Original job description

Hi there! Thanks for stopping by 👋

Are you actively looking for a new opportunity? Or just checking the market? Well… you might just be in the right place!

As a Senior Application Security Engineer, you will serve as a foundational anchor on the AppSec team, leading our strategic shift hard-left toward developer-embedded security and Secure by Design operationalization. You will design, build, and scale state-of-the-art AppSec practices while collaborating closely with Vulnerability Operations to streamline vulnerability triage and remediation. Leveraging cutting-edge AI-assisted workflows and modern automation, you will eliminate friction for developers, burn down legacy risks, and fortify software lifecycles against sophisticated, emerging threat vectors.

What you’ll be doing:

Operationalize Secure by Design principles end-to-end, embedding seamless security controls directly into feature designs, pull requests, IaC checks, and daily engineering workflows.
Architect high-impact feature and infrastructure threat models, validating and enhancing advanced AI-generated threat modeling pipelines.
Configure, fine-tune, and orchestrate SAST, DAST, SCA, Secrets, and LLM scanner rulesets to eliminate false positives and streamline Vulnerability Operations.
Build and stabilize new AppSec processes and ways of working while ensuring legacy security controls remain fully active.
Pioneer AI-driven automation to dramatically accelerate vulnerability triage and remediation, systematically burning down security backlogs.
Provide hands-on technical fix guidance to developers for complex structural flaws and web application vulnerabilities.
Drive developer security enablement across the organization - championing our Security Champions program and delivering engaging, impactful secure coding workshops.
Partner closely with Platform and Infrastructure Security teams to build frictionless, automated guardrails into CI/CD pipelines.

What you need to bring:

Deep, hands-on experience in Application Security, Product Security, or Secure Software Engineering in high-growth cloud environments.
Bachelor's degree in Computer Science, Cybersecurity, or Software Engineering, or equivalent practical experience.
Deep understanding of web application vulnerabilities (OWASP Top 10), business logic flaws, and secure coding practices.
Proven track record tuning SAST, DAST, SCA, Secrets, and LLM scanner pipelines in CI/CD environments.
Demonstrated experience with threat modeling methodologies, Secure by Design principles, and guiding developers through code remediations.
Proven experience leveraging AI/LLM tools to automate security analyses, accelerate triage, and optimize developer security workflows.
Fluency in modern software development languages (e.g., Python, Go, JavaScript/TypeScript, Java).
Excellent cross-functional influence and communication skills to effectively lead the Security Champions program.

What’s in it for you:

Join a growing team and help us move to the next level
Amazing benefits & perks, including equity for all Lightspeeders
Constant development of both your skill-set and business acumen with limitless growth opportunities
Lots of autonomy, flexible work culture
Innovation time to explore and learn at work
Shaping the company by joining cultural & technical committees
Tons of growth opportunities into technical or people management roles
Opportunity to join a fast-paced, high-growth company
Opportunity to learn, expand your skill set, forge wonderful relationships and make your mark within the diverse and inclusive Lightspeed family, a true Canadian tech success story

…. And enjoy a range of benefits that will keep you happy, healthy and (not) hungry.

Lightspeed equity scheme (we are all owners).
Flexible paid time off and remote work policies.
Health insurance.
Contributions to your pension plan - RRSP.
Health and wellness benefit of $500 per year.
Paid leave and assistance for new parents.
Mental health online platform and counseling & coaching services.
Training opportunities to grow your skills and career
Volunteer day.
Fully stacked kitchen (hot and cold beverages, meals served)
Happy hours to build your relationships with colleagues after work
