About The Role

As a Customer Success Engineer / Solutions Architect at Crossmint, you will work directly with our most important enterprise and high-growth customers to ensure they successfully design, launch, and scale production applications on top of Crossmint’s infrastructure.

This is a deeply technical, customer-facing role that blends solution design, hands-on implementation, and strategic advisory. You will act as a trusted technical partner to customer engineering teams while collaborating closely with Product, Platform, and Go-To-Market teams internally.

You will operate across pre-launch, launch, and post-launch phases, helping customers move from concept to production and beyond.

What You Will Do

• Own technical success for key customers: act as the primary technical point of contact for enterprise and strategic accounts.
• Design end to end solutions: architect integrations using Crossmint’s APIs, wallets, payments, tokenization, and compliance primitives.
• Build and prototype: develop proofs of concept, middleware, scripts, or lightweight applications to accelerate customer adoption.
• Guide production deployments: support customers through go-live, scaling, observability, and performance tuning.
• Translate customer needs into product insight: surface patterns, gaps, and opportunities to Product and Engineering teams.
• Serve as a technical advisor: lead architecture reviews, implementation walkthroughs, and best practice sessions with customer teams.
• Automate and scale: build internal tools, scripts, or workflows using automation and AI to improve delivery velocity and reliability.
• Champion customer health: proactively identify risks, unblock issues, and drive long-term customer success and expansion.
• Operate with high ownership: manage complex, high-stakes engagements in fast-moving and ambiguous environments.

About You

You are a senior engineer who enjoys working directly with customers and solving real-world problems. You are comfortable owning outcomes, not just delivering code.

You bring:

• 6+ years of experience in software engineering, solutions engineering, forward deployed engineering, or similar roles.
• Strong experience with APIs and integrations, including REST APIs, authentication flows, webhooks, and SDKs.
• Proficiency in TypeScript or Python, with working knowledge of frontend frameworks such as React.
• Hands-on web3 experience, including wallets, tokenization, or blockchain-based systems.
• Experience writing and deploying smart contracts, such as ERC721, ERC1155, ERC20, or similar standards.
