Job Details

Location: Full Time, San Francisco / Remote Friendly.

We're a team of innovators, problem-solvers, and dreamers. At Diagon, we're on a mission to equip the factories of the future. As the premier manufacturing equipment marketplace, we simplify how companies buy and sell battery manufacturing equipment for cell production and energy storage solutions. Our platform connects buyers and sellers, offering a seamless experience with exclusive listings, financing options, shipping support, and access to high-quality equipment—both new and used.

Diagon isn't just a marketplace; we're the first platform providing direct access to battery manufacturing equipment listings and transparent pricing. Our mission is to make equipment sourcing easy, accessible, and tailored to the unique needs of battery production. Join us as we revolutionize the industry and contribute to the future of clean energy.

As our Full Stack Engineer, you'll play a pivotal role in developing Diagon's core platform, helping build a seamless, AI-powered marketplace for manufacturing equipment.

We're looking for someone who is:

1. Deep in the technical weeds—shipping production-ready code, making architectural decisions, and optimizing our stack.
2. Product-minded—thinking beyond code to how users interact with what you build, optimizing for speed, usability, and efficiency.
3. AI-curious—excited about working with AI-powered tools and automation to enhance marketplace efficiency and user experience.
4. Startup-driven—thrives in fast-paced environments, loves solving zero-to-one problems, and is comfortable wearing multiple hats.
5. A systems thinker—not just writing code, but designing the infrastructure and workflows that power a frictionless marketplace.

Responsibilities include:

1. Develop key features for the Diagon Marketplace, focusing on both front-end and back-end development.
2. Collaborate with cross-functional teams, including product, design, and operations, to deliver user-centric solutions.
3. Optimize and integrate AI-powered tools to improve product listings and marketplace efficiency.
4. Take ownership of technical decisions, balancing performance, usability, and long-term maintainability.
5. Work across the stack, from interactive UI components (React/Next.js) to server-side logic (Server Actions, PostgreSQL, Prisma).
6. Stay ahead of emerging technology trends, continuously refining our stack.

Qualifications:

1. Strong technical foundation with experience shipping production-ready code.
2. Experience with marketplaces, e-commerce, or B2B platforms.
3. Ability to balance speed and quality, knowing when to build for scale and when to iterate quickly.
4. Passion for working in AI-driven products, automation, or workflow optimization.

We offer:

1. Competitive salary, equity, and benefits.
2. The opportunity to work on industry-changing technology.
3. A collaborative, fast-moving environment where you'll make a direct impact.
4. A remote-friendly culture, with Bay Area presence preferred but not required.
