Job Description

At Pencil, we are driving innovation in advertising technology through our state-of-the-art SaaS product, which harnesses Generative AI to redefine content creation. Our mission is to make AI the default in advertising without replacing creative people. To achieve this, we need to make sure that our technology isn’t just in the hands of big brands - we need to try to help small businesses and creative individuals too.

We're looking for a Security & Trust Specialist to join Pencil at a pivotal moment of growth. This is a hands-on, technical role for someone with a background in desktop support, IT systems administration or a similar technical operations role who is now building a career in security. You'll own the day-to-day security operations that keep Pencil safe — endpoints, identity and access, cloud and SaaS security — and you're happy to lend a hand with practical IT and device issues where needed. You'll work directly with our Head of Security & Trust, who will support your growth into the audit, compliance and vendor-risk side of the role over time.

Deep Dive About Pencil

Pencil uses AI to make ads. Our mission is to make marketing effective and effortless. We want to become the default way ads get made - because AI ads are 10x faster and cheaper to make, and 2x better performing, than making them without AI.

We’re called Pencil because we believe AI will be a tool for creative people, not a replacement - it may even be as fundamental a tool in the future as the pencil was in the past.

Pencil was founded in 2018 with a team from Google, Facebook and Uber with backing from Sequoia and Entrepreneur First. We were acquired by The Brandtech Group in 2023 to pursue a shared vision of bringing GenAI to the Fortune 500.
