Who you are
- ? 5+ years of engineering experience, at least some of it in a SaaS startup or scale up
- ? You've owned a bug backlog, either for your squad, or for the entire engineering team at your previous company
- ? You debug code you didn't write, fast
- ? You think in systems and processes, not only individual tickets
- ? You've mentored or led at least 2 engineers. Management experience isn't required
- ? AI-native way of working. You already use AI daily, with good judgement and real productivity. Candidates who don't embrace AI are not a fit
- ? Fluent in Spanish and comfortable in English. We tend to speak Spanish at the office and in Slack, and write documentation and projects in English
What the job involves
- Right now, bug resolution at haddock is handled by a squad of two product engineers who rotate every month. It works, but it doesn't scale: twelve onboardings a year into the work that needs the most context, variable throughput month to month, and a backlog that goes down when we add people and back up when we take them away




- We're replacing that with a permanent Product Reliability Engineering team, and you'd be the first hire and the one who builds it. You'll lead two engineers plus a rotating seat from the product engineering team. This is a hands-on role where 75% of your time is expected to be spent doing software engineering work
- Conceptually, it's similar to a Support Engineering team, but so empowered with AI that we ambition going beyond "just fixing bugs", but actually creating the system and tooling to make haddock highly reliable and have issues quickly fixed
- Here's the part that matters most, and we want to be direct about it: your mission is not to close more tickets. It's to make the inflow shrink. A team that only drains a queue burns out. So this role comes with an explicit mandate, build solutions, automations and processes that improve the reliability of the product. That's the deal
- The technical escalation layer. Triage
