Overview

  • Mid-level engineer who owns the production WordPress plugin and new Python services during handover from the outgoing builder. You keep /wp-json/qr/v3 stable for live Dutch realtor tenants, deliver FastAPI work (CCI, integrations, gateway), and mentor junior developers. This is a transition role on our path to React/Next.js (web), Flutter (mobile only), and Python/FastAPI — not a greenfield…
  • Current engineering phase
  • Live revenue runs on the WordPress plugin and embeds qr-widget.js. We use a strangler-fig approach: no big-bang rewrite; APIs stay backward-compatible while we add Python services and, later, Next.js and Flutter mobile clients.
  • About Quality Realty (QR)
  • Quality Realty is an early-stage AI-native SaaS startup building the future of real estate transactions in the Netherlands. We are developing Quality Realty Marketplace (QRM). This voice-first, multilingual platform connects realtors, clients, and service vendors (painters, movers, stagers, energy auditors, etc.) throughout the entire home buying, selling, and rental process.
  • At its core is the AI Native Marketplace Platform (ANMP) — a fully resellable, white-label, multi-tenant marketplace operating system. QR is the first vertical (Dutch real estate), designed from day one to power other local-service marketplaces worldwide.
  • Own day-to-day engineering on the production WordPress plugin (PHP): bug fixes, security hardening, PII/tenant isolation, retargeting, widget orders, Stripe groundwork, and AI Flow/admin improvements — with additive-only schema and API changes so live tenants do not break.
  • Maintain and extend the versioned REST API /wp-json/qr/v3; enforce semantic versioning and deprecation discipline for existing integrations.
  • Build and maintain Python services with FastAPI (e.g. Contract Intelligence / CCI, API gateway routes, webhooks): clean models, auth, error handling, tests, and documentation under Tech Lead architecture.
  • Integrate external services from both stacks where appropriate: Anthropic (Claude) for AI flows, Stripe Connect, Altum (valuations), calendar/email patterns, and preparation for Grok Voice Agent (WebSocket proxying and tool endpoints — primarily Python track; you support integration and WP-side tools).
  • Implement and respect multi-tenant isolation on WordPress (organization_id, roles/capabilities) and on new Python/PostgreSQL work (tenant context, RLS on Cloud SQL where applicable).
  • Contribute to database and migration work: MySQL (plugin) with safe migrations; PostgreSQL on Cloud SQL for new services (Alembic/migrations under review).
  • Mentor junior developers (Junior WordPress/PHP and Junior Backend, part-time) via code reviews, pairing, and knowledge sharing.
  • Collaborate with the BA on specs/acceptance criteria and with the UX designer on admin and AI prompt screens (WordPress today; Next.js designs over time).
  • Participate in testing, debugging, and production monitoring (Sentry, logs, plugin version rollbacks) to maintain reliability for paying tenants.
  • Document handover, API contracts, and technical debt so Next.js and Flutter mobile teams can consume the same APIs later.
  • Your Skills and Experience
  • Required skills & experience
  • 3–5 years of professional software development, with proven ability to own end-to-end features on a live product.
  • Strong hands-on experience with PHP and WordPress plugin development (custom tables, hooks, REST API, Action Scheduler, wp-admin JS integration) — required.
  • Solid experience building REST APIs in Python (FastAPI preferred; Flask/Django acceptable) and working with relational databases (MySQL and/or PostgreSQL).
  • Comfortable reading and extending a large legacy codebase (~600+ PHP files) without unnecessary rewrites.
  • Comfortable designing and consuming JSON APIs, implementing authentication (JWT/OAuth, API keys), handling async operations, and managing environment/configuration/secrets.
  • Good understanding of cloud deployment concepts (containers, serverless, staging vs production, CI/CD basics); GCP exposure a plus.
  • Proficiency with Git and collaborative workflows (pull requests, code reviews).
  • Strong problem-solving and ability to work independently on complex tasks with light guidance from the Tech Lead.
  • Good English communication (written and spoken) for documentation, team discussions, and collaboration with the CTO.
  • Nice to have
  • Experience with strangler-fig or incremental migration from monolith to services.
  • Experience integrating real-time features (WebSockets) or AI/LLM APIs (Anthropic, Grok, OpenAI).
  • Familiarity with Google Cloud (Cloud Run, Cloud SQL, Cloud Storage) or similar.
  • Exposure to multi-tenant SaaS (tenant isolation, configurable rules).
  • CI/CD (GitHub Actions), Docker, monitoring (Sentry).
  • Dutch real estate or proptech domain familiarity.
  • Basic awareness of React/Next.js or Flutter (you do not own mobile/web UI in this role, but you build APIs those clients will use).
  • Why You'll Love Working Here

Benefits

  • Opportunity to own meaningful work on a live SaaS with real tenants and revenue during a critical handover period.
  • Direct collaboration with the Tech Lead and CTO; high autonomy in a small team.
  • Clear path to Senior / Lead responsibility as QR scales and ANMP is licensed to white-label partners.
  • Remote-friendly environment with flexible hours (HCMC-based core team).
  • Competitive salary for mid-level in Vietnam + performance bonuses (details discussed with CTO).
  • Hands-on work with WordPress at scale, FastAPI, GCP, AI integrations, and real-world marketplace problems.
  • Full-time; Wave 1 hire (from June 2026).
  • Reporting line
  • This role reports to the Tech Lead and works closely with the BA, Junior Developer (WordPress/PHP), Junior Backend Developer, UX Designer (part-time), and Data Scientist (part-time). Junior Flutter (mobile) is a separate hire on a later wave.
