Senior Frontend Engineer

About the Role

We're working with a company building secure infrastructure for enterprise blockchain and cryptographic systems, including multi-party computation (MPC) technology. The team is expanding its frontend capabilities and is actively moving toward agentic and AI-assisted engineering workflows.

The right person will step into a lean, self-directed engineering group and take real ownership over how the frontend is built, structured, and maintained across several products. One of the current priorities is connecting the company's digital-asset platform with a US banking partner, which involves building tokenized-dollar features and weaving the product experience into the bank's existing systems.

What We're Looking For
 

Core Technical Background

• Solid, senior-to-expert-level commercial experience in frontend engineering.
• Deep expertise in TypeScript/JavaScript and React.
• Strong Next.js background and a real understanding of modern frontend architecture.
• Hands-on experience with agentic or AI-assisted development that goes beyond simple code generation or casual "vibe coding."
• Practical testing experience: Playwright for end-to-end, and Jest, Vitest, or similar for unit/component testing.
• Comfortable with GitHub, GitHub Actions, and modern CI/CD practices.

• A security-minded approach to engineering, especially for sensitive or regulated products.

   

Nice-to-Haves

• Familiarity with Web3/blockchain concepts and associated security considerations.
• Background in FinTech or financial services products.
• Experience deploying on Vercel.
• Some exposure to TanStack Start.
• Comfort with AWS and containerized, cloud-agnostic setups.

• Time spent in regulated environments or those aligned with SOC 2 standards.

   

Domain Exposure

• Web3/blockchain knowledge is a strong plus but not mandatory if you show genuine curiosity and can pick up the domain quickly.
• FinTech or financial-services experience works well as an alternative or complementary background.
• Comfortable working in small, fast-paced product teams where engineers have a lot of autonomy.
  
   

What You'll Do

Frontend Development

• Build senior-level features across the product lineup.
• Write maintainable, scalable interface code in TypeScript, React, and Next.js.
• Turn loosely defined or high-level requirements into working solutions without needing fully detailed tickets.
• Weigh in on architectural and technical design choices for the frontend.
   

AI-Assisted / Agentic Development

• Contribute to building out mature practices and guardrails around agentic and AI-assisted engineering.
• Apply AI tooling to speed up delivery while keeping code quality, maintainability, security, and test coverage intact.
• Help introduce sensible checks and balances as AI-assisted practices spread across both frontend and backend teams.
   

Quality, Testing, and Security

• Thoroughly test your own code, covering both unit/component and end-to-end scenarios.
• Partner closely with QA throughout releases and support strong engineering practices overall.
• Stay alert to Web3-specific and general application-security risks, particularly those relevant to digital-asset products.
   

Technical Mentorship and Product Thinking

• Offer technical guidance and mentoring to a Cayman-based frontend colleague, without formal management authority.
• Bring a product-oriented mindset and make sound delivery calls when requirements aren't fully fleshed out.
• Independently dig into unfamiliar product or Web3 topics and come back with workable solutions to ambiguous problems.
