About Squads

Squads is a financial technology company building products and APIs for the stablecoin economy. We build on open infrastructure, global money and internet capital markets to deliver better financial services to every business, individual and developer.

Our Products

Squads Multisig: The premier multisig platform for Solana.
Altitude: A global business account to save, earn and move money.
Fuse: A personal finance app for stablecoins and tokenized assets.

These three products are powered by our stablecoin infrastructure and developer platform: Grid.

Our investors include Haun Ventures, Multicoin Capital, Electric Capital, Coinbase Ventures, Toly, Mert, and others.

Squads Multisig is our self-custodial platform for securing and managing assets on Solana. It’s built for Solana treasuries, program upgrades, validator operations and token management.

Trusted by 450+ teams to secure over $10 billion in value, Squads Multisig is used by almost every team in the Solana ecosystem, including leading protocols such as Jito, Jupiter, Drift, Kamino, and Helius.

About the Role

As a Senior Frontend Engineer, you’ll join a high-caliber team at the intersection of design and engineering. You will own the development of intuitive, performant, and secure web applications built on Squads Protocol.

You’ll work across product, design, and engineering to shape user experiences from ideation to production, with full ownership of feature development. If you're a multidisciplinary builder who obsesses over elegant interfaces and clean code—this is your playground.

This role is ideal for someone who wants autonomy, thrives in rapidly evolving environments and wants to make an outsized impact in a fast-moving Web3 environment.

Rapidly implement functional, responsive UI components from designs, with attention to performance and accessibility
Lead frontend architecture and help evolve our design system
Collaborate with product and engineering teams to ship features from concept to launch
Maintain and improve the application codebase with scalable, well-documented, and tested code
Uphold high coding standards, contribute to code reviews, and mentor junior engineers

Qualifications

Core Expertise:

Demonstrated expertise (5+ years) in building and delivering high-performance, visually refined web applications, with a deep understanding of browser fundamentals, modern JavaScript (ES6+), and advanced TypeScript features.5
Strong proficiency in React, TypeScript, and modern frontend development best practices with Clean, modular, async-safe code
You approach product engineering with a user-first mindset, proactively shaping features and interfaces to deliver intuitive, delightful, and accessible experiences.
Solid grasp of systems design, debugging, and application performance
Experience working with REST APIs and backend systems, gPRC and WebSocket APIs
Strong communication skills and comfort with ambiguity—able to propose and lead solutions proactively

Our Values

Kindness Matters. We show kindness and respect to all users, customers, and team members in every interaction (internal and external). Being kind compounds and strengthens our relationships.
Craftsmanship Excellence. We deeply care about the quality of everything we create. Every contribution, regardless of size, must meet our high standards for excellence.
Radical Transparency. We communicate openly and honestly with each other. Respectful candor is valued over comfortable silence, as we can't afford to miss insights due to fear of speaking up.
Bias for Action. We believe action produces information. At no more than 20% completion of a project we must have a working prototype to test and iterate on.
Speed with Purpose. We move with urgency and focus. Slow and expensive usually go together. Good, fast, and cheap outcomes are perfectly achievable through disciplined execution.
Professional Integrity. We never speak negatively about competitors, partners, vendors, or others. Such behavior reflects insecurity and provides no value.
Creative Problem-Solving. We value innovative thinking that challenges conventions. The best solution aligns with the task at hand, not necessarily with how things have always been done.
Team Over Ego. We share both successes and failures collectively. No individual's ego should surpass our commitment to the product and its impact.
Results Over Hierarchy. We do not care about titles in this company. No politics, no hierarchy. All we care about is winning together.

If you’re excited to help businesses access modern money rails and believe that stablecoins will democratize finance, we’d love to talk. Reach out to us

🎯 Who is this job for?

This role is best suited for a Senior Frontend Engineer with 5+ years of experience building high-performance web applications and deep expertise in React, TypeScript, and modern frontend architecture. The candidate should be comfortable designing scalable systems, working with APIs (REST, WebSockets, gRPC), state management, performance optimization, browser APIs, and security concepts, with bonus experience in Web3 technologies such as Solana, wallet integrations, or blockchain UX patterns. They should thrive in a high-ownership, fast-moving environment, enjoy shaping products end-to-end, mentoring others, and building polished, user-focused experiences.

💬 Potential Interview Questions

How would you architect a large-scale React/Next.js application for maintainability and performance?
I would organize the application by feature boundaries, create reusable component systems, separate business logic from UI, and optimize rendering and state updates for scalability.
What techniques do you use to optimize frontend performance in data-heavy applications?
I use code splitting, lazy loading, memoization, virtualization for large lists, efficient state management, and profiling tools to identify unnecessary renders or bottlenecks.
How do WebSockets differ from REST APIs, and when would you use each?
REST is request-response based and works well for standard CRUD operations, while WebSockets provide persistent real-time communication and are useful for live updates such as financial data or blockchain events.
What security concerns should be considered in frontend applications handling financial assets?
Important areas include protecting tokens and credentials, preventing XSS attacks, enforcing CSP rules, validating inputs, handling authentication securely, and following least-privilege principles.
How would you design a frontend application interacting with blockchain systems?
I would create clear abstractions around wallet connections, transaction handling, and blockchain state while ensuring the UI communicates transaction status and failures clearly.
What role do Web Workers play in modern web applications?
Web Workers allow computationally expensive tasks to run in background threads without blocking the main UI thread, improving responsiveness and user experience.
How do you approach state management in complex React applications?
I choose solutions based on application complexity. For shared global state I may use tools like Jōtai or similar libraries, while keeping local state close to components whenever possible.
How would you build and maintain a scalable design system?
I would define reusable components, document them with Storybook, establish design tokens, maintain consistency across teams, and balance flexibility with standardization.
What challenges are unique to frontend engineering in Web3 applications?
Challenges include wallet integration, transaction latency, blockchain state synchronization, security concerns, and making complex financial workflows understandable for users.
How do you maintain high code quality in a fast-moving engineering environment?
I rely on code reviews, testing, TypeScript, documentation, and clear engineering standards while maintaining a balance between development speed and long-term maintainability.
