Description

About the Role


We're looking for a senior-level engineer who can own the full stack — from database architecture to AI-driven workflow automation to production infrastructure — with no handholding required. This is not a role for someone who specializes in only one layer of the stack. You'll be expected to design systems end-to-end and take ownership of live production environments from day one.


Key Responsibilities



  • Architect and deploy AI-powered automation platforms using n8n multi-agent workflows integrated with REST APIs, LLM services (OpenAI, Gemini, Claude), and NocoDB data layers

  • Design, normalize, and optimize enterprise-grade relational databases (SQL Server, MySQL) — including stored procedures, triggers, indexing strategies, and query performance tuning for high-volume production systems

  • Build and maintain full-stack applications using Python, ASP.NET/VB.NET/C#, and modern JavaScript

  • Administer VPS/Linux production environments: Docker container orchestration, DNS, SSL provisioning, and infrastructure monitoring

  • Build and scale WordPress/WooCommerce e-commerce platforms with custom Elementor theming, optimized checkout flows, and CRO-focused UX

  • Manage multichannel marketplace operations (Amazon, Lazada, Shopee, Carousell) — listings, inventory sync, pricing strategy

  • Execute technical SEO strategy: schema markup, Core Web Vitals optimization, technical audits

  • Implement human-in-the-loop approval pipelines for AI-driven business processes handling sensitive operational data


Required Qualifications



  • Minimum 4 years professional full-stack development experience

  • Demonstrated production experience building multi-agent AI workflows (n8n or equivalent) — not just prompting LLMs, but designing branching automation logic with API orchestration

  • Strong hands-on expertise in enterprise SQL database design and performance tuning (not just CRUD queries — schema design, indexing, stored procedures)

  • Proven Docker/VPS/Linux administration experience in live production environments

  • WordPress/WooCommerce development at scale (50+ page sites, custom Elementor systems)

  • Direct experience managing e-commerce marketplace operations across at least two of: Amazon, Lazada, Shopee

  • Portfolio/references demonstrating end-to-end ownership of at least one deployed AI automation system

  • Bachelor's or Master's in Computer Applications, Computer Science, or related field


Preferred


  • Experience with government/enterprise client environments requiring compliance-grade documentation
