Software Engineer

At Synexus, we're helping advertisers rethink how they show up in the news ecosystem. After a successful investment round, we are now in the process of launching a new brand and product to the Ad tech market.Today, blunt keyword blocking causes brands to avoid entire news sites — even when the content is high-quality, balanced, and aligned with their values. It’s like tossing out a whole basket of fruit just because one apple has a bruise.Our technology changes that. Instead of just scanning keywords, Synexus analyzes how topics are being discussed. This allows advertisers to safely reintroduce premium journalism into their media plans — driving better reach, performance, and efficiency without added risk.At Synexus, you’ll be surrounded by people who want to improve everything and support everyone around them.
