We are looking for
We are looking for a top Machine Learning Software Engineer to bridge the gap between complex data pipelines and production-grade, user-facing software.
If you are a builder who cares just as much about system architecture and user empathy as you do about model inference, you belong here.
Who you are
- You have User Empathy: You don't just build to spec; you care deeply about the end-user experience and the real-world value your code delivers.
- You are a Problem Solver: You have a deep engineering mindset, remain open-minded to new paradigms, and love untangling complex architectural knots.
- You are an Engineer first: You have a strong background in software development (ideally full-stack and cloud). You aren't a pure Data Scientist who lives exclusively in Jupyter notebooks; you know how to build, test, and ship resilient software.
Your basic qualifications
- Core: Python (Advanced).
- Data & APIs: PostgreSQL, FastAPI, GraphQL.
- Cloud: AWS (S3, Bedrock, Athena, Lambda—strong experience here is a massive plus).
- Workflow: High productivity, AI-assisted coding tools a plus, and modern CI/CD pipelines.
