Senior Xano Developer
Visual Backend Development, APIs & AI-Assisted Build
📍 Mumbai (On-site) | Full-time | 3-5 years
About the Role:
Unico Connect is an AI-first technology partner that builds custom mobile, web, and AI products for clients across multiple geographies.
We are hiring a Xano Developer who will build backend systems and APIs for our customer engagements on Xano, the visual backend development platform.
The mandatory requirement for this role is hands-on production backend engineering experience, including PostgreSQL data modelling and REST API design, in either a Node.js or Python environment.
Prior production work on Xano is strongly preferred.
The role is hands-on and customer-facing. You will own backend delivery across engagements: designing data models, building API flows in Xano, integrating third-party services, and partnering with frontend, mobile, and AI engineers on contracts and behaviour.
The work spans all three Xano build modes: no-code function stacks, custom code through Xano’s scripting and code blocks, and Xano’s AI assistance and agentic features.
A typical week includes a data model review for a new engagement, building a complex API flow in Xano, integrating a third-party webhook, and a customer working session on a new module.
Responsibilities:
Backend Delivery on Xano
Own end-to-end backend implementation on Xano: database schema, API endpoints, function stacks, background tasks, and integrations.
Ship production-ready work that meets customer requirements and engineering quality standards.
Build Across All Three Xano Modes
Use Xano’s no-code function stacks for standard CRUD and business logic.
Drop into custom code (JavaScript, Python through code blocks, expressions) where visual flows would be unwieldy.
Use Xano’s AI assistance and agentic features to accelerate routine build work.
Database Design on PostgreSQL
Own data model decisions for each engagement: table design, relationships, indexes, addons, and query performance.
Make schema choices that hold up as product usage grows and that map cleanly to the API contracts the client needs.
API Design and Integration
Design clean REST API contracts that the frontend, mobile, and third-party consumers can rely on.
Cover authentication, input validation, pagination, error handling, and rate limiting.
Integrate external services (payment gateways, messaging, storage, AI providers) through Xano’s connectors and custom requests.
Product Thinking and Solutioning
Translate fuzzy product asks from customers into concrete backend solutions.
Ask the right questions about edge cases, data lifecycle, multi-tenancy, and access control before building.
Push back on requirements that will cause pain later.
Customer Communication
Work directly with customers in discovery, design reviews, demos, and weekly working sessions.
Explain trade-offs in plain language, present options with clear recommendations, and write tight technical updates.
AI-Assisted Backend Development
Use Xano’s built-in AI features as well as external AI tools (Claude, Cursor, and similar) day to day for schema drafts, function stack scaffolding, query writing, integration setup, and review.
Develop strong instincts for when AI output is usable as-is and when it must be reworked.
Quality, Testing, and Reliability
Test the flows you ship.
Set up sensible error handling, logging, and alerts for the backend services you own.
Participate in incident response when something breaks in production.
Documentation and Handover
Document data models, API contracts, and non-obvious decisions inside Xano and in shared docs so the rest of the team and the customer can pick up the work without you in the room.
Continuous Learning
Track changes to the Xano platform, including new features, performance improvements, and AI capabilities.
Apply them to active engagements where they reduce build effort or improve product outcomes.
Requirements:
Hands-on Production Backend Engineering Experience (Mandatory)
Must have personally shipped backend systems to production for real users, with ownership of API design and data modelling.
POCs, coursework, and internal-only tools do not qualify.
3 to 5 Years of Professional Backend Engineering Experience
In either a Node.js or Python environment.
Candidates with slightly less time but strong demonstrated ownership are welcome to apply.
Strong PostgreSQL Skills
Schema design, indexing, query writing, and migrations on at least one production system.
Able to reason about query performance and design data models that hold up under realistic product usage.
REST API Design and Integration Depth
Comfort designing API contracts that are clean, predictable, and easy for frontend, mobile, and third-party consumers to work with.
Experience integrating external services such as payment gateways, messaging providers, storage, and AI APIs.
Familiarity with at Least One Node.js or Python Backend Stack
Such as Express, NestJS, Fastify, FastAPI, Django, or Flask.
Comfort reading and writing application code outside of visual environments when the situation calls for it.
Product Thinking and Solutioning
Ability to take a fuzzy product brief, ask the right questions, and propose a backend design that is fit for purpose.
Strong instincts for what to build first, what to defer, and what not to build.
Strong Written and Spoken English Communication
Confident in customer working sessions and design reviews.
Comfortable writing precise technical documentation and explaining trade-offs to non-engineering stakeholders.
Cloud and Deployment Fundamentals
Working knowledge of at least one of AWS, GCP, or Azure: deploying services, reading logs, managing environments, and basic operational tasks.
Familiarity with Docker is a plus.
Bachelor’s Degree
Bachelor’s degree in Computer Science, Information Technology, or a related engineering discipline.
Exceptional candidates with demonstrable production experience and strong portfolios may be considered without a formal degree.
Nice to Have
- Prior production experience on Xano, Bubble, Retool, or comparable visual or low-code backend platforms
- Full stack experience with React, Next.js, React Native, or Flutter
- Experience integrating LLM APIs (OpenAI, Anthropic, Google) into backend workflows
