Team: Customer Success | Reports to: CS Lead Location: Fully remote, globally distributed Level: Entry-level / early-career
About Mission Inbox
We are a B2B email infrastructure platform built for businesses that treat deliverability as a competitive advantage. More than 80 million emails leave our servers every month, and that number keeps climbing.
We are early-stage but cash-flow positive and profitable. That means you get the energy and ownership of a startup without the survival anxiety that usually comes with it. Every hire moves the needle directly. There is nowhere to hide, and that is the point.
Read This Part Carefully
This is not an easy job, and we are not going to pretend otherwise.
Customer Success is the backbone of Mission Inbox. CS is not a side function that answers tickets and forwards bugs. It is the connective tissue between our customers, our product, and our roadmap. When a customer succeeds or churns, it runs through this team first. That comes with real weight.
If you want a quiet, narrowly-scoped support role, this is the wrong listing. If you want to break into the startup world from the single best seat in the building, where you touch support, product, quality, and documentation in the same week, keep reading.
What You Will Actually Do
This role spans four areas. You will rotate through and eventually own pieces of all of them.2. Platform QA3. Product Direction4. Knowledge Base Creation
Customer Support
Be the first human a customer talks to when something is unclear, broken, or on fire
Resolve deliverability, configuration, and platform questions with speed and accuracy
Manage conversations in Intercom and turn one-off questions into reusable answers
Use the product the way customers do, then break it on purpose
Catch bugs, edge cases, and confusing flows before customers hit them
File clear, reproducible reports that engineering can act on without a back-and-forth
Sit closest to the customer, which makes you a primary input to the roadmap
Surface patterns from support conversations: what confuses people, what they ask for, what they almost churned over
Translate raw customer signal into product feedback the team can prioritize
Build and maintain the documentation, guides, and help content that scale our answers
Turn every recurring question into an article so the next customer self-serves
Treat the knowledge base as a product, not an afterthought
Who This Is For
You will thrive here if you
Are early in your career and hungry to learn fast
Like ownership and discomfort over comfort
Write clearly and think in systems
Are curious about how software actually works
Want startup experience at a company that is already profitable
The Growth Ceiling
We are not offering you an entry-level box to sit in. We are offering a launchpad.
CS is where you learn the entire business: the product, the customer, the economics, and how decisions actually get made. People who master this seat go on to run things.
For proof, look up the chain. Our own CEO started his career as a Customer Success rep and went on to build and exit companies. The seat you are applying for is the same one that taught him how a business actually works. We are not promising you the same outcome. We are telling you the ceiling is high and the path is real.
