About the role

Key responsibilities & impact

Founding Team Ownership: Designing, building, and maintaining robust, scalable services by joining our founding team of 4 engineers. Working directly with the founders without corporate red tape, you won’t just pull tickets from a backlog - you will actually own your work end-to-end, see your code ship, and see its immediate impact on users.
Building the Engineering Culture: Joining our founding engineering team means you are actively building our engineering culture, not just stepping into one. You will have a direct voice in shaping how we collaborate day-to-day, how we learn from each other, and how we preserve a friendly, agile, and tight-knit environment as we grow.
Full-Stack Versatility & Growth: Hands-on Building: Writing high-quality, secure code for our FCA-regulated platform. You’ll navigate our stack to ship features that delight users. Driven by our fast-paced environment, you will have the opportunity to step outside your comfort zone and get hands-on with the wider technical stack, levelling up your skills significantly faster than in a traditional, highly specialised role.
System Design & Architectural Contribution: Partnering directly with the engineering team to tackle complex systems design and actively shape our evolving architecture. Your technical perspective will give you a strong voice in our high-level design choices. You will have true design ownership over the specific services and components you build, ensuring they remain robust, secure, and performant as we scale.
Technical Excellence: Maintaining a high bar for code quality, testing, and documentation. You’ll participate in (and contribute to) meaningful code reviews.
System Integrity: Monitoring and improving system reliability, ensuring our trading platform is always "always-on."
Production Support: Root-causing real-time production issues; we all take pride in the stability of what we ship.

Requirements

What you’ll need

Experience: +3 years of commercial software engineering experience, ideally with experience building or maintaining distributed systems or backend APIs.
Hands-on Coder: You are a strong practitioner who loves shipping clean, readable code and takes pride in seeing features go live.
Tech Stack Proficiency: Proficient in at least one modern language (e.g., Python, TypeScript, Java, Go) and comfortable working within cloud environments (AWS, Azure, or GCP).
Pragmatic Mindset: You understand the balance between elegant code and delivering real value to users in a fast-moving startup environment.
Curious & First-Principles Thinker: You enjoy dissecting how systems work under the hood and are ready to quickly pick up domain concepts like options pricing, execution mechanics, and financial regulations.
