Software Engineer Platform Infrastructure

You will design, build, maintain, and own the critical infrastructure systems that enable AI engineering workloads. You will develop a gVisor-based runtime environment and a high-throughput sandbox scheduler across multiple cloud providers. You will harden infrastructure against failures, downtime, and slowdowns; plan and implement network infrastructure and cloud strategy; and drive reliability improvements across engineering. You will ensure the infrastructure remains fast, stable, secure, and able to scale under unpredictable global load.

Responsibilities

• Design, build, and maintain systems that enable the AI product.
• Develop a gVisor-based runtime environment for agentic workloads.
• Build a high-throughput sandbox scheduler across multiple cloud providers.
• Harden infrastructure against failures, downtime, and slowdowns.
• Ensure infrastructure does not become a bottleneck as usage grows.
• Plan and implement network infrastructure and cloud strategy.
• Identify and drive reliability improvements across engineering.

Requirements

• Demonstrate deep experience building and operating production infrastructure as a Software Engineer, Systems Engineer, Site Reliability Engineer, or similar.
• Write clean, performant code and understand systems from the API layer to the runtime.
• Understand container orchestration and sandboxing beyond configuration, including schedulers, runtimes, and isolation boundaries.
• Demonstrate strong proficiency in Go, Rust, C++, or a similar systems-oriented language.
• Demonstrate experience designing services for high throughput and unpredictable load at a global technology company or scale-up.
• Balance security, stability, and speed trade-offs.
• Be based in Stockholm or be ready to relocate for an on-site role five days per week.
