You lead through influence, not authority. You enjoy digging into complex systems, asking the hard questions, and leaving things better than you found them. Ambiguity doesn't faze you. High standards do matter to you. You balance humility with conviction, think beyond the next sprint, and care about building things that are genuinely reliable and valuable to the people using them. Why Ocho? We represent the largest selection of technology roles of any recruitment firm in Northern Ireland. If this one isn't quite right, we're always up for a coffee to talk through where you want to go in 2026.
