About the Role

SwitchKart is on a mission to make technology more accessible and more sustainable — we're in the business of recommerce, giving old smartphones a second life, cutting down e-waste, and extending the lifecycle of every device we touch.

We're looking for a Senior Full Stack Developer to help us build and scale the ecosystem of platforms powering this mission — from our procurement app to our retailer app, pricing engines, and warranty systems. You'll take ownership of complex features end-to-end, mentor junior engineers, and make architectural decisions that shape how we grow.

What You'll Do

• Own Features End-to-End: Design, build, and ship full stack features across our procurement, retailer, pricing, and warranty platforms — from database schema to UI polish.

• Drive Architecture: Make key technical decisions on system design, scalability, and code structure as our ecosystem of apps grows.

• Build AI-First: Design and build systems with AI at the core — not bolted on. Think about where AI can automate, assist, or enhance the products you're building from day one.

• Build Scalable Architecture: Build and monitor a highly performant, failure-resistant platform — we take pride in doing this with a small, high-ownership team.

• Automate and Integrate: Develop tools that automate our integration processes and build data pipelines across our app ecosystem.

• Foster Technical Excellence: Champion unit and integration testing and lead meaningful code reviews across the team.

• Prototype and Validate: Create interactive prototypes to prove out technical concepts and participate in pilots for new initiatives.

• Mentor the Team: Guide junior developers through code reviews, pairing, and technical direction.

• Report Upward: Provide regular updates to management on milestones, risks, issues, and mitigation plans.

• Collaborate Cross-Functionally: Work closely with product and design to translate requirements into robust technical solutions across multiple products.

What We're Looking For

Must Have

• 4+ years of full stack development experience

• Strong proficiency in React and Node.js

• Solid experience with PostgreSQL or MySQL — schema design, query optimisation

• Experience designing and scaling production systems

• Experience deploying and managing applications on a cloud platform (AWS/GCP or similar)

• Comfortable owning a feature from concept to deployment

• Strong debugging and problem-solving skills

Good to Have

• Experience mentoring or leading junior engineers

• Track record of driving scalability and time-to-market in past cloud architecture decisions

• Exposure to CI/CD pipelines

Title: Hands‑on Tech Lead (AI Agents, Automations, Chatbots)

Type: Full‑time (preferred) or full‑time‑equivalent contractor

Location: Remote (India-friendly), must overlap with founder for live collaboration

Comp: Flexible; you indicated up to ~$50k/year is comfortable for the right person

Why this role exists

We build and deploy rough-but-working “minimum viable applications” fast (days/weeks, not months) for small businesses, then gradually extract reusable components so the best solutions become repeatable products.

You’ll be the engineering owner who can design + ship, keep quality “clean enough,” and avoid the long-term trap of one-off scripts.

What you’ll build

• AI-agent driven automations using n8n (including agentic workflows, tool usage, memory/DB access, and production hardening). n8n explicitly positions AI Agents as autonomous workflows that make decisions and execute tasks, and provides dedicated AI agent capability pages/docs.  
• Conversational chatbots (web + messaging + optionally voice) with reliable orchestration, state, and analytics
• Voice experiences using ElevenLabs Text‑to‑Speech (and optionally Speech‑to‑Text), including real-time or low-latency flows.  
• Admin/internal tooling (e.g., Retool) to manage clients, prompts, workflows, logs, and operations. Retool’s own positioning: connect to databases/APIs/LLMs and build internal tools.  
• (If applicable) Voice agent platforms such as Retell AI (inbound/outbound voice agent platform + docs).  

Responsibilities

Shipping (hands-on)

• Build the first end‑to‑end “vertical slices” yourself (agent/workflow → backend/service → DB → UI/admin → deployment).
• Deliver working MVAs rapidly; optimize for time-to-deploy while maintaining baseline reliability.

Architecture & productization

• Define a lightweight but real architecture that supports:
• multi-client deployments (config/tenant separation)
• prompt/version management
• logging + observability
• secure secret handling
• repeatable integrations and “workflow templates”
• 
  
• Establish “golden path” patterns so new projects are mostly configuration + reuse.

Leadership

• Lead (and unblock) an Implementation Engineer: tickets, code review, standards, and technical direction.
• Produce short docs and checklists so others can build consistently.

Required experience (must-haves)

• Strong full‑stack fundamentals (API design, auth, data modeling, debugging, deployments).
• Proven experience building automation/workflow systems (preferably n8n in production).
• Experience with LLM + agent patterns: tool calling, retrieval/RAG, structured outputs, prompt/versioning, evaluation, failure handling.
• Conversational chatbot experience (web or messaging). Voice is a plus.
• Ability to design databases and data flows (Postgres/MySQL/etc.), including migrations and indexing.
• Strong written communication: can turn ambiguous needs into a plan, and can document the “how to run it.”

Strong plus

• Retool (or similar low-code internal tooling) experience.  
• ElevenLabs voice integration (TTS/STT) in production.  
• Experience with Retell AI or similar voice-agent platforms (Vapi/Retell/etc.).  
• Experience self-hosting and operating systems: Docker, CI/CD, monitoring, secrets.

• BTech, BE, BS degree in Computer Science, a similar technical field of study, or equivalent practical experience.
• 6+ years experience in web and software development.

• 3+ years of experience with the microservices architecture.
• At least 1 year of experience in leading a team.
• Demonstrated experience in Node, Mongo, Python2/3, Express, ReactJS.
• Experience with testing frameworks like Mocha, Jest, Jasmine etc.
• Experience with asynchronous messaging using RabbitMQ/Apache Kafka.
• Ability to work independently and multi-task effectively.
• Flexible and willing to accept a change in priorities as necessary.
• Strong attention to detail.

Design and build applications, bug fixing and improving application performance.

• Delegate tasks and achieve daily, weekly, and monthly goals.
• Enforce processes to improve productivity of the team.
• Collaborate with cross-functional teams to define, design, and ship new features.
• Work on continuously discovering, evaluating, and implementing new technologies to maximize

development efficiency.
