This role is responsible for ensuring the quality, reliability, and performance of our applications through a combination of manual and automated testing across front-end and back-end systems.The ideal candidate is passionate about software quality, enjoys working in a collaborative environment, and is motivated to improve testing processes, tools, and automation coverage.\nAbout Nucleus Security\nNucleus Security is transforming how security and development teams manage vulnerabilities at a scale. Our platform unifies vulnerability data across scanners and environments, enabling organizations to prioritize and remediate vulnerabilities efficiently. Through our integrations, we empower customers to ingest data from their existing tools with minimal setup and maximum reliability.Core Responsibilities\nWhat You Will Do\nEnsure the quality and reliability of assigned products across the full stack - UI, APIs, and data - defining test approach and risk coverage with the QA Manager, and leveraging AI tools to improve coverage and efficiency\nBuild, extend, and improve scalable automation frameworks in Selenium and Playwright that the team relies on, reducing manual testing effort and increasing confidence in every release\nAct as a quality advocate within the team - reviewing test code, sharing testing practices with peers, and raising design concerns early enough to prevent defects rather than catch them\nTesting & Quality Assurance\nPlan and execute test coverage for complex, cross-system features, including functional, regression, smoke, integration, and end-to-end testing\nDesign and execute manual and automated test cases covering functionality, performance, and reliability, including positive, negative, and edge cases\nAssess risk and prioritize testing effort, making clear recommendations on depth of coverage versus delivery timelines\nMap test cases to business requirements and functional designs, ensuring traceability and identifying gaps before development begins\nInvestigate complex or intermittent failures to root cause, distinguishing product defects from test instability and environment issues\nDocument and report defects, verify fixes, and ensure timely resolution in collaboration with development teams\nDatabase & Data Validation\nWrite and execute complex SQL queries to validate data integrity, transformations, and business logic across the application stack\nVerify data accuracy through ingestion, normalization, and processing workflows - record counts, deduplication, field-level mapping, and malformed or partial data\nValidate database interactions triggered by UI and API operations, and test data migrations, schema changes, and backfills for correctness and backward compatibility\nBuild and maintain reusable test data sets and database setup and teardown routines for reliable, repeatable automated runs\nAutomation & Frameworks\nImplement and review automated test scripts using Java with Selenium WebDriver and Playwright, following best practices such as the Page Object Model\nContribute to the architecture and long-term health of automation frameworks - structure, reusable components, reporting, and test data management\nIncorporate database validation into automated suites through query-based assertions and programmatic test data setup\nImprove automation reliability by reducing flakiness, execution time, and maintenance cost as suites grow\nIntegrate automated tests into CI/CD pipelines and support optimization within DevOps workflows, including parallel execution\nSupport performance and scale testing, and recommend tools and processes that measurably improve QA effectiveness\nAI-Assisted Testing\nHands-on experience using AI tools for test case generation, test data creation, and defect analysis\nFamiliarity with Model Context Protocol (MCP) tooling, such as Playwright MCP, for AI-driven browser interaction, exploratory testing, and test script generation\nExperience with AI-assisted coding tools for building and maintaining automation scripts, with sound judgment about where AI output needs human validation\nAbility to apply AI thoughtfully within QA workflows and share what works with the rest of the team\nCollaboration & QA Practices\nPartner with the QA Manager, developers, and product managers to clarify requirements and acceptance criteria\nSupport and mentor less experienced QA engineers through technical guidance, code review feedback, and knowledge sharing\nParticipate in design reviews and technical discussions, surfacing testability and reliability concerns early\nContribute to continuous improvement of QA processes, tools, and standards across the team\nWhat we’re looking for:\nRequired\n8+ years in software quality assurance, with at least 5 years in test automation\nStrong programming skills in Java, with demonstrated ability to write clean, maintainable, reviewable test code\nHands-on experience with Selenium WebDriver and Playwright, and with design patterns such as the Page Object Model\nExperience contributing to the design or significant refactoring of an automation framework, not just writing tests within one\nSolid API testing experience and strong SQL skills, with hands-on experience validating application behavior directly against relational databases\nWorking knowledge of CI/CD tooling and version control, with experience running automation reliably within pipelines\nStrong analytical and debugging skills, with a track record of driving complex issues to root cause\nPreferred (Nice to Have)\nExperience working in cybersecurity, vulnerability management, or security-focused products and environments\nFamiliarity with security concepts such as vulnerabilities, risk scoring, APIs, and data protection practices\nExperience with MCP servers or agent-based testing workflows beyond basic tool usage\nExperience testing ETL or data pipelines, or working with large-scale or NoSQL data stores\nExperience with performance or load testing, cloud environments, or containerized test infrastructure\nCommon Skills & Traits\nSelf-starter with a strong ownership mindset and the ability to wear multiple hats in a fast-paced environment\nStrong problem-solving and collaboration skills, with the maturity to disagree constructively\nAbility to quickly learn new tools, technologies, and frameworks - and to teach them to others\nWillingness to fail fast, iterate, and improve\nWhy Nucleus?\nNucleus is a truly unique solution that’s defining a market AND making an actual impact.\nWe’re biased, but you will get to work with one of the best teams in security. We have a lot to get done and we work extremely hard, but we have fun in the process.\nWork with a high-performing team that values creativity, autonomy, and innovation. \nCollaborate on meaningful products that improve the security posture of major organizations. \nEnjoy flexible remote work arrangements and a strong emphasis on work-life balance.","description_format":"text","description_chars":6984,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Cybersecurity","Information Technology"],"lifecycle":[{"event":"open","at":"2026-09-25T19:25:31Z"}],"visa":[],"liveness":{"score":81,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":0.9,"age_days":21,"expected_fill_days":35,"reasons":["conf:3","velocity","win:mid"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/nucleussec-senior-qa-automation-engineer-nucleus-security","json_url":"https://alion.io/job/nucleussec-senior-qa-automation-engineer-nucleus-security.json","meta":{"generated_at":"2026-10-18T04:15:42Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6424,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1760375},"rest":"https://alion.io/mcp/rest/get_company?id=1760375"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnucleussec-senior-qa-automation-engineer-nucleus-security"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fnucleussec-senior-qa-automation-engineer-nucleus-security"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fnucleussec-senior-qa-automation-engineer-nucleus-security"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/nucleussec-senior-qa-automation-engineer-nucleus-security\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnucleussec-senior-qa-automation-engineer-nucleus-security"}]}
