We are currently seeking a Senior Application Security Engineer to join our rapidly growing Security team. The Application Security team is responsible for emulating real-world adversaries to proactively discover, exploit, and help remediate critical security vulnerabilities across our applications. We provide an essential adversarial perspective, challenging our defences and partnering with development teams to eliminate flaws before they can be abused.

This role is for someone who is passionate about building innovative solutions and being exposed to new challenges and technologies while making an impact. This role can be performed from one of our Canadian offices, remotely across Canada, or a combination of both. Some exceptions may apply.

A day in the life might look like:

  • Build partnerships with development teams and advise on security best practices;

  • Provide detailed guidance and support to teams in vulnerability remediation, and develop frameworks, guidelines, and systematic fixes for recurring vulnerabilities;

  • Resolve issues, navigate ambiguity, and maintain positive working relationships with researchers in our Bug Bounty program;

  • Identify and implement tools for automated application scanning, static analysis and related tools;

  • Perform penetration testing, and offensive campaigns against internal assets;

  • Perform reactive incident response and forensics when a security event occurs;

  • Perform proactive research to detect new attack vectors;

  • Elevate and educate our security culture within Clio, contributing to our cultural values;

What you may have:

  • Experience in Application Security, with a strong focus on offensive security and penetration testing

  • hands-on expertise identifying and exploiting complex vulnerabilities (e.g., SSRF, Deserialization, logic bypasses)

  • Proven ability to lead and conduct formal threat modeling sessions

  • Strong proficiency in at least one major programming language (e.g., Python, .NET, JavaScript)

  • Experience securing applications in modern cloud environments (AWS, Azure, or GCP)

  • Expertise with common application security tools and platforms (e.g., Burp Suite, SAST, SCA)

  • Experience with log aggregation and SIEM technologies

  • Ability to identify malicious behaviour and emerging threats via log analysis

Serious bonus points if you have:

  • Security certifications such as OSCP or OSWE

  • Active participation in the security community (e.g., presenting at conferences, contributing to open-source tools).

  • Experience with Ruby on Rails, Puppet, Kubernetes, Terraform, ELK (Elastic, Logtash and Kibana)

  • Strong AWS security experience on EC2 and managed services

  • Infrastructure security (WAF, ACLs, authentication, device hardening)
