About This Role

As a Principal Software Engineer in OutSystems R&D, you’ll help shape the experience of the next generation of AI driven developer capabilities that are offered by our Platform, building delightful, powerful, and high-performance tools that make modern application development faster and more enjoyable.

In this role, you’ll collaborate closely with architects, PMs, designers and fellow engineers to deliver features end-to-end — from technical design and implementation to performance optimization and usability. You’ll tackle complex engineering challenges around user experience, scalability, collaboration, and developer productivity, while ensuring that our users can trust the quality and reliability of the tools they rely on daily.

We’re looking for engineers who are passionate about building outstanding developer experiences, curious about new technologies, and motivated by solving real-world challenges with elegant solutions. 

At OutSystems, you’ll work in an environment that values collaboration, craftsmanship, and continuous learning — while making a direct impact on how the next generation of software is created.

Key Responsibilities 

  • Drive the solution design, implementation, and maintenance of robust, delightful, scalable, and secure core features for our developers building apps on OutSystems.

  • Collaborate with product managers, UX designers, and other engineers to deliver solutions that balance functionality, usability, scalability, and high degree of automation.

  • Own features end-to-end: from architecture and technical design to alignments, coding, testing, deployment, and monitoring in production.

  • Drive engineering excellence by promoting clean code practices, automated testing, performance optimization, and continuous delivery.

  • Mentor and support other engineers, fostering knowledge sharing and a culture of innovation.

  • Stay up to date with emerging technologies and bring forward ideas to continuously improve our engineering.

What You Need To Succeed 

  • Proven experience (10+ years) as a software engineer solving complex problems, and building high-impact products or platforms.

  • Strong skills in TypeScript/JavaScript and modern web development frameworks (e.g., React, Angular, or similar).

  • Strong skills in C# (.NET Core).

  • Solid understanding of software architecture, design patterns, and scalability principles.

  • Experience with cloud-native development (e.g., microservices, containers, CI/CD pipelines, monitoring, distributed systems).

  • Familiarity with building developer tools, IDEs, or productivity software is a strong plus.

  • Knowledge of performance optimization, debugging complex issues, and ensuring product reliability at scale.

  • Excellent collaboration skills, with the ability to work across product, design, and engineering teams.

  • Passion for delivering outstanding developer experiences and helping others build great software.

  • Good communication skills and fluency in English.

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. Founded in 2001, OutSystems has offices in the United States, United Kingdom, the Netherlands, Portugal, Germany, the UAE, Japan, Hong Kong, Malaysia, Australia, India, and Singapore, and of course has a thriving, worldwide community of remote employees.
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.

Working at OutSystems

Our goal is to ensure that OutSystems is a place for bright, happy, and motivated people who share a common purpose and take pride in doing excellent work to pursue our vision of providing the AI-powered low-code development platform enterprise leaders trust to build, secure, and evolve their business applications, agents, and core systems. Our culture is focused on our core values of trust, customer success, innovation, and alignment. Our team members operate with transparency, integrity, and accountability, define success through the lens of the outcomes we deliver for our customers, push the boundaries with excellence, and work together toward our shared vision to deliver on what matters most.
