ABOUT US
We're the world's leading provider of secure financial messaging services, headquartered in Belgium. We are the way the world moves value - across borders, through cities and overseas. No other organisation can address the scale, precision, pace and trust that this demands, and we're proud to support the global economy.
We're unique too. We were established to find a better way for the global financial community to move value - a reliable, safe and secure approach that the community can trust, completely. We're always striving to be better and are constantly evolving in an ever-changing landscape, without undermining that trust. Five decades on, our vibrant community reflects the complexity and diversity of the financial ecosystem. We innovate diligently, test exhaustively, then implement fast. In a connected and exciting era, our mission has never been more relevant. Swift now has a presence in 200+ countries and legal territories to serve a community of more than 12,000 banks and financial institutions.
As a Blockchain Test Engineer at S.W.I.F.T, you will play a crucial role in ensuring the quality, reliability, and security of our blockchain-based solutions. You will be responsible for designing, developing, and executing comprehensive test strategies to validate the functionality, performance, and integrity of distributed ledger technologies integrated into our financial messaging infrastructure.
What to Expect:
In this role you will:
Design, develop, and implement robust test plans, test cases, and test scripts for blockchain applications, smart contracts and related distributed systems
Execute various types of testing, including functional, integration, performance, security, and regression testing, specifically tailored for blockchain environments
Test and integrate blockchain protocols and platforms, including Ethereum-compatible networks (e.g., Hyperledger Besu), Cosmos and Canton
Test smart contracts for correctness, security vulnerabilities, and edge cases
Collaborate closely with development teams and blockchain architects to understand technical specifications and ensure testability of features
Perform load, performance and stress testing to assess scalability and transaction throughput
Validate blockchain network behavior, including consensus mechanisms, node synchronization, and fault tolerance
Test integrations with wallets, APIs, backend services
Identify, document, and track software defects and work with development teams to ensure timely resolution
Develop and maintain automated test frameworks and tools to improve efficiency and coverage of blockchain testing
Contribute to the continuous improvement of testing processes, methodologies, and best practices within a blockchain context
Stay up-to-date with emerging blockchain technologies, testing tools, and industry trends
Participate in code reviews and provide constructive feedback to enhance code quality and testability
Ensure adherence to S.W.I.F.T.'s quality standards and regulatory compliance requirements in all testing activities
What will make you successful:
We are seeking professionals with:
Bachelor's Degree in Computer Science, Software Engineering, or a related field
Proven experience in software quality assurance or testing, with a significant focus on blockchain or distributed ledger technologies
Solid understanding of blockchain fundamentals, including consensus mechanisms (PoW, PoS, BFT), smart contracts, cryptography, and distributed system architectures
Proficiency in at least one programming language commonly used in blockchain development or testing (e.g., Python, JavaScript, Go, Java, Solidity)
Experience with test automation frameworks and tools (e.g., Selenium, Playwright, Jest, Truffle, Hardhat)
Familiarity with CI/CD pipelines and tools (e.g., Jenkins, GitLab CI)
Strong analytical and problem-solving skills, with meticulous attention to detail
Excellent communication and collaboration skills, with the ability to articulate technical concepts clearly to both technical and non-technical stakeholders
Preferred Qualifications:
Master's Degree in Computer Science, Software Engineering, or a related field
Experience with performance testing and security testing methodologies for distributed systems
Knowledge of financial services industry standards and regulatory frameworks
Swift is unable to sponsor an employment authorization for this position now or in the future.
The estimated salary range for a new hire in this position in Virginia is $66,960.00 Annual MINIMUM to $124,354.00 USD Annual MAXIMUM. Salary may vary depending on job-related factors which may include knowledge, skills, experience, and location.
