Python Flask React Jobs in Delaware (NOW HIRING)

Key Responsibilities

• Lead the end-to-end technical design and development of full-stack applications, with emphasis on the front-end/UI platform and its supporting APIs.

• Own the micro-frontend (MFE) strategy module boundaries, shared shell, and Webpack & Module Federation setup across teams.

• Define the UI design system component libraries, design tokens, and how they're sourced from Figma and propagated to code.

• Set standards for state management across React applications and for CSS architecture at scale.

• Own accessibility (ARIA/WCAG) compliance delivery across all UI surfaces.

• Define UI performance budgets and drive performance/error monitoring rollout in production.

• Design, build, and manage robust RESTful APIs (OpenAPI 3.0) and service integrations, including versioning, lifecycle, and governance.

• Set the strategy for contract testing across producing and consuming teams.

• Direct authentication/authorization delivery using OAuth/OIDC and enforce OWASP security standards for both UI and APIs.

• Design and optimize database queries, indexing, and data access strategies (schema/data modelling not required for this role).

• Set the test automation strategy (Playwright) and quality gates for UI/API releases.

• Ensure application scalability, availability, reliability, and security.

• Collaborate with product, engineering, DevOps, and other stakeholders to translate business requirements into technical solutions.

• Provide technical leadership, code reviews, and mentorship to development team members; run day-to-day delivery of the team including sprint commitments and real-time unblocking.

• Drive engineering best practices including clean code, testing, CI/CD, monitoring, and documentation.

• Champion effective use of AI-assisted development tools (e.g., GitHub Copilot) across the SDLC coding, code review, testing, and documentation and set adoption practices for the team.

• Identify technical risks, bottlenecks, and architectural improvements and provide effective solutions.

• Participate in effort estimation, sprint planning, technical roadmaps, and delivery planning.

Required Skills

• Expert, hands-on React and TypeScript skills non-negotiable.

• Proven, hands-on experience with micro-frontend architecture using Webpack and Module Federation non-negotiable.

• Understanding of software architecture, including scalable, API-based, service-oriented system design.

• Strong hands-on Node.js experience for API and backend services.

• Strong experience designing and developing REST APIs (OpenAPI 3.0) and integrating third-party services; API versioning, security, documentation, and performance best practices.

• Experience with state management patterns (Redux, Context, signals, or equivalent) and CSS architecture at scale.

• Experience working with a UI design system (component libraries, design tokens) and Figma hand-off workflows.

• Working knowledge of ARIA/accessibility (WCAG) standards.

• Solid understanding of OAuth/OIDC and OWASP security practices for both front-end and APIs.

• Experience writing contract tests for APIs.

• Comfortable writing and optimizing SQL queries against relational databases (e.g., PostgreSQL, MySQL) data modelling/schema design not required.

• Experience with CI/CD pipelines, automated testing (Playwright or similar), and production deployment practices.

• Practical, hands-on experience using AI-assisted coding tools (e.g., GitHub Copilot) in day-to-day development and across the SDLC.

• Experience mentoring and guiding software engineers.

• Strong problem-solving, communication, and stakeholder management skills.

Preferred Qualifications

• Experience with Python for backend/API development (added advantage, not required) frameworks such as FastAPI, Django, or Flask.

• Working knowledge of AWS (compute, storage, database, networking, security, monitoring services) preferred, not mandatory.

• Experience with containerization and orchestration technologies such as Docker and Kubernetes.

• Experience implementing UI A/B testing.

• Exposure to error/performance monitoring tooling (DynaTrace RUM, or similar).

• Experience working in Agile/Scrum development environments.

• Prior work in a regulated or enterprise design-system environment.

Experience

8+ years of overall software development experience, with significant experience in front-end/full-stack development, React/TypeScript, micro-frontend architecture, and API design/development.
