Job Description

As a Lead Backend Engineer in the ODC Studio team, you’ll help shape the experience of thousands of developers worldwide, building intuitive, powerful, and high-performance tools that make modern application development faster and more enjoyable. In this role, you’ll collaborate closely with 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 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. This is an ideal role for a Lead Backend engineer who enjoys shaping end-to-end systems and collaborating on frontend experiences without being frontend-first.

Job Responsibility

  • Collaborate with product managers, UX designers, and other engineers to deliver solutions that balance functionality, usability, and scalability
  • Own features end-to-end: from architecture and technical design to 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 ODC Studio and its ecosystem

Requirements

  • Proven experience (6+ years) as a software engineer building complex, high-impact products or platforms
  • Strong skills in C# (.NET Core)
  • Working knowledge in TypeScript/JavaScript and modern web development frameworks (e.g., React, Angular, or similar)
  • 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)
  • 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

Nice to have

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