As an intern, you will be working closely with our experienced engineering team to design, develop, and deploy the top open AI models at scale. This is an excellent opportunity to gain hands-on experience in building scalable and efficient software systems, while working on cutting-edge AI models and algorithms. ## What You’ll Do - Collaborate with the engineering team to design, develop, and test inference solutions for the top AI models. - Implement and optimize AI models using Python, C++, CUDA, NCCL - Monitor and maintain the live service. - Work on feature development, bug fixing, and code reviews to ensure high-quality software delivery - Participate in daily stand-ups, code reviews, and design discussions to ensure seamless collaboration - Stay up-to-date with industry trends and advancements in AI and machine learning - Try new things - Ship stuff ## What You Bring - Currently pursuing a Bachelor's or Master's degree in Computer Science, Computer Engineering, or a related field - Strong fundamental knowledge in computer science, including data structures, algorithms, and software design patterns - Proficiency in Python, including experience with AI/ML libraries and frameworks (e.g., NumPy, pandas, SciPy, TensorFlow, PyTorch) - Familiarity with AI models, Transformers and Diffusers - Experience with version control systems (e.g., Git) and agile development methodologies - Excellent problem-solving skills, with the ability to debug and optimize code - Strong communication and teamwork skills, with the ability to effectively collaborate with cross-functional teams ## Why DeepInfra - Work on cutting-edge AI model serving - the systems that power the next generation of LLMs and multimodal models. - Small team, huge impact: your work ships directly to customers. - Opportunity to learn from engineers building high-performance inference at scale. - Fast-paced environment with ownership, autonomy, and end-to-end responsibility. ## How we work Three traits define the people who thrive here, and this role leans on all three. Initiative. We take ownership and step in where we can add value. Whether it’s starting something new, improving what exists, or helping move ideas forward, we aim to be proactive and thoughtful in how we contribute. Drive. We’re energized by hard problems. Building AI infrastructure is complex, and we lean into that. We care about doing things well, moving fast, and continuously improving — because solving meaningful challenges is what motivates us. Grit. Things don’t always work on the first try — and that’s expected. We stay persistent, adapt quickly, and learn as we go. We take setbacks seriously, but not personally, and use them to get better. ## About Deep Infra Inc. ## Company Overview - **One-liner**: DeepInfra operates a purpose-built AI inference cloud that provides developer-friendly APIs for running open-source and proprietary machine learning models at scale. - **Entity Type**: Private (Series B) - **Headquarters**: Palo Alto, California, United States - **Founded**: September 2022 - **Founders**: Nikola Borisov (CEO), Georgios Papoutsis, and Yessenzhar Kanapin ## Core Business - **Primary industry/industries**: Artificial Intelligence / Machine Learning Infrastructure - **Target customers**: B2B; startups, enterprises, and developers needing high-throughput, low-latency AI model inference. - **Mission or purpose statement**: To provide a reliable, non-lock-in inference provider built on open-source models, giving companies full control over their AI stack with purpose-built, inference-optimized infrastructure from the GPU hardware layer up to the API. ## Products & Services - **DeepInfra Inference API**: A developer-friendly, OpenAI-compatible API offering access to over 100 open-source and proprietary models (including GLM-5.3-Flash, Kimi K3). Features pay-as-you-go pricing with no long-term contracts. - **Private GPU Clusters**: Dedicated NVIDIA B300 GPU clusters for enterprise customers, available on 5-year terms at significantly below-market rates (e.g., $1.98/GPU-hr vs. $6.50/GPU-hr on public cloud). Scales from 256 to 5,000 GPUs. - **Custom Model Hosting**: A service allowing customers to deploy their own models on DeepInfra’s optimized infrastructure. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed for the Series B round. - **Key Metric (Funding)**: Total funding of approximately **$153.6M** across 5 rounds, according to LinkedIn. The most recent round was a **$107M Series B** co-led by 500 Global and Georges Harik, with participation from A.Capital Ventures, Crescent Cove, Felicis, NVIDIA, Peak6, Samsung Next, Supermicro, and Upper90. - **Notable Investors/Partners**: NVIDIA, Felicis, 500 Global, Samsung Next, Supermicro, Peak6, A.Capital Ventures, Crescent Cove, Georges Harik. - **Growth Signals**: - Processes over **four trillion tokens per week**. - **25x token volume growth** since Series A. - Workforce grew **312.5% year-over-year** (to 27 employees). - LinkedIn follower count grew **160.7% Year-over-Year**. - Revenue estimated by LinkedIn at **$3.8M annually** (likely early-stage metric). ## Competitive Advantages - **Vertically Integrated Infrastructure**: Unlike many competitors that run on top of public clouds, DeepInfra owns and operates its own GPU hardware in US-based data centers, giving it direct control over cost and performance. - **Cost Leadership**: Advertising pricing up to 70% cheaper than public cloud alternatives for dedicated clusters (e.g., $1.98/GPU-hr for B300). - **Enterprise Security & Compliance**: SOC 2 and ISO 27001 certified with a strict zero data retention policy, ensuring data privacy. - **Open-Source Focus**: DeepInfra is built on the belief that open-source models are the future, offering a wide variety (100+ models) without vendor lock-in. ## Strategic Focus - **Scale and Product Expansion**: The Series B funding is specifically earmarked for scaling the "inference cloud," likely meaning expanding GPU capacity and geographic footprint. - **Supporting Agentic and Complex Workloads**: The platform is optimized for long-horizon agent tasks, coding, and complex multimodal workflows, indicating a focus on the most compute-intensive and emerging AI use cases. - **Enterprise Deployments**: The offering of dedicated, long-term GPU clusters signals a push for larger, more stable enterprise contracts. ## Why Work Here - **Culture & Impact**: DeepInfra operates at the core of the AI infrastructure boom. Employees get to work on hard performance engineering problems (every millisecond matters) that directly affect how AI products are built and scaled across the world. - **Engineering DNA**: The leadership previously built the backend infrastructure for imo messenger, a platform with 1 billion+ downloads. The current team is engineering-heavy (45% of staff in technical roles) and is distributed across the US and Europe (Bulgaria, Poland, Turkey, Serbia). - **Workplace**: The primary office is in Palo Alto, CA, with an **OnSite Workspace** policy (employees work from the physical office). - **Perks & Growth**: As a high-growth startup (312.5% YoY headcount growth), DeepInfra offers significant opportunities for ownership and rapid career advancement. ## Sources 1.
