📍 Noida · 5 days WFO 🕐 Full-Time Internship · 6 months · Immediate Joiners
₹25,000/month stipend ·
LET'S SKIP THE PART EVERY OTHER FINANCE JD DOES
Most finance internships give you a filing cabinet, a half-read manual, and a spreadsheet nobody looks at. We're not going to do that.
Here's what this actually is: for six months, you become part of the team that keeps a global B2B SaaS business billing cleanly across time zones. You'll process invoices for enterprise customers whose names you've seen on magazine covers. You'll learn subscription-revenue mechanics from the finance operators who run them live. You'll leave with the kind of résumé line that makes recruiters stop and read.
It's the kind of finance craft you can't learn from a textbook. Most people in India wait three years to get this exposure. If you can do it now — read on.
THE MISSION
We aren't automating scripts — we're deprecating the era of manual-heavy testing entirely. TestMu AI is building the world's first AI-native platform where Agentic Intelligence autonomously plans, authors, and self-heals the entire Quality Engineering lifecycle.
The name "TestMu" comes from our community conference — our users and our team are the heartbeat of what we build, not an audience.
Every great engineering product sits on top of a finance engine that bills cleanly, collects reliably, and reports accurately. That engine is where you'll be. Fortune 500 customers, subscription billing at scale, and the live rebrand from LambdaTest to TestMu AI happening around you.
WHAT YOU'LL WALK AWAY WITH
Six months from now, here's what will be true about you.
- You'll have sent hundreds of real invoices to procurement teams at Fortune 500 companies. Not a case study. Receipts.
- You'll have reconciled hundreds of payments against open AR — the detective work that teaches you how money actually moves in a B2B SaaS business.
- You'll be fluent in the modern billing stack:, Stripe exposure. The kind of tool literacy most people pay a Big Four firm three years to teach them.
- You'll understand subscription revenue, ARR, MRR, deferred revenue, churn, expansion mechanics the way an operator understands them — not the way an MBA textbook sketches them.
- You'll be able to walk into any SaaS company in India and name exactly what a modern billing operations team does, how, and with which tools. That's a hireable skillset.
WHAT YOU'LL OWN
This is real work. Not shadowing.
- Your own set of customer accounts — invoicing, payment tracking, and subscription management for a defined segment from week two onwards.
- Payment reconciliation — matching bank entries to open invoices, investigating variances, closing the loop. The puzzle work that makes finance clean.
- Follow-ups with procurement teams in the US — in your own words, on your own cadence. We'll teach you the register; you'll own the voice.
- Weekly reporting: AR ageing, billing variance, open subscription items. What you report shapes what finance leadership decides on next.
HOW YOU'LL SPEND YOUR WEEK
So you know what you're walking into.
- Start of shift: triage the AR movement from the previous day. Spot the exceptions. Prioritise what needs to go out today.
- Reconciliation blocks: matching bank statements against open invoices, chasing variances, closing the loop with sales and procurement.
- Live communication: emails to US procurement teams, Slack with Sales and Customer Success, async updates to the finance team globally.
- Weekly team sync: AR ageing review, billing variance deep-dive, action items you'll own for the week.
- Learning blocks: shadowing the FP&A team on month-end close, understanding how your work rolls up into ARR / MRR dashboards and finance leadership reporting.
Honest note on shift: this role runs on US hours (approximately 6 PM – 3 AM IST window, rotational). You'll cover US business hours because that's when our customers' procurement teams are live. We cover cabs, lunch, dinner, 24/7 snacks, in-house mental health coach, and rest rooms. If you want a 9-to-5, this isn't it.
HOW WE'LL KNOW YOU'RE GREAT
What we're actually looking for.
- Attention to detail. You catch the mismatched decimal before it becomes a $20K problem. Numbers don't blur in front of you — they resolve.
- Numerical intuition. A reconciliation isn't a chore for you; it's a puzzle. You'd rather figure out why 847 doesn't equal 850 than move on and ignore it.
- Communication clarity. You can email a Fortune 500 procurement lead at 11 PM and sound like a professional — not a student. Writing isn't a soft skill in this role; it's the job.
- Extreme Ownership: Takes full accountability for outcomes, not just tasks.
WHAT'S IN IT FOR YOU
Real signals, not marketing.
- ₹25,000/month stipend — no unpaid work, no "exposure economy."
- A clear ladder: Intern → Billing Associate → Senior Billing Associate → Finance Analyst → FP&A. We hire for the trajectory, not just the role.
- Direct exposure to Fortune 500 finance teams and procurement cycles — rare at the intern level anywhere in India.
- Hands-on fluency in the modern B2B SaaS billing stack: Stripe, exposure. Tools that take Big Four firms years to teach.
- Cabs across Noida & Delhi NCR. Fresh lunch and dinner every day. 24/7 snacks. In-house mental health coach. Rest rooms when you need to reset.
- A team that treats interns as team members — not free labour.
WHO THIS IS FOR
- Final-year students or recent graduates — B.Com, M.Com, MBA (Finance), CA Inter, or related commerce background.
- Strong Excel. Not "familiar with." Comfortable with VLOOKUP, INDEX-MATCH, pivot tables, and nested conditionals under time pressure.
- Comfortable with rotational US night shift (6 PM – 3 AM IST window). This isn't negotiable — our customers are in the US.
- Immediate joiners or candidates within 15 days of graduation.
- 5 days from the Noida office. This is not a remote role.
- You see finance operations as a career foundation — not something to try for six months while you figure out what you want to do. We can tell the difference.
YOUR PATH
Intern → Billing Associate → Senior Billing Associate → Finance Analyst → FP&A.
Your growth at TestMu AI is mapped to what you ship — not how long you've been here. Prove you can own a customer segment cleanly in the internship, convert to a full-time Billing Associate. Prove you can mentor the next intern cohort, move to Senior. Prove you can read the AR aging report and drive finance leadership decisions off it, move to Analyst. This is the ladder, and it's real.
