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.
Comfort operating in customer-facing environments, including working directly with engineers, product leaders, and executives.
Strong communication skills, able to explain complex technical concepts clearly.
High autonomy and adaptability, with the ability to navigate ambiguity and prioritize effectively.
A strong interest in programmable wallets, stablecoins, and agent-driven commerce.

Strong Plus If You Have

Prior experience as a Solutions Architect, Customer Success Engineer, Partner Engineer, or Forward Deployed Engineer.
Experience supporting enterprise or regulated customers in fintech, crypto, or payments.
Familiarity with observability tools such as Datadog or Sentry.
Experience contributing to SDKs, middleware, or developer platforms.
Experience using automation and AI tools such as scripting, Zapier, or AI copilots to scale delivery.
Contributions to web3 open-source projects or production crypto systems.
