Job description

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

We are a fin-tech start-up with a successful suite of products, now ready to build the next big thing. You must thrive working on open-ended problems across a range of disciplines; we are a start-up where our engineers do much more than just pick up JIRA tickets. A typical week may include debugging python, deploying infrastructure changes, talking to product early-adopters, and strategic planning with the team leads. We hire the person not the CV; if you’re interested, we’d love to hear from you!

Responsibilities

• Working with product managers and engineers to design and deliver full-stack features end-to-end.
• Building and maintaining backend services and APIs in Python, with opportunities to work in Go or Rust.
• Developing user-facing applications using React and TypeScript.
• Deploying and operating cloud-native applications on AWS with a focus on reliability and scalability.
• Maintaining, monitoring, and improving production systems and development workflows.

Requirements

• Strong communication skills with both technical and non-technical stakeholders.
• Experience building backend services in Python; interest or experience with Go and/or Rust is a plus.
• Experience developing modern frontend applications with React and TypeScript.
• Hands-on experience with AWS cloud deployments and basic infrastructure concepts.
• Familiarity with modern software development practices: Git, CI/CD, automated testing, and Docker.
