Senior Software Engineer at Simplesat — Bangkok, Thailand

About The Role

🧡 Why you might love this role

Work on a  real product  used daily by real customers around the world
Own features end-to-end  with AI agents (hi, Claude Code 👋) — schema, APIs, UI, tests, the whole nest 🪹
Help shape  how  we build with AI, not just “take tickets”
Turn the agent's recurring oopsies into reusable tooling, so the same mistake never bites us twice
Join a  small, friendly, slightly weird team  where your ideas actually matter

🧠 Why Simplesat is interesting (for engineers)

Build where it matters  — the core product powering surveys, responses, analytics, and dashboards customers rely on every day
Grow through real scale  — real-time surveys for  millions of responses , with instant syncing, reliable global delivery, and dashboards that stay fast and clear
Learn from complexity  —  75+ integrations , each one teaching you something about data flow, failure modes, and resilience
Play on the AI frontier  — we're actively reshaping how we build with AI, and you'll have outsized influence on what “good” looks like here
Build for the future  — clean, scalable architecture so we keep shipping quickly without painting ourselves into a corner

🧩 What you'll be doing

Designing & building features end-to-end  across our stack, directing AI agents to produce a PR you'd happily merge
Making AI output trustworthy  with unit + E2E automation and self-validating loops, so the team approves with confidence instead of squinting at every line
Refactoring toward simplicity  — retiring dead code, collapsing duplicate patterns, keeping things legible for both humans and AI
Making sharp technical calls  on architecture, performance, and trade-offs, and knowing which doors only open one way
Sharing knowledge and raising the bar  with your teammates

🌈 What we value in engineers

Judgment over keystrokes  — knowing what's right to ship, not just how to make it run
Calibrated trust in AI  — you use it hard, and you know exactly where  not  to
Ownership  over the tasks and projects you commit to
Autonomy with accountability  — you don't need hand-holding, but you keep the team in the loop
Curiosity and continuous learning , with a bit of  healthy weirdness

🛠 Our current toy box
AI-assisted tooling (Claude Code) • React • Python • Django Web APIs • PostgreSQL • Redis • AWS • OAuth • Webhooks • GitHub • Notion • Slack • Figma
This is  not  a strict checklist. Curiosity and learning speed matter more than ticking every box.
🎯 A bit about you

Based in  Bangkok  and comfortable in  English  (spoken + written)
5+ years  building and shipping web applications, strong  JavaScript  and modern web fundamentals
AI is already how you build  — you've shipped real production work this way, not just experimented
You  validate by testing, not by trusting  — unit and frontend E2E automation are part of how you deliver
A real  refactoring  track record, reducing complexity in a live, messy codebase
Comfortable building and consuming  REST APIs , and you've written optimized SQL and handled concurrent writes in higher-traffic systems
You can collaborate with product and design and explain your trade-offs without drama

Experience designing reusable AI context, skills, or guardrails for a team is a lovely bonus.

And tell us one quick story: a time an AI agent failed you on real work — what broke, and what you changed so it never happened again. That tells us more than any CV ever could.
