Full Stack Developer (Python-Heavy / Backend-Focused)

Job Description

Role Overview

\n

We are seeking a highly skilled Full Stack Developer with deep, hands-on Python backend engineering experience as the core of the role, complemented by working proficiency in ReactJS for frontend development. This is a backend-first full-stack position — candidates must demonstrate strong depth in Python services, database design, and authentication/authorization frameworks, along with a solid understanding of AI, Agentic AI systems, and the Model Context Protocol (MCP).

\n

\n

Key Responsibilities

\n

\n

\n
• Design and develop scalable, production-grade backend services using Python frameworks (FastAPI / Flask / Django)

\n

• Architect, build, and integrate RESTful APIs and backend microservices with strong attention to performance, reliability, and security

\n

• Design and optimize relational database structures using PostgreSQL / MySQL / SQL Server — including schema design, indexing strategies, query optimization, and data modeling

\n

• Implement robust authentication and authorization frameworks beyond basic JWT — including OAuth 2.0 / OpenID Connect, SSO integrations, session management, token lifecycle (refresh/rotation/revocation), and role-based / attribute-based access control (RBAC/ABAC)

\n

• Develop responsive frontend applications using ReactJS (Hooks, state management) to support backend-driven features

\n

• Integrate AI and LLM-powered capabilities into backend services, including agentic workflows and tool-calling patterns

\n

• Apply MCP (Model Context Protocol) concepts to connect AI agents with backend services, APIs, and data sources

\n

• Collaborate with cross-functional teams on API contracts, data flows, and end-to-end feature delivery

\n

• Own assigned features and technical deliverables through completion, proactively communicating progress, risks, dependencies, and blockers while collaborating effectively with team members, subcontractors, and client stakeholders

Must-Have Skills

\n

\n

\n
• Python Backend (Primary): Strong, hands-on experience building backend services with FastAPI / Flask / Django — async patterns, dependency injection, middleware, API versioning, testing, and production deployment

\n

• Databases: Deep practical experience with PostgreSQL / MySQL / SQL Server — complex queries, joins, indexing, transactions, ORM usage (SQLAlchemy / Django ORM), and performance tuning

\n

• Authentication & Security: Demonstrated depth in auth frameworks beyond JWT basics — OAuth 2.0, OIDC, SSO, RBAC, secure session handling, and API security best practices

\n

• RESTful APIs: Proven experience designing, building, and integrating REST APIs and backend services at scale

\n

• AI / Agentic AI / MCP: Solid understanding of LLM fundamentals, agentic AI architectures (planning, tool use, multi-step workflows), and the Model Context Protocol (MCP) for agent–system integration; familiarity with frameworks such as LangChain / LangGraph is a strong plus

\n

• ReactJS (Secondary): Hands-on expertise with ReactJS — Hooks, component lifecycle, and state management (Redux / Context API)

\n

\n

Candidate Profile Expectations

\n

\n

\n
• Backend-dominant full-stack engineer: roughly 80–90% Python/backend and 10–20% React in day-to-day work, must have AI experience.

\n

• Must be able to demonstrate, in technical conversation, real depth in Python, database design, and authentication frameworks — not just frontend fluency

\n

• Frontend-heavy profiles (e.g., 80/20 frontend/backend) will not be a fit for this role

\n

\n

Competencies and Interview Evaluation

\n

Interviews will also assess these competencies through examples and scenario-based questions:

\n

\n
• Ownership and Follow-Through: Completes commitments independently and takes accountability for outcomes.

\n

• Proactive Communication: Shares timely updates, risks, and blockers; resolves or escalates issues early.

\n

• Comfort with Ambiguity: Progresses independently with incomplete direction and clarifies assumptions when needed.

\n

• Confidence to Challenge and Clarify: Questions assumptions constructively and engages clients confidently when appropriate.

\n

• Professional Maturity: Works productively in any location and clearly substantiates blockers.

\n

• Team Collaboration: Collaborates effectively with team members, stakeholders, and subcontractors.

\n

\n

Resilience and Coachability: Accepts feedback professionally, adapts quickly, and improves prior work.
