Technical Lead- Architecture & Engineering

🚀 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
• Strong 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.
