Senior Infrastructure Engineer

About the Role

We’re looking for a Senior Infrastructure Engineer to help us design, build, and scale the foundational architecture that powers our next-generation AI systems. This role is ideal for someone who thrives in a fast-paced, engineering-driven environment and finds joy in creating robust, elegant systems from scratch.

What You’ll Do

• Build and maintain stable, scalable, and highly available compute infrastructure, spanning cloud (AWS) and bare metal environments.
• Design and operate efficient storage solutions for large-scale AI training datasets and checkpoints.
• Develop high-performance online inference systems, optimizing for diverse GPU environments (e.g., H100, B200).
• Automate infra workflows to maximize reliability, observability, and performance across our platform.
• Collaborate closely with AI researchers and backend engineers to support evolving model deployment and experimentation needs.
• Lead and contribute to internal tooling, CI/CD pipelines (e.g., GitHub Actions), and monitoring infrastructure (e.g., Grafana, Prometheus, OpenTelemetry).

What We’re Looking For

• 3 years+ of experience in DevOps / SRE / Infra.
• Strong programming ability in Python or Golang (must be proficient in at least one).
• Production-level experience with Kubernetes in daily operations.
• Deep understanding of modern DevOps / SRE / Infra principles, especially around scalability, automation, and fault-tolerance.
• Hands-on experience with AWS services (e.g., EC2, S3, EKS, IAM, RDS, CloudFront).
• Ability to work independently, lead projects, and become a subject matter expert.
• Strong communication skills and a collaborative, self-motivated mindset.

Nice to Have

• A tinkerer’s spirit - you enjoy hacking, experimenting, and building things for fun or learning. Examples we value:
• Running your own home lab or mini data center.
• Building clever side projects or open-source tools.
• Writing high-quality technical articles or contributing to public repos.
• Developing lightweight, efficient tooling for infra monitoring or ops.
• Contributions to the open-source community or prior experience maintaining open/closed source systems.
• Familiarity with model training workflows (e.g., LLMs, GPUs, large data IO).
• Interest in working directly with AI researchers and understanding model performance trade-offs.

• Brain: We value intelligence and the pursuit of knowledge. Our team is composed of some of the brightest minds in the industry.
• Heart: We care deeply about our work, our users, and each other. Empathy and passion drive us forward.
• Gut: We trust our instincts and are not afraid to take bold risks. Innovation requires courage.
• Taste: We have a keen eye for quality and aesthetics. Our products are not just functional but also beautiful.

• Competitive salary, equity, and benefits package.
• Opportunity to work with a talented and passionate team at the forefront of AI and 3D technology.
• Flexible work environment, with options for remote and on-site work.
• Opportunities for fast professional growth and development.
• An inclusive culture that values creativity, innovation, and collaboration.
• Unlimited, flexible time off.
