Our team is looking for a Senior Fullstack (Golang+React) Developer for one of our clients.

Location: Noida, India

Work mode: Office

Working time zone: IST

Client: our client is one of the TOP-5 global management consulting firms, considered to be among the most prestigious ones in the world. Adding a project with one of the world’s most prestigious consulting firms to your portfolio is the kind of line that carries weight on your CV for the rest of your career.

You will work directly with the client’s engineering and product leads — not through a layer of coordinators. The platform is the technology backbone of the client’s commercial operations, used by Fortune-500 enterprises. Your code goes into it.

You will be responsible for designing and developing complex, scalable web applications from end-to-end, leveraging a diverse polyglot stack including Go, and/or JavaScript with React. This role requires a balance of hands-on coding and architectural design.

What you will get hands-on with:

Building high-concurrency backend systems in Go
Modern React frontend with state management (Redux or Context API)
Working with both relational (PostgreSQL) and NoSQL (MongoDB) databases
Cloud-native deployment on AWS, containerised with Docker
Designing and integrating secure RESTful and/or GraphQL APIs
End-to-end development in a polyglot environment with a focus on scalability

Our expectations of the candidate:

Experience: 6+ years of professional software engineering experience, with at least 3 years in full-stack development
Backend Mastery: Strong proficiency in Go for building high-concurrency systems
Frontend Expertise: Advanced skills in React and JavaScript, including state management (Redux or Context API)
Database Proficiency: Proven experience with PostgreSQL (schema design, query optimization) and MongoDB
Infrastructure: Hands-on experience with containerization (Docker) and cloud platforms such as AWS
Tools: Familiarity with modern development workflows including Git, CI/CD pipelines, and AI-assisted tools (e.g., GitHub Copilot)
English: Upper-Intermediate

Soft skills:

Strong ownership mindset and accountability
Ability to balance backend depth with frontend usability
Effective communication in cross-functional teams
Analytical thinking and structured problem-solving
attitude and continuous learning mindset
Ability to prioritize and work in a fast-paced environment

Responsibilities and tasks:

System Design: Architect and develop robust, scalable microservices and APIs using Go and JavaScript.
Frontend Excellence: Lead the development of responsive and performant user interfaces using React and modern JavaScript (ES6+).
Database Management: Design, optimize, and manage data models across both relational (PostgreSQL) and NoSQL (MongoDB) databases.
API Development: Build and integrate secure RESTful and/or GraphQL APIs to ensure seamless communication between client and server.
Code Quality: Conduct rigorous code reviews, provide constructive feedback, and advocate for engineering best practices like CI/CD and automated testing.
Reliability: Monitor application health, troubleshoot production issues, and optimize for maximum speed and scalability.

We offer:

Work on a product for a TOP-5 global management consulting firm — the kind of line that carries weight on your CV for the rest of your career
Our own office in Noida — not a co-working desk: a growing, greener, less congested and more affordable location than Gurugram or Delhi NCR
Direct, transparent employment with a local legal entity (INSTINCTOOLS INDIA PRIVATE LIMITED): correct payroll, correct tax withholding, full compliance — no intermediaries between you and the company.
A real team, not a staffing bench: we do regular team events, you get a buddy to help you onboard, you can talk to your delivery manager directly, and you’ll have ongoing support from both the project and the company — with a local manager right here in India.
Structured feedback: a regular 1:1 cadence with your delivery manager and collected feedback from the client’s tech leads
Learning and development are part of how we work: the company supports your growth and creates opportunities to explore new technologies.

Join us and be part of a team that is changing the world through technology.
