There's a Junior Payment Gateway Integration Engineer opening at a company in Vibhuti Khand, Gomti Nagar, Lucknow. It's a part-time, on-site role, paying INR 22,500 a month.
Skills you'll need
You'll be working directly with payment APIs, so comfort reading API documentation and handling authentication flows matters a lot here. Security compliance, specifically PCI-DSS, comes up constantly in payment work, since handling any part of a transaction touches rules around how card data can and can't be stored or transmitted. General REST API skills round out the requirement, since most payment gateway integrations are built on top of standard REST patterns.
None of this needs to be expert-level walking in. This role exists to build that depth on real integration work.
What you'd be doing
- Implement new payment integration features based on project requirements
- Debug and resolve issues with transaction flows, from failed payments to webhook delivery problems
- Document integration logic clearly enough that another engineer could pick it up without you in the room
- Participate in code reviews, both giving and receiving feedback on integration code
A recent bug on the team involved duplicate orders being created for a small number of transactions. It turned out the payment gateway's webhook was retrying delivery after a slow server response, and each retry was treated as a brand-new payment event instead of the same one. The fix involved adding an idempotency check so that repeated webhooks for the same transaction ID are recognized and ignored. Bugs like that show up often in payment work, since gateways are built to retry aggressively when they don't get a fast, clear response.
Qualifications and experience
A bachelor's degree is required for this entry-level role. What matters most in the hiring process is proficiency with the specific tools and frameworks used day-to-day, so coming in with some hands-on API work, even from a personal project, is genuinely valuable. This role requires 9 months of relevant experience.
Pay and benefits
The role pays INR 22,500 a month for part-time work. Benefits, listed through Naukri Mitra, include pro-rated paid leave, flexible in-office scheduling, and performance-based incentives tied to integration quality and delivery. Since the position is on-site in Gomti Nagar, relocation assistance and accommodation support are also available for candidates relocating from elsewhere.
How the part-time schedule works
Hours flex around core team check-ins and code review sessions, which suits someone juggling studies, another commitment, or simply preferring a lighter weekly schedule while still getting real, hands-on engineering experience.
Applying
Send a resume along with any project, coursework, or personal build that touched a payment API or handled sensitive data securely. If you've integrated a payment gateway before, even for a small side project, describe what you built and what you learned from it. Candidates who move forward will discuss a real integration scenario during a short technical conversation rather than a formal exam.
