Principal Software Engineer

About the Team:  

The Intelligent Workflow Engineering organization is at the core of ServiceNows Automation and AI-native Platform vision. We design and deliver the next generation of flow orchestration automation and decisioning capabilities that power how enterprises digitize and optimize their work. Our portfolio includes foundational products such as Flow Designer and the Flow Engine Process Automation Designer Playbooks Decision Management RPA and WebAgent Automations Process and Task Mining Notifications Adoption Services and Document Management. Together these form the Automation suite the backbone of how customers build run and scale automations on the Now Platform. We combine deep expertise in workflow execution AI-driven orchestration and distributed system design to enable the vision of Anybody can Automate Anything from Anywhere using the Power of AI. Our systems are the execution fabric behind billions of transactions daily integrating AI analytics and intelligent decisioning to deliver hyper-scalable reliable and data-aware automation experiences for our customers. 

The Opportunity: Principal Software Engineer 

We are looking for a Principal Software Engineer to help define architect and build the next-generation Workflow Automation Engine that powers the Now Platform and help accelerate our vision for Intelligent enterprise automations of the future.  

In this hands-on highly technical leadership role you will be a key driver in scaling our Flow Engine orchestration framework and automation intelligence stack to support complex AI-native enterprise workloads. Youll lead cross-functional initiatives that blend workflow automation agentic AI and process intelligence shaping how our customers design and execute automations with simplicity and intelligence. Youll influence system architecture performance optimization and reliability strategies across Flow Designer Process Automation Designer Playbooks and RPA and our other offerings. This is a unique opportunity to operate at the intersection of large-scale backend engineering and applied AI working with world-class engineers and researchers to push the boundaries of automation. Your work will directly impact how thousands of our customers create manage and optimize workflows making the Now Platform faster smarter and more autonomous. 

What you get to do in this role:

• Lead the architecture design and evolution of our core backend and workflow engine frameworks ensuring they are highly scalable performant and resilient across millions of transactions and automation flows. 

• Drive major initiatives related to the integration of AI automation and flow orchestration into our platforms core engine enabling next-generation intelligent workflows. 

• Evaluate design and champion distributed systems architectures messaging frameworks and data persistence strategies that ensure low-latency high-throughput performance at enterprise scale. 

• Mentor and guide engineers across multiple teams fostering a culture of technical depth performance-first thinking and engineering excellence. 

• Collaborate with product managers architects and UI engineers to translate complex workflow and automation requirements into elegant extensible and fault-tolerant backend systems. 

• Champion observability reliability and efficiency through strong design principles metrics-driven performance tuning and advanced debugging practices. 

• Build high-quality clean modular and reusable code by enforcing best practices around system design API contracts testing and code reviews. 

• Work with product owners and AI/automation leads to own features end-to-end from architectural design and performance modeling to deployment and continuous optimization. 

• Design and implement backend services that empower customers to build execute and monitor complex workflows at scale while ensuring extensibility and configurability. 

• Contribute to the design and implementation of new workflow engine features and performance frameworks while continuously enhancing the scalability and reliability of the existing ecosystem. 

• Plan lead and execute large-scale backend modernization and re-platforming efforts considering architectural trade-offs system risks and long-term maintainability. 

• You will architect and build core services orchestration engines and asynchronous processing frameworks that power the automation and AI fabric of the platform running both on our infrastructure and across public clouds. 

• Develop robust backend integrations with other systems and services using REST gRPC and event-driven paradigms ensuring secure performant and maintainable interfaces. 

• Collaborate closely with infrastructure and platform engineering teams to optimize deployment pipelines runtime performance and scalability across multi-tenant environments.
