Senior Python/AI Engineer

Compustaff is partnering with a leading global asset manager to hire a Senior Python/AI Engineer for its Fixed Income Credit team. You'll build production-grade AI applications and robust Python services that turn unstructured financial data into real insight for analysts and portfolio managers. The role is based in Donegal, with 2-3 days required at the office.

Why this role

- Real impact: Ship AI features that directly influence credit research and investment decisions.

- Modern stack: AWS Bedrock, Python/FastAPI, RAG/GraphRAG, vector databases, and strong automated testing.

- Engineering culture: Clean code, measurable quality, and shipping to production—regularly.

What you'll do

- Design and deliver advanced AI applications on AWS Bedrock (including Converse API interfaces).

- Build high-performance Python/FastAPI services with comprehensive automated tests.

- Implement RAG/GraphRAG architectures using knowledge graphs and vector DBs (e.g., OpenSearch, Neptune Analytics).

- Create scalable API endpoints for model serving; optimize latency, throughput, and cost.

- Develop evaluation frameworks and load testing (e.g., Locust) to ensure reliability at scale.

- Establish CI/CD test automation with strong coverage, integration tests (pytest, unittest, testcontainers).

- Apply API security best practices across microservices.

What you'll bring

- 3+ years building AI/ML services and Python backends in production.

- Strong software engineering with FastAPI and RESTful design.

- Hands-on with pytest/unittest, testcontainers, and performance testing (e.g., Locust).

- Experience implementing RAG/GraphRAG for enterprise use cases.

- Proficiency with AWS Bedrock (model deployment & integration) and vector/graph data stores.

- Ability to design evaluation frameworks, automate tests, and manage token/cost optimisation for AI services.

Nice to have

- FastMCP experience for high-performance API services.

- Domain exposure in financial services or other regulated industries.

- Hybrid approaches combining rule-based logic with modern ML.

- Multi-modal models and async Python patterns.

- API gateway architecture, microservices, Lambda/S3/ECS, containers.

- Bachelor's degree in CS, Statistics, Finance, Economics or similar.
