Summary: 

This is an opportunity for an experienced and talented Sr. QA Engineer/SDET to help build an innovative and market leading product at a fintech from an early stage.

The Senior QA Engineer / SDET will contribute to scaling our blockchain and AI testing practices focusing on blockchain validation, verification and testing processes using various non-UI and UI methods.  This role blends traditional automation engineering with protocol-level validation, observability-driven testing, and infrastructure-aware debugging. The individual will work in partnership with senior engineers as well as business to ensure quality delivery of solutions and implementations.

Our business operates in the growing sector of private markets and touches many of the fastest-evolving areas in the digital world today, such as blockchain and AI. As a result, we’re looking overall for engineers who are agile, can think on their feet and most importantly, are willing to contribute positively to the culture and community of an ambitious fintech organization.

Key Responsibilities: 

• Ability to break down solutions conceptually into testable components and develop plans for testing, verification and validation.  
• Identify solution risk areas and develop test harnesses that fit into the SDLC
• Utilize tools and test harnesses to accelerate current testing practices
• Work with Engineering team to evolve testing practices to improve coverage, ensure compliance and accelerate timelines
• Demonstrate test coverage with test solutions above
• Integrate test practices into CI/CD solutions that generate metrics and visibility 
• Perform functional, regression, integration, and performance testing using solutions above
• Collaborate with developers, product managers, and other stakeholders to understand requirements and ensure comprehensive test coverage. 
• Foster an open-minded approach with regards to test tools and approaches
• Identify, document, and track bugs using bug-tracking tools (e.g., JIRA).

• Continuously improve testing processes and strategies to enhance software quality. 
• Identify inconsistencies in requirements including key responsibilities, skills or qualifications
  
  

• Roughly 5+ years experience in software testing/sdet roles with an emphasis on various automated solutions where UI is not the main focus.  
• Experience with blockchain-based solutions in testing and validation
• Experience with Foundry/Hardhat in either testing and/or development capacity.  
• Experience with Smart Contract development (Solidity,Rust) challenges
• Strong problem-solving skills including someone who:
  • Investigates root causes, not symptoms
  • Uses multiple system surfaces to validate truth
  • Understands eventual consistency
  • Is a comfortable testing infrastructure without GUIs
  • Treats observability as a testing tool
  • Thrives in ambiguous, evolving environments
• Blockchain internal architecture familiarity (e.g. EVM vs IBC vs Consensus)
• API/RPC/gRPC Testing experience with industry tools and/or home grown.
• Database solutions such as MongoDB, PostGres or other NoSQL solution.
• Strong understanding of SDLC and STLC.
