We’re partnering with a deeply technical, fast-moving fintech firm building systems that process and visualise vast amounts of real-time data. They’re looking for a Full-Stack Engineer to help design and deliver next-gen tools that sit at the intersection of data, systems, and human insight.
If you love clean code, sleek interfaces, and the challenge of scale, this one’s for you.
What You’ll Be Doing:
- Developing sophisticated front-ends using React and D3.js for high-frequency data streams
- Designing back-end APIs and services focused on performance and reliability
- Crafting responsive visual tools that empower decision-making in real time
- Writing high-efficiency components in Rust
- Collaborating closely with cross-functional teams: engineering, product, and domain experts
What You’ll Bring:
- 5 years of strong experience with modern JavaScript/TypeScript, especially React
- Deep knowledge of data visualisation (D3.js or similar frameworks)
- Comfort with building back-end services (Node.js, Rust, or related technologies)
- Familiarity with real-time architectures, WebSockets, or low-latency systems
- A strong eye for detail and performance — you think in milliseconds and pixels
Why You’ll Love It:
- Work in an environment where engineering drives the product
- Tackle meaningful technical challenges with a direct link to real-world impact
- Enjoy exceptional compensation, top-tier health benefits, and a collaborative culture
- Join a tight-knit team that values precision, experimentation, and quality craftsmanship
Not your average full-stack role — this is where software meets performance and real-world impact at scale. If that excites you, let’s talk.
