Full Stack Engineer

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

As a Full Stack Engineer at Pasito, you’ll build the product experiences and technical systems that help employees understand, elect, and use their benefits. You’ll work across frontend, backend, infrastructure, and AI-powered workflows to deliver polished, scalable web applications that improve health and financial outcomes for millions of families.

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

You’re an engineer with strong product instincts who enjoys prototyping, experimenting, and iterating quickly. You understand that great products are not invented in one pass, but discovered through relentless iteration, customer feedback, and thoughtful execution.

What You’ll Do

• Build full-stack product experiences

• Design, build, and ship scalable web applications across the frontend and backend, with a focus on usability, reliability, and long-term maintainability.

• Deliver polished frontend experiences

• Create delightful, high-quality user interfaces using modern frontend frameworks like Next.js. You may not be a designer, but you enjoy collaborating closely with design and care deeply about the details that make products feel intuitive and trustworthy.

• Own backend systems and APIs

• Build and maintain backend services, APIs, data models, and integrations that power Pasito’s platform, with attention to correctness, scalability, observability, and clean architecture.

• Integrate AI into real products

• Work with AI and LLM-powered systems, including models like ChatGPT and Claude, to help bring intelligent benefits guidance into core user workflows.

• Collaborate cross-functionally

• Work closely with Product, Design, Sales, Client Success, and Operations teams to understand customer needs and translate them into durable technical solutions.

• Continuously improve systems

• Refactor thoughtfully, reduce technical debt, improve testing and reliability, and help define what “great” looks like as the platform and team scale.
