Наша компания

AI needs a new infrastructure layer. We're building it at Modal. Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now. Our customers include category-defining companies like Lovable Ramp Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale. We recently raised a $355M Series C at a $4.65B valuation, led by General Catalyst and Redpoint Ventures. We've crossed $300M+ ARR and grown fivefold since September. Our team includes creators of popular open-source projects (e.g.,Seaborn academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.

Чем предстоит заниматься

We’re looking for an Infrastructure Security Engineer to design and secure the core systems that power our platform. This role focuses on building security directly into our infrastructure—from container isolation and orchestration to identity and secrets management in a multi-tenant, cloud-native environment

You’ll work closely with engineering teams to define secure primitives and ensure our platform is resilient, scalable, and trustworthy by design

This is a hands-on, deeply technical role focused on real systems, not compliance or policy

Design and improve authentication and authorization systems across services

Implement strong service-to-service identity and least-privilege access patterns

Improve access controls across infrastructure and internal systems

Наши требования

Experience with sandboxing or runtime isolation technologies (e.g., gVisor, Firecracker, seccomp, or similar)

Familiarity with kernel-level or low-level isolation primitives

Experience securing Kubernetes or similar orchestration systems in production

Background in developer infrastructure, compute platforms, or multi-tenant systems

Experience securing cloud-native infrastructure and distributed systems in production

Background in infrastructure, backend, or security engineering

Experience working in multi-tenant or high-scale environments

Strong understanding of containerization and orchestration systems (e.g., Kubernetes or similar)

Experience designing or securing isolation mechanisms in multi-tenant systems

Solid understanding of authentication, authorization, and service identity models

Experience with secrets management and secure handling of credentials

Strong foundation in networking concepts (segmentation, service communication, access boundaries)

Дополнительно

Design and improve isolation mechanisms for multi-tenant workloads (containers, sandboxing, execution environments)

Strengthen boundaries between customers, workloads, and internal systems

Identify and mitigate risks in distributed, dynamic compute environments

Secure and harden containerized workloads and orchestration systems (e.g., Kubernetes or similar)

Improve workload isolation, scheduling boundaries, and runtime protections

Evaluate tradeoffs in multi-tenant execution models

Build and maintain systems for securely managing secrets, tokens, and credentials

Improve rotation, auditing, and access controls

Reduce secret sprawl and integrate secure patterns into developer workflows

Secure cloud environments across providers (AWS, GCP, etc.) with a focus on consistency and portability

Improve network boundaries, service segmentation, and access controls

Embed security into infrastructure-as-code and deployment systems

Work closely with product and infrastructure teams to design secure systems from the ground up

Review architecture and code for security risks and provide actionable guidance

Identify patterns in risks and drive cross-cutting improvements

Builder mentality, you design and implement, not just review

Pragmatic approach to security in fast-moving environments

Comfortable working deeply with engineers and influencing system design
