GLINTECO

Senior Backend Engineer

Python, AI-assisted Full-stack

Full-time | Hybrid, Hanoi | 5+ years | Up to USD 1,500/month (gross)

Company Deion

We are looking for a senior backend engineer who already works with AI every day and thinks clearly enough to know when the AI is wrong.

You will own server-side work end to end: understanding the client problem, designing the data model and APIs, building and testing them, and shipping to production. When a feature needs frontend work, you will build it too, using AI tools to move fast in React or Next.js, with our frontend team reviewing UI quality.

At Glinteco, AI writes a lot of code, but people own every decision. You are responsible for every line you merge, whether you typed it or not. That means more reviewing, more questioning, and more testing, not less.

What you will do

• Design and build APIs, background jobs, and integrations in Python (Django/DRF, FastAPI)
• Model data and optimise queries in PostgreSQL
• Use AI coding tools (Claude Code, Cursor, Copilot or similar) daily for building, refactoring, testing, and debugging
• Ship small to medium frontend features in React/Next.js with AI assistance
• Break vague requirements into clear technical tasks with BAs and clients, and push back when something does not make sense
• Review code from teammates and from AI, with a sharp eye on security, data integrity, and edge cases
• Support deployments and production issues on AWS and similar platforms
• Help define how the team uses AI well: prompts, review checklists, and what we never delegate to AI

Working hours

Our core hours overlap 4 to 5 hours with Sydney business time. US clients occasionally need an evening call (9:00 New York is 20:00 Hanoi). We tell you this upfront.

Yêu cầu công việc

• 5+ years of professional backend development, with production systems you can walk us through in detail
• Strong Python, plus solid experience with Django/DRF, FastAPI, or Flask
• Strong SQL and relational data modelling (PostgreSQL preferred): schema design, indexing, query tuning, migrations on live data
• 2+ years of daily use of AI coding tools in real projects, with clear opinions on where they help and where they fail
• Has shipped frontend features (React, Next.js, or similar), with or without AI help, and can read and debug frontend code
• Git, automated testing, CI/CD, Docker
• Clear, structured thinking: you can explain a trade-off simply and defend a decision with reasons
• English good enough to read client requirements, write technical notes, and join client calls

Nice to have

• Building LLM features: RAG, tool calling, agents, evaluation
• js / TypeScript backend experience
• AWS in production (ECS, RDS, S3, Lambda or similar)
• Experience with ERP, CRM, or other business systems with complex workflows
• Has worked directly with clients in Australia, the US, or Europe

Quyền lợi được hưởng

• Salary up to USD 1,500/month (gross), based on interview results
• Flexible hours, hybrid work from our office at Discovery Complex Tower, 302 Cầu Giấy, Hanoi
• Direct work with international clients, no layers in between
• Daily hands-on work with current AI development tools
