Senior Fullstack Engineer, AI

🚂About Pulley

Pulley's mission is to make it easier for anyone to start a company. We believe that more startups should exist and that founder-led companies are more successful in the long term. With Pulley’s cap table management tools, companies can better understand and optimize their equity for the long term. Starting a company is hard enough. Managing equity shouldn’t be. 

We’re a high-performing team on a mission to redefine how early-stage leaders build and manage their companies in an AI-native world. As AI reshapes how businesses operate, we see a unique opportunity to reimagine equity and business management from the ground up. A brand-new, unsolved challenge that we’re excited to tackle.

Pulley is growing quickly with over 4,000 customers, including startups like Linear, Runway, Fathom, and Roam. Our trajectory is fueled by top investors like Founders Fund, Stripe, General Catalyst, Caffeinated Capital, 8vc, Elad Gil, and other incredible angels. All of our growth has been organic, and we’re expanding the team to meet the growing demand.

We’re looking for passionate, execution-focused self-starters to help us build the next generation of tools for founders.

🌟 About the role

We're looking for a Senior Software Engineer to build the features powering AI capabilities across our core equity platform. You'll own end-to-end delivery across the stack — from backend services that orchestrate agentic workflows and tool integrations, to frontend experiences that bring AI-powered features to life for users. In this role, you'll work closely with product and design to turn ambitious ideas into real product improvements, moving fast while maintaining the quality and scalability our platform demands.

🛠 What You’ll Do

• Build and maintain features end-to-end — from backend services in Go powering agentic workflows and tool integrations, to polished frontend experiences that bring AI capabilities to users
• Implement APIs and service interfaces that connect AI capabilities to our core product reliably and at scale
• Ship complex, multi-step workflow orchestration with strong reliability and observability
• Build frontend features that leverage AI to enhance and simplify equity workflows for users
• Drive performance improvements across the stack — caching, database optimization, and responsive UI
• Mentor junior engineers on best practices and system design

🙌 What You Bring

• 5+ years of full-stack engineering experience building production systems
• Strong proficiency in Go and TypeScript/React, or equivalent backend and frontend experience — ideally balanced across the stack
• Experience integrating LLMs or AI capabilities into production applications
• Familiarity with agentic frameworks and tool orchestration patterns
• Solid API design skills and experience with service-to-service communication
• Experience with PostgreSQL, Redis, and system observability in production
• Clear communicator who can turn product requirements into well-scoped technical plans

Nice to have

• Proficiency in Go and TypeScript/React
• Experience with Temporal or similar workflow orchestration frameworks
• Background in fintech or regulated industries
• Familiarity with AI-powered developer tools like Cursor or Copilot

• Ship It & Iterate - We value people who not only generate ideas but also do the work to bring them to life. Instead of f
