The ideal candidate is omfortable working across frontend, backend, database, orchestration, testing, and deployment layers. They should practice structured software delivery through clear specifications, implementation plans, automated validation, and responsible use of AI\-assisted engineering workflows.

• *Key Responsibilities**

Build and maintain full\-stack application features using Next.js, React, TypeScript, Python, Django,PostgreSQL, Redis, and related technologies.

Design and implement clean, maintainable frontend components, application routes, forms, state management, and API integrations.

Develop backend APIs, domain logic, data models, validations, permissions, and service integrations.

Build reliable asynchronous workflows using job queues, orchestration frameworks, background workers, and state\-tracked execution patterns.

Write automated tests across unit, integration, component, API, and end\-to\-end levels.

Participate in architecture discussions, implementation planning, code reviews, debugging, refactoring, and technical documentation.

Use AI coding agents as part of daily development for requirement analysis, code generation, test generation, debugging, refactoring, documentation, and review.

Practice spec\-driven development by converting requirements into clear specs, acceptance criteria, implementation plans, task breakdowns, and validation steps.

Build and maintain agent harnesses that make AI\-assisted development safer and more repeatable, including context packs, reusable prompts, test fixtures, evaluation cases, coding workflows, and regression checks.

Ensure solutions are secure, observable, testable, and maintainable.

Collaborate with cross\-functional stakeholders to deliver reliable software aligned with product and engineering goals.

Responsibilities

• *Required Skills**

3 to 5 years of professional software development experience.

Strong hands\-on experience with TypeScript, JavaScript, React, and Next.js.

Strong hands\-on experience with Python and Django.

Good understanding of REST and GraphQL\-style API design.

Working knowledge of PostgreSQL, SQL data modeling, and query design.

Working knowledge of Redis or similar caching and coordination systems.

Experience with background jobs, asynchronous processing, workflow orchestration, or tools such as Airflow.

Experience with automated testing frameworks, including component, API, integration, and end\-to end testing.

Practical experience with Docker and basic Kubernetes or K3s concepts.

Strong experience using AI coding agents such as GitHub Copilot, Claude Code, Cursor, Codex style tools, or similar in real development workflows.

Ability to validate, review, and improve AI\-generated code instead of blindly accepting it.

Good understanding of authentication, authorization, role\-based access, audit logging, and secure handling of secrets.

Strong problem\-solving ability, ownership mindset, and ability to deliver maintainable software independently.

Qualifications

• *Preferred Skills**

Experience with Microsoft Entra ID, OIDC, OAuth2, or enterprise SSO integration.

Experience with Tailwind CSS, Radix\-based UI libraries, React Hook Form, and schema\-based validation.

Experience with CI/CD pipelines, deployment workflows, observability, logging, and production support.

Experience creating internal developer tools, workflow automation, dashboards, reporting interfaces, or data\-heavy applications.

Experience with agentic software engineering workflows such as plan\-confirm\-execute, tool execution, session context, task checklists, automated code review, and evaluation\-driven development.

Exposure to cloud\-native or hybrid deployment environments.

• *Success Expectations**

The engineer should be able to independently own medium\-sized full\-stack features, produce clear specs and implementation plans, write meaningful automated tests, use AI coding agents responsibly, and contribute to faster software delivery without compromising quality, security, or maintainability.
