About HiddenLayer
What is HiddenLayer?
HiddenLayer is an AI security company. Its homepage says "The HiddenLayer AI Security Platform secures agentic, generative, and predictive AI applications across the entire lifecycle, protecting IP, ensuring compliance, and enabling safe adoption at enterprise scale." The platform has four modules: AI Discovery, AI Supply Chain Security, AI Attack Simulation and AI Runtime Security. A 2023 press release says "Founded in March of 2022 by experienced security and ML professionals, HiddenLayer is based in Austin, Texas." The about page lists Christopher "Tito" Sestito as Chairman of the Board, CEO & Co-Founder, with Tanner Burns as Co-Founder & Chief Scientist and Jim Ballard as Co-founder & COO. On 2 September 2026 the company announced a $100 million Series B led by Delta-v Capital, after a $50 million Series A announced on 19 September 2023. The Series B release says HiddenLayer "signed more than 50 new platform customers, including some of the largest names in securities brokerage, banking, insurance, accounting, government, technology, IT services, pharmaceuticals, airlines, and the US defense and intelligence communities."
Where will I work?
HiddenLayer's job adverts describe a remote company: "Fully Remote: We are a completely remote global team. Though we’re distributed, we are intentional about getting the team together a couple of times a year." The three Lisbon adverts end that sentence at "getting the team together". On 12 November 2026 its Greenhouse board listed 20 adverts, and Greenhouse tags all 20 with the office "Remote". Fifteen are located in the United States (nationwide, or tied to a region such as the Bay Area, New York City, Denver, Seattle or Portland, Southern California, the Southeast or the DC Metro Area), two are UK roles listed as "Remote- UK" and three are in Lisbon, Portugal. The Lisbon adverts are less uniform: the Software Engineer advert calls itself "a fully remote, full-time role", the Technical Engineering Lead advert says "Based in Lisbon", and the Technical Product Manager advert is headed "Lisbon, Portugal- In person" while still carrying the fully remote benefits line. The company blog says "twice a year, we gather in person for company offsites". No page publishes an office street address; the privacy notice gives a postal address in Austin, Texas.
What is the HiddenLayer team like?
The open roles on 12 November 2026 are mostly in sales: 16 of the 20 adverts (Enterprise Account Directors by region, AI Solutions Architects, channel roles, a VP of Sales and a VP of Sales Engineering). Three are in engineering (a Platform Engineer in the US and two Lisbon roles, including a Technical Engineering Lead for "the Portugal-based R&D team") and one is a Technical Product Manager in Lisbon. Three adverts are federal-market roles with a DC Metro Area location preference: the Director of Federal Sales advert says "Active TS clearance required; TS/SCI highly desired." and the AI Solutions Architect- Federal advert says "Active Top Secret or TS eligible strongly preferred". The careers page says "HiddenLayer is growing rapidly, and we’re seeking innovators, defenders, and researchers who want to make a meaningful impact." The company's own post "Life at HiddenLayer" (30 May 2025) says in its first paragraph "As a remote-first company focused on securing machine learning systems" and warns that "If you need detailed direction and structure every step of the way, HiddenLayer might feel like a tough environment."
Work-Life Balance
All 20 adverts, across Sales, Engineering and Product Management, carry a time-off line. In the 17 US and UK adverts it reads "Flexible Time Off: Enjoy unlimited and flexible time off for all salaried employees, in addition to 15 paid company holidays." and the three Lisbon adverts end "in addition to paid company holidays" with no number. The careers page itself does not state a time-off policy, and no number of days is given anywhere. The "Life at HiddenLayer" post says "We trust you to take the time you need to rest, recharge, and take care of life." and "The remote-first structure means your day can flex to fit your life, not the other way around." It also says "We don’t measure success by how many hours you sit at your desk. We care about outcomes." No page or advert states weekly hours or core hours. Travel is mentioned for some sales roles, for example "Travel approximately 10–25%" in the Director of Federal Sales advert.
