Company Description

CTGT, Inc. is a $7M Seed-funded AI safety startup backed by Google's Gradient Ventures, General Catalyst, and Y Combinator building a deterministic governance layer for enterprise AI workflows.

Job Description

As a Senior Software Engineer at CTGT, Inc., you will own the architectural evolution of a high-performance governance platform. You’ll design core services, manage distributed systems tradeoffs, and work across the stack to ensure AI workflows are correct, fast, and auditable for Fortune 500 clients in high-stakes industries like finance and healthcare.

Location

San Francisco, USA

Why this role is remarkable

• True Architectural Ownership: You aren't just shipping features; you're making foundational decisions about system decomposition, state management, and long-term trajectory that define the core platform.
• Elite Backing and Traction: Backed by Gradient Ventures and YC, CTGT, Inc. is already deployed in Fortune 500 environments with a Policy Engine that outperforms frontier models at lower compute costs.
• Frontier Engineering: Work at the intersection of mechanistic interpretability and production-grade software, building mission-critical systems where deterministic performance and auditability are non-negotiable requirements for global institutions.

What You Will Do

• Design and build core services that determine how the CTGT, Inc. platform decomposes and manages state under concurrent enterprise load.
• Architect internal APIs and abstractions that balance critical tradeoffs across accuracy, consistency, availability, and low-latency performance.
• Develop end-to-end solutions from data models to product surfaces, ensuring the Policy Engine stays reliable as the platform expands into new environments.

The ideal candidate

• Deep experience building non-trivial distributed systems with a proven track record of making architectural choices that scale and age well in production.
• Full-stack proficiency across Python, Rust, or TypeScript, with a strong grasp of the engineering fundamentals required to build complex systems correctly the first time.
• Strong technical opinions on software design and the ability to navigate complex tradeoffs between research-level AI capabilities and production-ready engineering requirements.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

How does this work?

• Jack's an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack's network.
• If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
