About the Role
At Ceryneian, we’re building a next-generation, research-driven algorithmic trading platform aimed at democratizing access to hedge fund-grade financial analytics. Headquartered in California, Ceryneian is a fintech innovation company dedicated to empowering traders with sophisticated yet accessible tools for quantitative research, strategy development, and execution.
Our flagship platform is currently under development. As our Frontend / Full Stack Engineer, you’ll lead the creation of a stunning, intuitive user experience—spanning our landing page, drag-and-drop strategy builder, trading dashboards, and internal tools. You’ll collaborate closely with design, backend, and DevOps teams to build high-performance, secure, and scalable customer-facing applications. This role is central to delivering the reliability, flexibility, and performance our users will rely on in fast-moving financial markets.

We are a remote-first team and are open to hiring exceptional candidates globally.

Core Tasks
• Design, build, and deploy customer-facing interfaces, including the strategy builder, dashboards, and marketplace.
• Implement reusable UI components based on Figma designs; integrate charting tools like TradingView or Highcharts.
• Own the frontend development pipeline, including prototyping, implementation, testing, and responsiveness.
• Implement secure authentication and user management (OAuth2, JWT, multi-role access).
• Build real-time web experiences using WebSockets, REST, and client-server integrations.
• Collaborate with backend and DevOps teams to streamline data flow and deployment workflows.

Top Technical Competencies
• Strong foundation in HTML/CSS, JavaScript/TypeScript.
• Proficiency in modern frontend frameworks such as React (Next.js), Svelte, Angular, Vue, or Phoenix.
• Experience with OAuth2 and secure authentication workflows.
• Familiarity with server-side rendering (SSR) and modern state management (Zustand, Redux, MobX).
• Integration experience with charting libraries such as TradingView, Recharts, or Highcharts.
• Deployment experience using platforms like Vercel, Heroku, GCP, or AWS.
• Working knowledge of WebSockets, REST APIs, and data streaming models.
• 0–3 years of frontend development experience.

Bonus Competencies
• Familiarity with Supabase, PostgreSQL, Firebase, or MongoDB.
• Understanding of microfrontend architectures or API Gateway patterns.
• Experience with WebAssembly and real-time trading interfaces.
• Exposure to fintech platforms or trading systems.
• Background from Tier-I or Tier-II institutions with strong computer science fundamentals, a passion for scalable system design, and a drive to build cutting-edge fintech infrastructure.

Ideal Candidate
You’re a design-minded full stack engineer who builds fast, clean, and modular frontend systems. You thrive on making complex interfaces intuitive—turning strategy logic into drag-and-drop workflows—and can ship high-performance components that integrate seamlessly with real-time APIs. You value design systems, scalable frontends, and cross-functional collaboration.

What We Offer
• Opportunity to shape the product interface of a next-gen fintech startup.
• A collaborative, technically driven culture.
