Paradex isn’t just another decentralized exchange; it’s the Everything Store for Finance. We’ve combined three powerful financial primitives -Exchange, Asset Management, and Borrow/Lend- all seamlessly composable and accessible through one unified account that uses your entire portfolio as collateral, including spot and derivative assets. Trade 250+ markets on a super exchange with zero fees, better-than-CEX liquidity, and institutional-grade privacy, all built on a blazingly fast blockchain.
Backed by top-tier investors and incubated by Paradigm, we’re scaling fast and building a team of mission-driven engineers to redefine what’s possible in decentralized finance. We have no product managers, no managers, no 1:1s at Paradex. No bullshit. Just code. You’ll work directly with our CEO and a small, elite team of builders in the trenches every day, pushing the limits of performance and UX.
Fair warning: this is not an easy place to work. We will push you hard. But you’ll grow faster than you thought possible, and you’ll do some of the most meaningful, high-impact work of your life. You’ll own what you ship end to end, tackle real technical challenges (not just UX tweaks), and help shape the future of decentralized finance. Join us on the frontline ⚔️

As an SDET at Paradex, you are a developer focused on building the systems that ensure our exchange remains bulletproof. You will sit at the intersection of development and quality, designing sophisticated automation frameworks to validate high-frequency trading engines, smart contracts, and complex financial logic.
What you’ll do
Framework Architecture: Design, develop, and maintain scalable automated testing frameworks from scratch (API, UI, and Integration). Deep Integration: Work alongside Backend and Frontend engineers to influence system design for better testability. Performance & Load: Develop tools to simulate high-concurrency trading environments and identify bottlenecks in our matching engine. CI/CD Ownership: Integrate automated suites into our deployment pipelines to ensure a "green-build" culture. Smart Contract Validation: Participate in the testing of on-chain logic and cross-layer interactions (L1/L2). Tooling: Build internal tools to assist developers in debugging and local environment setup.
What you bring
Experience: 5+ years in Software Engineering, SDET or Backend Testing within Web3 or Fintech. Framework Mastery: Proven track record of architecting and maintaining scalable E2E automation frameworks from the ground up (using Python, Go, or TypeScript). Distributed Systems: Deep understanding of QA methodologies and system dependencies within a distributed microservices architecture. Protocol Testing: Expertise in validating REST and Websocket APIs under high-load conditions, with a focus on low-latency data integrity. Consistency & State: Deep understanding of asynchronous systems, ensuring state consistency across the frontend, off-chain order book and the database. On-Chain/Off-Chain Integration: Experience validating the bridge between off-chain matching engines and on-chain settlement (L1/L2 smart contracts). Financial Logic: Ability to script and verify complex financial scenarios, including multi-asset cross-margin, liquidation cascades, and funding ratecalculations.
Competitive Pay: Top-tier compensation in the industry. Generous PTO: Unlimited vacation. Full Benefits: Comprehensive packages tailored by country. Tech' budget: 3,000 USD for your first-year setup. No manager 1:1s and no bullshit meetings.
