Backed by Ribbit Capital, Franklin Templeton, NYCA, First Round, and Lightspeed Faction, with $23.6M raised in 2025. Trusted by more than 40,000 clients including global leaders such as MoneyGram, WireX, Toku, and more, Crossmint provides embedded smart wallets, on/offramps, cross-chain stablecoin orchestration, tokenization, and other blockchain primitives through simple, developer-friendly APIs that integrate in minutes and scale to millions of users.

Crossmint also powers the Republic of the Marshall Islands' first digital UBI program, backs MoneyGram's new stablecoin cross-border experience launching in LATAM, and recently partnered with WireX to expand multichain stablecoin payment infrastructure to non-EVM networks like Stellar.

Type of employment

Full-time

Seniority

4+ years of experience in developer relations, developer advocacy, solutions engineering, or a similar technical role.

About The Role

We are seeking a Senior Developer Relations Engineer who will bridge the gap between Crossmint's engineering team and the global developer community. You will combine strong technical expertise with hands-on building — shipping demo applications, writing production-grade code, QA-ing developer journeys and product integrations, improving documentation, and creating internal tools and automations that raise the bar for how we support developers at scale.

This is not a purely outward-facing role. A significant part of your work will happen in the codebase: building and maintaining reference apps and starter kits, stress-testing integration flows from a developer's perspective, identifying friction before it reaches the community, and making sure our APIs, SDKs, and onboarding experiences are as polished as the products they represent.

You will also engage externally — through content, community, workshops, and direct developer support — but the foundation of your impact will be deep technical ownership of the developer experience end to end. You will play a highly cross-functional role driving adoption, influencing product direction through community insights, and ensuring developers have a world-class experience building with Crossmint.

Responsibilities

Developer Advocacy & Technical Enablement

• Serve as a technical expert and trusted partner for developers building with Crossmint.

• Build and maintain sample applications, starter kits, SDK examples, and reference architectures.

• Provide hands-on technical guidance to developers integrating Crossmint APIs and infrastructure.

• Support strategic partners and high-impact integrations when needed.

Technical Content & Education

• Create in-depth technical content including tutorials, walkthroughs, blog posts, demo apps, videos, and documentation improvements.

• Lead workshops, hackathons, webinars, and live coding sessions showcasing real-world use cases.

• Ensure Crossmint’s documentation, code samples, and onboarding flows meet high standards of clarity and developer usability.

Community Engagement

• Actively participate in developer communities across Discord, GitHub, X, forums, and events.

• Answer technical questions, troubleshoot issues, and proactively identify friction points.

• Build relationships with ecosystem builders, startups, and partners.

Product Feedback & Cross-Functional Collaboration

• Partner closely with product and engineering teams to communicate developer feedback, common pain points, and feature requests.

• Contribute to API design discussions from a developer-experience perspective.

• Track adoption metrics, developer engagement, and content performance to inform strategy.
