About this position

Experiment, automate, monitor, and repeat. That's how we've built the world's highest performance sales email delivery network with a tiny talented team.

You'll work closely with Leandro (Principal Engineer) and Cesar (Head of Operations) to creatively scale our networks to meet customer demand.

You like working with sharp, creative people, and look forward to growing a team under you soon.

Why you should join Lightmeter

Lightmeter is SendGrid for salespeople - the first email delivery network just for sales. It integrates with sales apps like HubSpot and Salesforce, and gets outbound email into inboxes, instead of going to spam.

We built an Open Source mailserver automation system, and peer network for exchanging data to help independent mailservers deliver. Our last company was an Open Source Mailchimp, sending billions of emails each month.

Email connects startups to 85% of adults worldwide - sales over email makes innovation possible, and builds unicorns. We use email's Open Standards and our own Open Source to get new ideas in front of the relevant buyers.
