Skills: Python, JavaScript, Git, AWS, GCP
Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Build and ship features across the full stack, from backend services to product surfaces. Take ownership of projects from design through delivery to improve the reliability and performance of the Policy Engine.
Pursuing a Bachelor's degree in Computer Science or a related technical field with strong programming fundamentals. Must be proficient in Python or JavaScript and comfortable with Git and cloud workflows.
Despite massive investment in commercial AI, organizations often find that demonstrated value is elusive, primarily due to the non-deterministic risk inherent to generative models. CTGT is the deterministic governance layer that enables the most important global institutions to deploy AI workflows with confidence.
Born out of Stanford University research, we provide the control plane that makes it possible. A lightweight, model-agnostic system that enforces policy, prevents drift, and produces auditable decisions in real time. When benchmarked on HaluEval, the CTGT Policy Engine (paired with GPT-120B OSS) outperformed frontier models (Gemini 3 Pro Preview, Claude 4.5 Opus and 4.5 Sonnet) at drastically lower compute cost.
While we sit on the edge of AI research, CTGT brings frontier intelligence into real-world environments. We apply cutting-edge theory directly in production to make large language models more reliable, controllable, and performant in practice.
Our mission is to bring models to the level of performance and accountability required by the Fortune 500. By bridging the gap between LLM capabilities and domain-specific requirements, we unlock the true potential of generative AI to solve the most pressing problems in our world today.
This is not a side project internship. You will own a meaningful piece of work end to end, ship it to a real system, and see it used. You will sit close to the engineers building the Policy Engine and the platform around it, and you will be expected to form opinions, ask hard questions, and take problems further than they were handed to you.
We are looking for someone whose strength is the fundamentals: someone who writes clean code, reasons carefully about correctness, and wants to understand the whole system rather than just the piece in front of them.
Build and ship features across the stack, from backend services to product surfaces
Write code that holds up under real load, with the correctness and clarity our systems require
Work closely with senior engineers and take ownership of a project from design through delivery
Dig into ambiguous problems and bring back a clear answer
Pursuing a Bachelor's degree in Computer Science or a related technical field
Strong programming fundamentals and fluency in at least one general purpose language (Python and JavaScript are central to our stack)
Comfortable with Git and basic cloud workflows (AWS or GCP)
Able to explain technical ideas clearly to people with different backgrounds
Curious, self-directed, and able to make progress without constant scaffolding
Full-time, in person in San Francisco
10 to 12 weeks between May/June and August/September 2027
We sponsor US visas
World-Class Backing: You will join a venture-backed company with institutional investors including Google's Gradient Ventures, General Catalyst, and Y Combinator.
Real Impact: You will work directly on the core systems that determine how models perform in the wild. Your work ships into real, high-stakes environments where governance, auditability, and performance are non-negotiable.
Autonomy & Trust: We operate with a high degree of trust. You are expected to form strong technical opinions and execute on them.
The deterministic layer for frontier intelligence
Generative AI is probabilistic. Your business is not. We are the frontier lab opening the black box. CTGT replaces fragile guardrails with representation-level control that delivers the mathematical certainty and defensible audit trails required by the Fortune 500.
