Compiler Engineer, Programming Language Developer.

About IndianBrand Technology

IndianBrand Technology is a Hyderabad-based technology company building India's complete digital sovereignty stack INDDN (India's own search engine at inddn.in), IndianBrand Browser, IndianBrand OS, and now INK — India's first programming language.

INK is a systems programming language with the speed of C, the simplicity of Python, and the safety of Rust. Every INK file ends in .in — India in every file, in every computer, in every country in the world. This is genuinely historic work — no Indian has ever built a programming language before.

JOB TITLE: Language Engineer — INK

Location : 100% Work From Home — anywhere in India

Employment Type : Part Time / Freelance / Full Time — your choice

Working Hours : Fully flexible — async communication

Experience : 5 to 8 years

Salary : 50,000 – 1,00,000/month based on experience

Joining : Immediate

SPECIAL NOTE

This role is open to everyone — including homemakers, women returning to tech after a career break, researchers, and academics. If you have built a compiler, interpreter, or programming language — in any form, at any scale — we want to talk to you. Career gaps are never a barrier here.

WHAT IS INK

INK is India's first programming language. It is designed to:

• Write the IndianBrand OS kernel — like C
• Write web servers and AI models — like Python
• Be safe by design — no null crashes, no buffer overflows
• Compile to native machine code via LLVM — ARM64 + x86-64
• Use .in as the file extension — India in every file worldwide

ABOUT THE ROLE

You will be the founding engineer of the INK programming language. You will design and build the compiler from the ground up — lexer, parser, type system, semantic analyser, LLVM code generation, standard library, and build tools. This is a rare opportunity that very few engineers in India — or the world — have ever had.

You will work directly with the founder. Your decisions will shape the language that millions of Indian developers will use for decades.

WHAT YOU WILL BUILD

Phase 1 (Months 1–3)

• Lexer — tokenises INK source code character by character
• Parser — builds Abstract Syntax Tree from tokens
• Basic evaluator — variables, functions, if/else, loops
• Hello World: ink run hello.in prints Jai Hind!

Phase 2 (Months 3–6)

• Type system — int, float, text, bool, list, map
• Type inference — let x = 5 without writing int
• Custom types — type Person { name: text, age: int }
• Error handling — or keyword, Result types, Optional ?
• Collections — list, map, set with built-in operations

Phase 3 (Months 6–9)

• LLVM backend — compiles INK to native x86-64 machine code
• ARM64 target — compiles for smartphone chips
• Basic standard library — io, file, text, math modules
• ink build produces a real executable binary

Phase 4 (Months 9–12)

• System mode — @system annotation for OS/kernel development
• Raw pointer support — ptr[u8](0xB8000) for VGA buffer
• Manual memory control in system mode
• Write IndianBrand OS kernel in INK — milestone!

Phase 5 (Year 2)

• Web standard library — web.route, web.listen, json
• Database library — db.find, db.save, db.all
• Self-hosting — INK compiler written in INK itself
• inkpkg — INK package manager
• VS Code extension — syntax highlighting and autocomplete

MUST HAVE SKILLS — TECHNICAL

Compiler Theory (Essential)

Lexical analysis — tokenisation, regular expressions, finite automata

Parsing — recursive descent parser, LL(1) grammars, Abstract Syntax Tree

Semantic analysis — type checking, scope analysis, symbol tables

Intermediate representation — IR design, SSA form

Code generation — translating AST/IR to target instructions

Programming Languages (Essential)

C — expert level — the entire INK compiler is written in C first

C++ — strong — needed for LLVM integration

Assembly — x86-64 or ARM64 — understanding of generated code

At least one of: Rust, Go, Haskell, OCaml — functional/systems thinking

Tools & Infrastructure (Essential)

LLVM — understanding of LLVM IR and the LLVM toolchain

GCC/Clang — experience building and working with compilers

GDB — debugging compiled code at assembly level

Git — version control, branching, pull requests

Linux — comfortable on Ubuntu or similar

CMake or Make — build systems

Language Design (Strong Plus)

Type system design — static typing, inference, generics

Memory model design — ownership, lifetimes, automatic management

Standard library design — API design, module systems

Error handling design — Result types, exceptions, propagation

Syntax design — grammar definition, readability principles

NICE TO HAVE SKILLS

Prior programming language implementation — any language, any scale

Rust — memory safety concepts directly applicable to INK

ANTLR or Yacc/Bison — parser generators

OCaml or Haskell — functional languages used by compiler researchers

Language Server Protocol (LSP) — for VS Code extension

WebAssembly (WASM) — future INK compilation target

Operating system internals — INK is used to write IndianBrand OS

Academic background in computer science — PL theory, type theory

Prior open source contributions to compilers (GCC, LLVM, Rust)

MUST HAVE — PERSONAL QUALITIES

Curiosity — you read programming language papers for fun

Patience — building a language takes years, not weeks

Ownership — you treat INK like your own language

Communication — you explain complex things simply

Self-motivated — you work without being told what to do next

Honest — if something will take longer, you say so early

Passion — you genuinely care about building something historic for India

WHAT WE OFFER

80,000 – 3,00,000/month based on experience and commitment

Claude AI Fable-5 Pro subscription — 1,700/month value — provided

100% Work From Home — no commute ever

Fully flexible hours — async communication only

Part time or full time — your choice

Your name in INK language credits — permanent and historic

Direct collaboration with the founder

Equity discussion possible for exceptional candidates

Be the founding engineer of India's first programming language

Career gap is never a barrier — skill is everything

HOW TO APPLY

[email removed]

Subject: Language Engineer — INK — [Your Name]

Please include:

1. GitHub link or any compiler/interpreter you have built — even a toy language counts

2. Answer these 3 questions:

a) What is the difference between a lexer and a parser?

b) What is an Abstract Syntax Tree? Draw one for: let x = 5 + 3

c) What is LLVM and why do programming languages use it?

3. Your preferred commitment — part time hours per day OR full time

4. Any career break details — we understand and welcome returning engineers

Note: Candidates without any compiler, interpreter, or language implementation experience will not be considered — even if they have 10 years of general software development. This role requires very specific skills.
