Principal Site Reliability 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

Site Reliability Engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The main goals of SRE are to create scalable and highly reliable systems. Our SREs ensure our production systems' reliability, performance, and scalability while enabling rapid development and deployment of new features and services.

SREs at OutSystems work closely with development teams, acting as an extension of the team, in adopting the reliability tenets with the shared goal of meeting Service Level Objectives (SLOs) and thus delivering a smooth and frictionless Customer Experience.

What you'll do

• Help define and execute the strategic vision and roadmap for the Site Reliability Engineering function.
• Provide leadership and mentorship to more junior SREs, fostering a culture of innovation, collaboration, and operational excellence.
• Collaborate with leadership and other stakeholders to ensure cross-functional alignment.
• Take active participation, collaborate effectively with development teams, and influence the design of a highly reliable and scalable infrastructure, leveraging cloud technologies and industry best practices.
• Collaborate with development teams at all stages of the product development lifecycle to ensure systems are resilient (observable, fault-tolerant, recoverable, scalable) and performant.
• Drive the adoption, definition, and improvement of Service Level Objectives (SLOs).
• Implement monitoring, alerting, logging, and tracing solutions to detect and respond to incidents.
• Oversee incident response efforts, ensuring quick resolution and minimal downtime, and effective RCA/post-mortems.
• Automate every operational task, with a special focus on fast incident detection & recovery.
• Foster a culture of continuous improvement and knowledge sharing.
• Communicate effectively with stakeholders, providing updates on system reliability and performance.
• Champion reliability as a core product feature, not an afterthought.

Qualifications

• STEM degree (BSc, MSc, in Software Engineering/Computer Science or related fields);
• 8+ years of experience in Software Engineering or SRE, ideally within high-growth, cloud-native environments.
• Expertise in Observability: Proven ability to implement SLIs/SLOs and telemetry systems that provide actionable insights into complex distributed systems.
• Cloud Mastery: Deep architectural knowledge of AWS/GCP/Azure, specifically regarding networking, security, and cost-optimization.
• Strategic Impact: Demonstrated success in leading cross-functional initiatives that improved system reliability or developer velocity at an organizational scale.
• System Design & Architecture: Expertise in designing highly available, fault-tolerant distributed systems (Microservices, Event-driven architecture).
• Development: Professional-level proficiency in Go, Python, or Rust, with the ability to contribute to core product codebases and build custom internal tooling.
• Cloud Ecosystems: Deep-tier mastery of AWS, GCP, or Azure (specifically IAM, VPC networking, Transit Gateways, and Cross-region redundancy).
• Orchestration at Scale: Extensive experience managing Kubernetes (K8s) in production, including Custom Resource Definitions (CRDs), Service Mesh (Istio/Linkerd), and Admission Controllers.
• Infrastructure as Code (IaC): Advanced usage of Terraform, CloudFormation, or Spacelift, focusing on modularity, state management, and CI/CD integration for infrastructure.

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.

OutSystems is a truly global company, with more than 850,000 developer community members, 1,700 employees, more than 500 partners, and thousands of active customers in over 75 countries and across 21 industries.

Amongst our customers are some of the world's most recognizable brands across diverse industries—brands like Toyota, Heineken, Bosch, KeyBank, and UCLA. These customers are the reason we have a 4.6 star rating on G2. Their success is ours, and their stories demonstrate tangible ROI and transformational impact. We are a 9x Gartner Magic Quadrant Leader for Low-Code Application Platforms and a multi-year leader in the Forrester Wave. We’re recognized not just as leaders but as visionaries with a strong ability to execute, now extending our leadership into the AI and agentic application development arena.
