Resumen del rol

Contenido del rol extraído en secciones para revisar más rápido.

Driving the technical direction of the frontend application stack — architecture, standards, and the trade-offs that keep the platform fast and maintainable
Hands-on TypeScript and Rust — building and reviewing the most critical or complex work yourself
Real-time, data-dense trading interfaces across FX, Equities, and Cryptocurrency, and the application services behind them
Owning code quality across the team through review, design sessions, and the standards you set and enforce
Developing the engineers on the team — technical craft and the non-coding skills that let people scale
Shaping the roadmap with the CTO, CDO, Technical Delivery, and Client facing teams, and turning priorities into delivered software
Ensuring the team owns its Level 3 support, observability, and operational readiness — reliability is not optional

Strong full-stack engineering background with deep TypeScript / JavaScript (ES6+) (5+ years, including time leading or setting technical direction for a team)
Familiarity with React and reactive state management (RX, MobX, or similar)
Working knowledge of Rust, or the clear appetite and ability to get there — it's part of our stack
Solid grasp of distributed systems, API design, and real-time data (REST, WebSockets, network protocols) — you understand what it takes to build software that's fast and reliable under load
Able to make and defend architectural decisions, and explain the trade-offs to engineers and non-technical stakeholders alike
Experience in financial services or trading technology

You lead by example. You write code, review designs, and hold the highest standards. Engineers respect a lead who understands the work, not one who manages it from a distance
You build strength across the team. You know when to be hands-on and when to step back. You lead with depth and raise the others up, rather than being the single point of failure
You own it. You take responsibility for the team's delivery, quality, and production reliability — not just your own output. When something breaks, you lead the investigation and fix
You develop people. You invest time in mentoring and growing the team, and you can point to engineers who are better for having worked with you
You're direct and honest. You give specific, timely feedback, and you hold a quality line without becoming a bottleneck
You communicate. We're a distributed team across multiple time zones. Clear, proactive communication — especially during incidents and in stakeholder updates — is essential
You embrace AI tooling. We use AI tools (Claude, Gemini) to amplify our engineering capability — from code review and debugging to incident investigation and documentation

Real problems —trading systems where performance is measured in microseconds, not user clicks
An excellent team — senior engineers who care about craft, collaborate openly, and hold each other to high standards
Ownership — small teams, clear accountability, direct impact on the platform and our clients
Competitive package — up to 30 days leave + bank holidays, private health insurance, pension, life insurance, dental/optical cashback, cycle to work, socials and offsites
Remote-friendly — work from home with flexibility. We trust our people to deliver
Sustainable pace — we work hard, but we don't burn people out. Balance is how we stay sharp
Growth — career progression to senior roles, performance specialisation, or technical leadership. We invest in people who invest in us
