Original job description

Job Title: Full-Stack Developer (Rust & WebAssembly)

Office Location: 7303 Warden Ave. Markham, ON

Employment Type: Full‑time

Application Email: [email protected]

We are looking for a Full-Stack Developer (Rust & WebAssembly) to join our engineering team and contribute to the development of modern, secure, scalable software applications and platforms.

The successful candidate will work across the frontend, backend, APIs, databases, and infrastructure layers, with Rust serving as an important technology across both backend services and selected frontend components through WebAssembly (WASM).

This is an opportunity for a developer who enjoys working across the entire technology stack and is interested in building software where performance, security, reliability, and maintainability are important.

The candidate will work closely with our engineering team to design, develop, test, deploy, and maintain production-quality software.

You do not need to be a cryptography or QKD expert. Familiarity with these technologies is an asset, but the primary focus of this role is full-stack software development and integration.

Responsibilities

Design, develop, test, deploy, and maintain full-stack applications and services.
Develop backend services and APIs primarily using Rust.
Develop selected frontend components using Rust and WebAssembly (WASM) where performance, security, or computational efficiency provides a meaningful advantage.
Develop modern web interfaces using TypeScript/JavaScript and appropriate frontend frameworks.
Integrate Rust/WASM components with modern web applications.
Design and implement RESTful and/or real-time APIs.
Design database schemas, queries, migrations, and data-access layers.
Integrate frontend applications with backend services and APIs.
Develop authentication, authorization, session management, and other security-related functionality.
Build reusable, modular, and maintainable software components.
Write clean, well-structured, documented, and testable code.
Develop unit, integration, end-to-end, interoperability, and performance tests.
Diagnose and resolve software, database, networking, and deployment issues.
Participate in software architecture and technical design decisions.
Contribute to code reviews and establish strong engineering practices.
Work with DevOps and infrastructure components to deploy and operate applications.
Monitor application performance, reliability, and security.
Collaborate with backend, systems, cryptography, networking, and infrastructure engineers.
Work with existing systems as well as develop new applications and services from the ground up.

Programming Requirements

Rust: strong professional experience developing production software, preferably including backend, systems, networking, or security-sensitive applications.
TypeScript/JavaScript: strong experience with modern web application development.
HTML5/CSS3: strong understanding of modern web standards and responsive interfaces.
SQL: strong understanding of relational databases and database design.
Python: experience with scripting, automation, testing, or tooling.
Bash/Linux shell scripting.

Frontend Development

Strong experience with modern frontend development using technologies such as:

React
Next.js
Vue.js
Angular
Other modern TypeScript/JavaScript frameworks

The Candidate Should Have Experience With

Responsive web application development

Integrating Rust/WASM modules with TypeScript/JavaScript applications
Managing communication between WASM modules and browser-based application code
Understanding the performance and security characteristics of WebAssembly
Determining when Rust/WASM provides a meaningful advantage over conventional JavaScript/TypeScript implementations

The expectation is not that the entire frontend will be written in Rust. The successful candidate should be able to choose the appropriate technology for each component while maintaining a coherent architecture.

Backend Development

Strong Experience With Backend And Server-side Development, Including

Rust-based web services and APIs
REST APIs and/or other service architectures
Asynchronous and concurrent programming
Authentication and authorization
Session management
Input validation and secure error handling
Service-to-service communication

Experience developing security-sensitive software is an asset. Experience with cryptographic software, secure communications, or QKD-related applications is also an asset, but not required.

Systems & Linux

Strong experience working with Linux
Understanding of processes, threads, concurrency, and system resources
Experience troubleshooting applications at the operating-system level
Understanding of TCP/IP networking
Familiarity with DNS, HTTP/HTTPS, TLS, TCP, UDP, and sockets
Experience with Linux command-line tools
Experience with system monitoring and troubleshooting
Understanding of containerized environments
