Startup hiring is concentrated in AI infrastructure and health

The June 2026 HN 'Who is Hiring' thread and the YC job board posts paint a clear picture of where early-stage capital is going. The clusters are AI infrastructure, including inference, agent tooling, and data pipelines; healthcare AI; and defense-adjacent tech. Remote roles remain common but a notable share of the postings, particularly in Europe and NYC, are pushing for on-site or hybrid. Compensation for founding engineers is wide, ranging from $150k to over $250k at companies like SmarterDx, with equity still a major component.

The pattern here is that the demand is not for generalist software engineers. It is for people who can sit at the intersection of domain knowledge and AI implementation. Healthcare AI roles want people who understand clinical workflows. Defense roles want systems engineers who can work in constrained environments. The era of 'we need a good engineer who can figure it out' is giving way to 'we need someone who already knows this domain and can apply AI to it.'

Companies paying at the high end, like Proliferate's $200k for junior engineers, are outliers but they signal that the competition for people with the right combination of skills is intense.
