Software Engineer, Infrastructure [Early Career]

Fireworks AI | Posted Jan 7, 2026

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 Software Engineer on our Infrastructure team, you will help design and build the core systems that power Fireworks AI’s generative AI platform. You will work on projects that support distributed AI workloads across multiple cloud environments, building tools and services that keep our platform fast, reliable, and scalable. This is an exciting opportunity for a new graduate who wants to grow as a software engineer and work hands‑on with infrastructure, distributed systems, and large‑scale machine learning platforms.

You will collaborate closely with experienced engineers, learn from technical mentors, and contribute to the next generation of AI infrastructure.

• Contribute to the design and development of scalable backend infrastructure that supports distributed training, inference, and data pipelines
• Build and maintain core backend services such as job schedulers, autoscalers, resource managers, and model serving systems
• Support performance optimization, cost efficiency, and reliability improvements across compute, storage, and networking layers
• Collaborate with ML, Dev Ops, and product teams to translate research and product needs into infrastructure solutions
• Learn and apply modern cloud technologies including Kubernetes, Ray, Kubeflow, and MLFlow
• Participate in code reviews, technical discussions, and continuous integration and deployment processes

• Bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience)
• Strong programming skills in Python, C++, or a similar language
• Solid understanding of computer systems concepts such as networking, storage, and distributed computing
• Familiarity with cloud platforms like AWS, GCP, or Azure, and containerization tools like Docker or Kubernetes
• Knowledge and interest in cloud infrastructure, distributed systems, and machine learning

• 2+ years of relevant industry experience through internships, co‑ops, or full‑time employment
