Build it from zero, with us
We're a small senior team — based in Singapore, remote-friendly — rebuilding the antidetect browser without the legacy. If you like hard engineering problems and products that feel effortless, we'd love to talk.
How we work & what you get
Core team in Singapore — join us there, or work from anywhere.
Remote-friendly by design, with async-first collaboration across time zones.
Flexible hours — we measure output, not presence.
Top-spec equipment of your choice.
Competitive pay with early-stage upside.
A tiny senior team: own problems end to end, ship without bureaucracy.
AI Product Manager
Full-time- Define the AI side of Mango Browser: an agent that operates browser profiles for real multi-account workflows.
- Turn messy operator workflows into agent capabilities, evals, and guardrails — you decide what "reliable enough to ship" means.
- You have shipped LLM-powered products end to end, and you prototype with APIs yourself before writing a PRD.
AI Agent Engineer
Full-time- Build the agent runtime inside the browser: planning and tool-use loops, browser control, context and memory management.
- Hands-on with LLM APIs, function calling, and browser automation (CDP or similar); you know where agents break in production.
- You obsess over reliability — evals, tracing, and graceful failure over demo-ware.
LLM Algorithm Engineer
Full-time- Own model quality: fine-tuning, distillation, and evaluation for agent behaviors and human-like interaction patterns.
- Solid ML engineering fundamentals — you take models from notebook to production, and you measure before and after.
- Experience balancing quality, latency, and cost across hosted and open-weight models.
AI Infrastructure Engineer
Full-time- Build the serving and eval infrastructure behind the agent: routing across model providers, caching, observability, and cost control.
- Strong backend engineering (Go or Python) plus real experience running LLM workloads in production.
- You treat evals and tracing as first-class systems, not afterthoughts.
