About the Role

An Applications Engineer at Cosine works across research, engineering, product, and design to deliver advanced AI capabilities to consumers and enterprises.

You will be responsible for the core infrastructure powering Cosine’s products, including our Kubernetes environments, deployment pipelines, networking stack, cloud abstractions, and foundational platform services.

We build systems that enable rapid product iteration while maintaining operational excellence, with a strong emphasis on enterprise-grade reliability. Our work includes supporting large‑scale deployments for regulated industries, delivering hardened on‑premises installations, and ensuring secure, isolated environments for customers with stringent operational or compliance requirements

The Cloud Infrastructure engineer develops and maintains the infrastructure abstractions that allow Cosine to ship products reliably, securely, and at scale.

In this role, you will:

• Design and build development and production platforms that power Cosine products, enabling reliability and security at scale.
• Ensure our infrastructure can scale to the next order of magnitude.
• Contribute to a culture that values diversity, rigorous thinking, and open, direct communication.
• Participate in the on-call rotation to ensure reliability of the systems you build, responding to critical incidents when necessary.

You Might Thrive in This Role If You:

• Have 5+ years of experience developing or operating core infrastructure.
• Have experience running large-scale orchestration systems such as Kubernetes.
• Have built abstractions and tooling on top of major cloud platforms.
• Take pride in building scalable, reliable, and secure systems.
