Full Stack Engineer with AI experience

About Pasito

Pasito is the AI workspace for employee benefits.

We’re rethinking how group insurance and benefits are underwritten, delivered, used and measured - by the people who design them and the people who depend on them. Instead of static PDFs, disconnected systems, and manual workflows, Pasito brings plan design, payroll and benefits data, claims, and financial context into a single, AI‑native workspace that helps benefits actually work for the 178 million Americans who depend on this system.

We don’t build for brokers, carriers and employers - we build with them. That collaboration shows up in everything we ship: AI agents that extract and structure plan data, tools that turn complexity into clarity for employees, and workflows that save carriers and consultants hundreds of hours per case.

Today, Pasito supports many of the largest insurance carriers and brokers in the U.S. We’re backed by Y Combinator and Core Innovation Capital, and we’re growing quickly. We ship fast, iterate relentlessly, and care deeply about building systems that are accurate, scalable, and human.

If you’re excited to work alongside exceptional operators and engineers, and apply AI in a legacy industry where precision and trust matter, Pasito is the place for you.

The Role

We’re looking for a Full Stack Software Engineer with AI experience to help build and scale the core systems that power Pasito’s AI workspace.

This role is for an engineer who enjoys working across backend systems, data pipelines, and user-facing features - and who is excited about building production-grade AI workflows into real products. You’ll own features end-to-end, from system design and APIs to AI integrations and product surfaces.

As an early member of the engineering team, you’ll have real ownership and influence: shaping architecture, defining standards, and building systems that carriers, brokers, and employers rely on every day.

What You’ll Do

Develop AI-native workflows
Build and integrate AI and LLM-powered systems for extracting, structuring, and reasoning over complex benefits data.

Own backend and data-heavy systems
Design scalable services, data models, and pipelines that support accuracy, performance, and long-term maintainability.

Build end-to-end product systems
Design, implement, and ship features across backend services, APIs, data layers, and frontend integrations that power Pasito’s platform.

Collaborate cross-functionally
Work closely with Product, Design, Sales, and Client teams to understand customer workflows and translate them into durable technical solutions.

Continuously improve systems
Refine existing architecture, reduce operational complexity, and help define what “great” looks like as the platform scales.

Who You Are

• A full stack engineer with 3+ years of experience building complex web applications 
• Comfortable owning backend systems and APIs, while collaborating closely on frontend experiences
• Experienced integrating AI / LLM-powered systems into real products
• Curious, adaptable, and energized by working in fast-moving, ambiguous environments
• A collaborative partner to product managers, designers, and other engineers

Technical Experience We’re Excited About

• Strong experience with TypeScript across frontend and backend (Node.js)
• Experience building and operating backend services, APIs, and data pipelines
• Hands-on experience working with AI / LLMs (e.g., ChatGPT, Claude) in production systems
• Familiarity with modern frontend frameworks such as Next.js
• Experience with testing, observability, and maintaining production systems
• Experience integrating with third-party systems or complex data sources

Experience in insurance, healthcare, or financial services is a plus, but not required.

What’s In It For You

• Meaningful ownership: Build foundational systems used by carriers, brokers, employers, and employees at scale
• Real impact: Your work directly improves how people understand and use their benefits
• Growth: Join early and grow with the company as we scale our product, team, and distribution
• Competitive compensation: Salary, meaningful equity, and full benefits: medical, dental, vision, 401(k) with match, life insurance, and flexible PTO
• Remote‑first: Work from anywhere in the U.S. with a highly collaborative team
