Full Job Description

We live in a world that runs on physical industries like energy, logistics, manufacturing. These sectors are essential to our economy and daily lives, yet they are held back by inefficiencies, fragile legacy systems, and decades-old ways of working. This is not just a business problem; it is a societal one. When grids fail, supply chains stall, or factories falter, entire economies are disrupted. These companies face unique, complex challenges that typical software was never designed to solve. Cogna was founded to change this. Our mission is to give critical industries their own AI-powered Software Factory: a way to build and deploy bespoke digital tools that solve pressing operational challenges. Since our launch in May 2023, we’ve seen incredible customer traction and revenue growth. We’re backed by leading VCs, including Notion Capital and Hoxton Ventures, and we’re building a world-class team to take on one of the most important challenges of our time. Tackling challenges at this scale takes people who are curious, adaptable, and motivated by impact. If our mission resonates with you, we encourage you to apply, even if your experience doesn’t match every requirement. We are committed to building a diverse team that reflects the industries and societies we serve. Overview We’re hiring a Platform Engineer to help design, build, and maintain the foundation our teams rely on every day. You’ll join our Platform team, which supports security, core infrastructure, and DevX across Cogna. Your focus will be shaping the internal platform and cloud architecture that powers all engineering teams and underpins our product. We treat the platform as an internal product: defining APIs, abstractions, and guardrails that let teams ship quickly and safely. This role is ideal for someone who thrives on solving platform-wide challenges, enjoys working cross-functionally, and is passionate about clean, resilient cloud infrastructure. What you’ll do * Design and evolve our cloud infra
