We are looking for a Software Engineer to design, develop, and deliver software features and services, while building a solid foundation in the reliability, scalability, and operational health of the systems we run. This role blends hands-on software engineering with site reliability engineering: you’ll build features and systems, learn how they behave in production, help respond when things break, and contribute to making them more resilient. You’ll work across the full software development life cycle (SDLC), from requirements and design through testing, deployment, and operations. You’ll own well-defined pieces of work end-to-end and grow toward leading larger technical decisions with support from senior engineers.
In this role, you will get to:
Write clean, well-structured, and testable code, with attention to performance, scalability, and maintainability
Participate actively in code reviews, giving and receiving constructive feedback that helps keep code quality high
Build and improve services with reliability in mind, including adding monitoring and alerting and contributing to incident response
Develop and maintain microservices and distributed systems, learning to reason about service boundaries, data consistency, and failure handling
Contribute to infrastructure and deployment work for the systems you build, including cloud services, CI/CD pipelines, and (ideally) infrastructure as code
Take part in on-call rotations and production incident investigations, and help implement root-cause fixes with guidance from senior engineers
Work with senior engineers and stakeholders to turn business requirements into well-scoped technical tasks
Develop features and solutions using our tech stack, and contribute ideas on tools and approaches
Debug and troubleshoot issues across the stack, escalating when appropriate
Communicate progress, risks, and blockers clearly, and deliver your work on agreed timelines
Contribute to improving the SDLC and internal engineering processes
Share knowledge with teammates and support newer or junior engineers where you can
You’ll be successful if you have:
Bachelor’s degree in Computer Science, Computer Engineering, or a related field
3+ years of hands-on software development experience, including delivering features or projects from start to finish
Strong working knowledge of JavaScript and Node.js, with hands-on experience in frameworks such as Next.js, React.js, or Express
Comfortable working and scripting in a Linux environment
Working knowledge of cloud platforms such as AWS or Google Cloud
Hands-on experience with CI/CD tooling (Jenkins, GitLab CI, GitHub Actions, or similar); exposure to Infrastructure as Code (Terraform, CloudFormation, or similar) is a plus
Interest in growing into SRE practices: monitoring and observability, incident response, on-call, and postmortems
A track record of learning new tools and technologies quickly
A good understanding of SDLC principles and an interest in sound architecture and design
Thai national or currently based in Bangkok
Strong English proficiency, both spoken and written

Who we're looking for
Attitude matters as much as experience. We want someone who treats the brand like it's their own.
You'll be a great fit if you:

- Use AI tools every day and build workflows that save the team time
- Write clearly and give short, honest updates, including bad news early
- Can brief a designer and guide a teammate

- AI: use AI tools across content, copy, video, research and reporting, and set up simple automations
- Lead: own the marketing calendar and guide our Marketing Manager
- Report: a short weekly report (store sales and conversion, email/SMS revenue, list growth, Instagram growth, ad results, next tests) and a monthly review
Requirements
- 3+ years marketing a consumer product brand online (DTC / e-commerce)
- You've built email flows and campaigns yourself in Klaviyo or similar, with revenue results you can show
- Instagram growth you can show: accounts you ran, content you led, real numbers

- Heavy, daily use of AI tools (e.g. ChatGPT, Claude, Midjourney, Canva AI, CapCut) and you can show us how
- Strong written English. Working English is required.
- Comfortable with numbers: Google Sheets, Shopify and Klaviyo reports
- Reliable computer, internet and power backup
Nice to have, not required: SMS tools (Postscript, Attentive, Klaviyo SMS); Meta Ads Manager or TikTok Ads hands-on; Shopify CRO apps and A/B testing; influencer or UGC programs; supplements, health or beauty brands; knowing what health claims a supplement can and can't make.
Your future here
- Long-term role on a growing brand, working directly with the founder
- Room to grow into Head of Marketing or Growth, help hire and lead a small team, own launches and new channels
- Pay grows with your impact, with regular raise reviews
