Our Ethos

Operating at the epicenter of stablecoin innovation means moving fast and thinking globally. Our team reflects the diverse, international audiences we serve.

• Collaborate with enterprise customers, fintechs, exchanges, and ecosystem partners to ensure successful implementation.

• Provide hands-on guidance during integration, working closely with developers, DevOps teams, and security stakeholders.

• Diagnose and resolve API, blockchain, and infrastructure-level issues, escalating to engineering when needed.

• Advocate for best practices around operational security, key management, transaction monitoring, and compliance-friendly architecture.

• Gather customer insights to influence product roadmaps and feature prioritization.

• Partner with Sales, Product, and Engineering to deliver scalable and repeatable technical solutions.

• Contribute to technical documentation, integration guides, and internal playbooks.

What we're looking for

• 3–7+ years of experience in Solutions Engineering, Sales Engineering, Technical Consulting, or similar roles.

• Strong understanding of blockchain fundamentals, distributed systems, and crypto payment flows.

• Experience working with REST APIs, Webhooks, SDKs, and backend integration patterns.

• Hands-on coding ability in at least one language (e.g., JavaScript/TypeScript, Python, Go, Rust).

• Ability to simplify complex technical concepts for both technical and non-technical audiences.

• Excellent communication, client-facing, and project management skills.

Nice to haves, but not mandatory

• Experience with stablecoins, custody systems, digital wallets, or payment rails.

• Familiarity with blockchain protocols such as Ethereum, Solana, or Layer-2 scaling networks.

• Knowledge of compliance-relevant concepts such as KYC/AML workflows, transaction screening, or on-chain analytics.
