Associate Solutions Engineer Jobs in Long Beach, CA

D3 is building the world's first purpose-built blockchain for DomainFi - bringing domain tokenization and DeFi primitives to a massive, rapidly growing $350B+ real-world asset class. We're revolutionizing how existing and future domain names are owned, traded, and leveraged in the digital economy.

Our team is stacked with industry veterans who have spent the last three decades shaping the internet, from pioneering domain name monetization to architecting key internet protocols to launching and running major TLDs like .xyz, .inc, .tv, and .link.

We recently closed a $25M Series A led by Paradigm, fueling our mission to bring domains fully on-chain and unlock new financial possibilities for one of the internet's most valuable asset classes.

We're based in Los Angeles, with team members all over the world. We're looking for driven, talented builders to help build a trillion-dollar DomainFi economy.

We're looking for an Associate Solutions Engineer to be the technical glue between our Business Development team and our registrar and enterprise customers. This is a hands-on, customer-facing role for someone early in their career who's hungry to learn the domain industry, Web3, and how to scale technical partnerships at a Series A startup.

You'll be a sharp, curious operator who can pick up complex technical concepts quickly, write clear documentation, build small sample integrations, coordinate moving pieces across teams, and use modern tools - including AI - to multiply your output. Think of this as a junior solutions and developer relations role with a project management spine: part technical writer, part customer liaison, part coordinator.

You'll work closely with our BD, Product, and Engineering teams. If you're someone who learns fast, communicates clearly, and wants to grow into a senior solutions or technical partnerships role at a company defining a new category, this is for you.

Pre-Sales Technical Support

• Sit alongside BD during conversations with registrars and domain industry partners
• Explain how our platform, APIs, and integration models work in plain language
• Capture customer technical questions, requirements, and constraints, and route them to the right internal owners
• Help shape solution approaches that align customer needs with platform capabilities
• Build trust as a responsive, organized technical point of contact

Integration Project Management

• Track integration timelines, milestones, and blockers across deals from signed contract to go-live
• Coordinate Product, Engineering, Legal, and Operations on what each customer needs and when
• Surface risks early and drive cross-functional resolution
• Keep customers informed with clear status updates

Documentation & Sample Code

• Write and maintain customer-facing integration guides, API docs, FAQs, and "how-to" content
• Build small sample scripts, code snippets, and demos that help customers understand and adopt our APIs
• Produce short walkthrough videos and tutorials for common integration patterns
• Continuously improve documentation based on real customer feedback

Internal Leverage & Tooling

• Use AI tools (Claude, Cursor, ChatGPT, etc.) to accelerate documentation, code samples, customer research, and internal workflows
• Build lightweight internal tools that make the solutions function more efficient
• Bring customer insights back to Product and Engineering to improve our APIs and developer experience

Required

• 2+ years of experience in a technical, customer-facing, or developer-adjacent role (solutions engineering, sales engineering, technical support, developer relations, technical PM, integrations, or similar)
• Strong written communication: you can explain technical concepts clearly to both engineers and non-technical stakeholders
• Comfortable reading code and writing small scripts or sample integrations in at least one language (Python, JavaScript, Go, or similar)
• Demonstrated fluency using AI tools as part of your daily workflow (we'll ask about how you actually use them)
• Organized, self-directed, and comfortable owning timelines and follow-through without heavy oversight
• Genuine curiosity about the domain industry, internet infrastructure, and Web3

Bonus

• Exposure to the domain name ecosystem (registrars, DNS, ICANN) or internet infrastructure
• Familiarity with REST APIs, webhooks, or distributed systems
• Hands-on experience or personal projects in Web3, blockchain, or tokenization
• Experience with technical documentation tools (Mintlify, ReadMe, GitBook, etc.)
• Open source contributions, developer community involvement, or a portfolio of small projects that show how you think and build

The kind of person who'll thrive here

• Hungry, fast-moving, and excited to be on the ground floor of a category-defining company
• Treats AI tools as a force multiplier, not a crutch
• Open to relocating to or already in Los Angeles
• Values growth, learning, and impact over a senior title on day one

Ground-Floor Growth, Learning, and Impact: Every move you make matters. You'll sharpen your skills, expand your expertise, and shape the foundation of something groundbreaking. Almost everything we're building today is "zero-to-one."

Strong, Proven Leadership: You'll work alongside industry visionaries who have been there, done that, and are ready to do it again - only bigger. You'll get mentorship from operators who have launched and scaled some of the most important TLDs on the internet.

Unique Market Positioning: We're pioneering at the intersection of internet infrastructure, real-world assets, and blockchain. If you want to push boundaries and help define a new category, D3 is the place.
