Senior Full-stack Developer (Python+React)

• instinctools is a software development company that provides custom software solutions for businesses of all sizes. Our team works closely with clients to understand their specific needs and provide personalized solutions that meet their business requirements.
• instinctools is looking for a Senior Full-stack Developer (Python+React) for one of our clients.

Location: Noida, India

Work mode: Office/Hybrid (4 days in the office, 1 day remote)

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.

Project: our project is a premier, cloud-based big data analytics platform that serves as the technology backbone of the Company’s commercial operations. It combines proprietary IP, prescriptive analytics engines, role-specific digital workbenches, and real-time decisioning capabilities to help enterprise clients drive pricing precision, commercial excellence, and sustainable revenue growth.

The platform processes large volumes of transactional and market data to power pricing, deal-scoring, and promotional-optimization engines, exposes this intelligence through purpose-built web workbenches, and integrates natively with clients’ ERP, CRM, and CPQ ecosystems.

The team is actively embedding Generative AI and agentic capabilities — automated data structuring, natural-language insight generation, and AI-assisted decision workflows — into the core product, alongside building modular, rapidly-deployable configurations for mid-market clients.

What You Will Get Hands-on With

• Cloud-native deployment on AWS, containerised with Docker and Kubernetes
• Large-scale data pipelines: Spark, Airflow, Kafka
• Production GenAI and agentic workflows — LLM-powered data structuring, natural-language insight generation, AI-assisted decisioning — shipped to enterprise users, not prototypes
• A genuinely varied task flow: pricing engines, deal-scoring models, ERP/CRM/CPQ integrations, analytics workbenches — no monotonous ticket queue

Responsibilities And Tasks

• Design, build, and maintain full-stack features across a Python-based backend and a React front-end for high-throughput analytics workbenches
• Develop and optimize REST APIs and services that process large, complex commercial/transactional datasets
• Contribute to data model design and query performance for pricing, deal, and promotional-analytics use cases
• Collaborate with data science/ML engineers to integrate predictive and prescriptive models (pricing optimization, deal scoring, product matching) into production workflows
• Help embed GenAI/agentic capabilities (e.g., automated data enrichment, natural-language insight agents) into the product
• Build and support integrations with external CRM, ERP, and CPQ systems
• Participate in architecture discussions, code reviews, and technical decision-making within an Agile team
• Write clean, tested, maintainable code and contribute to CI/CD practices
• Troubleshoot and resolve issues across the full stack in a distributed, cross-functional team

Our Expectations Of The Ideal Candidate

• 6+ years of experience as a Full-Stack Engineer
• 5+ years of recent hands-on experience with Python (Django/Flask/FastAPI or similar)
• 2–3+ years of recent hands-on experience with React (hooks, component architecture, state management)
• Solid experience with PostgreSQL or other relational databases; comfort with data modeling for large-scale/analytical datasets
• Good understanding of REST APIs, microservices, and modern web application architecture
• Hands-on experience building GenAI features into a product: LLM APIs, prompt engineering in production, RAG, or agent frameworks (LangChain/LlamaIndex/similar). We mean product features here — using an AI assistant to write code is a different thing, and we’re happy you do that too.
• Experience working in Agile teams

Nice To Have

• Experience with cloud platforms (AWS/Azure/GCP) and SaaS/hybrid deployment models
• Exposure to data pipelines/ETL, data lake architectures, or big data tooling (Spark, Airflow, Kafka)
• Experience integrating with or building for CRM/ERP/CPQ systems
• Background in pricing, commercial analytics, or B2B/B2C revenue-management domains

English: Upper-Intermediate or higher

Soft Skills

• Strong self-management: ability to work independently and meet deadlines
• Proactive and ownership-driven mindset
• Effective and clear communication, including in distributed teams
• Collaborative, open to feedback, and focused on shared goals
• Strong problem-solving skills, especially in ambiguous contexts typical of evolving enterprise platforms
• High attention to detail and code quality
• Adaptability to shifting priorities and new technologies

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
• Hybrid model: 4 days from our own Noida office + 1 day remote
• 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.
