We work very closely with these customers to create specialized, rigorous benchmark datasets encompassing their most valuable and difficult knowledge work. Then we use the benchmarks to construct agentic large reasoning models, applying the same rigor to prove that the models correctly do the work. Customers access the models through a tailored application service, making their most skilled, expensive workers dramatically more productive.\nWe are an early-stage startup. Our founders previously started Voleon, now one of the world’s largest systematic investment managers, and recognized as a longstanding industry leader in applied machine learning. They bring to Rational Dynamics the same research discipline and data-driven focus that succeeded in the unforgiving, high-stakes setting of financial markets.\nAbout the role\nInstitutional investors want AI for their hardest analytical work, running inside their cloud accounts and regions, under their security and compliance rules. Rational Dynamics builds that AI. Infrastructure decides whether we can ship it: each client brings a different cloud, network, identity provider, and security review. You'll be working across client deployments, internal platform, and the research infrastructure, collaborating with product development and science teams.\nWhat you'll do\nDeploy our cloud-native platform into client clouds on AWS, GCP, and Azure, including multi-region and data-residency setups. Answer the security and architecture questions client IT teams raise\n\nCo-own existing infrastructure in AWS and GCP: EKS, Aurora Postgres, Cloud Run, networking, IAM, secrets, and GitOps delivery\n\nRun the research platform for evals and training: proprietary, open-source, managed services such as Vertex AI, SageMaker, and Bedrock, with GPU compute and storage infrastructure\n\nBuild CI/CD, observability, and alerting that let a small team ship daily and catch problems before clients do\n\nStand up rapid prototypes and harden existing prototypes for production. Give Forward Deployed Engineers tooling to do the same in client environments\n\nShare compliance (e.g. SOC 2, ISO 27001, CAIQ) and security work so audit evidence comes from how the platform runs\n\nContribute to platform development, MLOps, and internal GenAI tools\n\nManage infrastructure as code in Terraform, write down the trade-offs behind each decision, and track reliability, uptime, and cost\n\nWhat you bring\n7+ years designing and running production cloud infrastructure, 5+ of them at Senior level or above\n\nDepth in AWS or GCP, and hands-on experience with both\n\nStrong Kubernetes, Terraform, and CI/CD, including GitOps with ArgoCD or similar\n\nCloud networking and security: VPCs, private connectivity, IAM, zero-trust access, encryption, secrets, and multi-region deployments with data-residency requirements\n\nDeployments into enterprise customer clouds in finance, healthcare, defense, or another regulated industry\n\nWork under SOC 2, ISO 27001, PCI DSS, or a similar control framework\n\nCore infrastructure built from scratch at an early-stage company, or owned end to end on a small team\n\nPython and Bash for automation, and daily use of agentic coding tools such as Claude Code\n\nClear communication about designs and trade-offs with engineers, scientists, and client security teams, and comfort with shifting priorities\n\nNice to have\nAzure (AKS, VNets, Entra ID, ML/AI) or Oracle Cloud (OCI)\n\nML and GPU infrastructure: Kubeflow, Vertex AI, SageMaker, Bedrock, MLflow, Ray, KServe, Slurm\n\nInfrastructure for LLM and agent systems: model serving, vector databases, and training and eval pipelines\n\nWorkflow tools such as Temporal, Airflow, Argo Workflows, Tekton\n\nFull-stack or agentic application development, or ML and RL research\n\nGo or another systems language\n\nA record of running production systems against reliability and uptime targets\n\n“Friends of Rational Dynamics” Candidate Referral Program\nIf you have a great candidate in mind for this role and would like to have the potential to earn $7,500 to $15,000 if your referred candidate is successfully hired and employed by Rational Dynamics, please use this form to submit your referral.
