A non-technical founder hiring their first engineers is being asked to judge something they cannot evaluate directly, and most respond in one of two unhelpful ways. Some outsource the judgement entirely to a recruiter, whose incentive is placement rather than fit. Others try to compensate by learning enough to run a technical interview, which produces a superficial screen that a well-prepared weak candidate passes and a strong quiet one fails. Neither works, and the way out is to stop trying to assess what you cannot.
Borrow the technical judgement instead. A trusted senior engineer, hired for a few hours to run technical assessment on your candidates, is the highest-return money you will spend at this stage. Not a friend doing you a favour between meetings — someone engaged properly, briefed on what the role needs, and asked for a written assessment. If you have no such person in your network, that is itself an argument for a fractional technical advisor before the first hire rather than after it.
What you can assess yourself is substantial and predictive. Can they explain something technical to you clearly, at your level, without either condescension or hiding behind vocabulary? That skill correlates strongly with the ability to work with non-technical colleagues, and its absence is a reliable predictor of friction later. Ask them to walk you through a decision they made and regretted. The quality of that answer — whether they can identify what they got wrong and why — tells you more about how they will behave in your company than any assessment of their code.
A paid trial project beats an interview loop for a first hire, and most good candidates will accept one if it is genuinely paid and genuinely bounded. A week of real work on a real problem shows you communication, estimation accuracy, how they behave when something is ambiguous, and whether they ask questions or guess. It also shows them what working with you is like, which matters, because your first engineer is choosing you as much as the reverse.
Be careful about the first hire's seniority. A junior engineer with nobody to learn from will not develop and will make decisions above their experience level. The first hire should be someone who has worked in a well-run team before and knows what one looks like, because they will set the practices everyone after them inherits. Paying more for that person and hiring the second one later is almost always the better trade, even though it feels slower.
Finally, be honest in the process about what you are and are not. Founders sometimes overstate technical understanding to seem credible to candidates. Strong engineers see through it immediately and it costs you the ones you most want. Saying plainly that you do not have the technical depth and are building a team to supply it is not a weakness in that conversation — it is the accurate description of a real opportunity, and the right person hears it that way.
