Transform AI Research into Real-World Impact

As an AI Research Engineer at Pixalate, you'll bridge the gap between fundamental AI research and production systems that protect the digital ecosystem. Working with our Research team (AFAC) that has uncovered more than $100M in ad fraud and national security threats, you'll have the autonomy to pursue groundbreaking research while seeing your innovations deployed at scale within months, not years.

You'll lead research in emerging AI paradigms including autonomous agent systems, test-time compute optimization, and multimodal understanding - all applied to real-world challenges in digital safety and fraud detection.

Key Research Areas & Responsibilities

Agentic AI Systems Development
  • Design and implement multi-agent architectures for autonomous fraud detection and analysis
  • Develop sophisticated agent coordination systems using frameworks like LangChain, AutoGen, or custom architectures
  • Create tool-integrated AI agents capable of complex reasoning and decision-making
  • Research novel approaches to agent safety and alignment in production environments
Advanced Reasoning & Test-Time Compute
  • Implement state-of-the-art reasoning systems inspired by recent breakthroughs (o1, DeepSeek-R1)
  • Optimize inference-time compute allocation for complex analytical tasks
  • Develop chain-of-thought and verification mechanisms for high-stakes decision making
  • Research novel approaches to scaling reasoning capabilities efficiently
Multimodal AI & Knowledge Systems
  • Build advanced multimodal models for analyzing video, image, text, and behavioral data
  • Develop sophisticated RAG (Retrieval-Augmented Generation) architectures:
    • Design high-performance vector databases and hybrid search systems
    • Implement advanced chunking strategies and semantic understanding
    • Create context-aware retrieval mechanisms for complex documents
  • Research cross-modal learning for fraud pattern detection

    • Reinforcement learning and reward modeling
    • Neural architecture search and AutoML
    • MLOps and production ML systems
Research Skills
  • Track record of novel algorithm development and innovation
  • Experience with large-scale experimentation and ablation studies
  • Proficiency in research tools: Weights & Biases, MLflow, TensorBoard
  • Strong theoretical foundation in optimization, statistics, and linear algebra

Preferred Qualifications
  • Experience with fraud detection, cybersecurity, or trust & safety applications
  • Contributions to open-source AI projects
  • Industry research experience at leading AI labs (DeepMind, OpenAI, FAIR, etc.)
  • Experience translating research into production systems
  • Experience with:
    • Mixture of Experts (MoE) architectures
    • Constitutional AI and alignment techniques
    • Efficient inference optimization (quantization, distillation)
    • Real-time streaming ML systems
