$170K - $220K USD
A rapidly scaling decentralised exchange processing $1.2B+ in average daily volume and $200B+ lifetime volume — one of the fastest growing DeFi platforms in the space. Built on a high-performance blockchain, the platform combines exchange, asset management, and borrow/lend into a single unified product. Backed by top-tier investors and moving fast.
You'll work directly with the founding team in a small, elite engineering org where you own what you ship end to end.
The Role
As a Principal SDET you'll sit at the intersection of development and quality — building the systems that keep the exchange bulletproof. This is a senior engineering role with real ownership over testing infrastructure, framework architecture, and quality strategy. You'll work directly with backend and frontend engineers to influence system design and drive a culture of quality across the entire platform.
What You'll Do
- Design, develop, and maintain scalable automated testing frameworks from scratch — API, UI, and integration
- Build tools to simulate high-concurrency trading environments and identify bottlenecks in the matching engine
- Validate smart contracts and cross-layer interactions across L1/L2
- Own CI/CD integration and drive a green-build culture
- Lead and mentor the existing test team
- Build internal tooling to assist engineers with debugging and local environment setup
What We're Looking For
- 5+ years in software engineering, SDET, or backend testing within Web3 or fintech
- Proven track record building and owning E2E automation frameworks from scratch in Python, Go, or TypeScript
- Deep understanding of distributed microservices architecture and QA methodologies
- Experience validating REST and WebSocket APIs under high-load conditions
- On-chain/off-chain integration testing experience — smart contracts, L1/L2 interactions
- Ability to script and verify complex financial scenarios — liquidations, cross-margin, funding rate calculations
- Strong documentation ownership
What's on Offer
- Top-tier compensation in the industry
- Unlimited PTO
- Comprehensive benefits package
- $3,000 tech budget for first-year setup
- No manager 1:1s, no unnecessary meetings
