Senior Full Stack Developer

We're looking for a seasoned senior full stack developer to build and scale platforms across India Running, Captured, and Fitpage. You'll own complex backend systems — from ticketing flows and event infrastructure to user data pipelines — while contributing to robust frontends. This is a high-ownership role for someone who moves fast and thinks in systems.

Tech Stack :

Node.js, Express.js, React, MongoDB, REST APIs, VAPT, AWS / Cloud, PostgreSQL

What You'll Do:

• Design, develop, and maintain backend services and APIs for ticketing, registrations, and event management flows
• Build and optimize: REST APIs, database schemas, caching layers
• Own the full development lifecycle — from architecture decisions to deployment and monitoring
• Build and maintain React-based frontends across Fitpage, India Running, and Captured products
• Identify vulnerabilities and ensure platforms are VAPT-compliant and security-hardened
• Optimize performance for high-concurrency scenarios (race day traffic spikes, large-scale registrations)
• Collaborate with product and design teams to ship features fast without compromising quality
• Participate in code reviews and contribute to engineering best practices
• Implement background jobs, retries, and failure handling systems
• Handle high concurrency scenarios (race-day traffic spikes, flash registrations)

What We are Looking For:

• 5+years experience in backend or full stack development particularly strong Node.js backend skills.
• Prior experience with ticketing platforms, booking systems, or other backend-heavy, transaction-intensive products
• Strong expertise in: Node.js + TypeScript, NestJS / Express, REST API design, idempotency & concurrency control
• Hands-on experience with: PostgreSQL / MongoDB (indexing, query optimization), Redis (caching, locks, rate limiting), background jobs / queues
• Experience building: transaction-heavy systems (payments, bookings, ticketing)
• Working knowledge of VAPT (Vulnerability Assessment and Penetration Testing) concepts and secure coding practices
• Ability to own systems independently and operate in a fast-paced environment
• Experience with API design, third-party integrations (payment gateways, SMS/email, etc.)
• Ability to work independently and take full ownership of features and modules
• Comfortable working in a fast-paced startup environment with shifting priorities

Good To Have :

• Experience with race timing systems, sports tech platforms, or event registration products
• Familiarity with DevOps basics — CI/CD pipelines, containerisation (Docker), and cloud deployments
• Exposure to: observability tools (Sentry, SigNoz, etc.)
• Prior exposure to building or scaling multi-tenant SaaS or marketplace platforms
