Job Description:

Why this role

You will play a key role in building modern, secure, and scalable enterprise applications that power real business outcomes. This role is ideal if you enjoy owning work end‑to‑end, shaping application foundations, and seeing your ideas move quickly from concept to production.

You will work across the full stack—backend services, APIs, frontend experiences, and local development environments—while partnering closely with product, design, data, DevOps, and business stakeholders. Your work will set the technical direction and patterns that other engineers build on.

What you’ll do

Full‑stack application development

• Design, build, and maintain enterprise applications using Python on the backend and React + TypeScript on the frontend
• Translate business and product needs into scalable, maintainable application architectures
• Establish strong foundations for application structure, security, testing, and developer experience
• Build production‑ready application skeletons and core workflows that teams can extend over time
• Define and document clear API contracts, data flows, and integration patterns

Backend & API engineering

• Build and optimize backend services using FastAPI and modern Python frameworks
• Design RESTful APIs with strong validation, versioning, and documentation
• Implement authentication and authorization using OAuth 2.0 / OIDC, RBAC, and enterprise identity providers
• Develop reliable, high‑performance services with clear error handling and observability
• Design database schemas and data access layers (e.g., PostgreSQL)

Frontend development

• Build accessible, responsive React applications using TypeScript
• Create reusable component architectures and scalable UI patterns
• Implement secure authentication flows and protected routes
• Develop intuitive interfaces for dashboards, forms, admin tools, and data‑driven experiences
• Optimize performance through modern frontend best practices

Containerization & delivery foundations

• Containerize services using Docker with secure, maintainable builds
• Set up Docker Compose local environments for multi‑service applications
• Partner with DevOps to support CI/CD pipelines and cloud deployments
• Help ensure applications are ready for cloud‑native environments

Collaboration & technical leadership

• Partner with engineers, designers, product managers, and business teams
• Lead early technical implementation and influence architectural decisions
• Share knowledge, mentor teammates, and contribute to engineering standards
• Communicate technical decisions clearly to both technical and non‑technical audiences

What you bring

Required experience

• 5+ years of professional software development experience across frontend and backend
• Strong hands‑on experience building production applications with Python
• Experience developing APIs with FastAPI or similar frameworks
• Solid experience building React applications with TypeScript
• Experience designing full‑stack applications from initial architecture to production
• Hands‑on experience with Docker and local development environments
• Experience working with authentication, authorization, and secure application patterns
• Comfort collaborating with distributed teams and multiple disciplines

Required technical skills

• Python (modern backend development and async programming)
• FastAPI (dependency injection, middleware, API design)
• React and TypeScript (hooks, component architecture, state management)
• REST API design and integration
• Authentication and authorization (OAuth 2.0, OIDC, RBAC)
• SQL databases (e.g., PostgreSQL)
• Docker and Docker Compose
• Git‑based workflows and code reviews
• Testing across frontend and backend
