Original job description

At Kepler Communications, we're not just imagining the future of on-demand space connectivity - we're leading it!

Our mission is to provide real-time on-orbit connectivity for critical missions, enabling a new era of data-driven intelligence and innovation. With 33 satellites launched to date, Kepler operates the first commercial optical data relay constellation, enabling real-time, continuous space communications while supporting advanced on-orbit compute and hosted payload capabilities.

Industry-leading technology is only part of the story. What sets Kepler apart is our team: bold thinkers, skilled builders, and passionate problem-solvers who thrive on pushing the boundaries of what’s possible in space. We believe great ideas come from diverse perspectives, and we’re committed to creating an environment where you can grow, lead, and make a global impact.

If you’re ready to reach higher, move faster, and do work that shapes the future space economy - this is your launchpad. Come build the future with Kepler!

What We Offer:

* Competitive compensation with a robust equity plan to share in our success.

* Comprehensive coverage for health, dental, and vision insurance - including dependents.

* Unlimited vacation, supportive parental leave policy, and company-wide holiday shutdown.

* Semi-annual company-wide parties and frequent in-office team events.

* Relocation packages available for approved roles.

* $1,500 annual professional development fund to support your growth.

* Fully stocked Toronto office kitchen with snacks, drinks, games and top-notch kitchen appliances.

* Town Halls, Celebration Calls, and Company-wide events to stay connected and engaged.

* We’re a certified Great Place to Work®, seven years in a row!

As Senior Infrastructure Security Specialist, you will protect Kepler’s corporate, cloud, and operational infrastructure. Reporting to the VP, Information Security & CISO, you will own and improve infrastructure security capabilities, including vulnerability management, security monitoring, endpoint protection, system hardening, and incident response.

You will partner with IT, Engineering, Operations, and other teams to reduce security risk while supporting Kepler’s growth. The role also supports regulated and Government of Canada environments that may process Protected or Classified information.

This Toronto-based role follows a hybrid model, with approximately 40% of time spent on-site.

\nKey Responsibilities:

Infrastructure Security

Provide security expertise for infrastructure, cloud environments, networks, systems, databases, and identity technologies
Review architectures and infrastructure changes to identify risks and recommend practical controls
Develop secure configuration and hardening standards based on CIS Benchmarks, NIST guidance, and industry best practices
Support network security controls, including firewalls, segmentation, secure remote access, and intrusion detection and prevention
Partner with IT and Engineering to incorporate security into infrastructure design and operations

Vulnerability Management

Own Kepler’s infrastructure vulnerability management program
Manage authenticated scanning, validate coverage, assess findings, and prioritize remediation based on risk
Coordinate remediation with system owners and track vulnerabilities through resolution or approved risk acceptance
Measure vulnerability exposure, remediation performance, scanning coverage, and exceptions
Administer platforms such as Tenable or equivalent technologies

Security Monitoring and Endpoint Protection

Own and improve Kepler’s SIEM, security monitoring, and EDR/XDR capabilities
Integrate log sources and develop detection use cases across infrastructure, cloud, applications, identity, and security tools
Monitor logging coverage, platform health, and detection effectiveness
Investigate security alerts and support containment, remediation, and recovery
Coordinate investigations and service improvements with Kepler’s MDR/SOC provider
Administer platforms such as Securonix, SentinelOne, or comparable technologies

Incident Response, Cloud and Automation

Support incident investigations involving infrastructure, endpoints, networks, identity, and cloud environments
Analyze security telemetry, collect evidence, and coordinate containment and recovery
Assess and improve security controls within AWS and/or Microsoft Azure
Identify opportunities to automate monitoring, vulnerability management, and security operations using scripts, APIs, and security tools

Government and Regulated Environments

Implement technical controls for Government of Canada and other regulated environments
Support audits, security assessments, inspections, certifications, and remediation activities
Maintain documentation and evidence demonstrating that required security controls are operating effectively

Required Skills & Qualifications:

Seven or more years of cybersecurity experience in infrastructure security, security engineering, or security operations
Strong knowledge of Windows, Linux, networking, cloud platforms, and enterprise IT security
Strong hands-on experience administering and operating vulnerability management, SIEM/security monitoring, and EDR/XDR technologies
Experience investigating and responding to cybersecurity incidents
Knowledge of network security, infrastructure hardening, identity and access management, privileged access, and least-privilege principles
Experience securing AWS and/or Microsoft Azure environments
Familiarity with NIST CSF, NIST SP 800-171, NIST SP 800-53, and CIS Controls and Benchmarks
Ability to communicate technical risks and recommendations to technical and non-technical stakeholders
Strong ownership, problem-solving, organization, and cross-functional collaboration skills
Ability to obtain and maintain an appropriate Government of Canada security clearance

Bonus Points:

Experience with Tenable, Securonix, SentinelOne, or comparable platforms
Experience working with an MDR, MSSP, or SOC provider
Experience supporting Government of Canada contracts or environments handling Protected or Classified information
Familiarity with ITSG-33, ITSP.10.171, the Canadian Program for Cyber Security Certification, and the Contract Security Program
Experience with security audits, compliance activities, Python, PowerShell, Bash, APIs, or infrastructure as code
Relevant certification such as CISSP, GIAC, CCSP, Security+, CISM, or CISA
Relevant degree or an equivalent combination of education and professional experience

What Success Looks Like:

You will strengthen Kepler’s infrastructure security without unnecessarily slowing the business. Vulnerabilities will be effectively remediated, monitoring will provide appropriate visibility, incidents will be investigated quickly, and environments supporting sensitive government programs will meet applicable security requirements.

$114,000 - $164,000 a year

Actual total compensation will be determined at the Company’s discretion and is based on a variety of job-related factors, which may include, but are not limited to, relevant knowledge, skills, experience, performance, and education and/or training. The Company encourages all qualified applicants to apply, even if the posted salary range does not align with their expectations, as it does not reflect our total compensation package. Job Type: This is for a current vacancy
