      <Title>Machine Learning Engineer, Global Public Sector</Title>
      <Description><![CDATA[<p>We&#39;re hiring a Machine Learning Engineer to bridge the gap between frontier research and real-world impact. As a key member of our GPS Engineering team, you will lead the charge in research into Agent design, Deep Research and AI Safety/reliability, developing novel methodologies that not only power public sector applications but set new standards across the entire Scale organisation.</p>
<p>Your mission is threefold:</p>
<ul>
<li>Frontier Research &amp; Publication: Leading research into LLM/agent capabilities, reasoning, and safety, with the goal of publishing at top-tier venues (NeurIPS, ICML, ICLR).</li>
<li>Cross-Org Impact: Developing generalised techniques in Agent design, AI Safety and Deep Research agents that scale across our commercial and government platforms.</li>
<li>Mission-Critical Applications: Engineering high-stakes AI systems that impact millions of citizens globally.</li>
</ul>
<p>You will:</p>
<ul>
<li>Pioneer Novel Architectures: Design and train state-of-the-art models and agents, moving beyond “off-the-shelf” solutions to create custom architectures for complex public sector reasoning tasks.</li>
<li>Lead AI Safety Initiatives: Research and implement robust safety frameworks, including red teaming, alignment (RLHF/DPO), and bias mitigation strategies essential for sovereign AI.</li>
<li>Drive Deep Research Capabilities: Develop agents capable of long-horizon reasoning and autonomous information synthesis to solve complex problems for national security and public policy.</li>
<li>Publish and Contribute: Represent Scale in the broader research community by publishing high-impact papers and contributing to open-source breakthroughs.</li>
<li>Consult as a Subject Matter Expert: Act as a technical authority for public sector leaders, advising on the theoretical limits and safety requirements of emerging AI.</li>
<li>Build Evaluation Frontiers: Create new benchmarks and evaluation protocols that define what success looks like for high-stakes, non-commercial AI applications.</li>
</ul>
<p>Ideally, you’d have:</p>
<ul>
<li>Advanced Degree: PhD or Master’s in Computer Science, Mathematics, or a related field with a focus on Deep Learning.</li>
<li>Research Track Record: A portfolio of first-author publications at major conferences (NeurIPS, ICML, CVPR, EMNLP, etc.).</li>
<li>Engineering Rigour: Strong proficiency in Python, deep learning frameworks (PyTorch/JAX), with the ability to write production-ready code that scales.</li>
<li>Safety Expertise: Experience in alignment, robustness, or interpretability research.</li>
</ul>
<p>Nice to haves:</p>
<ul>
<li>Experience with large-scale distributed training on massive clusters.</li>
<li>Experience in building agentic systems that are reliable.</li>
<li>Experience in Sovereign AI or working with highly regulated data environments.</li>
<li>A zero-to-one mindset: Comfortable navigating ambiguity and defining research directions from scratch.</li>
</ul>
