Job description

Octagon Talent Solutions is a full-service technology recruitment and staffing company based in South Florida. We humanize technical recruitment by identifying candidates' long-term career goals and assessing cultural fit when presenting opportunities. Our focus on long-term relationships helps ensure placements that last.


JOB OVERVIEW:


We are looking for a Lead Quality Assurance Engineer for an exciting remote opportunity based in Miami. Our client is a leader in Web3 innovation, developing cutting-edge applications in cryptocurrency trading and blockchain infrastructure. This role provides a unique opportunity to influence the quality standards of next-generation financial technology products while collaborating with a highly skilled engineering team. In this critical position, you will work directly with the CTO and cross-functional teams to ensure the delivery of robust, secure, and high-performance crypto trading solutions.


RESPONSIBILITIES:

  • Lead the development and execution of comprehensive test strategies for cutting-edge crypto and Web3 applications, ensuring product excellence
  • Drive quality assurance through a mix of manual and automated testing approaches, covering integration, regression, load, and security testing scenarios
  • Establish robust defect management processes, including thorough documentation and tracking systems
  • Take ownership of issue resolution by working directly with engineering teams to investigate, reproduce, and resolve complex technical challenges
  • Implement proactive performance monitoring and reliability analysis to maintain system excellence
  • Spearhead continuous improvement initiatives for QA processes and automation frameworks
  • Champion quality standards through comprehensive testing protocols and detailed documentation to ensure successful releases


CORE REQUIREMENTS:

  • Strong knowledge of QA methodologies, tools, and processes
  • Proven ability to test large-scale, high-availability production systems
  • Experience with automated testing frameworks (Selenium, Cypress, Jest, Postman)
  • Excellent problem-solving, analytical skills, and attention to detail
  • Familiarity with blockchain technology (EVM, smart contracts, Web3)
  • Extensive QA experience in crypto/blockchain or fintech applications
  • Fluent English communication skills


TECHNICAL SKILLS (PREFERRED):

  • Performance testing expertise with JMeter, k6, or LoadRunner
  • Experience with CI/CD pipelines, containerization (Docker, Kubernetes)
  • Security testing and vulnerability assessment capabilities
  • ISTQB certification or equivalent
  • Open-source contributions to QA/testing projects


ADDITIONAL TECHNICAL REQUIREMENTS:

  • Experience with distributed systems testing and microservices architecture
  • Knowledge of API testing and WebSocket protocols
  • Familiarity with data consistency testing in distributed ledger systems
  • Experience with test environments in cloud platforms (AWS/GCP/Azure)


Our client's team works in a fast-paced, dynamic environment. This role is not your typical 9-to-5; we are seeking a meticulous QA professional who excels in delivering world-class quality for crypto products while collaborating with a small, senior team.

Please submit your resume, portfolio, GitHub profile, or examples of previous QA projects, especially those involving cryptocurrency, trading, or large-scale production applications.
