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, we’re pushing the limits of what generative audio can do, and our ability to innovate depends heavily on the quality of our underlying audio representations. In this role, you’ll work at the core of our modeling stack - designing, training, and evaluating neural audio codecs that directly shape the performance of our next-generation music and sound models. You’ll collaborate closely with the model team, experiment with both continuous and discrete representations, and build the evaluation tools that help us understand what actually moves the needle. Your work will sit at the foundation of building the best-sounding generative models in the world.\nKey Responsibilities\nDevelop and implement new neural audio codecs for sound, music and speech that push the state-of-the art in sound quality and are optimized for the the use case of generative models.\n\nThink about the specific challenges that arise when the codec is primarily used as a latent representation in the context of generative audio models (in the end, the ultimate goal is to build the best audio generative models)\n\nExplore the trade-offs of continuous (as typically used for diffusion models) vs. discrete audio representations (as typically used for autoregressive models).\n\nDevelop benchmarking pipelines for codec evaluation\n\nConduct initial experiments with generative models to verify that a new candidate codec is actually useful for our downstream tasks.\n\nIdeal Candidate Profile\nStrong background in deep learning for audio: neural codecs, source separation, speech models, or generative audio systems\n\nSpecific hands-on experience in designing and training neural audio codecs\n\nSolid understanding of audio signal processing fundamentals\n\nStrong track record (research and/or open-source) in the field of audio ML\n\nNice to Have\nHands-on experience with generative audio models and good intuition of how the choice of the codec influences the training and performance of the generative model\n\nStrong publication record (e.g., NeurIPS, ICML, ICLR, Interspeech, ICASSP, WASPAA)\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":3372,"description_truncated":false,"requirements":{"experience_years_min":null,"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":"2026-08-30T01:12:07Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.137,"p_room":0.28,"age_days":317,"expected_fill_days":26,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/mirelo-ai-research-scientist-audio-codec","json_url":"https://alion.io/job/mirelo-ai-research-scientist-audio-codec.json","meta":{"generated_at":"2026-10-18T06:04:31Z","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":9076,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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-research-scientist-audio-codec"},{"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-research-scientist-audio-codec"},{"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-research-scientist-audio-codec"},{"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-research-scientist-audio-codec\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmirelo-ai-research-scientist-audio-codec"}]}
