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!
