For people who'd rather do the work than watch it.

Why Join

Filum AI is building the AI-native platform for the customer lifecycle. This internship isn't shadowing and coffee runs - you'll carry real weight for a CS team moving fast, in the messy middle where playbooks don't exist yet. You'll see how B2B accounts actually get won, kept, and grown, up close.

• Founding-team proximity - work alongside CSMs and close to the founders, no buffer layers.
• Real work, real stakes - your output goes straight into live client accounts.
• Compounding craft - the workflows and habits you build here are the foundation of a CS career.

How It Works

• Start with training - a few structured sessions to get you up to speed on Filum, the product, and how we run CS.
• Then real exposure - you'll work on actual customer cases, shadowing a senior CSM. You won't own accounts solo yet, but you'll be in the room where the work happens, not on the sidelines.
• Grow into ownership - as you prove yourself, you take on more.

What You'll Do

Support a portfolio of B2B accounts across Retail, F&B, Real Estate, and Financial Services alongside your CSM.

• Keep accounts moving - track tasks, deadlines, and follow-ups so nothing slips.
• Turn meetings into action - clean up call notes into decisions, action items, and next steps.
• Watch the signals - help monitor account health and flag risks early.
• Prep the work - pull data, build account snapshots, and ready materials for reviews.
• Make it better - this is a heavy, fast-changing workload. We expect you to think for yourself: find smarter ways to handle it, not just grind through it.
• Learn the AI-native way - use AI skills, plug-ins, and MCPs to do more than one intern normally could.

Who You Are

Must-haves:

• At least one prior internship - client-facing, ops, or something where you owned outcomes.
• Clear communication in Vietnamese and English, written and verbal.
• Organized and proactive - you chase loose ends without being told.
• Curious and quick to learn a technical AI product.
• Bias to action - you move, then ask, rather than wait.
• Judgment - when the workload piles up, you find a better way instead of waiting for instructions.

Nice-to-haves:

• Hands-on with AI-native tools (Skills, Cowork, custom GPTs, MCPs) and eager to push further.
• Interest in SaaS, AI, or B2B software as a career direction.

This Internship Is NOT for You If

• You want a line on your CV more than the work itself.
• You want a light, predictable workload - this is heavy, and it changes fast.
• You wait to be told what to do next instead of improving how the work gets done.
• You go quiet when things get uncomfortable.
• You see ambiguity as a blocker, not a signal to move.

Logistics

• Full-time, on-site at District 2, Sala Office.
• Monthly Allowance included.
• Strong interns get first look at the full-time Customer Success Executive role.
