Proof of Human (YC S23) Hires Technical Staff Member
31 Aug 2026
Proof of Human, a Y Combinator-backed startup founded in 2023, is hiring a Member of Technical Staff — a hybrid research-and-engineering role central to its mission of building what the company calls "the proof-of-human layer in digital identity."
What the role entails
Proof of Human describes itself as a research and deployment company focused on frictionless, continual human verification. The company is seeking an exceptional engineer to work across full-stack web development and research, with backend infrastructure designed to handle millions of sessions per minute at minimal latency.
The ideal candidate has 3 or more years of software development experience. Notably, the role may also involve co-authoring scientific articles for venues such as Science, NeurIPS, and ICML — signaling that this is not a purely product-engineering position but one that blends applied research with shipping code.
Company background
Proof of Human was founded in 2023 by Mayank Agrawal and Matt Hardy, both Princeton PhD scientists. The company is backed by Y Combinator and Brickyard Ventures, though no details on funding amounts have been disclosed.
The founders' academic pedigree, combined with the research-publication component of this hire, points to a research-driven technical culture — one where scientific rigor is treated as a product differentiator rather than a side project.
What's missing
Several key details remain undisclosed. There's no salary, equity, or compensation information attached to the listing, and no confirmation of whether the role is remote, hybrid, or in-person. The company also hasn't shared team size, current headcount, or broader company-stage context, nor the specific amount raised from its YC and Brickyard Ventures backing.
Why founders should care
For early-stage founders, this listing is a useful signal rather than a definitive data point. The emphasis on infrastructure capable of handling millions of sessions per minute suggests Proof of Human may be anticipating — or already seeing — meaningful verification volume, which could hint at early product traction. The dual research-engineering scope of the role also indicates the company is likely trying to scale technical output and scientific credibility in parallel, a strategy that resource-constrained startups don't always attempt simultaneously.
Backing from Y Combinator and Brickyard Ventures likely means the company has cleared some baseline investor vetting, though without disclosed funding figures, it's hard to gauge runway or scale with confidence. Founders building in adjacent spaces — identity verification, trust and safety, or applied AI research — may want to watch how Proof of Human structures this kind of hybrid role, as it could reflect a broader hiring pattern among research-heavy, YC-backed startups: combining engineering execution with publishable research output to build both product and reputation at once.
The lack of compensation transparency is worth noting as a risk for prospective candidates evaluating the opportunity, and it limits how well outside observers — including competing founders — can benchmark this hire against market norms.
