At Fireworks, we're building the future of generative AI infrastructure. Our platform delivers the highest-quality models with the fastest and most scalable inference in the industry. We've been independently benchmarked as the leader in LLM inference speed and are driving cutting-edge innovation through projects like our own function calling and multimodal models. Fireworks is a Series C company valued at $4 billion and backed by top investors including Benchmark, Sequoia, Lightspeed, Index, and Evantic.

We're an ambitious, collaborative team of builders, founded by veterans of Meta PyTorch and Google Vertex AI.

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.

• 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, Dev Ops, 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

• 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, Type Script)
• 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

• Solve Hard Problems:
  Tackle challenges at the forefront of AI infrastructure, from low-latency inference to scalable model serving.
• Build What's Next:
  Work with bleeding-edge technology that impacts how businesses and developers harness AI globally.
• Ownership & Impact:
  Join a fast-growing, passionate team where your work directly shapes the future of AI—no bureaucracy, just results.
• Learn from the Best:
