Senior Security Engineer

There are NO limits to your career: come shape the future and be part of a truly unique global culture at OutSystems!

About the role

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. You will partner closely with security, engineering, product, support, digital, legal, sales and enablement, and customer teams; to reduce real customer risk, eliminate recurring vulnerability patterns, and enable teams to move faster because security was already part of the plan.

This role is for a seasoned security engineer who can operate with autonomy, apply foundational security practices effectively in our environment, effectively collaborate and adapt their approach as complexity increases. You will be trusted to deliver quality outcomes end-to-end while mentoring junior team members and strengthening security relationships within your scope.

What You’ll Do

• 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.

The Longer Story:

OutSystems enables enterprise teams to build AI-powered applications and agents that reduce manual work, streamline internal operations, and accelerate impact. A proven low-code foundation combined with agentic AI and AI app generation capabilities empowers teams to move up to 10x faster with the assurance of security, scalability, and governance built in.

As the future becomes agentic, our customers need us now more than ever. AI has opened the door to extraordinary possibilities—but inside the enterprise, things are moving fast and feeling chaotic. Some early adopters are making progress in production, but for many, AI tools are sprawling without governance, data isn’t ready, and talent isn’t there yet. Enterprises are still drowning in application backlogs and struggling with legacy systems. But with the right platform, AI doesn’t have to add to the chaos. It can become the breakthrough that brings clarity—and drives real, enterprise-wide impact. At OutSystems, we’ve built that platform, providing the tools necessary for enterprises to overcome these hurdles.

We are looking for passionate, talented, and motivated people to join us in helping our customers build, deploy, and scale apps and agents—fast, helping them accelerate innovation while enabling secure, governed human-AI collaboration.
