Job description

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 elite 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. With a proven track record of innovation and success, we’re now redefining what’s possible in the domain space.

We recently closed a $25M Series A led by Paradigm - one of the best investors in the industry. This will help fuel 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. Join us!

Job Overview

We are seeking a Partnership Engineer to support strategic partners across the full customer lifecycle — from pre‑sales technical engagement through post‑signing delivery and activation. This is an individual contributor role that sits at the intersection of business development, product, and engineering, and is critical to ensuring partners can successfully integrate with and scale on the D3 platform.

This is a highly collaborative, partner‑facing role for someone who understands complex technical systems, can translate between commercial and engineering stakeholders, and thrives in environments where clarity, coordination, and follow‑through matter. You will work hands‑on with partners and internal teams to drive successful outcomes across pre‑sales and delivery.

Key Responsibilities

1. Pre‑Sales Technical Support

• Support the Business Development team during pre‑sales engagements with registrars and other domain industry partners
• Act as the primary technical point of contact during discovery, evaluation, and solution discussions
• Explain platform architecture, integration models, and workflows to partner technical teams
• Assess partner technical readiness, constraints, and integration requirements
• Help shape solution approaches that align partner needs with platform capabilities

2. Partner Delivery & Integration Support

• Provide continuity from pre‑sales through post‑signing delivery and go‑live
• Coordinate closely with Product, Engineering, Legal, and Operations teams to align on integration scope, timelines, and requirements
• Translate partner requirements into clear internal inputs and next steps
• Support technical onboarding, integration milestones, and go‑live readiness
• Identify and surface integration risks, issues, and blockers and help drive resolution through cross‑functional coordination
• Use data and metrics to monitor partner onboarding progress, integration health, and early activation performance

3. Partner Enablement & Ongoing Support

• Support partner activation and early scaling on the platform
• Ensure partners understand platform capabilities, workflows, and best practices
• Provide technical guidance to help partners operationalize and monetize their integrations
• Serve as a trusted technical contact for partners during early lifecycle phases
• Gather partner feedback on integration experience, tooling, and documentation
• Provide structured input to Product and Engineering teams to improve APIs, workflows, and partner enablement
• Contribute to the development of repeatable integration documentation and playbooks
• Create partner‑facing technical documentation and integration guidance including “go‑to” guides and videos.

Qualifications

Required

• 5+ years of experience in solutions engineering, sales engineering, technical partnerships, or similar partner‑facing technical roles
• Experience supporting external partners through complex integrations or platform onboarding; triage and resolve technical issues to reduce impact on product and engineering teams
• Strong ability to understand and explain technical systems and architectures without owning hands‑on development
• Proven experience working cross‑functionally with product, engineering, and business teams
• Excellent communication skills with both technical and non‑technical stakeholders

Preferred

• Experience in the domain name ecosystem, internet infrastructure, or adjacent industries
• Familiarity with APIs, platform integrations, and distributed systems (conceptual understanding)
• Exposure to Web3, blockchain, or tokenization concepts (or strong willingness to learn)
• Experience operating in regulated or compliance‑driven environments
