Senior Backend Python Developer

Insight Global is seeking a Senior Python Backend Engineer who can own the backend architecture end‑to‑end—from API design and security to deployment and long‑term operability. You will be expected to operate independently, make sound architectural decisions, and uphold extremely high standards for code quality, security, and system reliability.

What You’ll Do
• Design, build, and maintain secure, production‑grade Python backend systems.
• Own the API layer, including contract design, versioning, governance, and documentation.
• Build and enforce intentional endpoint exposure with strict access controls.
• Integrate and operate LLM‑powered workflows using leading model providers.
• Implement robust input validation, idempotency, and fault‑tolerant API patterns.
• Deploy and operate backend services in VPS environments with proper security hardening.
• Build and maintain CI/CD pipelines supporting automated deployment, recovery, and key rotation.
• Implement logging, monitoring, and alerting to support long‑term system stability.
• Clearly document system architecture, deployments, and operational procedures.

Code Quality & Engineering Discipline
• Design modular, segmented architectures with clear boundaries and ownership.
• Build systems with fault isolation so failures do not cascade.
• Enforce strict separation of concerns across services and components.
• Implement graceful degradation—failures reduce features, not platform stability.
• Write readable, well‑documented code that can be safely maintained by other engineers.
• Avoid shortcuts entirely—if it isn’t done correctly, it isn’t done.
If your instinct under deadline pressure is to cut corners and “fix it later,” this role is not a fit.

Technical Environment
• Python‑first backend architecture.
• Secure API‑driven platform design.
• Supabase (Auth, RLS, Postgres).
• LLM API integrations (OpenAI, Anthropic, Vertex AI / Gemini).
• Dockerized services deployed to VPS infrastructure.
• Enterprise‑grade security and operational requirements.

Who Thrives Here
• Senior engineers who take pride in clean architecture and long‑term system integrity.
• People who value correctness, security, and stability over speed at any cost.
• Engineers who are comfortable owning critical systems without hand‑holding.
• Candidates who prefer autonomy, accountability, and technical depth.
