Our Audit-Ready AI Agents connect to a company's existing finance stack-ERPs, banks, billing, payroll, CRM, contracts, spreadsheets, email, and Slack-and automate the work behind behind the entire order to cash process, record to report process, treasury management, financial reporting and and audit readiness.\nThe goal isn't to help the finance team write better prompts.\nThe goal is for finance teams to review exceptions while AI does the rest.\nWhat makes Hyphenate different is our Unified Finance Context -a financial understanding layer that captures transactions, policies, contracts, historical decisions, and accounting judgment. On top of it sit Audit-Ready AI Agents that can reason, explain their decisions, escalate uncertainty, and continuously improve.\nWe've raised $9M led by Foundation Capital, alongside BoldCap, Gaia Ventures, Aravind Srinivas (CEO of Perplexity), and finance leaders from Zuora, Ramp, Gusto, MongoDB, Zoom, and the Big Four.\nWhat You'll Own\nYou won't own tickets-you'll own a piece of the future accounting stack.\nEvery senior engineer owns a finance domain (revenue, cash, close, reporting, payroll, fixed assets, tax, or controls) and ships it end-to-end with a pod of 2-3 engineers.\nNo PM writes your specs. No architecture committee approves your ideas. You work directly with controllers, accountants, and CFOs to understand the problem, then build the system that replaces the manual process.\nProblems Worth Your Brain\nHow do you build AI agents that finance teams and auditors can trust? Verification, guardrails, observability, and evaluation systems for non-deterministic AI.\n\nHow do you give an agent the right financial context? Context engineering over transactions, ledgers, contracts, policies, and historical decisions-without bloat, drift, or data leakage.\n\nHow do you turn messy enterprise systems into a unified source of truth? Ingest, normalize, and reconcile data from ERPs, banks, payroll, billing platforms, CRMs, and email.\n\nHow do you orchestrate durable AI workflows in the real world? Long-running, replay-safe workflows across flaky, stateful enterprise systems.\n\nHow do you safely write back to systems of record? Idempotent, audit-ready updates to ERPs and financial systems with full traceability.\n\nA Few Strong Opinions\nThe engineer who can’t operate AI agents fluently is becoming obsolete, fast. Fluency with Claude, Cursor, and internal agent tooling is a second cortex.\n\n“Backend vs. frontend” is dissolving. The agents do the typing. The constraint is product judgment, system design, and the ability to close the loop from problem to shipped feature. Our engineers ship full-stack when the work calls for it.\n\nThe pod is the unit of leverage. Two engineers who can hold an entire module in their heads ship more than ten engineers who each own a slice. Specialization across pods, generalist within them. Our engineers raise the ceiling for every pod.\n\nThe accountant + engineer loop is the moat. Engineers who sit with controllers and build from what they see compound faster than the ones who don’t.\n\nWhat Great Looks Like Here\nYou can learn a finance workflow in the morning and ship it by the end of the day. The ability to quickly understand a domain and translate it into software is the single most important skill on the team.\n\nYou think like an owner. You're a current or future founder who scopes your own work, thinks from the customer's perspective, owns decisions, and drives outcomes without waiting for direction.\n\nYou solve problems end to end. The team is split vertically, so every engineer owns a part of the product and makes decisions across the LLM pipeline, infrastructure, backend, and UX.\n\nYou care about getting it right. A 100% solution beats an 80% one. When something breaks, you go to root cause.\n\nYou operate AI coding agents at a high level. You have opinions about which agent to use for which task. You’ve shipped real production code through them.\n\nWhat You Should Have Done Before\n5+ years of software engineering, mostly backend or infrastructure.\n\nStrong backend chops in a modern language - Python, Go, Java, Rust, or similar. Our stack is Python; if your deep experience is elsewhere, ramp fast.\n\nBuilt hard backend systems - distributed pipelines, transactional or ledger systems, integration platforms, or workflow engines.\n\nWorked at an early-stage startup (pre-seed through Series B).\n\nYou’ll Stand Out if\nYou've worked in fintech, ERP, accounting, payments, banking, treasury, audit, or compliance software.\n\nYou've built production AI agents, not just demos.\n\nYou've built evaluation frameworks, verification systems, or observability platforms for AI.\n\nYou've worked with data warehouses, financial systems, or enterprise integrations.\n\nYou've been the engineer customers asked for by name.\n\nThe Upside\nExceptional teammates with high ownership and direct access to customers, CFOs, controllers, and founders.\n\nTop-of-market compensation and meaningful early-stage equity.\n\nFull medical, dental, and vision coverage for employees and dependents, plus 401(k) match.\n\nMeals, a stocked NYC office, and the chance to help define an entirely new category: Audit-Ready AI for Finance.","description_format":"text","description_chars":5324,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-01T07:35:53Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.313,"p_room":0.28,"age_days":156,"expected_fill_days":29,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/hyphenate-software-engineer-senior","json_url":"https://alion.io/job/hyphenate-software-engineer-senior.json","meta":{"generated_at":"2026-11-07T07:03:59Z","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":1688,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":4492049},"rest":"https://alion.io/mcp/rest/get_company?id=4492049"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhyphenate-software-engineer-senior"},{"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%2Fhyphenate-software-engineer-senior"},{"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%2Fhyphenate-software-engineer-senior"},{"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/hyphenate-software-engineer-senior\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhyphenate-software-engineer-senior"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3584065}},{"tool":"search_jobs","arguments":{"company":"hyphenate.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3584065},"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.
