About the role
Key responsibilities & impact- Architect, develop, and maintain AI-powered applications in Python, including conversational assistants, agentic tools, and retrieval-augmented generation (RAG) systems.
- Design and optimize retrieval pipelines: embedding generation, vector search, hybrid search, and reranking against large domain-specific corpora.
- Build document ingestion and parsing pipelines that extract structured content (text, tables, figures, citations) from scientific and technical documents for downstream use by AI systems.
- Integrate structured knowledge — ontologies, controlled vocabularies, and knowledge graphs — with unstructured text to produce evidence-grounded, provenance-aware AI outputs.
- Develop and operate shared platform services that accelerate delivery of new AI applications: model gateways, agent-tool integrations, authentication, API key management, and observability.
- Lead technical design decisions and establish best practices for code quality, testing, evaluation, and deployment of AI systems.
- Provision, deploy, monitor, and troubleshoot services on Kubernetes and cloud infrastructure, including container builds, manifests, and CI/CD pipelines.
- Design and maintain relational and vector databases, including schema design, indexing, migrations, and incremental data updates.
- Define and track quality metrics for AI systems (retrieval quality, answer faithfulness, latency, cost) and drive measurable improvements over time.
- Engage directly with non-technical clients to gather requirements, clarify goals, manage expectations, and validate that delivered solutions align with their objectives.
- Translate high-level client and mission needs into actionable technical specifications and development plans.
- Mentor junior engineers and contribute to a culture of technical excellence.
- Participate in and help facilitate standups, sprint planning, and cross-team review meetings across multiple project streams.
Requirements
What you’ll need- 5+ years of professional experience in software development, with recent hands-on work building AI or ML-powered applications.

- Experience integrating large language models (LLMs) into production applications using modern agent or orchestration frameworks.
- Experience with vector databases and semantic search.
- Demonstrated experience making architectural decisions and owning technical direction for software projects.
- Experience with Docker, containerization workflows, and Kubernetes for deploying and operating production services.
- Experience with PostgreSQL and relational database design.
- Strong command of Linux development environments.
- Experience with Git/GitHub workflows, including branching, pull requests, and code review practices.
