Join BlackBerry, Where Innovation Meets Impact
Secusmart, a rapidly growing subsidiary of BlackBerry Limited, is the leading expert in comprehensive anti-eavesdropping solutions for private and government agencies, as well as organizations responsible for emergency services. We secure enterprise information and applications on today's most popular mobile devices and desktop platforms, protecting both business and personal data.
We are looking for an Intermediate Applications Software Developer who is at home in native C and C++ and wants to write the code our secure products are built on. You'll work at the core of our platform — the shared C++ libraries that power secure calling, messaging, and cryptography across every device we ship, and the desktop application that puts those capabilities in users' hands. It's genuine systems-level work: efficient, robust, portable code with a direct line to how governments and enterprises defend against eavesdropping.
What you'll do
Design, build, and maintain the core C++ libraries that form the cross-platform foundation for secure voice (SIP/VoIP), messaging, contacts, call handling, audio, networking, and cryptography
Develop and evolve the C++ backend of our secure-voice desktop client
Write portable code that builds and runs cleanly across Linux, Windows, and macOS — and plays nicely with the mobile clients that share the same C++ core
Work close to the metal: memory and ownership discipline, concurrency, performance, and the cryptographic plumbing our products depend on
Track down and fix the hard bugs — the kind that need a debugger, sanitizers, and a clear mental model of what the machine is actually doing
Keep quality high through testing, code review, and solid engineering habits, and help keep our builds and CI pipelines healthy
Jump into design discussions, share opinions, and help keep the core and the apps consistent
Take an empirical approach to your work — measure, don't guess
Our Technology & Tools
**Languages:** C and C++ (core libraries and application backend)
**Build & tooling:** CMake, GitLab CI, and a modern native toolchain
**Platforms:** Linux, Windows, macOS (with the same C++ core shared into Android and iOS)
**Domains:** real-time secure voice (SIP/VoIP), messaging, and applied cryptography
Modern, AI-enabled engineering tools as part of everyday development
Requirements
Bachelor's Degree in Computer Science, Software Engineering, Electrical/Computer Engineering, or a related field — or equivalent hands-on experience and demonstrable skills
Around 3–5 years of professional experience building and shipping software in C and/or C++
Strong, practical command of modern C++: RAII, smart pointers and ownership, the standard library, and comfort with the language's core features
Solid grounding in core computer science: data structures, algorithms, and a real understanding of memory, pointers, and how code executes
Comfort at the systems level — multithreading and concurrency, and an awareness of cross-platform portability concerns
Fluency with a native toolchain: a compiler, a debugger, and a build system such as CMake
A demonstrated ability to read an unfamiliar codebase, reason about it, and make careful, well-scoped changes
Ability to develop software in agile environments with rapidly evolving priorities
Eagerness and willingness to quickly learn new technologies, tools, languages, frameworks, and operating systems
A builder who enjoys native, systems-level programming and genuinely cares about writing efficient, correct, robust code
A curious problem solver who wants to understand why something behaves the way it does — and then make it better
Someone who can run with a problem on your own, but is happy to ask for help and learn from the people around you
An easy person to work with who values feedback, code review, and sharing what you know — and doesn't mind mentoring or being mentored
Comfortable picking up new tools, unfamiliar codebases, and the odd cross-platform quirk
Someone who enjoys technology outside of work too — building things, tinkering with hardware, contributing to open source, or just poking at something new for fun
Genuinely interested in working on software where security and quality matter and your work has real-world impact
Location & Work Model
This is a hybrid role based out of our Waterloo, Ontario office. You'll split your time between working on-site with the team and working remotely, so you should be within commuting distance of Waterloo.

Nice to have
