Software Engineer, Cloud Efficiency

Platform Engineering Role

Software is eating the world, but AI is eating software. We live in unprecedented times - AI has the potential to exponentially augment human intelligence. Every person will have a personal tutor, coach, assistant, personal shopper, travel guide, and therapist throughout life. As the world adjusts to this new reality, leading platform companies are scrambling to build LLMs at billion scale, while large enterprises figure out how to add it to their products. To make them safe, aligned and actually useful, these models need human eval and reinforcement learning through human feedback (RLHF) during pre-training, fine-tuning, and production evaluations. This is the main innovation that's enabled ChatGPT to get such a large headstart among competition. At Scale, our products include the Generative AI Data Engine, SGP, Donovan, and others that power the most advanced LLMs and generative models in the world through world-class RLHF, human data generation, model evaluation, safety, and alignment. The data we are producing is some of the most important work for how humanity will interact with AI. At the foundation of these products is the Platform Engineering team. In this role, you will help design and develop the foundational platforms and systems that power our cloud infrastructure, with a strong focus on cloud efficiency, cost optimization, and hosting cost attribution. This position offers wide exposure to the forefront of AI infrastructure and large-scale system design, as seen across enterprises, startups, governments, and large tech companies.

You will:

• Design, implement, and optimize core platform services with a focus on reducing cloud spend and improving resource utilization across compute, storage, and network layers.
• Collaborate closely with stakeholders and internal customers to define requirements and architect scalable, cost-efficient solutions in AWS and other public cloud environments.
• Analyze system performance and usage trends to identify opportunities for cost savings through right-sizing, autoscaling, reserved instance strategies, and architectural improvements.
• Partner with product engineering and infrastructure teams to improve orchestration, observability, and automation for efficient deployment and operation of distributed systems.
• Present insights, metrics, and recommendations on cloud usage and efficiency to engineering and business stakeholders.
• Proactively drive process enhancements and introduce new tools or frameworks that improve the balance between system performance, reliability, and cost.

Ideally you'd have:

• 3+ years of full-time engineering experience with a focus on back-end and cloud infrastructure systems.
• Deep understanding of distributed systems, cloud cost models, and AWS services (EC2, ECS/EKS, S3, Lambda, RDS, GPU instances, etc.).
• Demonstrated experience optimizing large-scale cloud deployments for performance and cost, including autoscaling, spot instance usage, and workload scheduling.
• Proven track record of independent ownership of engineering projects that delivered measurable efficiency or cost improvements.
• Excellent communication skills with the ability to explain technical trade-offs and cost implications to both engineering and non-technical audiences.
• Proficiency with containerization and deployment technologies such as Kubernetes, Terraform, and Docker.
• Familiarity with orchestration tools like Temporal or AWS Step Functions, and with both NoSQL (MongoDB) and SQL (Postgres) databases.
• Solid grasp of software engineering best practices, CI/CD (CircleCI), and infrastructure-as-code principles.
