The Opportunity You'll own the full data stack for cybersecurity intelligence at QuoIntelligence, building and evolving the pipelines that power our Mercury platform and analyst workflows. This is a role where your architectural decisions have real, visible impact, and where you'll collaborate closely with a small, expert team of two engineers on the data side. Our platform runs on DigitalOcean with a custom-built infrastructure: ZMQ message queues, Docker containers, hand-rolled deployment pipelines, and in-house-maintained Python libraries. It was built before today's managed services existed, and it works because engineers who genuinely understood distributed systems built it from the ground up. The first major project is leading our migration to AWS, transitioning from this custom infrastructure to managed services, without disrupting production. It's the kind of challenge that requires both depth and adaptability: keeping what exists healthy while architecting what comes next. If you thrive in that kind of dual mandate, this role was designed for you. You'll Thrive Here If...



You enjoy working across the full stack rather than specializing deeply in one layer. You're energised by inheriting a well-built yet unconventional system and improving it. You're comfortable with ambiguity and find it motivating rather than frustrating. And you want your work to matter not just to a ticket queue, but to the analysts and products that rely on it every day. This is probably not the right fit if your data engineering experience is entirely on managed platforms like Databricks, Snowflake, or BigQuery, or if you're looking for a fully provisioned cloud environment from day one. The AWS migration is the destination you'll help us get there. One more thing: this is an AI-native company. Our products run on AI. We expect engineering to run on it, too. If your relationship with AI stops at asking ChatGPT to explain error messages, this isn't the right fit. What You'll Do Build an
