Part Time Senior Customer Success Jobs (NOW HIRING)

Be the Voice That Keeps Our Customers Coming Back

Why This Role Matters
When a new customer signs on with Filtrous, the sale is just the beginning. The real value is built in what happens next: a smooth onboarding, proactive check-ins, and a partner who genuinely understands their lab's needs. As our Customer Success Representative, you'll own the post-sale relationship from onboarding through renewal and expansion. You'll be the reason customers stay, grow, and tell their colleagues about us. In a market where switching suppliers is easy, your work makes Filtrous the partner labs choose to keep.

What You'll Do
Onboard Every New Customer for Success: Guide new accounts through a structured onboarding process within 3045 days, setting clear goals and ensuring they reach value fast. You'll facilitate seamless handoffs from Sales so momentum is never lost.
Own Retention and Drive Growth: Maintain a 90%+ retention rate across your portfolio. Lead renewal conversations, identify expansion opportunities, and proactively engage at-risk accounts before problems become cancellations.
Monitor Customer Health: Track satisfaction scores and customer health metrics weekly using CRM and CSM tools. Spot risks early, escalate when needed, and ensure every account gets the attention it deserves.
Turn Happy Customers into Advocates: Generate case studies, testimonials, and referrals from satisfied customers each quarter. Collect and relay product feedback to Sales, Marketing, and Product teams to close the loop.
Manage Accounts Receivable: Track past due customer accounts and follow up to maintain healthy cash flow. Coordinate with internal teams to resolve outstanding balances and keep customers in good standing.
Place Orders for Customers: Process orders directly when customers request assistance with their purchases. Ensure accurate order entry, confirm product details, and coordinate timing with the operations team.
Make Service Calls: Conduct proactive outbound calls to check in with customers, surface needs, resolve issues before they escalate, and uncover opportunities to deepen the relationship.

Problems You Will Solve
No One Owns Customers After the Sale: Today the relationship ends when the deal closes, so hard-won customers can quietly drift to a competitor in a market where switching suppliers is easy.
Rocky First Few Weeks: New customers have no consistent path to value in their first month, so accounts can stall or sour before they ever become loyal.
Trouble Spotted Too Late: No one is watching customer happiness week to week, so unhappy accounts surface only when they are already canceling instead of while the problem is still fixable.
Overdue Bills Tie Up Cash: Past-due accounts go unchased, locking up money the business needs and letting balances pile up with no one following through to collect.
Happy Customers Go Untapped: Satisfied customers are never asked for reviews, referrals, or feedback, so the company misses easy growth and never hears what to improve.

How Success is Measured
Achieve 90%+ satisfaction rating on new customer onboarding within 3045 days
Maintain 90%+ retention rate across assigned accounts
Reduce churn in at-risk accounts by 90% through proactive engagement and issue resolution
Generate case studies, testimonials, or referrals from happy customers each quarter
