ABOUT SAHIONEXT TECHNOLOGY PRIVATE LIMITED
SAHIONEXT Technology Private Limited is a fast-growing technology company building innovative, AI-powered products that solve real-world problems. We operate lean, move fast, and care deeply about the quality and impact of what we ship.
ABOUT THE ROLE
We are looking for a Senior Backend Engineer to take end-to-end ownership of our backend systems -- stabilizing, fixing, and scaling a live production codebase.
This is not a role where you will be handed a clean spec and a clean codebase. You will be working in a real, evolving system with live users, and you are expected to dive in, understand it fast, and start contributing without hand-holding. We need someone who treats the system like their own -- tracing issues to their root cause and fixing them properly, not patching symptoms.
RESPONSIBILITIES
- Take end-to-end ownership of backend systems, including architecture, data integrity, performance, and reliability
- Debug and fix root-cause issues in an existing, undocumented codebase
- Design and ship backend features independently, from requirement to deployment
- Fix recurring and systemic bugs at the source rather than applying surface-level patches
- Work closely with leadership on product and technical decisions -- this role carries real ownership, not just execution
REQUIREMENTS
- 4 to 6 years of hands-on backend experience in real, production environments
- Strong expertise in Node.js and Express
- Proficiency with Sequelize 6 (ORM), MySQL, and PostgreSQL
- Experience with AWS and Firebase
- Proven track record of owning systems end-to-end, not just feature work under supervision
- Ability to get oriented quickly in an unfamiliar or imperfect codebase and start contributing without extensive ramp-up
- Debugging-first mindset -- able to trace issues through messy data and code to find the actual root cause
- Ability to work fast without sacrificing judgment, including effective use of AI development tools such as Cursor, Copilot, or Claude
- Strong ownership mindset -- identifies what is broken or inefficient and fixes it without being told
- Genuine care for product quality and end-user impact
- Ability to walk through specific systems you have built, the decisions you made, and the impact they had
GOOD TO HAVE
- Prior experience working on payment systems, including integrity, reconciliation, and reliability around live transactions
- Prior experience at an EdTech company
- Experience mentoring or unblocking other engineers
- Startup or small-team experience with broad ownership across the stack
WHY JOIN SAHIONEXT
- Real ownership -- shape not just the code, but how the product evolves
- Direct access to leadership with fast decision-making and no bureaucracy
- High-impact work that is immediately visible
- Remote-first work environment
