8+ years in testing distributed systems and analyzing inter-service API behavior.\n\n- Hands-on experience with request payload tampering, fuzzing, or adversarial API testing techniques.\n\n- Understanding of layered defense architectures, including the distinction between synchronous/inline validation and asynchronous/background verification processes.\n\n- Familiarity with testing data persistence and relational/hierarchical integrity in backend data stores.\n\n- Demonstrated discipline in test log archival, evidence capture, and structured documentation practices.\n\n- Solid understanding of backend/middleware architecture, failure modes, and system boundaries.\n\n- Familiarity with API testing tools and scripting for building custom fuzzing/tampering test cases.\n\n- Strong analytical and investigative skills for root-causing complex, systemic defects.\n\n- Experience executing controlled API replay or staging validation is strongly preferred.\n\n- Experience correlating API responses with observable application/account lifecycle states is preferred.\n\n- Experience supporting audit, compliance, or evidence-based reporting requirements is a plus.\nSkills\nAutomation Testing, Software Quality Assurance, API Testing, Distributed Systems, Testing, SDET, Software Testing Tools, System Testing","description_format":"text","description_chars":3501,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Biotechnology","Professional Services","Fraud Detection"],"lifecycle":[{"event":"open","at":"2026-10-05T12:29:30Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.9,"p_room":1,"age_days":4,"expected_fill_days":29,"reasons":["seen:4","velocity","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/welocalize-senior-software-test-engineer","json_url":"https://alion.io/job/welocalize-senior-software-test-engineer.json","meta":{"generated_at":"2026-10-10T19:11:24Z","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":"search","counted_by":"address","units_charged":0,"used_today":0,"day_limit":null,"remaining_today":null,"minute_limit":null,"resets_at":"2026-10-11T00:00:00Z"}},"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":1937083},"rest":"https://alion.io/mcp/rest/get_company?id=1937083"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwelocalize-senior-software-test-engineer"},{"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%2Fwelocalize-senior-software-test-engineer"},{"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%2Fwelocalize-senior-software-test-engineer"},{"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/welocalize-senior-software-test-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwelocalize-senior-software-test-engineer"}]}
