Our platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility. Our platform doesn’t just assure system correctness and reliability, it exists because developers need something better. If you’ve ever experienced the pain of a production outage, had a bad week on-call, or had a release delayed by weeks because of one killer bug - you’ll understand exactly why we’re doing what we do. If you're passionate about developer-first products, system resilience, and correctness, we’d love to talk.\nAbout the Role\nWe’re hiring an Applied AI Software Engineer to build AI native products, integrations, API management, and more, that help our Finance and Accounting teams. Finance here spans FP&A, Accounting, Tax, Payroll, Reporting, SalesOps, Treasury, Equity Management, AP, AR, and Finance/Accounting Ops. The team is moving fast as the company scales, and there’s a big opportunity to automate the remaining manual work and free them up for higher value work.\nYou’ll work at the intersection of software engineering, applied AI, data, and Finance operations.\nWhat You’ll Do\nWork directly with Finance and Accounting to understand how they work, where they get stuck, and how they could do more with technology.\n\nDesign, build, and ship full stack products that use AI to help non technical teams get work done.\n\nBuild everything from lightweight agent workflows and automations to production applications for reporting, reconciliation, close support, and other Finance and Accounting problems.\n\nTake manual effort off the team and help shorten the close.\n\nMake pragmatic build versus buy decisions. The right solution might use an existing tool, a reusable agent skill, a custom integration, or a full application.\n\nSupport ERP implementation and management, along with other new software implementations and changes coming down the pipe.\n\nPartner with Finance, Accounting, and RevOps to integrate with the systems they use, like our ERP and Salesforce.\n\nBuild for the controls Finance needs: testing, monitoring, documentation, version control, audit trails, and access management.\n\nKeep AI work from being siloed. Today it lives with individuals on the team; help turn it into shared tools, reports, and a source of truth that can be maintained and audited as we grow.\n\nSupport globalization and the expansion of the Finance team.\n\nWhy Join Us?\nJoin a collaborative, kind team supporting a rapidly growing company.\n\nWork with the resources - tools, teammates, and world-class experts - to do portfolio worthy work.\n\nUse and explore AI in an environment that does not tolerate workslop.\n\nPreferred Qualifications\n4+ years of professional software engineering experience, including independently shipping and operating production systems.\n\nExperience shipping an LLM powered product, feature, or workflow for real users. You understand the difference between an impressive prototype and a system people can depend on.\n\nExperience working directly with non technical users to understand their workflows, test ideas, and improve products through feedback.\n\nExperience integrating with business systems such as ERP and accounting platforms, Salesforce, HubSpot, Slack, or data enrichment platforms.\n\nStrong product and engineering judgment. You can move quickly when the problem calls for an experiment and build for reliability, auditability, and access control when the solution becomes business critical.\n\nOur current stack for internal applications includes TypeScript, React, and AWS. Experience with these tools is helpful, but we care more about strong engineering fundamentals and the ability to learn.\nNice to Have\nCPA\n\nStart-up experience building from scratch","description_format":"text","description_chars":3838,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Software Testing & QA"],"lifecycle":[{"event":"open","at":"2026-11-11T18:46:21Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":72500,"route":null,"cap_exempt":false,"checked_at":"2026-11-11T07:38:50+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":77,"reasons":["conf:0","win:early"],"computed_at":"2026-11-11T19:44:43Z"},"pay":null,"html_url":"https://alion.io/job/antithesis-applied-ai-software-engineer","json_url":"https://alion.io/job/antithesis-applied-ai-software-engineer.json","meta":{"generated_at":"2026-11-11T19:44:43Z","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":38364,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"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":7620},"rest":"https://alion.io/mcp/rest/get_company?id=7620"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fantithesis-applied-ai-software-engineer"},{"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%2Fantithesis-applied-ai-software-engineer"},{"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%2Fantithesis-applied-ai-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/antithesis-applied-ai-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fantithesis-applied-ai-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4085504}},{"tool":"search_jobs","arguments":{"company":"antithesis.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4085504},"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.
