About the Role

We are building IndianBrand Mobile OS — India's first 100% from-scratch operating system. We need a Kernel Engineer who can write bare-metal C code and understand how operating systems work at the lowest level. This is rare, exciting, and genuinely historic work.

Required Skills

• C Programming (expert level) — you must be comfortable writing C without any standard library
• x86 or ARM Assembly — basic understanding of Assembly language
• Operating system fundamentals — memory management, process scheduling, interrupts
• Linux development environment — comfortable on Ubuntu or similar
• GDB — debugging compiled code
• Git — version control

Key Responsibilities

• Write and improve kernel code in C — memory manager, interrupt handlers, process scheduler
• Write Assembly code for low-level hardware initialisation
• Test kernel changes in QEMU virtual machine
• Document code clearly for the team
• Collaborate asynchronously with other developers via Git and email
• Research and implement OS concepts from OSDev Wiki and reference documents

Phase 1 is already complete — bootloader, kernel, VGA driver, keyboard driver, and basic shell all working in QEMU. You will work on Phase 2 (memory manager, interrupts) and beyond.

Nice to Have

• Rust — for memory-safe kernel components
• ARM64 experience — for Phase 4 phone hardware port
• Prior OSDev or embedded systems experience
• Familiarity with QEMU, Bochs, or other emulators
• Understanding of device drivers
• Computer Science degree or equivalent self-taught background

What We Offer

15,000 – 40,000/month based on hours and experience

Claude AI Pro subscription — worth 1,700/month

100% Work From Home — no commute ever

Fully flexible hours — work during school hours, after bedtime, whenever suits you

No fixed office hours — async communication only

Part time — 2 to 4 hours/day is enough

Be part of India's most ambitious OS project

Your name in the IndianBrand OS credits — historic contribution

Direct collaboration with the founder
