Location: Nikol, Ahmedabad, Gujarat

Work Mode: Work From Office

We are looking for an Angular Developer who can understand product problems, work with partial requirements, use AI coding tools effectively, and take ownership of delivery.

This is a frontend-focused role, but you must have a good understanding of how the complete application works - frontend, APIs, backend, authentication, data flow, and production behaviour.

What We Need

• Good knowledge of Angular, TypeScript, JavaScript, Bootstrap 5, HTML and CSS
• Understanding of components, services, forms, routing and RxJS
• Experience with REST APIs / WebSockets
• Good understanding of frontend-to-backend flow
• Ability to identify whether an issue is frontend, API, backend, or data related
• Good debugging and problem-solving skills
• Ability to understand an existing codebase quickly
• Responsive and reusable UI development
• Git and deployment workflow knowledge
• Ability to test your own work before sending it to QA

AI-Enabled Development

We actively use AI coding tools such as Claude Code and provide the required subscriptions.

You should know how to use AI for:

• Understanding requirements
• Research
• Understanding existing code
• Technical planning
• Creating documentation
• Preparing feature/user flows
• Creating prototypes or proof of concepts
• Implementation
• Debugging
• Testing
• Code review

We do not want someone who only gives prompts to AI and waits for the answer.

You should be able to:

• Give proper context to AI
• Break problems into smaller tasks
• Validate AI-generated code
• Identify wrong assumptions
• Improve generated solutions
• Work on multiple activities in parallel
• Keep execution moving while AI tools are working

Problem-to-Execution Mindset

In our product team, requirements will not always come as a fully prepared task.

Sometimes you may receive only:

• A customer problem
• A business requirement
• A rough idea
• Partial clarity
• An expected outcome
• 
  

Your responsibility is to help convert that into something executable.

You should be able to:

Understand → Research → Ask Questions → Create Flow → Document → Prototype if Needed → Implement → Test → Verify

We are looking for people who can gradually prepare the solution, not only execute a ready-made task.

Product & Ownership Mindset

We are a product-based company.

You should understand:

• Why a feature is required
• What problem it solves
• How customers will use it
• What backend/API dependencies exist
• Edge cases and failure states
• Production impact

You should take responsibility for the complete outcome of your work.

Expected ownership:

Requirement → Planning → Implementation → Testing → Deployment → Verification → Documentation

Our culture is focused on ownership and outcomes, not simply completing assigned hours.

Flexibility & Delivery

You should be comfortable with:

• Changing priorities
• Working across different modules
• Urgent product requirements
• Learning unfamiliar technologies
• Supporting production fixes when needed
• Delivering some requirements within short timelines
• Taking responsibility for the final result

Future Scope - Agentic AI

Our future direction includes building more AI agents and automated product workflows.

Deep experience is not mandatory today, but you should be willing to learn:

• LLM APIs
• Tool calling
• MCP
• AI agents
• Agent workflows
• Automated operations

What We Value Most



• Strong fundamentals
• Learning speed
• Problem-solving ability
• Effective AI usage
• Product understanding
• Backend/API awareness
• Parallel execution
• Flexibility
• Quality
• Ownership
• Ability to grow into a Feature Owner / Product Owner

This role may not be suitable for candidates who expect fully prepared tasks, step-by-step instructions, or continuous dependency on senior developers.
