Be the go-to person for framework design, good standards testing practices.\nHelp shape the test strategy across products and services, making clear, practical decisions about coverage, risk and release readiness.\nWrite reliable, maintainable integration and end-to-end tests to the same engineering standards as production code. Build reusable utilities, mocks and simulators that make testing easier for the wider team.\nEmbed automated testing into CI/CD pipelines, giving engineers fast, meaningful feedback and confidence in their changes.\nKeep test suites and regression packs healthy by tackling flaky tests, removing duplication and ensuring coverage stays relevant as products evolve.\nTest across front-end applications, back-end services, APIs and distributed microservices, using tools such as Playwright, Cypress, REST Assured and Postman where appropriate.\nPlan and carry out performance and load testing using tools such as k6, Grafana k6 Cloud or JMeter, working with engineers to investigate bottlenecks and validate improvements.\nUse AI tools such as Claude, GitHub Copilot or similar to support test design, scaffold and maintain frameworks, generate test cases and investigate failures. Apply engineering judgement to review and validate AI-generated code and test results.\nExplore practical uses of AI agents for exploratory testing, fuzz testing and anomaly detection, alongside hands-on investigation and risk-based testing.\nWhere products include AI-powered features, develop evaluation approaches covering prompt regression, output quality and safety, and variability in model responses.\nWork closely with engineers, product managers and delivery leads to build quality into requirements and design decisions from the outset. Coordinate across squads to test shared journeys, service contracts and integrations.\nStay hands-on throughout delivery: investigate defects and production issues, carry out targeted manual testing, validate fixes and add automated coverage to prevent repeat failures.\nBring an independent quality perspective to architecture and release decisions. Ask difficult questions, challenge assumptions and raise concerns when the evidence does not support a release.\nMentor engineers and other testers, share knowledge and help create an environment where people can question decisions, surface risks and learn from failures without blame.\n\"Desirable Experience”\nEvidence of testing craft through frameworks you have built, improvements you have delivered, open-source contributions or examples you can discuss.\nPractical experience using AI coding assistants or agents, including writing effective prompts and critically evaluating their output.\nExperience with cloud-native testing, AWS environments, infrastructure as code such as AWS CDK, and consumer-driven contract testing with Pact.\nExperience evaluating AI-powered features and building repeatable checks for model behaviour.","description_format":"text","description_chars":3098,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Loyalty Programs","Property & Casualty Insurance","Business Travel"],"lifecycle":[{"event":"open","at":"2026-11-12T15:03:22Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:1","win:early"],"computed_at":"2026-11-12T16:19:06Z"},"pay":null,"html_url":"https://alion.io/job/collinson-sr-software-development-engineer-in-test-snr-sdet","json_url":"https://alion.io/job/collinson-sr-software-development-engineer-in-test-snr-sdet.json","meta":{"generated_at":"2026-11-12T16:19:06Z","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":34145,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1593},"rest":"https://alion.io/mcp/rest/get_company?id=1593"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcollinson-sr-software-development-engineer-in-test-snr-sdet"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fcollinson-sr-software-development-engineer-in-test-snr-sdet"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fcollinson-sr-software-development-engineer-in-test-snr-sdet"},{"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/collinson-sr-software-development-engineer-in-test-snr-sdet\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcollinson-sr-software-development-engineer-in-test-snr-sdet"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4172189}},{"tool":"search_jobs","arguments":{"company":"collinsongroup.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4172189},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
