Junior Web3 Startup information

What is a junior web3 startup?

A Junior Web3 Startup is an early-stage company focused on building products or services using Web3 technologies, which include blockchain, decentralized applications (dApps), cryptocurrencies, and smart contracts. These startups are usually in their initial phases of development, often working with small teams to innovate in areas like decentralized finance (DeFi), NFTs, or blockchain infrastructure. The 'junior' designation typically refers to the company's age and experience in the market, rather than the skill level of its employees. Working at a junior Web3 startup can offer opportunities to learn, experiment, and grow with emerging technologies. These startups often seek team members who are adaptable, motivated, and willing to take on a variety of roles.

What are some common challenges faced by team members in a junior role at a web3 startup?

Team members in a junior role at a Web3 startup often navigate a rapidly evolving technology landscape, which can present challenges such as staying up-to-date with new blockchain protocols and tools. The fast-paced nature of startups also means that responsibilities can shift quickly, requiring adaptability and a proactive approach to problem-solving. Additionally, juniors frequently collaborate with cross-functional teams, including developers, product managers, and community managers, which helps them gain a broad understanding but can be challenging when learning to communicate technical concepts. However, this dynamic environment provides valuable growth opportunities and a chance to make a direct impact early in your career.

What are the key skills and qualifications needed to thrive as a junior web3 startup professional, and why are they important?

To thrive as a Junior Web3 Startup Professional, you need a solid grasp of blockchain fundamentals, smart contract development, and basic programming skills, often supported by a degree in computer science or related fields. Familiarity with tools like Solidity, Ethereum, decentralized application (dApp) frameworks, and version control systems such as Git is typically required. Strong problem-solving abilities, adaptability, and effective communication help individuals excel in the fast-evolving and collaborative Web3 environment. These skills enable professionals to contribute to innovative projects, quickly learn emerging technologies, and work effectively within dynamic startup teams.

Job description

About D3

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.

About the Role

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.

What You'll Do

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
What We're Looking For

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
Why D3, Why Now?

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.
