About Rannlab Technologies

At Rannlab, we are on a mission to build intelligent, scalable, and secure technology solutions for businesses and government institutions. Our flagship project a cloud-based Digital Signature Certificate (DSC) platform is transforming how organizations manage eKYC, digital identity, and legally valid document signing. As the product scales, we are seeking experienced engineers who can drive technical excellence and take ownership of mission-critical systems.

About the Role

We are looking for a Senior .NET Full Stack Developer with deep experience in building secure, scalable SaaS platforms using ASP.NET Core, Angular, and PostgreSQL. This role requires strong fundamentals in system design, database optimization, and third-party API integration. Experience with AI/ML integration and digital signature algorithms will make you an ideal fit.
You will work closely with leadership and engineering teams to stabilize the current platform, enhance its performance, and ensure it is ready for enterprise-scale deployments.

Key Responsibilities

  • Lead full-stack development using ASP.NET Core, C#, and Angular (v10+)
  • Architect and enhance a multi-tenant SaaS platform with security and scalability in mind
  • Optimize and manage PostgreSQL databases (indexes, slow queries, schema refactoring)
  • Integrate and manage third-party APIs for identity verification, eKYC, payment, and signing workflows
  • Implement robust exception handling, monitoring, and logging practices
  • Collaborate on AI integration efforts to automate workflows such as fraud detection, document parsing, and smart validations
  • Ensure compliance with digital security standards, including secure data transmission, encryption, and digital signing algorithms (e.g., RSA, SHA256)
  • Promote clean, testable, and modular code by applying SOLID principles and clean architecture
  • Lead code reviews, mentor junior developers, and uphold engineering best practices
  • Participate in deployment planning and CI/CD pipeline improvements

Required Skills and Experience

  • 8+ years of full-stack development experience in a product or SaaS-based environment
  • Expertise in ASP.NET Core (Web API), C#, and Entity Framework Core
  • Strong frontend development experience using Angular and TypeScript
  • Advanced experience with PostgreSQL, including performance tuning and large dataset handling
  • Solid understanding of eKYC workflows, digital signature algorithms, and data security
  • Proven experience integrating and managing third-party APIs (REST/GraphQL)
  • Familiarity with AI/ML APIs, tools, or libraries for document intelligence or workflow automation
  • Strong knowledge of design patterns, SOLID principles, and secure coding practices
  • Experience with Git, CI/CD tools, and deployment automation

Nice to Have

  • Experience working on Digital Certificate Authority, Aadhaar eSign, or identity verification platforms
  • Exposure to cloud services (Azure, AWS) and containerization tools (Docker, Kubernetes)
  • Knowledge of compliance frameworks like ISO 27001, SOC 2, or IT Act regulations
  • Experience with unit testing, test automation, and QA collaboration workflows

What We Offer

  • A high-impact role in a fast-growing technology product with national relevance
  • Ownership of architecture and platform quality
  • Fast-paced startup environment with rapid growth opportunities
  • Flexible work culture, collaborative team, and a chance to work on AI + Cybersecurity convergence
