Tech Lead - Full Stack (MERN)

Job description

🚀 Founding Product Engineer

Preferred Location: Chennai. 50% In Office, 50% Remote.

Very important:You must be able to work from the office (Chennai / Bangalore) multiple times a week.

Type: Full-time.

Compensation: Competitive with meaningful equity/token upside

🧬 Who We Are

We’re building two interconnected products:

• Airavat – a next-gen, AI-powered crypto exchange.
• Tatv.ai – an automated, retail-facing algorithmic trading platform.

Our mission: to democratize access to crypto and powerful trading tools, whether you're a long-term investor or a high-frequency scalper. We're combining real trading infrastructure with cutting-edge AI to give every user an edge.

🎯 The Opportunity

Join us as a founding product engineer — not just a developer, but a builder who thinks in terms of product, UX, and outcomes. You’ll work across systems and interfaces, but you’ll also influence what gets built, why, and how fast it ships.

This isn’t a job for someone who only wants Jira tickets. It’s a role for someone who:

• Wants to help define the product, not just implement it.
• Has a sixth sense for what’s “good enough to ship” vs “must be rock solid.”
• Wants the challenge of owning a live trading system that real people use and trust.

🧰 What You Bring (Required Skills)

• 4+ years in hands-on, full-time software engineering roles.
• Strong full-stack skills, especially across the MERN stack.
• Proven experience designing and building backend APIs, scalable services, and polished UIs.
• Real-world experience with Blockchain/Crypto systems — ideally working with node APIs, smart contracts, or exchange flows.
• Solid grasp of systems architecture: You can model tradeoffs, cache intelligently, and reason about data consistency, failure states, and latency.
• You ship with craftsmanship and care: logging, tests, devops awareness, and proper config are part of your definition of done.
• You're already AI-augmented: You fluently use tools like GPT, Claude, Cursor, Agents, or Replit to accelerate coding, testing, and problem-solving.

🌟 Bonus Points (Nice-to-Haves)

• Experience with NestJS or structured back-end frameworks.
• Built or managed Telegram bots using frameworks like GrammyJS.
• Have shipped at least one consumer-facing product to a large or real audience.
• Can point to apps, bots, tools, or open-source work you’ve led or contributed to.
• Familiarity with AI agent frameworks or building your own task orchestration logic.
• Prior experience managing / mentoring junior engineers.

🧠 Mindset We’re Looking For

You might be a great fit if you:

• Are a product-minded engineer: You think deeply about what users want, and you often suggest product improvements before anyone asks.
• Take a long-term view: You’re looking to grow with a team and vision — not bounce from gig to gig.
• Have a bias for ownership: You don't need tight specs. You’re capable of scoping, architecting, and executing features independently.
• Are multipurpose: Infra, bots, prompt flows, smart contract interaction — you’re ready to wear multiple hats.
• Move with urgency: You want to outpace the market, not just keep up.
• Care about purpose and outcomes, not just completing tasks.
• Are genuinely interested in Crypto, DeFi, trading, or AI systems — or better, all of them.
• Use AI not as a gimmick, but as an integral part of your day-to-day engineering process.
• Understand what it means to balance shipping with quality: not gold-plating, not cutting corners — just doing things smart and fast.

💰 What You Get

• Founding engineer status with direct impact on both product and company.
• The opportunity to grow with the organization. No role is off limits.
• Competitive market salary.
• Early equity/token upside with long-term comp potential.
• A career-defining opportunity to build something from scratch — without red tape.
• Autonomy and influence across product, technical architecture, and user experience.
• A highly aligned founder and mission-first environment, where speed and craftsmanship are equally respected.
