Join MultAI Technologies

We are building the infrastructure to survive Q-Day. Join our elite swarm of AI-augmented engineers and help scale the world's first production-ready, post-quantum privacy network.

Senior Systems Engineer

C++ / Windows / Post-Quantum Cryptography

Remote (Canada) / Alberta $120k – $165k CAD + Equity

The Mission

MultAI Technologies is commercializing the world's first production-ready, post-quantum Layer 1 privacy network (QRing) and its accompanying Layer 2 PQ-WASM execution engine (Qubit). We have solved the lattice-bloat problem. Now, we are scaling.

We are seeking a Senior Systems Engineer to own the native Windows integration of the QRing protocol and lead the architectural optimization of our L2 ecosystem. You will not just be writing code; you will be acting as a node in our Grand Agentic Station HQ (GAS:HQ). We arm our senior engineers with Gemini Code Assist Enterprise and ephemeral AI swarm instances to 10x your output. You will architect the solutions, delegate the syntax to the swarm, and rigorously audit the compiled output.

What You Will Do

  • Engineer native Windows executable (.exe) builds for the QRing node software from our core Linux C++ MVP.
  • Implement custom memory allocation routines ensuring strict alignment for Advanced Vector Extensions 512 (AVX-512) and Integer Fused Multiply-Add (IFMA) operations.
  • Drive the deployment and optimization of the Post-Quantum WebAssembly (PQ-WASM) L2 prototype.
  • Utilize our GAS:HQ swarm architecture to generate, test, and deploy code in ephemeral, zero-trust GCP environments.
  • Transition complex cryptographic workloads safely between operating system kernels without triggering processor faulting.

What You Bring

  • Deep C++ Expertise: 7+ years of low-level systems programming. You know how the Windows kernel handles memory.
  • Hardware Awareness: Experience with SIMD instructions, CPU microarchitectures, and hardware vectorization.
  • AI-Native Mindset: You view LLMs and AI coding assistants as force multipliers. You are highly proficient in planning, delegation, and rapidly iterating project goals via AI tooling.
  • Bonus: Background in applied cryptography, zero-knowledge proofs, or Web3 node architecture.

Senior Apple Systems Engineer

C++ / iOS & macOS / ARMv9

Remote (Canada) / Alberta $120k – $162.5k CAD + Equity

The Mission

MultAI Technologies is building the infrastructure to survive Q-Day. We are migrating our mathematically verified, lattice-based Layer 1 network into the hands of standard consumers.

We need a Senior Apple Systems Engineer capable of bridging hardcore cryptographic C++ with native iOS and macOS environments. You will be equipped with our proprietary GAS:HQ AI swarm orchestration platform, utilizing Gemini Code Assist Enterprise to automate rote development while you focus purely on high-level Darwin kernel integrations and ARMv9 hardware optimizations.

What You Will Do

  • Transform our operational Linux C++ build into highly optimized, native Apple (iOS/macOS) applications.
  • Interface custom memory allocators directly with Apple's Darwin kernel to maintain the exact alignments required for hardware-accelerated polynomial math.
  • Implement specialized matrix-based Number Theoretic Transforms (MatNTT) utilizing the ARMv9 Scalable Matrix Extension (SME).
  • Operate within the GAS:HQ framework, dictating deterministic Markdown tracks (spec.md and plan.md) to drive autonomous developer agents in isolated VPC sandboxes.
  • Ensure consumer nodes can process millions of polynomial multiplications over finite rings with zero thermal throttling.

What You Bring

  • Apple Ecosystem Mastery: 7+ years of experience with C++, Objective-C/Swift bridging, and native Apple application lifecycles.
  • Silicon Optimization: Deep understanding of Apple Silicon (M-series) architecture, cache lines, and ARMv9 vectorization.
  • The "Director" Paradigm: You are tired of manually typing boilerplate. You excel at defining strict parameters, delegating to AI agents, and reviewing PRs generated by the swarm.
  • Bonus: Familiarity with NIST post-quantum standards (ML-KEM, ML-DSA).
