Enterprises like Verkada, Glossier, Yamaha, and Kodak run their trade compliance on us: the intelligence layer that queries fragmented data, audits continuously in the background, drafts and files intelligently, and surfaces the money that's been quietly slipping away for years. We started with duty drawback, a $10B/year opportunity hiding in plain sight, and we're now building the entire operating system for how enterprises stay compliant and claw back every dollar they're owed.\nHere's the platform we're building, product by product:\nDuty drawback: recover tariffs paid on goods later exported, returned, or destroyed. (Live.)\n\nIEEPA / reciprocal tariff recovery: claw back refunds on the new wave of reciprocal tariffs. (Live.)\n\nEntry & export audits: an AI audit agent that reviews every entry line by line and catches errors before they ever reach CBP. (Shipping now, and you could own pieces of it.)\n\n...with more on the roadmap as we build out the full control tower.\nTariffs have been top of mind for everyone. Companies have gone from paying 25% to 145% tariffs. There's never been a better time to make a real world impact on real businesses.\nWho's building this\nPax was started by people who lived this problem. Penny Chen (CEO) holds a PhD from MIT and built optimization algorithms at Flexport and on Amazon's supply chain last-mile team. Chris Le is a repeat founder, previously at Brex, TikTok, and Amazon, where he worked on supply chain optimization for last-mile delivery. We started Pax because we saw billions in refunds sitting unclaimed while working alongside the importers who were owed them.\nWe're well-capitalized, we already have real enterprise customers, and we're looking for an early-career software engineer to take real ownership of the products above, early enough that your work shapes the company and the $10B+ industry we're transforming.\nWhat you'll do\nOwn real features end-to-end: API design, backend logic, frontend UI, and everything in between\nBuild tools that make complex regulations feel like magic\nWork directly with customers to understand what matters, then ship fast\nBuild with LLMs to solve real problems for real businesses, not imaginary ones\nWhat your first 90 days look like:\nWeek 1: Ship a real feature to production.\n\nFirst 30 days: Deliver an end-to-end project alongside a founder, something agentic, powered by LLMs.\n\n60 days: Independently own a vertical end-to-end, from spec to ship.\n\n90 days: Work directly with our enterprise clients, forward-deploying, incorporating their feedback, and building product in front of them.\n\nYou'll write systems that reconcile tens of millions of dollars in annual trade volume against thousands of pages of complex federal regulations, and turn PDFs of customs entries into structured, refundable data.\nThe ideal candidate\nHas built and shipped something they're proud of. Show us the GitHub, the side project, the thing you couldn't stop working on. We care more about what you've built than where you've worked.\nCan go deep on backend architecture and also cares that the UI feels crisp\nIs genuinely curious about building with LLMs, whether or not you've shipped with them before, and eager to learn fast\nUnderstands tradeoffs, knows when to move fast, and when to polish\nIs comfortable with ambiguity and thrives in early-stage environments\nDoesn't need permission to start something, but knows when to ask for input\nWants to own real outcomes, not just code\nHas hands-on experience (projects, internships, or work) with frameworks like React, Next.js, FastAPI, SQLModel, Postgres, etc.\nWe're a small team by design. This is early enough that your work will shape the future of the company, and the $10B+ industry we're transforming. This will be the most fulfilling work of your career.\nWe work from San Francisco, in-person. Our office is focused, fast, and full of energy. This is a hard requirement, no remote.\nIf you've built something you're proud of, we want to see it.\nRegarding Visa’s: we will only support TN visas or transfers. Due to time, we will not sponsor new H1-Bs.\nImportant: [redacted]","description_format":"text","description_chars":4305,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Freight Forwarding","Supply Chain & Logistics Software"],"lifecycle":[{"event":"open","at":"2026-08-28T03:31:05Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.347,"p_room":0.28,"age_days":50,"expected_fill_days":23,"reasons":["conf:0","win:tail","crowd:junior"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":150000,"is_top_pay":true},"html_url":"https://alion.io/job/pax-software-engineer-early-career-2","json_url":"https://alion.io/job/pax-software-engineer-early-career-2.json","meta":{"generated_at":"2026-10-18T04:40:07Z","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":6966,"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":47250},"rest":"https://alion.io/mcp/rest/get_company?id=47250"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpax-software-engineer-early-career-2"},{"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%2Fpax-software-engineer-early-career-2"},{"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%2Fpax-software-engineer-early-career-2"},{"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/pax-software-engineer-early-career-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpax-software-engineer-early-career-2"}]}
