<p>Constructor’s mission is to enable all educational organisations to provide high-quality digital education to 10x people with 10x efficiency. </p>
<p>With strong expertise in machine intelligence and data science, Constructor’s all-in-one platform for education and research addresses today’s pressing educational challenges: access inequality, tech clutter, and low engagement of students.</p>

<p><strong>The Reality</strong></p>
<p>The frontier models are converging into commodities; the engine is no longer the differentiator. The scarcity in 2026 is not the model.</p>
<p>We are not looking for people to fine-tune Llama on toy datasets or write "better prompts." We are building the runtime systems that turn probabilistic token generation into reliable workers that finish 50-step tasks without spiraling. We are solving the math of multi-step reliability through engineering, not wishful thinking.</p>
<p><strong>What You Will Solve</strong></p>
<p>You will work on the <strong>Agentic Harness</strong>, treating the LLM as a component within a larger, deterministic control system. Your research will focus on:</p>
<ul>
<li>Architecting loops that survive error accumulation. You will build verification layers that force the agent to recognize its own hallucinations and self-correct.</li>
<li>You will implement systems where the agent compiles its own constraints and the harness enforces them via constrained decoding or external execution.</li>
<li>You will optimise KV-cache hit rates and design "restorable compression" strategies to prevent attention decay.</li>
</ul>
<p><strong>Who We Are Looking For</strong></p>
<p>We are looking for <strong>systems thinkers</strong> who happen to know ML, not the other way around.</p>
<ul>
<li>You know that a demo is not a product. You are interested in the "boring" engineering: state machines, retries, idempotency, serialisation — that actually makes agents work.</li>
<li>You are comfortable working with the raw output of the model and building robust software in Python or Rust around it.</li>
<li>You understand why dynamic tool loading destroys inference economics. You prefer deterministic guardrails over "prompting it to be nicer."</li>
<li>You are willing to read a 500-line trace of a failed agent loop to find the exact moment the context drifted. You care about the "last mile" of reliability.</li>
</ul>
