You’ve ideally seen a startup grow\n* **Precision Mindset:** You understand that in fintech, a bug isn’t just a ticket; it’s a financial consequence. You care about decimal precision and idempotency.\n* **Pragmatic Architecture:** We don’t follow a named architecture style. We structure our code around business logic, clear entry points, explicit boundaries, and readability by anyone on the team. We care about code that makes sense, not code that follows a manifesto.\n* **Product-Minded Engineering:** You don’t just “write tickets.” You understand the business logic behind the code and take ownership of the features you build. You enjoy collaborating with product stakeholders to ensure the technical solution perfectly serves the user experience.\n* **Domain Curiosity:** A background in finance or fintech is a plus, but not a requirement. Private equity has its own logic and vocabulary; we’ll teach you the domain. What matters is that you’re genuinely curious about how it works.\n* * *\n### **What we offer**\n* **High-Growth Environment:** A front-row seat in a startup shaping the future of private equity. Ranked #14 in the Sifted 250, Europe’s fastest-growing startups by revenue. Today: €500M+ in assets under administration, 25,000+ investors, and 450+ investment clubs across 100+ nationalities.\n* **Tech Excellence:** A culture that values quality over quick fixes. We invest in a type-safe, well-structured codebase and modern developer experience, because good engineering compounds over time.\n* **AI-Augmented Engineering:** AI is embedded in how we work, from development workflows to product features. It makes us faster. But ownership stays human: every engineer understands, owns, and stands behind every line that goes to production. AI is a tool, not a crutch.\n### **Flexibility & Culture**\n* **Hybrid Work:** Beautiful offices in Paris or Toulouse. 2 to 3 days remote per week.\n* **Ambitious Peers:** Work with a high-caliber team driven by excellence and continuous learning.\n### **Benefits & Perks**\n* **Compensation:** Competitive salary (75-90K) + Employee Stock Options Plan.\n* **Health & Well-being:** Alan insurance (50% covered) and Swile restaurant card (€10/day).\n* **Time Off:** 25 days of holidays + RTT.\n* **Sustainable Commute:** €600/year “Forfait Mobilité Douce” for eco-friendly transportation.\n* **Gear:** High-end MacBook as your standard working tool.","description_format":"text","description_chars":3184,"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":["Apple Macbook","Continuous learning","Equity","Hybrid work","Stock options"],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:16:28Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.854,"p_room":0.9,"age_days":20,"expected_fill_days":36,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":101274,"is_top_pay":false},"html_url":"https://alion.io/job/roundtable-senior-backend-developer-mf","json_url":"https://alion.io/job/roundtable-senior-backend-developer-mf.json","meta":{"generated_at":"2026-10-14T01:46:05Z","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":2557,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":1876004},"rest":"https://alion.io/mcp/rest/get_company?id=1876004"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Froundtable-senior-backend-developer-mf"},{"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%2Froundtable-senior-backend-developer-mf"},{"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%2Froundtable-senior-backend-developer-mf"},{"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/roundtable-senior-backend-developer-mf\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Froundtable-senior-backend-developer-mf"}]}
