Job summary

Nscale is seeking a Senior AI Product Engineer to lead the technical design and delivery of major features within its AI services platform. You will own substantial subsystems including the API gateway, core AI capabilities, billing, and SDK tooling, driving multi-sprint projects while mentoring others.

You’ll shape technical direction, collaborate with cross-functional teams, and push for high-quality, scalable solutions across the stack.

Qualifications

5–8 years of software engineering experience.
Deep expertise in backend or full-stack development at scale (Python, TypeScript, Go, or similar).
Proven experience designing and operating API platforms or developer-facing cloud services.

Responsibilities

Lead technical design and end-to-end delivery for major product subsystems and complex features.
Own architectural decisions within your team’s domain — from API contracts to deployment strategy.
Set the quality standard: drive test coverage, observability, reliability, and incident response.
Mentor more junior engineers through design reviews, code reviews, and regular pairing.
Collaborate cross-functionally with AI platform, infrastructure, and product teams.
Identify and proactively address technical debt and scalability constraints before they become blockers.
Contribute to hiring by reviewing candidate submissions and participating in interviews.
Produce clear design documentation that enables asynchronous decision-making across the team.
