Software Engineer, ARC (Architecture, Reliability, & Compute) – Public Sector Engineering Team

Scale AI is seeking a highly skilled and motivated Software Engineer to join our dynamic Public Sector Engineering team. You will build and maintain internal CLIs/tools that standardize testing, deployment, and environment management; own the model inference layer (managing networking, debugging latency, tracking pricing/usage metrics for AI models); and work with Product to build integration tests that catch issues early.

• Design and implement secure, scalable backend systems for Public Sector customers, leveraging Scale's modern cloud‑native AI infrastructure.
• Own services or systems and define their long‑term health goals, while also improving the health of surrounding components.
• Improve our high engineering standards, tooling, and processes.
• Collaborate with cross‑functional teams to define and execute the vision for backend solutions, ensuring they meet the unique needs of government agencies operating in secure environments.
• Participate actively in customer engagements, working closely with stakeholders to understand requirements and deliver innovative solutions.
• Contribute to the platform roadmap and product strategy for Scale AI's Public Sector business, playing a key role in shaping the future direction of our offerings.

• At least an active secret clearance and the ability & willingness to up‑level to TS/SCI with CI Poly. This is a requirement; candidates without a secret clearance will not be considered.

• Full‑stack development experience, including modern web frameworks, programming languages, and databases; experience delivering software to air‑gapped & isolated environments is a plus.
• Cloud‑native technologies – containerization (Docker), orchestration (Kubernetes), familiarity with AWS, Azure, or GCP.
• Security‑focused experience with Federal compliance frameworks (e.g., Cloud SRG, FedRAMP, STIG).
• Strong analytical and problem‑solving skills; ability to think critically and propose innovative solutions.
• Excellent collaboration and communication skills to work with cross‑functional teams and customers.
• Adaptability and learning agility; willingness to embrace new technologies and evolve based on project requirements.
• Support working 3‑4 days a week from the DC, SF, NYC, or STL office.
