Junior Customer Success Representative

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.
