Job description

About the role:

As a Senior Security Engineer II in the Platform Engineering team, you’ll play a critical role in securing Forter’s high-scale, real-time decision-making platform. You’ll drive security strategy for customer-facing production APIs while balancing development velocity with robust security controls. If you're passionate about building security into the foundation of fast-moving engineering teams, this role offers the autonomy and impact you're looking for.

You will have the task of improving the company’s security standing by developing security features and deploying security products in the company’s cloud tech stack (account management, network infrastructure, identity, and access management, secret management, security monitoring and automation, and production machine access).

You will represent the Security Team as a point of contact and source of knowledge in Design Review meetings across Engineering; perform threat analysis, define security controls and security KPIs for implementation, and track across the organization.

About the team:

We are a team of experienced security practitioners and hands-on engineers. We manage a complex set of cloud applications and infrastructure, with petabytes of sensitive data in numerous datastores and thousands of cloud compute instances providing the logic for real-time decision making.
The team needs to meet the challenge of sophisticated external attacks in a highly available production system. We work with every engineering team on their level, building new products and features while also re-evaluating and overhauling everything that has been built by the company over the years. Our customers are Forter’s actual e-commerce customer companies, but also the internal R&D teams, Legal, InfoSec, and C-level management. We are enablers by nature, and maintain an excellent working relationship with other teams across R&D.

Why should you join us?

Take an active role with great impact and ownership potential, work independently and within the team to shape the security process across Engineering during an active growth phase of the company.

What you will be doing:

• Own and innovate the security strategy for Forter’s customer-facing APIs, ensuring high availability while mitigating evolving threats.
• Collaborate with engineering teams to embed security best practices early, balancing protection with development velocity.
• Perform risk assessments and negotiate with other teams on where to invest effort.
• Design, build, promote, and maintain security infrastructure and tools used by all of Forter's engineering teams.
• Mentor and build relationships with “Security Champions” in Engineering to design and build secure applications

Who You Are:

• 5-6+ years of experience in the relevant fields:
• 3+ years experience in a security-focused role
• 3+ years working with high-availability production systems in public cloud environments (AWS / GCP / Azure)
• Programming and infrastructure-as-code experience (Python, NodeJS, Go, Terraform, CloudFormation, Pulumi, etc.)
• Deep understanding of security across every layer of the stack (OS, Network, Application, Database, Storage, etc.)
• Excellent communication skills, including the ability to drive cross-team security initiatives

Nice-to-Have

• Experience with threat modeling, security audits, penetration testing, or SAST tools
• Contributions to security research, blogs, talks, or open-source security projects

Benefits include:

• Competitive salary
• Quarterly company bonus
• Private health insurance, including vision and dental coverage
• Restricted Stock Units (RSU’s)
• Generous PTO policy
• Half day Fridays, every Friday
• Work from home allowance
• Pension plan with an option for salary sacrifice
