Join Blossom

We're looking for a curious and detail-oriented AI Engineer who is eager to grow in the fintech space. If you have hands-on experience building production AI systems and want to own real intelligent products from day one with mentorship and a team that will help you level up this role is for you.
About the Role
We're looking for an AI Engineer who thrives at the intersection of applied machine learning and production software engineering. You will design, build, and operate intelligent systems powered by large language models from agentic workflows and RAG pipelines to multi-step LangGraph agents deployed reliably on AWS.
This is a hands-on engineering role. You will own features end-to-end: collaborating with product and data teams to define requirements, implementing solutions with clean Python, and shipping them to production.



You care about observability, cost efficiency, and measurable agent quality not just getting demos to work.
What You'll Do
- Design and build production LLM-powered features, including multi-step agentic workflows, RAG pipelines, and tool-augmented assistants.
- Develop and maintain LangGraph agents with well-defined state management, checkpointing, and human-in-the-loop patterns.
- Integrate AWS Bedrock to invoke foundation models (Claude and others), configure Guardrails, and leverage Knowledge Bases and Agents.
- Architect and operate AI workloads on AWS across Lambda, ECS/Fargate, S3, DynamoDB/RDS, and CloudWatch.
- Set up and manage MCP (Model Context Protocol) servers and clients to extend agent capabilities with external tools and data sources.
- Own prompt engineering and evaluation: define metrics, run experiments in Braintrust, LangSmith, or Promptfoo, and iterate systematically.
