As a Senior Staff Software Engineer, you will drive cross-organizational technical impact, establish technical direction, spot systemic risks and opportunities, build patterns and frameworks, steward the health of multiple systems, and shape engineering culture. You should have 10+ years of software engineering experience, a deep mastery in one or more technical domains, and a proven track record of cross-org impact.\nMissions\nDrive cross-org technical impact by creating capabilities that don’t yet exist, measured by movement in company-level metrics and the durability of the systems you leave behind.\nEstablish technical direction that holds across org boundaries, through strategy docs, RFCs, and architecture reviews, reducing the need for repeated alignment and enabling teams to make good decisions independently.\nSpot systemic risks and opportunities others miss, positioning multiple orgs to respond before problems become crises, by staying close to the business and maintaining deep context across domains.","description_format":"text","description_chars":1099,"description_truncated":false,"requirements":{"experience_years_min":10,"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":["Commerce","Marketplaces","Social Commerce"],"lifecycle":[{"event":"open","at":"2026-10-09T04:17:57Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 48 · green card filings: 8","filings_12m":48,"filings_prev_12m":34,"green_card_filings_12m":8,"median_offered_wage_usd":208929,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":31}],"liveness":{"score":46,"band":"ok","label":"Likely open","p_open":1,"p_active":0.483,"p_room":0.945,"age_days":8,"expected_fill_days":16,"reasons":["conf:2","stale_co","velocity","win:mid"],"computed_at":"2026-10-10T05:45:15Z"},"pay":{"stated_usd_annual":330000,"is_top_pay":true},"html_url":"https://alion.io/job/whatnot-senior-staff-software-engineer","json_url":"https://alion.io/job/whatnot-senior-staff-software-engineer.json","meta":{"generated_at":"2026-10-11T21:32:20Z","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":10498,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"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":5086},"rest":"https://alion.io/mcp/rest/get_company?id=5086"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwhatnot-senior-staff-software-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%2Fwhatnot-senior-staff-software-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%2Fwhatnot-senior-staff-software-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/whatnot-senior-staff-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwhatnot-senior-staff-software-engineer"}]}
