While large financial firms comprise the backbone of the economy, their front and middle-office processes are still manual, spreadsheet-heavy, and fragmented.\nF2 is the leading vertical AI platform purpose-built for private markets and commercial banking. We transform dense, unstructured deal materials into auditable, decision-ready insights in minutes. This is not generic AI tooling. It is core infrastructure embedded directly into underwriting, credit, and portfolio workflows. We are the only fully vertical platform in this space with meaningful, proven revenue and real product-market fit.\nThe Role\nWe are seeking a hands-on Senior Software Engineer who loves building from 0→1 and shipping product that customers feel. You will actively write production code and deliver critical platform components from scratch, working closely with the team to power F2's AI-driven platform, helping private markets investors analyze deals with velocity and accuracy.\nWhat you'll do:\nBuild our product. Own and implement software features end-to-end across the stack that power our AI platform. In this role you are actively coding and delivering critical platform components from scratch, not just planning them.\n\nDeliver excellence and quality. Set and uphold coding standards, architectural patterns, and review processes; mentor engineers. Co-own a culture of practical, reliable, test-driven development that rapidly addresses real business needs.\n\nBuild for scale. Contribute to monitoring, scaling, and hardening the architecture of the platform and the systems behind it as enterprise demand grows.\n\nCross-functional collaboration. Partner closely with product, security, and go-to-market teams to translate our roadmap into features and deliverables that ship quickly and hold up in production.\n\nWhat you bring:\nFull-stack experience. 4+ years building production software across frontend and backend, with a track record of shipping features end-to-end.\n\nPassion for engineering and learning. You care about your craft and continuously push to get better.\n\nAI fluency. Comfort building with AI at the core - integrating LLMs, retrieval, or agents into real product experiences.\n\nModern web expertise. Strong grasp of modern web application development practices and patterns.\n\nBonus points. Familiarity with Python, FastAPI, TypeScript, Node.js, Supabase, and AWS is a plus.\n\nLocation: San Francisco\nEmployment Type: Full time\nLocation Type: Hybrid\nDepartment: Engineering, Product, Design (EPD)\nCompensation: $175K - $225K\nOffers Equity\nThe total rewards package at F2 includes base salary, equity (stock options), and benefits.","description_format":"text","description_chars":2805,"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","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Software & Embedded Finance","Financial AI"],"lifecycle":[{"event":"open","at":"2026-09-13T12:56:27Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":147500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":58,"band":"ok","label":"Likely open","p_open":1,"p_active":0.769,"p_room":0.75,"age_days":52,"expected_fill_days":55,"reasons":["conf:1","win:late"],"computed_at":"2026-11-02T06:13:15Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/f2-senior-software-engineer","json_url":"https://alion.io/job/f2-senior-software-engineer.json","meta":{"generated_at":"2026-11-02T21:18:22Z","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":29765,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":695973},"rest":"https://alion.io/mcp/rest/get_company?id=695973"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ff2-senior-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%2Ff2-senior-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%2Ff2-senior-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/f2-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ff2-senior-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":865358}},{"tool":"search_jobs","arguments":{"company":"f2.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":865358},"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.
