Location: Gurgaon - India

Salary: Competitive

Hours: UK Shift

About the role

We’re building a new AI & Automation function — a small, high‑trust, high‑autonomy team operating inside an established business. We move fast, build real things, and ship value in days, not weeks. Internal tools that prove their worth get packaged and sold as commercial products. Everything you build has a second life.

We’re hiring two founding generalist engineers to help define how this team works and what it becomes.

You’ll thrive here if you like:

• Fast cycles, short feedback loops, and real ownership

• Picking up a brief, asking smart questions, and shipping something working in days

• Prototyping over perfection

• Autonomy without bureaucracy

• Owning your work end‑to‑end — from idea to live system

No ticket queues. No six‑week design cycles. You own what you build from brief through to live, and you're accountable for whether it actually solves the problem.

Tech Stack - Python · JavaScript/Node.js · React/Next.js · GCP · Vertex AI Claude API · Gemini · LangChain · n8n · Cloud Run BigQuery · PostgreSQL · REST APIs · Docker · Git

What you'll build

• Agentic AI workflows using Claude, Gemini, LangChain/LangGraph

• Internal tools for Sales, CX, and Operations - dashboards, AI-assisted workflows, and process automation that make Onecom faster

• User‑facing AI products that can be commercialised

• GCP‑native backend services (Cloud Run, Functions, Pub/Sub, BigQuery, Vertex AI)

• Frontend interfaces in React or Next.js

• Integrations across CRMs, ticketing systems, data warehouses, and communication tools

• Custom enterprise solutions bespoke solutions for clients where standard products don’t fit

What makes you a great fit

You don’t need to be an expert in everything, but you should be competent across most of the stack and able to learn fast. You’ve built things end‑to‑end before. You can point to something live, explain your decisions, and be honest about what you’d improve. You think about failure modes, not just happy paths. Most importantly: you get things done.

Core Technical Skills

• Python and/or JavaScript — you can write clean, production‑quality code

• GCP experience – hands on with CGP services (cloud run, Functions, BigQuery, Vertex AI, Firebase)

• SQL - comfortable writing and optimising queries against PostgreSQL, MySQL, or BigQuery as part of automation flows

• n8n — strong experience; our primary automation platform for orchestrating complex business logic across systems

• AI & LLM integration - you’ve shipped something real using Claude, Gemini, GPT, or equivalent

• Frontend development - React or Next.js for UI development

• API design & integration - REST, OAuth2, webhooks, event‑driven systems

AI Specific Skills

• Prompt engineering — you can write and iterate production-quality prompts; familiar with chain-of-thought, few-shot examples, structured JSON output, and system/role prompt design

• AI output validation — you know how to build validation and fallback layers around LLM outputs before they hit downstream systems; you don't just call the API and trust the result

• AI security & governance — awareness of prompt injection risks, PII handling in AI pipelines, and output sanitisation; you think about what happens when things go wrong

• LLM API trade-offs — practical understanding of token limits, temperature, model selection, and when to use which model for wha
