Front End Developer

About Zuma Labs

Zuma Labs is a disruptive technology startup building force multipliers for systemic industries. Our first two products, Venetian and Squawk, target the over-the-counter (OTC) trading markets. We work closely with our customers and count a large publicly traded brokerage among our partners.

Trading technology is an old industry… and we’re here to change that. At Zuma Labs, we value creativity, entrepreneurship, and a genuine passion for problem-solving—but what we’re really looking for are born-and-bred hackers with a healthy disrespect for the status quo.

Role Overview

You will work directly with the founder, experienced brokers, and traders, providing input that immediately impacts the business. You’ll be given broad tasks that support the company’s vision, with incredible autonomy over how to achieve them.

Your work will apply the latest analytical techniques to real-world problems, prioritising working solutions over perfect answers. We want self-starters who are confident but humble, willing to ask questions, seek advice, and iterate fast.

What You’ll Do

• Build and maintain cutting-edge front-end applications in TypeScript and React.
• Collaborate with product, design, and backend teams to ship features that directly affect users and brokers.
• Work in a fast-paced, high-autonomy startup environment where your decisions matter immediately.
• Solve real-world problems with practical solutions, applying creativity and technical skill.
• Develop reusable components, design systems, and contribute to front-end architecture.
• Identify UI/UX and performance bottlenecks and implement improvements.

Required Qualifications & Experience

• Strong TypeScript and React experience (React 16+).
• Proficient in JavaScript ES6+.
• Experience with React Testing frameworks like Jest and Enzyme.
• A keen sense of design and desire to build a better mousetrap.
• General understanding of supporting infrastructure: git, microservices, containers, etc.
• Comfortable working with numbers and data, with or without prior trading/finance experience.

Preferred Qualifications & Experience

• GraphQL / Apollo Client.
• Experience building Single Page Applications (SPAs).
• Reactive mobile UI development experience.
• Experience with Material UI or similar component libraries.
• Familiarity with WebSockets and real-time applications.
• Knowledge of CI/CD pipelines and end-to-end testing frameworks.
• Exposure to browser APIs and UX/UI design principles.

Why Zuma Labs?

• Work in a high-impact startup environment where your work immediately affects the business.
• Collaborate directly with founders, traders, and product experts.
• Apply your technical skills to real-world problems that go beyond theoretical exercises.
• Grow as a developer and problem solver in a culture that encourages creativity, ownership, and experimentation.
