Our technology empowers global storytellers to transform their content.\nWe recently closed a $41 million Seed round co-led by Andreessen Horowitz and Index Ventures with participation from Atlantic, and are rapidly expanding across Product, Engineering, Go-to-Market, and Growth.\nAbout the Role\nAt Mirelo, you’ll join a small, fast-moving team building real products on top of our generative audio models. This role is hands-on and high-ownership: you’ll ship end-to-end features across our stack, work directly with research and product, and help shape how our technology becomes something creators and partners actually use. As we scale our go-to-market efforts, the engineering work you do will sit at the heart of both user-facing products and deeper integrations with platforms, tools, and enterprise partners.\nKey Responsibilities\nBuilding and maintaining our products on top of our cutting-edge generative AI models for music and sound.\n\nHigh degrees of ownership: you will be responsible for shipping end-to-end features across the front and back ends of our stack, as well as helping set the direction of the features and products you're working on.\n\nCollaborate closely with our research teams and growth/sales teams and stay close to our users: spot practical opportunities, identify pain points, and turn them into actionable engineering tasks.\n\nWork comfortably with our current tech stack: TypeScript, React, Tailwind, shadcn, and Convex as the backend.\n\nWork with essential cloud services-primarily AWS Lambda and S3-for integrations, automation, and deployment workflows\n\nUse modern AI-assisted development tools (Cursor, Claude Code, etc.) to move fast while keeping craftsmanship high.\n\nCommunicate clearly with teammates, jump into discussions, and help drive the technical direction together.\n\nIdeal Candidate Profile\n5+ years of professional web development experience, preferably in fast-moving product or startup environments.\n\nStrong expertise in TypeScript (both frontend and backend), React, Tailwind, component libraries.\n\nSolid understanding of backend fundamentals: data modeling, migrations, performance, API design, security and data workflow.\n\nSelf-directed in a healthy way: you take ownership, move forward proactively, and keep the team in the loop.\n\nNice to Have\nBasic understanding of machine learning and experience using ML/LLM tooling in products.\n\nHands-on experience with Convex, or similar serverless backend platforms, and the ability to quickly become productive with it. Proficiency in Python.\n\nExposure to AWS beyond Lambda/S3 (CloudFront, IAM basics, monitoring).\n\nExperience contributing to or maintaining larger production codebases.\n\nWhy Join?\nJoin at a pivotal moment. We've secured fresh funding and are gaining traction - now is when your contributions can make a real difference to our success.\n\nTrue ownership from day one. You'll have genuine autonomy and responsibility. Your ideas and work will directly shape our product and company direction.\n\nCompetitive compensation and equity. We offer strong packages that ensure you share in the success you help create.\n\nBuild for the next generation of creators. Be part of the innovation that will transform how creators work and thrive.\n\nWe welcome applications from all individuals, regardless of ethnic origin, gender, disability, religion or belief, age, or sexual orientation and identity.","description_format":"text","description_chars":3694,"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":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Generative Audio & Music"],"lifecycle":[{"event":"open","at":"2025-12-03T19:55:01Z"},{"event":"open","at":"2026-09-25T15:13:45Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.19,"p_room":0.28,"age_days":319,"expected_fill_days":24,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/mirelo-ai-full-stack-software-engineer","json_url":"https://alion.io/job/mirelo-ai-full-stack-software-engineer.json","meta":{"generated_at":"2026-10-20T02:31:49Z","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":2811,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":40131},"rest":"https://alion.io/mcp/rest/get_company?id=40131"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmirelo-ai-full-stack-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%2Fmirelo-ai-full-stack-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%2Fmirelo-ai-full-stack-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/mirelo-ai-full-stack-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmirelo-ai-full-stack-software-engineer"}]}
