If you're excited about pushing the boundaries of AI-driven product development, we want to hear from you.

At Scale, we don’t just follow AI advancements — we lead them. Backed by deep expertise in data, infrastructure, and model deployment, we are uniquely positioned to solve the hardest problems in AI adoption. Join us in shaping the future of enterprise AI, where your work will directly impact how businesses operate, innovate, and grow in the age of GenAI.

You Will:

  • Design, build, and optimize backend services for advanced AI-driven applications, focusing on AI agents, evaluation tooling, and automation.
  • Develop and refine features for Scale’s GenAI Platform, enabling businesses to build, deploy, and manage AI-driven agents with robust backend capabilities.
  • Implement scalable APIs and services in Python, leveraging frameworks like FastAPI, to support real-time AI applications and large-scale data processing.
  • Build and maintain full stack web applications using modern frameworks and technologies Next.js, React, TypeScript, and Tailwind
  • Integrate AI models and evaluation systems, working closely with ML teams to enhance agent reasoning, response quality, and decision-making.
  • Manage and optimize cloud infrastructure, ensuring high availability, performance, and security in AWS, Azure, or GCP environments.
  • Ship features at a rapid pace, maintaining high code quality, observability, and performance across backend systems.

Ideally, You Have:

  • 2+ years of experience developing backend or full-stack applications, with a strong emphasis on backend engineering.
  • Strong proficiency in Python and backend frameworks such as FastAPI or Flask.
  • Familiarity with frontend technologies (Next.js, React, TypeScript, Tailwind) with an eye for building polished, user-friendly interfaces
  • Experience making trade-offs between speed and quality in fast-paced environments
  • A passion for AI and experience working on AI-first applications, agent-based systems, or data-rich web platforms
  • Strong cloud experience (AWS, Azure, GCP), including containerized deployments (Docker, Kubernetes) and cloud services (AWS Lambda, S3, DynamoDB, etc.).
  • A track record of collaborating cross-functionally with design, product, and ML teams to bring AI-powered applications to life

PLEASE NOTE: Our policy requires a 90-day waiting period before reconsidering candidates for the same role. This allows us to ensure a fair and thorough evaluation of all applicants.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
