Job Title

Job DescriptionAbout Apna:Apna is India’s largest jobs and professional networking platform and one of India’s fastest unicorns. As we expand Bluemachines AI, our AI-first platform across voice, text, and multimodal workflows — we’re looking for a bold and curious Applied ML Scientist who wants to shape the future of applied Gen AI.Location: Bengaluru (Work from Office - Domlur)Team: AI & Machine LearningExperience: 2–7 yearsRequirementsWhat You'll do:Fine-tune and deploy LLMs, TTS, STT, and voice models for use in real-time conversations with millions of users.Convert unstructured, messy real-world audio/text data into clean, high-quality datasets for training and evaluation.Build inference pipelines optimized for low-latency, high-accuracy voice agents and multimodal interfaces.Work closely with infra and product teams to ship production-grade GenAI models with observability, fallback, and monitoring.Experiment with GANs, diffusion models, audio generation, and multimodal fusion to power next-gen AI agents.Own the full model lifecycle — from research and training to deployment, testing, and iteration.What we're Looking for:2-7 years of hands-on experience in AI / ML roles, ideally in startups or product-driven teams.Strong grasp of LLM fine-tuning, instruction tuning, or pretraining techniques.Familiarity with TTS/STT systems, Whisper, Tacotron, VITS, or other open source models .Experience with multimodal architectures, generative audio, GANs, or diffusion-based models.Ability to work with real-world messy data, design training pipelines, and debug model failure modes.Fluency in frameworks like PyTorch, HuggingFace, TensorFlow, and ecosystem tools (ONNX, Triton, LangChain, etc.).Passion for building high-impact AI features that ship to real customers.Why Join Us:Work at the cutting edge of LLMs, voice AI, and generative models — and ship real products, not just prototypes.Directly impact millions of users by powering AI agents that help with hiring, learning, and career growth.Collaborate with a world-class team of AI engineers, researchers, and product minds who move fast and ship boldly.Freedom to explore: Own experiments, propose architecture, or contribute to foundational model training.Startup speed, enterprise scale — best of both worlds. Rapid iteration and direct customer feedback.Multilingual India - first problems that push the boundaries of speech, reasoning, and personalization.
