About the role

You'll join a growing engineering team and work closely with engineering teams in the US and Mexico to build, deliver, and maintain reliable, scalable software.

This is a fully hands-on individual contributor role for a senior engineer with strong backend expertise in .NET and solid, demonstrated experience building modern frontend applications. While backend engineering will be the primary focus, you should be comfortable working independently across the stack, including React/frontend development, whenever required.

Location: Hyderabad
Work Mode: Hybrid

What you'll do

• Design, build, and maintain robust, scalable backend systems using .NET
• Develop and maintain modern frontend applications using React
• Work across the full stack, taking ownership of features from backend services through frontend implementation
• Design and implement APIs, services, integrations, and other backend components
• Build responsive and maintainable frontend experiences using modern frontend technologies
• Work on authentication, authorization, and SSO integrations where required
• Make sound technical decisions around architecture, implementation, performance, and scalability
• Break down complex technical problems and drive solutions through implementation and delivery
• Collaborate closely with engineering teams in the US, Mexico, and India
• Participate in technical discussions, code reviews, and engineering best-practice initiatives
• Troubleshoot and resolve complex production and engineering issues
• Take ownership of features and deliver high-quality software with minimal supervision

What we're looking for

• 6+ years of professional software engineering experience
• Strong, hands-on experience with .NET / C# and backend engineering
• Demonstrated hands-on experience with React and modern frontend development
• Ability to independently contribute to both backend and frontend development
• Strong understanding of software architecture, APIs, distributed systems, and scalable backend applications
• Experience building and integrating authentication and authorization systems
• Experience with SSO integrations such as SAML, OAuth, or OpenID Connect is highly preferred
• Experience working with databases, third-party integrations, and production-grade applications
• Strong problem-solving skills and a hands-on approach to engineering
• Experience working with distributed engineering teams is preferred
• Strong communication and collaboration skills
• Experience with cloud platforms is preferred

Good to have

• Experience with payment systems or payment-related products
• Experience working with AI/ML-powered products or integrations
• Experience with additional modern frontend technologies
• Experience designing and implementing security and identity solutions
• Experience working in a product-focused engineering environment

Who you are

• You're a hands-on engineer who enjoys building and solving complex technical problems
• You have deep backend expertise but are equally comfortable getting into the frontend when needed
• You take ownership of features and drive them through to completion
• You're comfortable working independently and making sound technical decisions
• You're curious, resourceful, and continuously looking to improve your technical skills
• You communicate clearly and collaborate effectively with teams across different locations
• You care about writing clean, maintainable, and reliable software
