🚀 Hiring: Software Development Engineer (L2/L3) | Backend | Noida Posted by Unicon HR — 20+ Years of Trusted Recruitment Partnerships

About the Company

Our client is building the next layer of digital infrastructure — a globally ambitious, Web3-native platform that puts users, builders, and creators first. They've built their own L1 blockchain and are solving some of the hardest problems in digital infrastructure: protecting user rights, intellectual property, and digital assets in an AI-first world.

This isn't maintenance work. This is foundational engineering on systems that could serve billions.

The Role

Software Development Engineer — L2/L3 | Noida (Hybrid) | 5–8 Years Experience

We're looking for engineers who live and breathe DSA and system design — people who find a hard LeetCode problem genuinely exciting, and who take pride in building backend systems that are fast, clean, and built to last.

You'll own real components, influence architecture, and work on distributed systems powering a live blockchain network.

What You'll Do

• Design and develop scalable, high-performance backend systems
• Solve complex problems using optimal data structures and algorithms
• Own components end-to-end — from architecture through production
• Drive technical design discussions and contribute to code reviews
• Optimize the distributed architecture of the Kwala network
• Collaborate across teams working on blockchain, protocols, and ecosystem tools

What We're Looking For

• 5–8 years of backend development experience
• Strong CS fundamentals — DSA (LeetCode Medium/Hard), system design, concurrency
• Language-agnostic coding ability; experience with Java, Golang, or similar
• Deep understanding of OOP and functional programming paradigms
• Experience with distributed systems and scalable architectures
• Familiarity with cloud services and modern backend frameworks
• Bachelor's/Master's in Computer Science or equivalent

Hiring Process

3–4 rounds | Technical + System Design + HR + Leadership

Why This Role?

✅ Work on a real L1 blockchain and distributed infrastructure

✅ High-ownership culture with freedom to operate across products
