Senior Software Engineer - Cloud & Platform Security

Who we are Pronto AI is a global leader in commercializing autonomous vehicle (AV) technology, deploying Autonomous Haulage Systems (AHS) that automate operations in mines, quarries, and construction sites worldwide. While much of the industry remains in R&D, we deliver real, production-ready autonomy that is already operating in the field. We are on a mission to make mining operations safer, smarter, and more efficient through cutting-edge technology, and we are building toward becoming the world’s first profitable AV technology company. What you’ll do As a Senior Software Engineer focused on Cloud & Platform Security, you’ll work directly with our Infrastructure team to secure the systems that manage and control our fleet. Rather than duplicating the team’s existing cloud and Kubernetes ownership, you’ll bring deep security expertise across identity, secrets, network segmentation, and the fleet-management and remote-vehicle-control APIs that represent some of the highest-impact systems in our environment. Design and enforce least-privilege access across cloud environments, with a focus on service identities and other non-human access. Strengthen secrets and credential management using Vault, cloud KMS, or equivalent systems. Threat model and review fleet telemetry, dispatch, and remote-vehicle-control APIs, including authentication, authorization, rate limiting, and replay protection. Design and improve network segmentation to isolate fleet-management, dispatch, and remote-control systems from corporate and consumer-facing environments. Partner with Infrastructure engineers during architecture and design reviews to identify security requirements before services reach production. Review and improve Kubernetes security controls, including RBAC, network policies, and pod security standards, while partnering with the Infrastructure team that owns the platform. What we’re looking for We’re looking for a hands-on security engineer who can work as an embedded partner to an experienced Infrastructure team. You should be comfortable going deep on cloud and platform security, influencing technical decisions, and helping engineers build secure systems without operating as a gatekeeper.. Basic qualifications 5+ years of experience in cloud, infrastructure, or platform security. Hands-on experience working with production Kubernetes environments. Strong understanding of API security, including OAuth/OIDC, mTLS, authentication, and authorization design. Experience designing or reviewing both coarse-grained and fine-grained authorization models. Experience with secrets-management systems such as HashiCorp Vault, cloud KMS, or equivalent technologies. Experience managing or securing non-human identities and service-to-service access. Strong understanding of network segmentation and access boundaries in cloud environments. Demonstrated ability to work closely with infrastructure and software engineering teams and influence security decisions through collaboration. Nice to have Experience securing real-time or low-latency control-plane systems. Familiarity with service mesh security and workload-to-workload mTLS using Istio or similar technologies.
