As a Senior Security Engineer on the Application Security team at OutSystems, you will independently deliver meaningful security outcomes across our #1 AI-powered low-code platform, helping ensure that applications, platforms, and agentic capabilities are secure by design and safe by default. In this role, you will own and execute small-to-medium sized security initiatives and deliver significant service components of a large Product Security program.

Job Responsibility:

Independently drive security work across all phases of the SDLC, from early design and threat modeling through implementation, testing, and release
Own delivery of moderately complex security projects or features, adjusting standard approaches as needed to achieve the intended outcome
Partner with engineering and platform teams to secure AI-powered and agentic capabilities, ensuring security considerations are built in early rather than bolted on later
Conduct focused security assessments of applications, APIs, internal services, and platform components using the appropriate depth and methodology for the risk
Contribute to the development and adoption of secure-by-default patterns, guardrails, and paved roads that scale security without increasing friction
Operate and improve security tooling by tuning signal quality, reducing noise, and identifying opportunities to improve effectiveness
Build or extend security tooling and automation to eliminate manual or repetitive work
Clearly communicate risks, tradeoffs, and recommendations to engineering partners in a way that supports informed decision-making
Proactively identify gaps or inefficiencies in security processes and suggest practical improvements aligned with team goals
Mentor junior engineers and new hires, helping them ramp up effectively and understand how Product Security operates at OutSystems
Strengthen stakeholder relationships within your area of responsibility by being reliable, pragmatic, and outcome-oriented

Requirements:

Proven experience in application security within modern, cloud-native environments
Strong foundation in AppSec fundamentals, including secure design, threat modeling, vulnerability triage, and remediation
Ability to independently deliver moderately complex security work end to end
Comfortable working across application, cloud, and platform security within a defined scope
Ability to write, understand, and review code, including building security automation and validating AI- or low-code-generated solutions
Hands-on experience with AWS (required), Kubernetes, and microservices
Clear understanding of penetration testing, red teaming, and purple teaming, and when to apply each

Nice to have:

Practical experience with AI-enabled and automated systems, including understanding how increased autonomy impacts security risk
Hands-on use of AI-assisted development tools to speed up delivery while maintaining security and correctness
Experience contributing to secure-by-default patterns, platform guardrails, and paved roads
Proven ability to improve security tooling by reducing noise and increasing actionable findings
Strong experience with AWS and exposure to Azure
Background working on developer platforms, low-code platforms, or highly automated environments

What we offer:

A company that is always growing, changing, and innovating
Real career opportunities
Work colleagues that are as smart, hard-working, and driven as you
Disrupting the status quo is in our DNA
We ask “why” a lot
Inclusive culture of diversity
