Job description

We are looking for a Senior Backend Engineer who can design, build, and evolve complex backend systems for large-scale applications. This role goes beyond feature delivery—you will own backend architecture, data modeling, and system integrations, ensuring long-term scalability, reliability, and maintainability. This is a work-from-office role, ideal for engineers who value close collaboration, whiteboard discussions, and deep technical problem-solving with cross-functional teams.

Key Responsibilities

• Design and implement scalable backend architectures for complex, long-lived applications.
• Define service boundaries, APIs, and integration contracts.
• Build backend systems using Node.js / TypeScript (NestJS or equivalent frameworks).
• Ensure services meet performance, security, and reliability standards.
• Make pragmatic architectural decisions aligned with business needs.

Database & Data Modeling

• Design robust and scalable database schemas.
• Manage database migrations and long-term schema evolution.
• Optimize queries, indexes, and data access patterns.
• Make informed trade-offs between consistency, availability, and performance.

System Integration & Distributed Systems

• Design and implement inter-system communication using REST, GraphQL, events, queues, and webhooks.
• Build and maintain asynchronous processing and background jobs.
• Integrate with internal services, third-party platforms, and external APIs.
• Handle retries, idempotency, error handling, and cross-system data consistency.

Engineering Excellence

• Write clean, maintainable, and testable code.
• Participate actively in in-office architecture discussions and design reviews.
• Review code and provide strong technical feedback.
• Document system designs, architectural decisions, and operational practices.

Required Skills & Experience

• 6+ years of backend development experience.
• At least 2 years working in a startup environment.
• Strong expertise in Node.js / TypeScript (or equivalent backend stack).
• Strong understanding of backend architecture and system design.
• Excellent knowledge of databases: PostgreSQL, MySQL, MongoDB, Redis.
• Experience integrating multiple backend systems
• Solid understanding of API design, authentication, and authorization
• Experience with asynchronous processing and background jobs.

What We’re Looking For (Mindset)

• Thinks in systems, not just features
• Enjoys in-person collaboration and technical discussions
• Comfortable working with complex and evolving requirements
• Strong sense of ownership and accountability.
• Makes pragmatic, well-reasoned architectural decisions
• Enjoys mentoring and raising engineering standards

What Success Looks Like

• Backend systems are scalable, reliable, and easy to evolve
• Databases and integrations are well-designed and maintainable
• Cross-system workflows are resilient under real-world conditions
• The team benefits from strong in-office technical leadership.

Why Join Us

• Work on complex backend systems with real business impact
• Strong work-from-office culture focused on collaboration and learning
• High ownership and architectural influence
• Opportunity to shape backend foundations for future products
• Strong focus on engineering quality and long-term thinking
