Containerization for goods. SWIFT for money. Stripe for payments. Compliance is one of the last and largest - and the hardest, because trade rules aren't data to be looked up. They're a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.\nSphere built the system that solves it. Our AI (TRAM) ingests global trade law, interprets it, resolves conflicts across jurisdictions, and produces compliance determinations more reliable than human experts. We handle the entire lifecycle - calculation, registration, filing, remittance - at millisecond latency with zero downtime.\nBacked by a16z and YC. $21M Series A, 30%+ month-over-month growth, customers include ElevenLabs, Replit, Deel, Runway, and Lovable.\n\nSmall team, global surface area. Everyone owns a domain that would be a full team at a larger company. San Francisco, in office.\n\nThe problem keeps compounding. Expanding into input tax, withholding, e-invoicing, tariffs - each multiplies the complexity. Tens of millions of transactions today, billions ahead.\n\nTHE ROLE\nSphere is looking for senior full stack engineers who will own and build out new product lines (input tax, withholding tax, e-invoicing, tariffs) as well as mission critical parts of the Sphere platform (filing infrastructure, tax engine and AI / agentic related features).\nThese areas are key levers towards scaling Sphere and growing ARR, meaning that your work will have a direct impact on the growth of the business on a daily basis.\nWHAT YOU'LL DO\nWithin weeks:\nShip mission critical features that clients will use daily - e.g. filing infrastructure\n\nOwn and manage a feature and drive measurable outcomes\n\nWork directly with customers like Eleven Labs, Lovable and Deel to improve / optimize that key component of the platform (e.g. improve filing generation and submission speed [x]%)\n\nWithin months:\nOwn the end-to-end development of new products lines that will help build out our AI-native revenue-based compliance platform\n\nLead / mentor additional engineers in component areas that you have worked in\n\nREQUIREMENTS\nExperience in Python . Our core application backend and data pipeline services are built with Python and Django\n\nWhile frontend / React may not be your primary focus, you’re not afraid to dive in when needed\n\nVery strong attention to detail. When you work with numbers this is a non-negotiable - it’s not enough to be 99% right.\n\nNICE TO HAVES\nExperience working with large volumes of transaction data. You’ll be getting very familiar with it!\n\nExperience with Django or Python ORM\n\nWHO YOU ARE\nYou'll thrive here if:\nYou're a Dog. You've been underestimated, gone through struggle, and never stopped running. You have a chip on your shoulder and enormous drive. You look at Stripe, Deel, and Flexport all punting on compliance and think: good, that means the opportunity is ours. Hunger beats pedigree.\n\nEarly stage is in your bones. You've built things where there's no playbook and nobody handing you the answer. You define the problem instead of waiting for instructions.\n\nYou own it end to end. Give you a goal and you figure out your own path. Small team, global surface area - everyone owns a domain that would be a full team at a larger company. No one tells you how.\n\nYou believe speed and accuracy are both possible. We're building a complex product that requires robustness and 100% uptime, and we have to build at our customers' pace. Move fast. Don't break things. Both.\n\nBeing in the room is a feature, not a cost. Being in SF isn't a policy, it's how the work gets done. The speed and density of collaboration we need doesn't survive over video.\n\nThis won't be a fit if:\nYou need structure handed to you or ambiguity feels draining rather than motivating\n\nYou want to manage people more than own hard problems (we're a flat, experienced team - everyone builds)\n\nYou're used to \"good enough\" shipping (small errors have outsized impact here)","description_format":"text","description_chars":4117,"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":["RegTech, AML & Compliance","Accounting & Tax Software"],"lifecycle":[{"event":"open","at":"2025-09-16T00:01:56Z"},{"event":"open","at":"2026-09-25T17:02:12Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.133,"p_room":0.28,"age_days":396,"expected_fill_days":26,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":280000,"is_top_pay":true},"html_url":"https://alion.io/job/sphere-senior-full-stack-engineer-2","json_url":"https://alion.io/job/sphere-senior-full-stack-engineer-2.json","meta":{"generated_at":"2026-10-18T01:41:45Z","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":2812,"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":28817},"rest":"https://alion.io/mcp/rest/get_company?id=28817"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsphere-senior-full-stack-engineer-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%2Fsphere-senior-full-stack-engineer-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%2Fsphere-senior-full-stack-engineer-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/sphere-senior-full-stack-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsphere-senior-full-stack-engineer-2"}]}
