Senior Full Stack Engineer

About this position

Comp AI is an AI-native compliance and security platform that launched in April 2025 and has achieved millions in ARR within a year. Our platform includes AI agents for evidence collection, policy drafting, control mapping, and continuous monitoring against various regulatory frameworks.

About Comp AI

We believe compliance is not a barrier but a foundation for continuous, AI-driven cybersecurity. Our mission is to build products that are always on and improve with usage. We are a small, agile team where each member's contributions are visible in the product.

About the Role

We are seeking a Senior Fullstack Engineer to build and own major parts of our platform, from the database to the API to the user interface. This role involves designing data models, building APIs, developing the frontend, and ensuring features are ready for customers in days rather than quarters. You will make architectural decisions, work closely with the founding team and product, and ensure the features meet customer needs.

How We Use AI (Central to the Role)

• Using AI coding tools like Claude Code as a primary part of your workflow.
• Knowing how to prompt, scope, and steer these tools toward production-quality output.
• Reading every line of AI-generated code and catching the mistakes.
• Holding the quality bar high, even with the acceleration provided by AI.

What You'll Do

• Build and own major features and surfaces end-to-end, including data model, API, frontend, and the infrastructure they run on.
• Make architectural calls and explain them clearly, designing systems that scale as the company grows.
• Set the engineering patterns the rest of the team follows.
• Build with AI, keeping it honest: use AI tools like Claude Code as a core part of your workflow, review AI-generated code carefully, and improve how the team works with AI.
• Ship fast: deliver to customers in days and weeks, then iterate based on their feedback.
• Build AI agents inside the product: evidence collection, policy drafting, control mapping, continuous monitoring.
• Hold a high bar on quality: ensure strong types, tests, and performance.
• Stay close and partner: talk to customers, partner with product, design, and founders, review PRs, mentor, and raise the bar around you.

You May Be a Good Fit If You Have

• 5+ years building production software, with full-stack shipping experience at an AI-native, infrastructure, devtools, security, or B2B SaaS company.
• Fluency with AI development tools (Claude Code, Cursor, Copilot, or similar) as part of your daily workflow, and a clear point of view on where they help and where they don't.
• The engineering depth to review AI-generated code and catch what is wrong: bugs, security issues, weak data models, subtle logic errors. You trust your own judgment over the model's.
• Deep TypeScript expertise across the stack: React/Next.js on the frontend, Node (NestJS or similar) on the backend.
• Strong data-modeling instincts. You design schemas that scale and reason carefully about Postgres, queries, and migrations.
• Shipped product customers paid for and relied on. You can talk specifically about what you built, the tradeoffs you made, and the things that didn't work.

Strong Candidates May Also Have

• Experience building with LLMs and AI agents in production: tool use, orchestration, evals, retrieval.
• Background in compliance, security, audit tooling, or other regulated domains (fintech, healthcare, public sector).
• Time at an early-stage startup or as a founder, where scope was wide and you owned things end to end.
• Experience building for technical buyers (security teams, engineering leaders, CTOs).
• Comfort with infrastructure: CI/CD, observability, background job systems, and cloud (AWS/GCP).

What This Role Is Not

• Narrowly scoped. You'll own whole surfaces, frontend to backend to infra, not a backlog of tickets for one corner of the app.
• Not frontend-only or backend-only. This is genuinely full-stack.
• Not a research role. We ship to customers in weeks.
• Not hands-off. You'll design the system, write the code, and review the PR in the same week.
• Not a place to vibe-code. AI does a lot of the typing, but you own the result and you are expected to catch its mistakes.

Why Comp AI

• Real ownership. What you ship affects the company's numbers, not a sub-team's OKRs.
• Direct access to founders. Decisions happen in conversation.
• AI-native from day zero, in the product and in how we build it.
• A modern stack kept clean, with no legacy debt to fight.
• A category in motion. Compliance is becoming continuous cybersecurity, and you'll help build it.

Compensation and Logistics

Base + equity: $170K - $230K base, plus meaningful equity.
Location: Strongly preferred in-person at our Miami HQ. We'll consider remote for exceptional candidates, and we help with relocation if you want to move.
Visa sponsorship: We don't sponsor visas at this time.

Perks

• Competitive base and meaningful equity.
• Unlimited PTO on top of US federal holidays. Give ample notice and take what you need.
• Quarterly team offsites.
• A strong team to learn from.
