We are on the lookout for a motivated Python Developer to join our engineering team. In this role, you will help us to build our product in an efficient and solid way. To provide hands-on technical support during implementation of product features with a focus on rapid debugging, scripting, and data analysis; ensure smooth integrations and reliable deployments while improving developer productivity using AI-first tools and automation; and optimise the existing code and framework.

Responsibilities

Build and debug features for the product. Rollout issues across APIs, data transformations, and deployment workflows with rapid turnarounds.
Build and maintain Python utilities/services for validation, transformation, and automation of QC checklist execution.
Implement GenAI workflows using LangChain/OpenAI, including prompt design, tools, and guards for reliability and traceability.
Design and tune vector indexing and retrieval over PGVector for checklist content, policies, and artefacts.
Create evaluators, test harnesses, and regression suites for LLM pipelines and generated code outputs.
Instrument logs/metrics and perform root-cause analysis across data, prompts, and model outputs; document playbooks.
Collaborate with Product/CS/QA to triage tickets, reproduce issues, and ship hotfixes and safe migrations.
Harden deployments with config management, secrets hygiene, and rollback strategies for onboarding and production.
Maintain knowledge base and SOPs for integrations, data contracts, and compliance-sensitive workflows.

Requirements

4-6 years of experience with a strong Python development background.
Bachelor's in CS/Engineering or equivalent practical experience.
Experience implementing GenAI/LLM solutions in production-like settings.
Excellent debugging and communication skills.

Must-Have Skills

Python 3 x with strong software engineering and debugging proficiency.
GenAI/LLM: LangChain, OpenAI API, prompt engineering, tool/function calling, guards.
NLP utilities and text processing with NLTK or similar.
MongoDB data modelling and query optimisation for app/ops flows.
Vector databases and retrieval (PGVector on Postgres) for RAG-like patterns.
Observability and log analysis for rapid root-cause and fix-forward.
LLM orchestration with OpenAI/Gemini, including retries, timeouts, and structured outputs.
Vector retrieval with PGVector (indexing, chunking, similarity tuning, evals).
Debugging onboarding/deployment issues across configs, data, and environments

Nice To Have Skills

MLOps fundamentals (model/config/versioning, evals, CI for LLM flows).
MCP server or tool-agent patterns for internal developer workflows.
FastAPI/asyncIO for lightweight services and integrations.
CI/CD (GitHub Actions) and infra basics (Docker).
Experience with mortgage/QC/RegTech domains or checklists.
Python packaging, environments, and testing; REST APIs and JSON.
Prompt engineering basics: model limits, latency, and cost trade-offs.
Data handling with Pandas and text normalization/tokenization

Working Knowledge (Tools)

GitHub/Git; Issues/Projects; PR reviews.
JIRA/Confluence for triage and runbooks.
Postman/cURL for API validation.
VS Code with Copilot/Cursor; Python tooling (venv/poetry/pytest).
