Founded by the team behind PyTorch and backed by AMD, Atreides, Benchmark Capital, Index Ventures, Lightspeed, NVIDIA, Sequoia Capital, and TCV, Fireworks powers production AI with hundreds of state-of-the-art open models across text, image, embedding, audio, and multimodal workloads. Today, Fireworks is a Series D company valued at $17.5 billion, bringing together an ambitious, collaborative team that's building the future of enterprise AI. THE ROLE: As a Training Infrastructure Engineer, you'll design, develop, and maintain large-scale backend and cloud-native infrastructure to support distributed machine learning training, inference, and data processing pipelines for our generative AI platform. You'll architect scalable, resilient backend infrastructure, lead technical design discussions, mentor engineers, and establish best practices for large-scale machine learning systems. KEY RESPONSIBILITIES:

• Architect and build scalable, resilient backend infrastructure to support distributed training, inference, and data processing pipelines
• Lead technical design discussions, mentor engineers, and establish best practices for large-scale machine learning systems
• Design and implement core backend services with a focus on efficiency and low latency
• Drive infrastructure optimization initiatives for compute cost, storage lifecycle management, and network performance
• Collaborate with machine learning, DevOps, and product teams to translate research and product requirements into robust infrastructure solutions
• Evaluate and integrate cloud-native and open-source technologies such as Kubernetes, Ray, Kubeflow, and MLFlow to enhance platform reliability
• Own end-to-end systems from design to deployment, emphasizing reliability, fault tolerance, and operational excellence MINIMUM QUALIFICATIONS:
• Bachelor's degree or equivalent in Computer Science or related field plus four (4) years of experience in software engineering or related role
• 4 years of experience designing, building, and optimizing large-scale backend infrastructure and distributed data systems (e.g., PostgreSQL, MySQL, DynamoDB, Apache Spark, Apache Flink, Apache Kafka) in cloud environments (AWS, GCP, Azure, or equivalent), including cloud-native platforms, core infrastructure components, and optimization techniques (caching, indexing, sharding, replication, transactions, ACID)
• 4 years of experience with major server-side programming languages and frameworks (e.g., Python, C++, Go, TypeScript)
• 4 years of experience writing technical design documentation, leading cross-functional projects, and collaborating with cross-functional teams to achieve business impact
• 3 years of experience developing and maintaining data processing and API systems, including client-server communication frameworks (e.g., gRPC, Thrift)
• 3 years of experience conducting A/B testing and scientific experimentation (e.g., Statsig, Meta Deltoid, Optimizely) to measure software impact
• 3 years of experience conducting coding interviews and providing systematic feedback for engineering candidates
• 2 years of experience with cloud-native tools and infrastructure, such as Docker and Kubernetes
• 2 years of experience defining and implementing data-driven metrics to support company or team goals How to Apply: Submit resume and apply online at http://www.fireworks.ai/careers and search for job by title.
