Discover High-Paying Niche Programming Languages: Zig, Erlang, F#, Ruby, and Clojure

According to the 2023 Stack Overflow Developer Survey, demand for several niche programming languages is rising, and companies are willing to pay premium salaries for expertise in them.

Zig

Average salary: $103,611 USD

Zig is a systems programming language designed to help developers build reliable, efficient, and reusable software.

Key goals of Zig:

Works well in all cases, including edge cases.

Executes efficiently by optimizing system‑resource usage.

Reusable across different environments.

Maintains long‑term maintainability; clear code makes troubleshooting easy.

Zig balances high‑level abstractions for productivity with low‑level control for performance.

Demo

hello.zig

const std = @import("std");

pub fn main() !void {
    const stdout = std.io.getStdOut().writer();
    try stdout.print("Hello, {s}!
", .{"world"});
}

Build and run:

$ zig build-exe hello.zig
$ ./hello
Hello, world!

Erlang

Average salary: $99,492 USD

Erlang is ideal for building large, distributed systems that require high scalability, availability, and fast performance. Originally created by Ericsson in the mid‑1980s for telecom software, it is now popular in banking, e‑commerce, and instant‑messaging for its built‑in concurrency, distribution, and fault‑tolerance.

Demo

% hello world program
-module(helloworld).
-export([start/0]).

start() ->
   io:fwrite("Hello, world!
").

Output:

Hello, world!

F#

Average salary: $99,311 USD

F# is a general‑purpose, cross‑platform language focused on functional programming, interoperability, and performance. It encourages concise, robust, and high‑performance code that compiles to efficient .NET IL or JavaScript.

Key features:

Minimal syntax improves readability.

Immutable by default reduces bugs.

Type inference cuts boilerplate.

Pipelining reduces intermediate variables.

Asynchronous workflows simplify scalable async code.

Powerful pattern matching for unions, tuples, arrays, strings, etc.

Supports inheritance, interfaces, and encapsulation.

Demo

dotnet new console -lang F# -o MyApp -f net7.0
cd MyApp
printfn "Hello World"
 dotnet run

Ruby

Average salary: $98,522 USD

Ruby is an open‑source, dynamic language that prioritizes productivity and simplicity. Created by Yukihiro "Matz" Matsumoto, it is widely used for web development, scripting, and general‑purpose programming, offering an elegant syntax and a rich ecosystem of libraries.

Demo

puts "Hello, world!"

Run:

ruby hello.rb
Hello, world!

Clojure

Average salary: $96,381 USD

Clojure blends the ease of scripting with the efficiency of compiled languages, excels at multithreaded programming, and runs on the JVM, providing access to Java libraries. As a Lisp dialect, it emphasizes functional programming with immutable data structures and powerful concurrency primitives.

Demo

(defn sum [numbers]
  (reduce + numbers))
(println (sum [1 2 3 4 5]))

Output:

15
nil

According to the survey, demand for these languages is increasing worldwide, reflected in their high salary levels. While JavaScript and Python remain popular, companies are willing to invest more in developers skilled in niche languages, making them attractive options for career advancement.
