Python Developer

We 7re modernising a complex back end and need senior developers who can move fast with quality leveraging AI augmented codingtools (Claude, GitHub Copilot, CodeLlama/Codex, etc.) to accelerate analysis of the current system and delivery of well tested, maintainable features. You 7ll pair program frequently, practice TDD, and own your code from dev to prod.

Responsibilities

• Build & ship Python services: Design, implement, and maintain backend services/APIs (Django or FastAPI), with clear boundaries, strong typing, and robust observability.
• Use AI for the heavy lifting: Employ AI tools to analyse legacy code, draft migration plans, generate scaffolds/tests, and speed up refactors while applying human judgment to validate outputs and manage risks.
• TDD as standard: Write tests first and automate end to end validation (e.g., Playwright for web flows; pytest for unit/integration).
• Pair program often: Co design and co code to raise quality, share context, and keep momentum; rotate pairs for knowledge spread.
• Own the path to production: Build and maintain CI/CD pipelines; configure environments; instrument services (logging/metrics/traces); champion release health.
• Provision infra as code: Use Terraform to define cloud resources; keep everything reproducible and reviewable.
• Data & persistence: Model and optimise relational stores (SQL), write migrations, and tune performance.
• Engineering rigor: Code reviews, ADRs, threat modelling, performance profiling, and continuous refactoring.
• Team leadership: Mentor peers, help refine tickets, contribute to roadmaps, and uphold engineering standards.

What you 7ll bring

Must haves

• 5 67 years professional software development experience, with a very strong Python background.
• Hands on experience with AI augmented coding (e.g., Claude, GitHub Copilot, Codex), including practical understanding of pros/cons (context windows, hallucinations, privacy, licensing, code provenance, and when not to use AI).
• Solid web service development with Django or FastAPI.
• Strong SQL skills (schema design, migrations, query optimisation).
• Proven TDD mindset (unit/integration) and UI/E2E testing with Playwright.
• DevOps fluency: build/deploy your own pipelines (GitHub Actions/Azure DevOps/GitLab CI, etc.), containerisation (Docker), environment configuration, and infrastructure as code with Terraform.
• Comfortable with pair programming as a default practice; excellent communication and collaboration.
• Bias for action: you work quickly, test thoroughly, and keep quality high.

Nice to haves

• Java experience (helpful for legacy interop; not essential).
• Cloud experience (AWS/Azure/GCP), including networking, secrets, and observability stacks (OpenTelemetry/Prometheus/Grafana).
• Security by design: OWASP, dependency scanning, SBOMs, and least privilege IAM.
• Performance tuning at API/database layers.
