Who We Are

At Intropic, we’re building the future of financial intelligence, where deep market expertise meets the power of AI. Founded in London’s financial centre of Canary Wharf, we exist to transform complex data into clarity, precision, and action. Our culture is shaped by truth-seeking, velocity, and ownership, values that drive how we build, learn, and collaborate every day. We move fast, think independently, and hold ourselves to the highest standards of integrity and impact. Here, curiosity isn’t just encouraged, it’s essential. If you’re driven by challenge, inspired by innovation, and ready to amplify your intelligence alongside a team of exceptional thinkers, Intropic is where your ideas can truly compound.

Who We Look For

• Designing, building, and maintaining scalable backend services with a strong focus on cloud architecture.
• Writing clean, well-tested, and production-ready Python code (with opportunities to use Go or Rust where appropriate).
• Deploying and operating production systems on AWS with an emphasis on reliability, security, and performance.
• Using Infrastructure as Code to provision and manage cloud resources.

Requirements

• Strong communication skills with both technical and non-technical stakeholders.
• Independent and self-driven learner with a strong interest in containerised backend engineering.
• Strong Python experience
• Experience with Cloud-Native system design and hosting
• Experience with debugging via observability and monitoring tools such as Prometheus and Loki.

Desirables

• Experience or interest in Go and/or Rust.
• Experience with graph databases or knowledge graphs (e.g. Neptune, Neo4j, or graph modelling on Postgres).
