Software jobs in Canada

The Communications Security Establishment (CSE) is Canada’s agency responsible for foreign signals intelligence, cyber operations and cyber security. Learn more about our mission.

CSE is the national signals intelligence agency for foreign intelligence and the technical authority for cyber security and information assurance. The Communications Security Establishment Act (the CSE Act) sets out the five aspects of our mandate.

Join CSE for an opportunity like no other at the heart of Canada’s national security and intelligence community. Work in a team that contributes on meaningful projects which have a significant impact on Canada’s security posture (including Cyber Security and Signals Intelligence (SIGINT)) and ensuring the safety of Canadians.

As a software developer you’ll be responsible for finding solutions to interesting and complex technical problems. We’ll provide you with the opportunity to collaborate with others and contribute to a supportive team environment.

We are looking for entry-level, intermediate, and experienced software developers who wish to work in a continuous learning culture, who look to apply and expand their current knowledge, and who are excited to build reliable and creative solutions to meet their clients’ unique needs and fulfill CSE’s mandate.

CSE is seeking passionate people from a diverse range of backgrounds, who will thrive working in an open-minded environment and value the different perspectives of others. If you’re excited about what we do and working with us but are not sure you’re 100% there yet, please don’t let that stop you from applying.

If you cannot apply online or have a disability preventing you from applying online, please inform us by email at careers-carrieres@cse-cst.gc.ca prior to the closing date of this selection process.

We ask you to not discuss your application with others (including on social media) besides your partner, or close family members - who should also be reminded about the need to be discreet.

This external selection process can take up to 12 months and is more comprehensive than that of many other organizations. You’ll have to complete a combination of assessments, including but not limited to various testing, interview, and security clearance processes. During this selection process, rescheduling assessments will be limited because this can create significant delays in processing applications. Therefore, before you apply to this process, we ask that you commit to each assessment phase.

Candidate assessments are conducted in the candidate’s official language of choice.

To address CSE’s current representation gaps, priority may be given to persons who self-declare as belonging to one, or more, designated employment equity groups: women; Indigenous peoples, including First Nations who are status, or registered and non-status, or non-registered, Inuit and Métis; persons with disabilities, including people with a mental health condition and neurodivergent people; and persons from racial or ethnic groups.

Please note the Employment Equity Act, which is under review, uses the terminology Aboriginal peoples and visible minorities.

CSE offers an assessment process that will accommodate any reasonable measures you require to be assessed in a fair and equitable manner. Those measures are available to all candidates during our processes. Information you provide will be addressed confidentially.

All communications with CSE relating to this process, including email messages and telephone conversations, may be used in the assessment of qualifications.

The intent of this process is to fill vacant positions at CSE. The process may also be used to establish a pool of qualified candidates which could be used to staff similar or identical positions with various tenures.

Please note that in an effort to maintain balance between employee development and business needs, candidates who are hired at CSE must remain in their substantive position for a minimum of twelve (12) months subject to operational requirements.

We thank you for your interest in CSE. However, only those selected for further consideration will be contacted.
