Java Tech Lead-AVP

We're looking for a high-energy Java engineer to design and implement scalable microservices using Spring Boot. You'll collaborate across teams to deliver clean, efficient, and high-performance backend services.

🛠️ Key Responsibilities

• Design, develop, and maintain RESTful services and microservices using Spring Boot
• Utilize OOP, Java Collections, Exception Handling, and method overloading/overriding in modern coding practices
• Build and optimize multithreaded systems (Threads, synchronization, wait(), notify(), yield()) for performance and scalability
• Write unit and integration tests (JUnit, Mockito, Spring Test) to ensure code quality
• Collaborate with cross-functional teams (QA, DevOps, Product) through code reviews and feature planning
• Diagnose and resolve performance bottlenecksJVM tuning, SQL/caching optimizations
• Adhere to coding standards, best practices, and participate in peer code review

🎯 Required Skills & Experience

• Strong Java fundamentals: OOP, Collections, Generics, Exception Handling
• Concurrency mastery: multithreading, synchronization primitives (wait(), notify(), yield())
• Spring Boot: solid experience building, testing, deploying REST APIs
• Microservices: design, inter-service communication, stateless service patterns
• Testing frameworks: JUnit, Mockito, Spring Test
• Performance tuning: profiling, optimization with JVM settings and database queries
• Tools & practices: Git, Maven/Gradle, CI/CD pipelines, Docker/Kubernetes (plus)
• Soft skills: strong problem-solving, collaboration, and effective communication

About Us:

We are hiring for a pre seed funded startup called Zeromoblt (https://zeromoblt.com/), a high-agency Hyderabad-based startup revolutionizing student transportation with lean, intelligent tech stacks.

Our mission: architect world-class systems from scratch—fast, scalable, and algorithmically sharp—using Kotlin, React, AWS (EC2, IoT, IAM), Google Maps, and multi-cloud setups. Stealth mode operations mean you're building 0→1 products with founders, not fixing tickets.

What You'll Do

• Lead end-to-end ownership of complex systems: design, build, deploy, monitor, and iterate at scale.
• Architect high-performance backends in Kotlin (or JVM langs) that handle real-time routing and IoT data.
• Craft scalable React UIs that power ops dashboards and parent-facing apps.
• Drive cloud decisions across AWS, Azure/GCP—optimising costs for our bootstrap runway.
• Apply DSA/system design to solve hard problems like dynamic route optimization and predictive scaling.
• Shape the engineering roadmap: propose, prioritise, and ship features with founders.
• Mentor juniors while executing solo on high-impact bets—no layers, just results.

We're Looking For

• 3-6 years of hands-on engineering where you've owned and shipped production systems (prove it with code/stories).
• Elite CS fundamentals: advanced DSA, system design (distributed systems a must), design patterns.
• Mastery of Kotlin/Java + modern React; real AWS experience (EC2, IAM, CLI—you know our stack).
• Proven "leap-taker": startup grit, side projects, or open-source that screams hunger.
• Figure-it-out velocity: you thrive in chaos, learn our domain overnight, and deliver 10x faster than peers.

This Role Is Not For You If…

• You need structured roadmaps, PM hand-holding, or big-tech process.
• Comfort > impact: stable salary over equity upside and chaos.
• You've never worn all hats (dev, ops, product) in a resource-constrained environment.

Why Join Us

• Massive ownership: lead tech for 10k+ students, direct founder access, shape ZeroMoblt's scale.
• Flat, high-trust team: flexible Hyderabad/remote, no bureaucracy.
• Hungry culture: we hire hustlers scaling from 700 to 10k students your wins are visible daily.
• Hungry to Leap? Apply now!

Key Responsibilities: 

• Rewrite existing APIs in NodeJS. 
• Remodel the APIs into Micro services-based architecture. 
• Implement a caching layer wherever possible. 
• Optimize the API for high performance and scalability. 
• Write unit tests for API Testing.
• Automate the code testing and deployment process.

Skills Required: 

• At least 2.5 years of experience developing Backends using NodeJS — should be well versed with its asynchronous nature & event loop, and know its quirks and workarounds. 
• Excellent hands-on experience using MySQL or any other SQL Database. 
• Good knowledge of MongoDB or any other NoSQL Database. 
• Good knowledge of Redis, its data types, and their use cases. 
• Experience with graph-based databases like GraphQL and Neo4j. 
• Experience developing and deploying REST APIs. 
• Good knowledge of Unit Testing and available Test Frameworks. 
• Good understanding of advanced JS libraries and frameworks. 
• Experience with Web sockets, Service Workers, and Web Push Notifications. 
• Familiar with NodeJS profiling tools. 
• Proficient understanding of code versioning tools such as Git. 
• Good knowledge of creating and maintaining DevOps infrastructure on cloud platforms. 
• Should be a fast learner and a go-getter — without any fear of trying out new things Preferences. 
• Experience building a large scale social or location-base
