Enterprise Account Executive (Founding Hire)

About Mission Inbox

Mission Inbox is a B2B email infrastructure platform processing 80M+ emails per month for 130+ customers globally; including enterprise accounts paying us $240K+ per year. We're cash-flow positive, profitable, and growing 233% YoY with 139% NRR; early-stage growth without survival anxiety.

We operate fully remote, globally distributed, at the execution standards of a company 10x our size. Our team ships three product lines we call "Cubes": Sales & Marketing email infrastructure, and Transactional email. Our AI Shield; trained on 90M+ emails; is the defensible moat in a category where deliverability gets harder every quarter.

The Role

You'll be Mission Inbox's first dedicated Enterprise Account Executive. We've proven the model; customers already pay us $60K, $120K, and $240K+ ACVs. Your job is to find more of them.

You'll build and own a focused list of 80–100 named target accounts; Fortune 1000 marketing leaders, high-growth scale-ups with serious outbound or transactional volume, and platform companies whose email is mission-critical. You'll work both our Sales & Marketing and Transactional cubes, multi-threading across CMOs, RevOps, CTOs, VPs of Engineering, and Procurement.

You report directly to the CRO. You'll partner with Marketing on 1:1 and 1:few ABM plays, and with our SMB Sales team for warm pass-ups from inbound. This isn't a lone-wolf seat — it's the lead role on a coordinated hunt.

What You'll Do

• Own a named account list of 80–100 target companies across Sales & Marketing and Transactional cubes. Build it, hunt it, defend it.
• Land $60K+ ACV deals as your baseline, with $200K+ whale hunts as your stretch.
• Multi-thread accounts — 5+ stakeholders per opportunity: Marketing Ops, RevOps, CTOs, VPs of Engineering, Procurement, Security.
• Become the email infrastructure expert in the room — speak credibly about deliverability, sender reputation, IP warming, SPF/DKIM/DMARC, and the competitive landscape.
• Run procurement — security reviews, MSAs, DPAs, vendor onboarding. You'll inherit playbooks from our existing $240K deals.
• Partner with Marketing on ABM plays for your top 20 accounts.
• Partner with SMB Sales to catch upmarket signals from inbound.
• Shape the enterprise roadmap — you'll be closer to enterprise buyer requirements than anyone, and your input goes directly to product.

Who You Are

• 4–7 years of B2B SaaS closing experience as a quota-carrying AE — not SDR background dressed up.
• Proven track record closing $80K–$250K ACV deals. This is non-negotiable. Show us deal stories, not LinkedIn taglines.
• B2B infrastructure, devtools, martech, or RevOps tech background — Twilio/SendGrid/Postmark, Outreach/Apollo/Salesloft, HubSpot/Marketo, or similar adjacent categories.
• Technically fluent — you can hold a 30-minute conversation with a CTO about APIs, authentication, IP reputation, and infrastructure without needing a Solutions Engineer on the line.
• Multi-thread by instinct — you've never won a real deal selling to only one champion.
• English fluency, written and verbal. Spanish or Portuguese is a strong plus.
• Resilient and patient on enterprise cycles — you've worked deals over multiple quarters without losing edge.
• Builder mindset — you'll co-create the enterprise playbook. No polished one exists yet.
