Principal SDET / QA Engineer | Remote

$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
