Senior Backend Engineer, Core Product

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. Pulley is growing quickly with over 8,000 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‑starrters to help us build the next generation of tools for founders.

We're looking for a Senior Backend Engineer to build and ship the systems that power Pulley's core equity platform. You'll own end‑to‑end delivery of complex features — working across data models, APIs, and backend services to ship high‑impact improvements for startup founders. In this role, you'll work closely with product, design, and other engineers to turn business problems into clean, reliable software.

You'll help modernize our platform, improve system performance, and ensure our backend is robust and maintainable as we scale. This role is ideal for someone who thrives in ambiguity, moves fast, and wants to work on systems that truly power company‑building at scale.

• Mentor junior engineers on backend best practices and system design

• 5+ years of backend engineering experience building production systems
• Strong proficiency in Go
• Solid understanding of database design, data modeling, and persistence best practices
• Experience designing APIs and working closely with front‑end teams
• Strong product sense and ability to translate complex requirements into clean, maintainable systems
• A collaborative mindset — you work well with product, design, and other engineers

• Experience in fintech or other high‑trust domains
• Familiarity with equity management tools or legaltech systems

• We've moved beyond early‑stage uncertainty - Our product has traction and we're building on a solid foundation, but we're still early enough in our journey where your work will directly shape the company's trajectory as we scale.
• Make it easier for anyone to start a company - Founders turn bold ideas into reality — building things that might not exist otherwise. Starting a company is hard enough. Managing equity shouldn't be. Pulley exists to make equity management simpler, smarter, and more accessible for founders from day one.
• Work with a high‑performing and passionate team - We value the concept of stunning colleagues and we're thoughtful about creating a team that is excited about building a great company together. Here are some traits that enable our team members to thrive:
