Research Scientist - Audio Codec

Mirelo

Mirelo AI is building the next generation of creative tools by generating realistic sound, speech and music from video. We develop cutting-edge foundational generative AI models that "unmute" silent video content and create custom, hyper-realistic audio for gaming, video platforms, and creators. Our technology empowers global storytellers to transform their content. We 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. About the Role At Mirelo, you’ll work at the centre of how we build the next generation of multimodal video-to-audio models. This role is deeply hands-on and research-heavy: with a great H100/200-per-engineer ratio you explore and build new multimodal models and push the boundaries of what’s possible in music, sound, and speech generation. You’ll collaborate closely across research and engineering, run focused ablations, and translate experimental results into clear next steps for the team. From data curation to deployment, you’ll help shape the full lifecycle of the models that power our products and partnerships. KEY RESPONSIBILITIES * Design, implement and train large-scale multimodal generative models for audio generation (diffusion and/or autoregressive models). * Explore new modeling ideas for audio generation (music, sound, speech) while taking inspiration from the language and image domains. * Develop and experiment with post-training for new capabilities (fine-grained control, in/out-painting, editing, …) * Conduct rigorous ablation studies, get actionable insights and communicate results to the team to discuss new research directions. * Contribute hands-on to all stages of model development including data curation, experimentation, evaluation, and deployment. IDEAL CANDIDATE PROFILE * Hands-on experience in training large-scale generative models in a fast-paced research environment. * Deep understanding of cutting-edge methods and ML research in at least one of the domains: image, language, video or audio (specific audio experience not necessary, but nice to have). * Strong proficiency in PyTorch, transformer architectures, and the full ecosystem of modern deep learning. * Solid understanding of distributed training techniques—FSDP, low precision training, model parallelism * Strong track-record in working on generative models (publications in top-tier venues, open-source contributions or applied ML projects). NICE TO HAVE * Proficiency with profiling, debugging, and optimizing single and multi-GPU operations using tools like Nsight or stack trace viewers. * Strong software engineering skills/experience in collaborating on large codebases that go beyond PhD research code. * Experience with generative models for audio (sound, music or speech) and audio codec design. WHY JOIN? * Join 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. * True ownership from day one. You'll have genuine autonomy and responsibility. Your ideas and work will directly shape our product and company direction. * Competitive compensation and equity. We offer strong packages that ensure you share in the success you help create. * Build for the next generation of creators. Be part of the innovation that will transform how creators work and thrive. We welcome applications from all individuals, regardless of ethnic origin, gender, disability, religion or belief, age, or sexual orientation and identity.

MOIA

JOIN US AS A WORKING STUDENT COMPLIANCE ENGINEERING (ALL GENDERS) IN OUR CLOUD & PLATFORM ENGINEERING TEAM AND HELP SHAPE THE FUTURE OF AUTONOMOUS MOBILITY! Join us as a Working Student Compliance Engineering (all genders) in our Application Security team and help shape the future of autonomous mobility! Our Application Security Team is a group of cybersecurity experts providing shared security services for MOIA's autonomous driving operations. Sitting within the Cloud System Development Department, we safeguard the systems that power the next generation of urban mobility. We work at the exciting intersection of cutting-edge technology, regulatory compliance, and artificial intelligence — ensuring that as our autonomous vehicles move forward, they do so securely and in full compliance with evolving legal frameworks. This is a unique opportunity to pioneer the emerging field of Compliance / Legal Engineering — where law meets code. As autonomous driving technology accelerates, so does the complexity of the regulatory landscape surrounding it. We're looking for a curious, motivated working student who wants to build the bridge between legal compliance and technical automation. Whether you come from a legal background with a passion for technology, or a technical background with a fascination for law and standards, you'll find  meaningful work here that shapes how an entire industry approaches compliance. WHAT YOU WILL DO * Design and deploy agentic AI workflows to automate compliance processes for autonomous driving operations (e.g., via AWS Bedrock AgentCore). * Implement automation solutions that translate complex regulatory requirements (e.g., EU AI Act, NIS2, CRA, GDPR, etc.) into enforceable technical controls. * Work hands-on with compliance automation platforms (e.g., Vanta) and cloud security posture management tools (e.g., Wiz) to monitor and maintain our compliance posture. * Collaborate with cross-functional teams — including security engineers, data scientists, autonomous driving safety experts, legal counsel, risk management, and audit functions — to identify and address compliance gaps. * Research and map applicable legal frameworks and international standards (e.g., ISO 27001, ISO 21434, SOTIF, type-approval regulations, etc.) to our technical infrastructure. * Contribute to the development of internal tooling and CI/CD pipelines that embed compliance checks directly into software delivery processes (e.g., via MCP servers). * Support the creation of documentation, reports, and dashboards that communicate compliance status to both technical and non-technical stakeholders. * Explore emerging approaches to regulatory technology (RegTech) and propose innovative solutions to keep MOIA ahead of evolving requirements. WHAT WILL HELP YOU TO FULFILL YOUR ROLE  * You are currently enrolled in a full-time Bachelor's or Master's program. * To support your personal development and for you to take ownership of projects and processes, you should be enrolled for at least one year. * You communicate with clarity and confidence in English (C1 CEFR level) comfortable engaging with diverse stakeholders in a fast-paced environment (must have requirement) * You bring a genuine interdisciplinary mindset: if you're from a legal background, you have a strong hands-on interest in AI, coding, and technology implementation (actual code, not just theory or AI laws); if you're from a technical background, you have a real curiosity about law, regulation, and standards in autonomous driving * You are proficient in at least one programming or data manipulation language or have a demonstrated willingness and ability to learn quickly * You have foundational knowledge of — or eagerness to develop skills in — cloud computing (primarily AWS) and/or cybersecurity principles * You understand (or want to learn) CI/CD concepts and modern software development practices * You are self-driven, organized, and able to manage your time effectively in a remote-first setting Bonus points if you bring: * Experience (including internships or academic projects) in autonomous driving, automotive, software development, cloud computing, or compliance * Familiarity with regulations such as the EU AI Act, NIS2 Directive, Cyber Resilience Act (CRA), GDPR, or similar * Exposure to international standards like ISO 27001, ISO 9001, ISO 21434, frameworks from NIST and ENISA, or regulatory environments outside of Germany * Project management skills or experience coordinating work with multiple stakeholders We welcome applicants from diverse backgrounds — even if you don’t meet every requirement.
