? Technical Lead – Architecture & EngineeringBuild technology that helps solve India’s water crisis ?? Chandigarh Tricity | Full-time | On-site

?‍? 7–10 years experience

At Wattr.ai, we are building technology for one of India’s most important challenges — water.

We are building the digital intelligence layer for real-world water infrastructure, bringing together IoT, sensors, cloud, data and AI to help monitor and manage water infrastructure at scale.

We are looking for a hands-on Technical Lead who will take ownership of the technology from business requirement to production.

Business Requirement → Product Requirement → Architecture → Engineering Plan → Sprints → Development → Deployment → Production → Scale

? You will architect the system.

? You will build critical parts of it.

? You will lead the engineering team executing it.

? You will own technical delivery against product goals, KPIs and deadlines.

? What you will ownYou will be the technical bridge between Product and Engineering.

You will

→ Understand business and product requirements and translate them into technical solutions and system architecture

→ Design the architecture across application, APIs, databases, data pipelines, cloud infrastructure, integrations and real-time systems

→ Break product requirements and architecture into engineering modules, technical tasks and sprint deliverables

→ Plan sprints, sequence dependencies and assign work across engineers

→ Track engineering execution, resolve technical blockers and ensure delivery against product milestones and business KPIs

→ Remain hands-on with development, particularly on complex or critical components

→ Review code and technical implementation and maintain engineering quality

→ Identify scalability, reliability, security and performance issues and drive them to resolution

→ Take products from 0→1 through production and scale

? Technology ownershipYou should be comfortable working across the complete technology stack:

Frontend → Backend → APIs → Data → Real-time → IoT → Cloud → Infrastructure → AI

Full-stack EngineeringStrong hands-on experience with:

- Node.js and backend development
- React and modern frontend development
- REST APIs and service integrations
- Databases and data modelling
- Authentication, authorization and application security
- Performance optimisation and production debugging

☁️ AWS, Cloud & InfrastructureStrong production experience with AWS and cloud-native systems.

Relevant experience includes

- EC2, S3, RDS / time-series databases and other AWS services
- AWS IoT Core or equivalent IoT platforms
- Docker and containerised applications
- Kubernetes / EKS
- Infrastructure as Code such as Terraform
- CI/CD and automated deployments
- Cloud networking and security
- Monitoring, logging and observability

We are looking for someone who can build and evolve infrastructure, not simply consume infrastructure created by others.

? IoT, Real-time & DataWattr operates at the intersection of software and physical infrastructure.

Experience with

- IoT / connected devices




- MQTT / pub-sub architectures
- Sensor telemetry and real-time data ingestion
- Event-driven systems
- Kafka or similar streaming technologies
- ETL / data ingestion pipelines
- Time-series data
- High-volume event processing
- Real-time alerts, reporting and monitoring
- Edge-to-cloud architectures

Experience handling thousands of events per minute or comparable production scale is highly valuable.

? AI & AI-assisted EngineeringExperience with:

- LLMs / GenAI
- RAG or agentic systems
- AI/ML APIs and integrations
- AI/ML pipelines
- AI-assisted development using tools such as GitHub Copilot, ChatGPT, Claude or equivalent

We value engineers who use AI practically to improve engineering velocity, quality and problem-solving.

? Architecture & System DesignArchitecture ownership is mandatory.

You should have at least 2–3 years of hands-on experience owning production architecture and system-design decisions, including:

- Translating business requirements into technical architecture
- Defining service, API, data and integration boundaries
- Making technology and architecture decisions
- Designing for scalability, reliability and performance
- Cloud and infrastructure architecture
- Security and observability
- Evolving architecture as products grow

We are looking for someone who has built what they architected — not a pure enterprise architect or documentation/consulting profile.

? Technical LeadershipYou will lead the engineering team from a technical execution perspective.

This means

→ Converting product requirements into clear engineering plans

→ Breaking large requirements into executable tasks

→ Planning and driving sprints

→ Assigning work based on priorities, complexity and engineer strengths

→ Tracking delivery and resolving dependencies/blockers

→ Reviewing code and architecture

→ Mentoring engineers and raising engineering standards

You should be comfortable leading a small engineering team while remaining a strong hands-on developer.

? 0→1 Product BuildingYou should have taken at least one product, platform or major system through:

Idea → Architecture → First Build → MVP → Production → Scale

Startup experience and experience working in high-ownership environments are strong advantages.

? Why this role is excitingYou won't own just one part of a software stack.

You will have visibility into the complete product and technology lifecycle.

You will understand the business problem → work with Product → design the architecture → plan the engineering execution → lead the sprints → build critical technology yourself → deploy it → see it operate in the real world.

And the real-world application is meaningful:

? Water infrastructure

? Connected devices & sensors





? Live operational data

? AI-driven intelligence

?️ Large-scale infrastructure

?? Real impact across India

This is technology that doesn't just live on a screen.

It interacts with the physical world.

? What success looks likeWithin your first 6–12 months, you should be able to:

→ Own the technical architecture of key Wattr products

→ Establish a strong product-to-engineering execution process

→ Ship a field-tested MVP rapidly

→ Build reliable systems around live sensor/device data

→ Establish scalable backend, frontend and data systems

→ Build robust alerts, reporting and intelligence capabilities

→ Strengthen automated testing, CI/CD, monitoring and observability

→ Ensure engineering execution consistently meets product milestones and business KPIs

→ Help make technology a genuine competitive advantage for Wattr.ai

✅ What we're looking for• 7–10 years of software engineering experience

- 2–3+ years of hands-on architecture / system-design ownership
- Strong hands-on full-stack development
- Strong Node.js + React experience
- Strong AWS/cloud and infrastructure experience
- Experience building infrastructure and deployment systems from scratch
- Strong understanding of APIs, databases and distributed systems
- Experience with data pipelines, streaming or high-volume real-time systems
- Experience taking products/systems from 0→1
- Experience leading engineering execution and mentoring developers
- Strong sprint planning, task breakdown and delivery ownership
- IoT / MQTT / telemetry / real-time systems experience is a strong advantage
- AI / GenAI and AI-assisted development experience is a strong advantage
- Robust ownership, problem-solving and communication skills

? The profile we are NOT looking for❌ Pure people manager

❌ Pure enterprise / consulting architect

❌ Backend-only or frontend-only engineer

❌ Architect who is no longer hands-on

❌ Developer who has only implemented within an architecture defined by others

We are looking for someone who can:

Understand → Architect → Break Down → Assign → Build → Review → Ship → Scale

? Why Chandigarh?Wattr.ai is currently building from Chandigarh Tricity, and this role is on-site.

For a technical leadership role involving close interaction between Product, Engineering and Operations, we believe working together enables faster decisions and stronger execution.

Chandigarh also offers a compelling quality-of-life advantage — cleaner air, lower living costs, shorter commutes and a calmer environment for focused work.

Relocation support may be available for the right candidate.

? CompensationCompetitive compensation based on experience and fit, with meaningful long-term growth as Wattr.ai scales.

This role can grow into broader engineering leadership and ownership as the company and technology platform expand.

? Ready to build something that matters?If you are the kind of engineer who looks at a complex problem and thinks:

“Let me understand the whole system — and then let me build it.”

We would love to hear from you.
