Principal Software Engineer

Role Overview You’ll be the Principal Software Engineer driving the next generation of a large-scale enterprise SaaS platform. In this role, you combine deep hands-on engineering with high-impact technical leadership, shaping how cloud-native and AI-enabled products are designed and built. You’ll design and deliver secure, scalable, serverless systems on AWS using TypeScript and Node.js, modernize critical platform components, and set the technical direction for multiple teams. You’ll also lead how AI capabilities are integrated across the product ecosystem, ensuring they are transparent, observable, and compliant. If you enjoy system-level thinking, complex distributed architectures, and mentoring senior engineers while still staying close to the code, this role gives you company-wide impact and the opportunity to define the long-term technical vision. Here’s a breakdown of what you’ll do (not all of it, just the important stuff) Lead the architecture and delivery of secure, scalable, serverless applications on AWS using TypeScript/Node.js. Define and evolve the platform architecture, driving modernization, performance, resilience, and maintainability. Design and operate distributed, event-driven systems using services like Lambda, DynamoDB, Aurora, S3, and EventBridge. Shape and implement AI-enabled solutions, embedding governance, observability, and responsible AI practices into the platform. Own Infrastructure as Code (e.g., Terraform, AWS CDK, CloudFormation) to reliably provision and manage cloud infrastructure. Mentor senior engineers, influence technical decisions across teams, and clearly communicate complex concepts to diverse stakeholders. These are the essentials you’ll need to get an interview Extensive experience (typically 12+ years) building secure, production-grade software systems. Proven track record architecting and delivering cloud-native, serverless applications on AWS. Strong expertise in Node.js, TypeScript, REST API design, and at least one modern front-end framework (Angular or React). Deep understanding of distributed systems and data stores such as Aurora, DynamoDB, and S3, including event-driven architectures. Hands-on experience with Infrastructure as Code tools (Terraform, AWS CDK, or CloudFormation), plus Docker and modern CI/CD. Strong SQL skills, including performance tuning and optimization at scale. Solid understanding of AI fundamentals (model behavior, prompt engineering, AI safety/governance) and experience building or integrating AI-powered systems with monitoring and compliance in mind. It would be great if you had these too, but we’ll support you if you don’t Experience acting as a trusted technical advisor across multiple teams or product areas. Background mentoring teams through AI adoption and platform modernization initiatives. A degree in Computer Science, Engineering, Mathematics, or a related field (or equivalent practical experience). *** Only Bangalore Based Candidates May Apply About Us Diligent is the AI leader in governance, risk and compliance (GRC) SaaS solutions, helping more than 1 million users and 700,000 board members to clarify risk and elevate governance.
