Principal Software Engineer, Site Reliability

Location: Bucharest Workplace: OnSite LIFE AT UIPATH The people at UiPath believe in the transformative power of automation to change how the world works. We’re committed to creating category-leading enterprise software that unleashes that power. To make that happen, we need people who are curious, self-propelled, generous, and genuine. People who love being part of a fast-moving, fast-thinking growth company. And people who care—about each other, about UiPath, and about our larger purpose. Could that be you? YOUR MISSION At UiPath’s Site Reliability team, we build the platforms and systems that the entire company depends on to deliver on our compliance and SLA promises to customers. This spans monitoring, alerting, cloud infrastructure, access management, standardized synthetics, performance and test validation, incident detection and status reporting, incident management, automated remediation, structured post-mortems, customer communications, repair item tracking, and assertion of engineering best practices across UiPath. We are scaling each of these pillars - and building the next generation of capabilities on each, increasingly powered by AI. This is a software engineering role. You will not be the person who identifies a reliability gap and files a ticket for another team to fix. You are the engineer who identifies the gap, designs the system that closes it, builds it, ships it, and drives its adoption - often by doing the integration work yourself rather than asking other teams to come to you. You build platforms that other engineers depend on in their critical path, and you hold yourself accountable to outcomes, not outputs. You treat every system you ship as a product: you put it in front of users early, seek feedback, and iterate until it delivers real results. If adoption is slow, you don’t blame the docs - you sit with the team, understand the friction, and remove it. WHAT YOU'LL DO AT UIPATH - Design, engineer, and build SRE platform systems and capabilities with cutting-edge AI, treating them as products that other engineering teams depend on in their critical path. - Participate in livesite monitoring rotations, handle escalations, and drive effective mitigations - reducing customer impact through broad, detailed, and effective post-mortems. - Drive availability, scalability, and performance improvements based on livesite learnings. Generate (or codify existing) best practices and ensure they are followed widely across UiPath - not by publishing guidance, but by embedding them into the systems you build. - Ensure technical deliverables meet or exceed expectations on reliability, scalability, quality, and performance. Identify and drive architectural changes that significantly move the needle on these dimensions. - Onboard other teams onto your platforms by driving outcomes yourself - writing the integrations, pairing with their engineers, removing friction - rather than handing off documentation and waiting. - Ship early, seek feedback relentlessly, and iterate fast. Treat every user complaint as a design input, not a support ticket. - Drive task planning, estimation, scheduling, and staffing. - Mentor Software Engineers to develop their skills and knowledge through hands-on coaching, advice, and training opportunities. - Participate in and influence process improvements and best practices across the engineering organization. WHAT YOU'LL BRING TO THE TEAM - Proven track record (10+ years) of architecting and engineering world-class, large-scale, distributed commercial applications and services, and ensuring customer success. - Experience building large-scale, complex internal platforms adopted by 10+ teams in their critical path at a large company — systems that have stood the test of time, not prototypes that were handed off or abandoned. - Demonstrated ability to drive adoption of your systems by doing the hard work yourself: writing integrations, removing friction for other teams, and measuring success by outcomes delivered - not features shipped. - Experience building and maintaining complex AI-powered applications in production. - Proficiency in one or more object-oriented languages (such as C#, C++, Java, or Python), backed by solid computer science fundamentals. - Deep understanding of data structures, algorithms, multithreading, synchronization, asynchronous patterns, and cloud programming. - Experience with service-oriented and microservice-based architectures, HTTP applications, and web services development. - Familiarity with modern engineering practices including agile development, CI/CD, and DevOps. Ability to work with globally distributed teams. - Experience working with or managing production Kubernetes infrastructure is a plus. - Experience with cloud providers (Azure, AWS, GCP) and managed services (AKS, GKE, etc.) is a plus. - Experience with database backends (e.g., Azure SQL, CosmosDB, Azure Data Lake, Power BI, MongoDB, MySQL, DynamoDB, etc.). Maybe you don’t tick all the boxes above—but still think you’d be great for the job? Go ahead, apply anyway. Please. Because we know that experience comes in all shapes and sizes—and passion can’t be learned. Many of our roles allow for flexibility in when and where work gets done. Depending on the needs of the business and the role, the number of hybrid, office-based, and remote workers will vary from team to team. Applications are assessed on a rolling basis and there is no fixed deadline for this requisition. The application window may change depending on the volume of applications received or may close immediately if a qualified candidate is selected. We value a range of diverse backgrounds, experiences and ideas.
