Job Title: Senior Backend Developer
Location: Noida
Working Mode: Remote
Type: Full-time
Experience: 4-5 Years
About the Company:
weya AI builds AI automations - Voice, video and WhatsApp agents that banks, lenders and insurers put in front of their customers. Our agents handle collections, onboarding, renewals, KYC follow-ups and support calls at scale, across India, the Middle East & Africa, Australia and the US. We're a small team of 11-15 people. Every engineer ships to production, talks to customers, and owns real outcomes. If an agent mishandles a loan call, it costs a client money and trust, so we build for reliability first.
About the Role:
As a Senior developer at weya, you’ll join our core tech team and take full ownership of backend systems that power our real-time AI communication stack. This isn’t just a development job - it's a leadership opportunity to help scale a live product already in production. You'll architect, build, and optimize scalable, secure backend services while collaborating across AI, frontend, and telephony teams. Expect rapid release cycles, close collaboration with founders, and the freedom to influence architecture, tooling, and team culture.
What You'll Own?
- Architect and build scalable microservices using Go and Node.js
- Design clean, secure APIs and data pipelines for real-time voice and chat systems
- Manage cloud infrastructure on Azure or AWS (App Services, containers, databases)
- Optimize backend systems for performance, cost-efficiency, and reliability
- Collaborate with AI & Engineering teams to launch new features rapidly
- Own deployments, monitoring, and backend stability in a production environment
- Contribute to code reviews, system design decisions, and long-term architecture strategy
Requirements
What We're Looking For?
- We’re looking for someone with hands-on experience building and scaling systems from scratch, including owning 0→1 product development and scaling them reliably in production environments.
- Atleast 3+ years of backend or full-stack experience with Go (Golang), Node.js, React, PostgreSQL or MongoDB
- Strong understanding of system design, microservice architecture, and clean code practices
- Experience deploying and scaling cloud applications on Azure or AWS
- Proven track record of delivering end-to-end features in SaaS, voice tech, or AI-driven platforms
- A product-first mindset - you think about UX and business impact, not just code
- Strong communication, ownership, and cross-functional collaboration skills
- A self-starter attitude - you thrive in startup environments and ambiguity
Good to have (Bonus Points):
- Exposure to Next.js, or frontend integration workflows
- Familiarity with CRM integrations, WhatsApp APIs, Twilio, or Knowlarity
