.

Ship the MVP:

• Minimal viable API (encrypt/decrypt/sign/verify) in high-performance languages (e.g., Rust, C++, Go) with library support (we already have a foundation).
• AI Predictor v1: Basic embedding-based threat detection for crypto operations.
• HSM Integration: Abstracted layer for multi-vendor HSM support (e.g., AWS CloudHSM → Thales/YubiHSM/Utimaco).

Hire the Founding Engineers:

• Senior Backend Engineer (Rust/C++/Go) – already secured.
• Crypto Engineer (PQC specialist) – candidate in pipeline, not yet confirmed.
• AI/ML Engineer (embeddings/LLMs) – needed urgently.

📈 Phase 2: Scale & Harden (Months 7–12)

Performance Optimization:

• for all operations (target: ).
• Hardware acceleration (e.g., AVX512, GPU for AI workloads).
• Edge deployment for low-latency global access.

Enterprise Readiness:

• Multi-tenant Key Management System (KMS) with strict key isolation.
• Compliance frameworks: SOC2, ISO27001, FIPS 140-3 (collaborate with CPO on requirements).
• HSM multi-vendor support (Thales, YubiHSM, Utimaco, etc.).

Expand the Team:

• DevOps/SRE Engineer (Terraform, K8s, monitoring).
• Full-Stack Engineer (SDKs, developer portal)

🏆 Phase 3: Dominate (Year 3+)

AI-First Crypto:

• Advanced LLM models for document signing (semantic integrity checks).
• Predictive compliance (auto-audit against GDPR, eIDAS 2.0).
• we are building a new product category

Global Infrastructure:

• Multi-region deployments (EU, US, APAC). When funding is finshed.
• 99.99% SLA with auto-scaling HSM farms.

Thought Leadership:

• Open-source AI-driven crypto tools.
• Whitepapers on PQC + AI synergies.

🎯 Who You Are | ✅ Must-Haves (Non-Negotiable)

• 10+ years in engineering leadership (CTO, VP Engineering, or Senior Architect in high-scale, security-critical products).
• Deep crypto expertise: Mastery of cryptographic primitives and PQC algorithms at a protocol level.
• AI/Embeddings Fluency: Experience with LLMs, embedding models, or alternative AI systems and their application to crypto/security use cases (e.g., anomaly detection, predictive analytics).
• Systems Architecture: Designed and scaled distributed systems (10k+ ops/sec) with .
• Hands-on Coder: Write production-grade code (e.g., Rust, Python, Go, C++) and review PRs—this is a technical, not managerial-only role.
• Startup Fit: Thrive in ambiguity, prioritize ruthlessly, and ship fast with limited resources.
• 24/7 working mentality on the company, if this is to much, then you are not the right fit
• start immediately

🚀 Nice-to-Haves

• HSM Experience: AWS CloudHSM, Thales, YubiHSM, or Utimaco integrations.
• AI/ML Background: Built embedding-based systems, predictive models, or LLM applications.
• Security Certifications: CISSP, CISM, or FIPS/Common Criteria compliance work.
• Open-Source Contributions: Especially in crypto, AI, or infrastructure.
• Remote Team Leadership: Scaled engineering teams across time zones.

💡 Why You’ll Love This (Beyond Equity)

• Technical Ownership: You control the architecture—no product managers dictating how to build (just what to build).
• Impact: Secure the post-quantum future for enterprises worldwide with AI superpowers.
• Learning: Master cutting-edge AI, PQC, and modern crypto at the bleeding edge.
• Collaboration: Work with a CPO who understands tech—no ivory tower, just aligned execution.
• Legacy: Build a developer-loved platform (think "Stripe for crypto, but with AI superpowers").

📩 How to Apply

This isn’t a resume drop. Show us how you think:

1️⃣ Solve a Technical Challenge(pick one):

• Option A (Crypto + AI): Design a hybrid RSA + Kyber encryption system with AI/embedding-based anomaly detection. Explain your model strategy and performance trade-offs (

• Option B (Scalability): How would you scale a CaaS API to 1M ops/sec while maintaining and HSM security?

• Option C (Architecture): Sketch a high-level diagram of how you’d integrate LLM/embedding models into a document signing service for semantic integrity checks.

2️⃣ Share Your Work:

• GitHub profile (if you code)
• Architectures you’ve designed (even proprietary)
• Tech blog posts/talks (crypto, AI, or distributed systems)

3️⃣ Tell Us:

• Your biggest technical win (and what you’d do differently).
• Why equity > salary for you right now.
• Your favorite crypto or AI paper from the last year (and why).

⚠️ The Fine Print

• Compensation: Equity only (pre-revenue, aggressive fundraising in progress). Target: 0.5–2%+ (negotiable based on experience).
• Location: Remote-first, but EU/Germany preferred (for compliance and team overlap). You have to be able to be here in the office at Düsseldorf. For some limited time you can work remotely .
• Timezone: Must overlap 4+ hours with CET (UTC+2).
• Start Date: ASAP (we’re moving at startup speed).
• Culture: No ego, no politics, no bullshit. We ship, measure, and iterate.

🔥 Final Pitch

You won’t be the CPO—you’ll be the CTO who makes the CPO’s vision technically possible!

If you’ve ever wanted to:

✅ Build the Stripe of encryption (but with AI superpowers), we are building a new product category not some bs saas model + tokens !

✅ Out-engineer AWS and Google in cloud security.

✅ Own the tech stack of a future unicorn—before it’s a unicorn.

Then let’s build it together.

P.S.: If you’re on the fence, apply anyway. We value grit, curiosity, and execution over perfect fits.
