About the Role We’re looking for a Senior Python Engineer to help shape the next generation of intelligent products on our ML/AI team. You’ll design and build the systems that bring machine learning and generative AI out of the lab and into the hands of real users, from scalable cloud-native backends to the APIs and interfaces that make AI accessible. This isn’t a research-only role. You’ll own the full lifecycle, prototyping new ideas, architecting production-grade services on Google Cloud Platform, and shipping features that customers interact with every day. If you love working at the intersection of software engineering and AI, and you want your code to have an immediate, visible impact, this is your role. Responsibilities: Build & Ship AI-Powered Products - Design, develop, and deploy production ML/AI services end-to-end, from model integration through client-facing APIs. - Build event-driven, real-time architectures using Cloud Functions, Cloud Run, Kubernetes, Pub/Sub, and similar GCP services. - Integrate transformer-based models and LLMs into scalable inference pipelines, handling prompt engineering, output formatting, and graceful error recovery. - Write clean, well-tested Python backends that power seamless full-stack experiences. Own the Architecture - Lead design sessions and whiteboarding, translating product requirements into robust technical architectures. - Drive projects from concept to production with minimal handholding; set pace, raise the bar. - Champion engineering best practices: CI/CD, observability, testing, infrastructure-as-code. Collaborate & Communicate - Partner closely with other engineers, product owners, and data scientists to align priorities and deliver iteratively. - Translate AI concepts into clear, actionable plans so non-tech stakeholders can rally behind. - Participate in code reviews, architecture discussions, and knowledge-sharing sessions. Technical Requirements: Must-Haves: - 4–6+ years of professional backend or full-stack software engineering experience with a strong Python focus. - Proven track record designing and deploying cloud-native applications (GCP strongly preferred; AWS/Azure considered). - Hands-on experience building resilient, event-driven microservices and RESTful/gRPC APIs. - Solid understanding of containerization (Docker), orchestration (Kubernetes), and serverless paradigms. - Strong experience with SOLID design principles. - Good communicator who thrives in cross-functional, agile teams. - Comfort using AI tools to accelerate development throughput. - Advanced English communication skills. Good to Have: - Experience deploying and serving ML models or LLMs in production. - Familiarity with prompt engineering, retrieval-augmented generation (RAG), vector search, or fine-tuning workflows. - Exposure modern AI orchestration frameworks (LangChain, Google ADK, etc). - Experience with infrastructure-as-code tools (Terraform, Pulumi) and CI/CD pipelines. - Bachelor's degree in computer science, or a related field (or equivalent practical experience).
