Must-have

• Proven track record diagnosing and fixing real placement issues at scale
• Experience sending to cold audiences
• Technical fluency with postmaster tools across major mailbox providers
• Deep expertise across major ESPs
• Excellent English, C1 or above
   

Nice to have

• Direct newsletter experience with promotional content at scale

• Existing relationships with deliverability teams at major ESPs and mailbox providers
• Background in performance marketing, affiliate, or media
   

Compensation and benefits

• Competitive salary + bonuses
