Head of Email Infrastructure @ Explee

We are Explee. We send ~600,000 emails a day and email is our biggest cost. We are hiring one person to take the whole thing over.

Explee is an AI SDR: you give it a URL and it does the whole SDR job itself, down to writing the emails. The emails have to be hyper-targeted, so we run our own GPU cluster and scrape the entire internet to aim every message. Sending is the expensive part. Its what stands between us and cash-positive, and nobody owns it full-time today.

The numbers

The job

• Run experiments on the fleet. mailbox wear-out, 30 vs 35 sends a day, weekends, warmup schedules, IP pools. there is no manual for this, you write it
• first weeks: sort out the tests we already ran, then start on the backlog. we have ideas for months, what we do not have is anyone to run them
• the budget is yours. vendors mostly. twice already a vendor sold us cold mailboxes as "warmed" and we only caught it after paying, when the spam rates came in. now we audit every batch on delivery day
• 80% hands-on. you code
• the number you are hired to move is cost per 1,000 emails sent. the one you must not break while doing it is reply rate

Things we can not explain NEW!

1. unwarmed boxes from one vendor keep beating boxes that another vendor warmed for a whole month. we recounted it three times. it holds up, and it makes no sense
2. gmail to outlook spams less than outlook to outlook. yes, really
3. warmup does almost nothing for microsoft

something breaks or surprises us every week. you will decide what to test next.

Who fits

An ex-CTO, head of infra, or a strong team lead who still ships. The kind of person who reads the actual SMTP session instead of the vendor's dashboard. Who can also haggle. Email experience is not required.

What we offer

• $10,000 - $12,000 / month + equity
• $2M ARR, going for 20x this year, just closed a round. your metric is the P&L directly
• 9 people, everyone codes. we deploy on average every 24 minutes. our own hardware: CPU, GPU, storage (long story)
• AI runs a huge part of the business already, so the team only works on whatever is most important or most interesting
• you decide what to buy and test. there is no approval process (there is no HR department either)
• remote. full-time; starting on a contract or part-time is fine

the team. 9 people, everyone codes.

How to join

1. send email to: [email protected], subject "EHLO". plain text is fine
2. deep-dive with Vova, the guy who runs this infra today (60 min)
3. paid experiment on our fleet
4. call with Alex (CEO), 30 min
5. offer
