DAT is looking for a self-driven, passionate, and experienced Senior Software Engineer to join our Account Management & Customer Support domain team within our Identity & Access Management (IAM) umbrella in Bangalore, India.

At DAT, our leaders optimistically share future possibilities to inspire and motivate others toward their full potential. We expect our employees to find ways to embrace positive change, be curious, challenge the status quo, and provide solutions to unmet problems.

The Role 

We are looking for a Senior Software Engineer to lead the design and development of production-grade, consumer-facing, and internal web applications within our Identity & Access Management (IAM) umbrella.

You must be passionate about building resilient full-stack applications in a TypeScript ecosystem (Node.js/Angular). A critical component of this role involves supporting the migration of legacy TypeScript/JavaScript hybrid services and minor Java monolith modules into modern, scalable TypeScript microservices. 

You will work with product managers, UX designers, engineering managers, and other engineers to deliver customer-centric solutions. As a technical leader on a highly collaborative team, you will drive certain architectural decisions and mentor fellow engineers while delivering solutions through our AWS-hosted CI/CD environments.

Candidate Profile

• Deliver customer value: You are customer-obsessed and validate the trust our customers put into our platform. You lead with curiosity to deeply understand complex account management problems before engineering solutions.
• Together we thrive: You embrace diverse backgrounds and perspectives. You thrive working on cross-functional teams and can confidently disagree and commit when a technical or product decision is made.
• Innovate & grow: You have a pulse on the software industry. You champion new technologies and continuously improve the engineering team's workflows and standards.
• Execute with excellence: You recognize that innovation requires operational excellence. You exercise exceptional judgment in balancing technical debt with feature delivery, biasing towards delivering value over analysis-paralysis.

• Architect and Lead: Drive the technical design, development, and maintenance of scalable microservices and robust web applications targeting complex account and user management flows.
• Drive Modernization: Lead and support the strategic migration of legacy hybrid/monolith TypeScript & Java backend modules to modern, highly available Node.js/TypeScript microservices.
• Mentor & Elevate: Actively mentor junior and mid-level developers, fostering a collaborative, knowledge-sharing environment and raising the bar for code quality.
• Code & Optimize: Write modern, clean, efficient, and well-documented code. Troubleshoot complex production issues and optimize applications for high availability.
• Collaborate Cross-Functionally: Partner closely with product managers, UX designers, and analytics to design great user experiences and translate complex business requirements into elegant technical specifications.
• Champion Quality: Establish standard methodologies for unit, integration, and functional testing, and actively lead comprehensive design and code reviews.
