About Nexus

Nexus is building a world supercomputer by leveraging the latest advancements in AI, cryptography, engineering, and science. Our team of world-leading experts is developing and deploying the Nexus Layer 1 blockchain and Nexus zkVM (zero-knowledge virtual machine) in support of our mission to enable the Verifiable Internet.

Nexus raised $25M in Series A funding from Lightspeed, Pantera, Dragonfly, SV Angel, and more.

We are headquartered in San Francisco, and this role will be in-person with the rest of the Nexus team.

AI Software Engineer, Inference
We’re looking for an AI Software Engineer focused on Inference to help us bring powerful AI models to life — fast, efficient, and at scale. This role is all about building the systems that deliver real-time predictions, keeping latency low and performance high. If you love optimizing ML workloads and making complex systems run smoothly in production, this one's for you.

At our startup, speed matters — not just in how our models perform, but in how quickly we learn, ship, and grow. You’ll be a core part of the engineering team, collaborating closely with researchers and product engineers to build scalable inference systems that support everything we do.

Responsibilities

• Design and optimize lightning-fast inference pipelines for both real-time and batch predictions

• Deploy and scale machine learning models in production across cloud and containerized environments

• Leverage frameworks like TensorFlow Serving, TorchServe, or Triton to serve models at scale

• Monitor performance in the wild — build tools to track model behavior, latency, and reliability

• Work with researchers to productionize models, implement model compression, and make inference as efficient as possible

• Solve problems fast — whether it’s a scaling bottleneck, a failed deployment, or a rogue latency spike

• Build internal tools that streamline how we deploy and monitor inference workloads

Requirements 

• 3+ years of experience in software engineering, preferably with exposure to ML systems in production

• Strong skills in Python, Go, or Java, and a solid understanding of system performance fundamentals

• Experience with containerization (Docker, Kubernetes) and deploying services in the cloud (AWS, GCP, or Azure)

• Solid understanding of model serving architectures and techniques for optimizing latency and throughput

• Comfort with performance tuning and profiling of ML model execution

• A practical mindset and eagerness to own production systems from build to run

• Embrace AI as a core part of how you work, think, and build.

Bonus Points

• Experience with hardware acceleration for inference (GPUs, TPUs, etc.)

• Familiarity with real-time data processing and streaming tools

• Hands-on with edge deployment (mobile, embedded, etc.)

• Contributions to open-source projects in model serving or ML infrastructure

Benefits

• Competitive salary and generous equity compensation

• Health insurance for employees and their dependents

• Daily lunch and dinner provided at SF headquarters

• Company-paid travel to events and conferences

Nexus is committed to diversity in our workforce and is proud to be an Equal Opportunity Employer (EEO).
