Cotidal
AI-focused supercomputing infrastructure provider
Supercomputing built for AI.
Cotidal is building the computing infrastructure that AI companies and research labs need to train and run their models. Starting with TPUs, we design the hardware and software together around their workloads, with the goal of making powerful AI chips easier to use at scale.
Our mission is endless compute for humanity. Over time, we want customers to choose across chip stacks without rebuilding their infrastructure.
We’re looking for software and systems engineers to help build Cotidal’s compute platform. Our work spans accelerator clusters, distributed infrastructure, training and inference systems, and customer products.
You’ll join a small engineering team building these systems from their earliest deployments through production scale. We welcome engineers with deep experience in one area who enjoy learning unfamiliar systems and working across boundaries. You’ll work closely with teammates and customers to understand problems, make technical decisions, and carry projects through to working software and reliable systems.
You’ll help shape the projects you work on, drawing on your strengths, experience, and interests to tackle the problems ahead. The areas below offer examples of where you could contribute, with room to work across them. We don’t expect experience in all of them.
HPC & Cluster Systems: Build and operate the accelerator clusters that power demanding AI workloads. Work across Linux, networking, storage, and hardware health to bring systems online, diagnose failures, and keep large fleets reliable and efficient.
Software Infrastructure & Control Plane: Build the distributed systems that turn individual machines into a compute platform. Work on provisioning, scheduling, resource management, and orchestration, making complex infrastructure reliable as the fleet and its workloads grow.
Training, Inference & Performance: Help AI teams get more from their compute. Work on training and inference frameworks, model serving, and performance across accelerators — from understanding a workload’s bottlenecks to improving how it runs in production.
Product Engineering: Build the products through which customers use Cotidal. Work across interfaces, APIs, and backend systems, turning customer needs into useful software and owning features from the first conversation through production.
You’ve built things people rely on—and been there when they broke, outgrew the original design, or got used in ways you never expected.
You follow a problem wherever it leads: dive deep into the stack, runtime, or hardware to understand a bottleneck, then zoom out to see whether fixing it solves the bigger problem.
When the path isn’t clear, you build something to find out—a prototype, a benchmark, a small working slice. You use what you learn to decide what deserves a bigger investment.
You have opinions about how systems should be built, can explain the tradeoffs, and have changed your mind when the evidence called for it.
Experience in one or more of the following:
Kubernetes controllers, schedulers, or distributed systems handling resource allocation, tenant isolation, and failure recovery.
Bare-metal provisioning and hardware bring-up; RDMA, collective communication, or distributed storage.
Training or inference optimization with PyTorch, JAX, XLA, vLLM, or SGLang—especially batching, KV caches, quantization, and parallelism.
Building complex, user-facing products across the full stack, with strong product judgment and attention to interaction design, performance, and reliability.
Hands-on experience with GPU, TPUs, Trainium, Instinct, Jalapeño, WSE, or other accelerator architectures.
Work across cluster infrastructure, fleet software, AI workload performance and customer-facing APIs and workflows. Agree the starting problem and ownership boundary with the team.
Own work from design through delivery, working directly with the founders. Help shape the foundations of an early company through direct discussion and work across disciplines.
Location: Palo Alto, in person.
Compensation: Competitive salary and equity.
Visa sponsorship: We sponsor work visas and help you navigate the process.
Benefits: Medical, dental, and vision coverage, unlimited PTO, and relocation support as needed.
Cotidal builds specialized AI compute infrastructure, creating supercomputers for training and running large AI models for leading AI companies and research labs. Its approach pairs hardware and software in a single design, engineering silicon, code, and data-center deployment together to maximize performance for AI workloads; initially it centers on TPUs with a goal of supporting multiple chip stacks later. This holistic co-design differentiates Cotidal from vendors that sell hardware or software separately, aiming for hardware-agnostic efficiency as chip tech evolves. Its goal is to speed breakthroughs in AI by providing scalable, integrated compute for fields like medicine, physics, and robotics.
