Job Description

As a Software Engineer in OutSystems R&D, you’ll contribute to the next generation of our mobile CI/CD platform — the system responsible for building, packaging, and delivering mobile apps used by thousands of developers worldwide. This is a great opportunity to work across different layers of our technology stack: from cloud infrastructure and API development to automation and orchestration of distributed systems. You’ll collaborate closely with experienced engineers, contributing to services built with C# (.NET Core) and Python, deployed on AWS and orchestrated with Kubernetes. You’ll be part of a team that values learning, curiosity, and continuous improvement. We don’t expect you to know everything from day one — we expect you to want to learn, grow your technical depth, and take on increasing responsibility over time. If you’re eager to work with modern technologies, understand how large-scale systems operate, and build a solid foundation for your engineering career, this is the role for you.

Job Responsibility

  • Design, develop, and maintain backend services that power our mobile CI/CD platform
  • Participate in the full software development lifecycle — from design and implementation to testing, deployment, and monitoring
  • Write clean, efficient, and well-tested code in C# (.NET Core) and Python
  • Collaborate closely with your teammates on design and code reviews, sharing and receiving feedback
  • Help improve our build and deployment automation to ensure fast, safe, and reliable releases
  • Monitor and optimize the performance and scalability of the services you work on
  • Contribute to troubleshooting and incident response, supporting high availability and reliability, having on-call support rotation
  • Stay curious — keep learning new technologies and proposing improvements to our processes and tools

Requirements

  • Bachelor or Master's Degree in Software Engineering, Computer Science, or similar. Equivalent experience in software development will also be considered for exceptional candidates
  • 2-4 years of software development experience
  • Solid coding skills in C# (.Net Core) and Python
  • Basic understanding of cloud platforms (AWS) and container orchestration (Kubernetes)
  • Mastery of continuous delivery and testing techniques
  • Ability to work effectively in a cross-functional, agile environment
  • Availability to participate in an on-call rotation
  • An active learner of emerging technologies and frameworks, eager to stay at the forefront of technological advancements
  • Good troubleshooting skills, with a knack for diagnosing and resolving intricate issues quickly and effectively
  • Motivation to grow your technical skills, take ownership of your work, and contribute to team success
  • Adaptable and flexible, comfortable working across various parts of the technology stack, and embracing new challenges in a fast-paced environment

Nice to have

  • Experience with other languages such as Node.JS, TypeScript, or Ruby
  • Exposure to mobile build tools or automation frameworks like Fastlane
  • Interest in distributed systems, scalability, or reliability engineering
