Backend Lead

The Backend Lead will own Invisia's core server-side systems: the booking engine, availability and inventory logic, payments flow, and the APIs that power everything from the mobile app to third-party integrations. You will be the technical anchor for backend engineering: setting the standard, mentoring the team, and making the key system design decisions.

This is a high-ownership role. You will not just be contributing features; you will be the person who decides how the backend scales, what the data model looks like, and how the team approaches reliability. You will work closely with the Frontend, Mobile, and DevOps functions to ensure the platform performs under real-world load.

The core responsibilities for the job include the following:

System Design and Ownership:

• Design and evolve APIs, data models, caching strategies, and message queue architectures across Invisia's core backend services.
• Own the performance and reliability of backend systems, set SLOs, monitor dashboards, and proactively address degradation before it impacts users.
• Make the key decisions on database choice, query optimization, indexing strategy, and data partitioning as the platform scales.
• Lead the design of Invisia's payments integration, ensuring security, reliability, and reconciliation accuracy.

Engineering Quality and Standards:

• Set and enforce backend coding standards, testing requirements (unit, integration, contract), and observability practices.
• Lead backend code reviews; give feedback that improves code quality and helps engineers grow.
• Own backend-specific postmortems; ensure root causes are identified and systemic fixes are implemented, not just patched.

Team Leadership and Mentoring:

• Mentor and technically guide backend engineers at junior and mid levels.
• Participate in backend hiring, define the bar, conduct technical interviews, and provide calibrated feedback.
• Collaborate with DevOps to right-size infrastructure, optimize cloud spend, and maintain deployment reliability.

Requirements:

• 6-10 years of backend engineering experience with clear examples of owning and scaling complex systems.
• Deep proficiency in at least one strongly typed backend language (Java, Go, Node.js/TypeScript, or Python) and comfort reading others.
• Strong command of relational and non-relational databases; you know when to use each and how to optimize both.
• Hands-on experience with caching layers (Redis or similar) and message brokers (Kafka, RabbitMQ, or equivalent).
• Payment gateway integration experience you understand the reliability, idempotency, and reconciliation requirements that come with money movement.
• Experience building and maintaining RESTful and/or GraphQL APIs at production scale.

Nice to Have:

• Experience building booking, availability, or inventory management systems.
• Familiarity with event-driven and CQRS patterns.
• AWS-specific experience (Lambda, RDS, ElastiCache, SQS/SNS, API Gateway).
