You design applications and services, operate inference platforms and pipelines, and treat unit economics (tokens, GPU-hours, idle capacity) as engineering constraints. You partner with product, engineering, and business stakeholders to deliver working software, higher reliability, and lower cost per unit of AI value. What You Will Do Software development Design, build, and ship production services, APIs, and (where needed) user-facing interfaces. Own the full lifecycle: implementation, tests, code review, CI/CD, deploy, and maintenance. Write maintainable code in Python plus one more stack (TypeScript/Node, Go, or Java). AI engineering Build and operate production AI systems: RAG, evaluation, fine-tuning, serving, and inference optimization. Turn prototypes into reusable platform capabilities with CI/CD, eval, and governance. Cloud infrastructure Architect AWS/GCP environments with Kubernetes, Terraform, and CI/CD for apps and model pipelines. Own observability and incident response; partner on SOC 2/SOX and least-privilege IAM. Cost control Treat cloud and AI spend as an engineering problem: visibility, attribution, budgets, and reduction. Optimize GPUs, inference routing, model choice, and right-sizing; track cost per request/token and GPU idle. What We're Looking For Required 5+ years of professional software development, owning production systems (not only scripts or notebooks). Shipped backend services/APIs and production AI/ML (LLMs, RAG, serving). Strong Python plus a second stack; PyTorch, TensorFlow, or equivalent serving. AWS or GCP with Kubernetes, Terraform, and CI/CD. Proven work reducing or governing cloud/AI spend. Clear communication of technical and cost tradeoffs; you run what you build. Preferred Full-stack (React/Next.js), vector databases, inference optimization, FinOps tooling, SOX/SOC 2, Copilot/Cursor. What Success Looks Like Production software and AI with SLOs and real ownership — not demos. Reliability stays high while GPU and cloud waste trends down. Cost per unit of AI value is visible and improving; teams reuse libraries, IaC, and cost guardrails. Creating a diverse and inclusive workplace is one of Motive's core values. We are an equal opportunity employer and welcome people of different backgrounds, experiences, abilities and perspectives. Please review our Candidate Privacy Notice here .
