Adora AI | Senior Backend Engineer | Full-time | Seattle, WA | ONSITE At Adora, we're fixing performance marketing – an industry where brands get stuck with opaque algorithms that optimize for everyone except them.
Members of our team spent years at the big platforms and ad networks, and we know exactly how broken it is. Now we're building something better – a platform that finally puts brands in control with AI that works for them, not against them.
We recently raised our seed round led by Village Global (backed by Reid Hoffman, Jeff Bezos, Mark Zuckerberg). Real customers are already using our product and seeing results. Your work will directly impact how fast we can scale this thing.
What makes this interesting: • Daily work with cutting-edge AI tools, figuring out how to make them actually useful for marketers • Direct line to customers – you'll see your code impact real businesses immediately • Small team where your technical decisions matter and stick around
We're looking for someone who's shipped backend systems at scale and either loves the startup chaos or is ready to dive in. You'll own features end-to-end and have real autonomy over technical direction.
Python/MySQL/AWS/BigQuery is our current stack but we care more about your problem-solving approach.
If you want to work on hard technical problems with immediate business impact instead of yet another CRUD app, let's talk.
