Senior Software Engineer

We are looking for a remote Senior Software Developer with deep technical expertise and an owner's mindset.

You will lead the technical direction of the platform, currently built with AI-assisted development workflows on a React + Supabase stack. Working directly with the product owner, you will audit the codebase, set the architecture and engineering process, review every change before it ships, and carry the product from an AI-generated prototype to a production system - while continuing to deliver features.

What you'll be working on

• Auditing the codebase and producing a remediation plan.
• Tightening the architecture in place - module boundaries, schema and RLS discipline, audit logging, security, tests, CI/CD.
• Gradually migrating off Lovable onto a production-grade architecture.
• Reviewing and hardening code produced through prompt-driven development.
• Shipping new features alongside the migration - AI workflows and integrations with GDS, payments, accounting, and email.

• 7+ years as a senior engineer, including time as the lead or sole engineer on a production product
• Has set architecture and process from scratch and owned production systems.
• Had experience building their own AI-driven apps - ideally taken one to production or migrated an AI-built prototype onto a real stack.
• Daily user of AI coding assistants - knows their failure modes and reviews output critically.
• Strong code review instincts - spots security, performance, and data-integrity issues unprompted.
• Pragmatic on scope and tech debt - knows when to refactor, leave it, or rewrite.

Required skills

• TypeScript and modern React - deep, not surface-level.
• PostgreSQL - schema, indexes, query performance, migrations, and multi-tenant RLS.
• Backend & API design - services, contracts, and third-party integrations beyond BaaS.
• Lovable - building from scratch, migrating off the stack.
• LLM API integration - Anthropic / OpenAI, tool use, structured outputs, prompt engineering.
• Cloud, CI/CD, DevOps - Docker, GitHub Actions, IaC, at least one cloud or modern platform.
• Production security - auth, RLS review, secrets, OWASP, audit logging.
• Testing & observability - clear strategy plus structured logging, error tracking, alerting.
• Comfortable across multiple languages and runtimes, not just Typescript stack.
• Working knowledge of more than one architectural style (services, event-driven, serverless).

Preferred skills

• Supabase in production - Edge Functions, RLS, Storage, Realtime.
• Stripe in production - payment links, webhooks, off-session, surcharge logic.
• GDS APIs (Sabre, Amadeus, Travelport).
• Production experience with accounting and email platform APIs (e.g., Xero, Gmail).

Bonus skills:

• Travel industry domain experience.
• HTML-to-PDF generation.
• Open source contributions., If you want meaningful work on a product with a real market, a clear problem to solve, and the ambition to become the industry standard, let's talk.

The travel agency software market is overdue for disruption. The tools agencies rely on today were built for a different era. They are expensive, overcomplicated, and have not kept pace with what modern software can do, let alone what AI makes possible. Echelon Concierge is building the platform that replaces them. A modern, intuitive booking and operations management system designed specifically for travel agencies, built from the ground up with AI at its core, not bolted on as an afterthought.
