Experienced Senior Full Stack Engineer to Build & Backend for Event Ticketing Platform Using Claude Code

Overview

We have the frontend already built in Replit for both user and admin experiences. We are looking for a very experienced software engineer to design, build, and scale a production ready backend for a high concurrency event ticketing platform.

This role is for a true senior engineer who actively uses Claude Code as part of their daily development workflow, understands how to review and harden AI assisted output, and can ship systems that hold up under real world load, QA, and security testing.

This is not a prototype or demo system. This backend must be reliable, scalable, secure, and extremely well documented.

What You Will Be Building

• Backend services for an event ticketing platform

• Multi tenant architecture supporting thousands of organizers and events

• High concurrency purchase and checkout flows

• Secure user, admin, and system level access controls

• Production deployments with secrets management, middleware, and security layers

• Observability, logging, and metrics suitable for QA and load testing

• A thoroughly documented backend that future engineers can onboard into quickly

Core Engineering Requirements

• 10 plus years of professional software engineering experience

• Expert level experience using Claude Code or equivalent AI coding agents in real production workflows

• Deep experience building backends with Node.js

• Strong experience with Supabase and PostgreSQL

• Experience deploying and scaling applications on Vercel

• Proven experience extending existing codebases safely

• Strong API design and database performance fundamentals

• Ability to reason clearly about concurrency, transactions, and failure modes

Scalability and Performance Expectations

The backend must be designed to support:

• Hundreds of thousands of ticket purchases

• Thousands of concurrent users and tenants

• Large traffic spikes during on sale windows

• Load testing across all major latency percentiles including p90, p95, and p99

• Extremely low tail latency under high concurrency

• Graceful degradation and recovery under stress

You should be comfortable designing and implementing caching strategies, queue based workflows, idempotent operations, locking mechanisms, and transactional safety.

Security and Production Readiness

You must be able to:

• Set up production environments with proper secrets management

• Implement middleware for authentication, authorization, and rate limiting

• Design secure communication between frontend and backend

• Apply industry best practices for security hardening

• Prepare the system to pass penetration testing

• Maintain clean separation of concerns and least privilege access

Documentation and Developer Experience Requirements

High quality documentation is a hard requirement for this role.

You must have experience:

• Using AI powered documentation tools to generate and maintain technical documentation

• Producing clear architectural overviews and system diagrams

• Writing detailed README files and onboarding guides

• Documenting APIs, data models, and critical flows

• Keeping documentation in sync with code changes over time

We expect the backend to be easy to understand, easy to extend, and well explained for future engineers.

How We Evaluate Candidates

We are looking for engineers who can demonstrate:

• Real production systems they have built or scaled

• Clear judgment in how they use Claude Code and validate AI generated output

• Strong opinions on production readiness backed by experience

• The ability to move fast without sacrificing quality or safety

A short paid technical task may be used that involves real backend work with production quality code and documentation.

Responsibilities:

• Design, build, and maintain efficient, reusable, and reliable code with full-stack development in PHP.
• Roll out new features and analyze (and react) to the results you discover from our system services and user feedback
• Optimize existing functionality for improved response times
• Collaborate with the team to design, develop, unit test, and support new features
• Searching creatively for the best solution while building for the end-user
• Consistently deliver readable, maintainable, and efficient code
• Performance tuning, testing, refactoring, usability, and automation
• Participate actively in Scrums, sprint planning meetings, and sprint retrospectives.
• Rapidly mockup-proof-of-concept implementation of ideas and present them to internal stakeholders
• Stay informed of new tools, libraries, and best practices and share ideas with the team for continuous improvement of the toolchain and development process
• Support, maintain, and help document software functionality
• Work with other departments, stakeholders, and customers on software development, improvements, internal tools, and implementation issues

Basic Requirements:

• 5+ years of programming experience in developing web apps. Experience in developing mobile apps would be a bonus.
• Front-end development with technologies such as Javascript, Typescript, VueJS, CSS, Bootstrap, etc
• Strong knowledge of database modeling and design in RDBMS and NoSQL databases
• Strong experience in API design, API Security, API Documentation and REST, GraphQL-based services
• Knowledge of Service Oriented Architecture would be a bonus
• Have a self-directed work ethic with attention to detail and good communication skills
• API Integration and extension development for 3rd party applications e.g. Facebook, Google, etc
