SellCord is a leading agency specializing in launching and scaling brands exclusively on Walmart Marketplace. As Walmart-approved partners, we help businesses grow by optimizing their presence on the platform and driving sustainable success.

This will be our first engineering hire based in China. We’re looking for a highly autonomous Senior Full-Stack Software Engineer to partner directly with our CTO and act as the technical bridge between our China operations and our global team.

As a Senior Full-Stack Software Engineer at SellCord, you’ll own the full development lifecycle for our SaaS platform and internal content workflows, from solution design through delivery. This is an individual contributor role, not a management one: you’ll operate like a “one-person engineering team,” bringing strong technical execution together with commercial and product thinking to turn business needs into scalable solutions.

Roles and Responsibilities

• Develop and optimize features while improving internal content workflows through automation.

• Design, organise, cleanse, and maintain business data to ensure data accuracy, consistency, and usability.

• Build and optimize front-end user experiences.

• Partner with the CTO and overseas engineering teams on product planning, technical design reviews, sprint execution, and agile delivery.

• Leverage knowledge of Amazon and Walmart seller operations to identify product improvement opportunities and propose practical technical solutions.

• Utilize AI development tools (such as GitHub Copilot, etc.) to improve engineering productivity and build internal AI-enabled tools where appropriate.

• 5+ years of full-time professional software engineering experience, ideally across companies of different sizes (start-up, growth-stage, and larger enterprise).

• Strong full-stack skills: React on the front end, Python Django on the back end, and PostgreSQL; AWS experience preferred.

• Hands-on experience building tools or platforms for Amazon or Walmart sellers.

• Fluent English, comfortable participating in technical discussions, sprint ceremonies, and video meetings.

• Practical experience with AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude Code) and/or building with LLM APIs.

• Solid, hands-on experience with Agile methodologies (Scrum, Kanban, or similar) in a fast-paced delivery environment.

• Strong commercial and product mindset with the ablity to understand the business objectives behind requirements and proactively propose better technical solutions.
  
  

• Be part of a dynamic and supportive team in a fast-growing company.

• Enjoy opportunities for professional development and career growth.

• Competitive compensation with vacation days, local holidays, and sick leave.

• Work with cross-functional teams dedicated to innovation and operational excellence.
