We are hiring for an innovative crypto wallet and payment network startup seeking a Tech Lead to spearhead the development of a
merchant portal,
SDK, and integration of our
proprietary payment method for a mobile-first app. You will drive the technical strategy to position our payment method as a seamless, quick, reliable, and scalable option alongside Alipay, WeChat Pay, PayMe, and others at retail POS and digital locations. You will also oversee the integration of a white-label or plug-and-play e-commerce solution into the mobile app as a secondary focus. The CTO will lead blockchain-related components, so crypto experience is not required but knowledge is a plus. Mobile development experience is appreciated but not essential, given the mobile-first approach. This role demands hands-on leadership to deliver secure, developer-friendly solutions in a fast-paced environment.
Responsibilities
- Define and execute the technical vision for a merchant portal, SDK, and integration of our proprietary payment method within a mobile-first app, ensuring it is seamless, quick, reliable, and scalable at retail POS and digital locations.
- Lead the design and development of a merchant portal to support vendor onboarding, catalog management, transaction tracking, and payout workflows, optimized for mobile interfaces.
- Architect a developer-friendly SDK to enable third-party integrations with our payment method and wallet app.
- Oversee integration of our proprietary payment method into retail POS terminals and digital platforms, ensuring it operates on par with Alipay, WeChat Pay, PayMe, and other leading payment solutions.
- Select and integrate a white-label or plug-and-play e-commerce solution (e.g., Shopify, OpenCart) into the mobile app, ensuring alignment with the proprietary payment system.
- Design secure, scalable APIs (REST, GraphQL) and backend systems to support merchant and payment workflows.
- Collaborate with external stakeholders (e.g., merchants, POS vendors, payment ecosystem partners) to align technical solutions with business requirements.
- Manage and mentor a cross-functional team of engineers (full-stack, backend, mobile) to deliver high-quality, maintainable codebases.
- Ensure robust security, scalability, and performance of all systems, adhering to financial compliance standards (e.g., AML/KYC).
- Drive DevOps practices, including CI/CD pipelines, serverless infrastructure, and cloud-based deployments (e.g., AWS).
Qualifications
- 5+ years of software engineering experience, with 2+ years in a tech lead or senior engineering role.
- Proven experience building merchant portals or vendor-facing platforms, including workflows for onboarding, catalog management, or payouts.
- Expertise in API design (REST, GraphQL) and SDK development for third-party integrations.
- Hands-on experience integrating payment systems into retail POS terminals or digital platforms, with a focus on seamless, reliable, and scalable solutions.
- Strong proficiency in modern tech stacks (e.g., Node.js, Typescript, React, Next.js, NestJS) and cloud platforms (e.g., AWS Lambda, API Gateway, S3).
- Experience leading distributed teams in fintech, e-commerce, or related fields.
- Ability to work on-site or hybrid in Hong Kong or Singapore, with flexibility for periodic travel.
Preferred Skills
- Experience integrating white-label e-commerce solutions (e.g., Shopify, OpenCart) or payment systems into retail POS or digital platforms.
- Familiarity with mobile-first development (e.g., React Native, responsive design) for merchant-facing applications, though not essential.
- Proficiency in serverless architecture, event-driven systems, or infrastructure tools (e.g., Serverless Framework, Terraform).
- Knowledge of crypto payment systems, DeFi, or blockchain-based technologies (e.g., wallets), though not required as the CTO leads blockchain components.
- Strong stakeholder engagement and communication skills to align with merchants, POS vendors, and business teams.
