Atrium EMEA is looking for several Senior Full‑Stack Engineer with good experience of FX e‑Trading (React/TypeScript + Java) to help architect and build a new FX e‑trading platform from the ground up, working across the stack to deliver high‑performance, resilient, and secure systems. You will partner closely with product, trading, and infrastructure teams to deliver features end‑to‑end—from UI and desktop container experiences to low‑latency backend services. Lean into the latest AI coding tools to accelerate delivery, strengthen code quality, and enhance developer experience. 4 days onsite in London. PAYE/Umbrella options.
* Lead design and development of full‑stack features: React/TypeScript web apps, desktop container integrations (OpenFin or similar), and Java services.
* Architect and implement scalable, event‑driven, and microservices‑based backend components (e.g., Spring Boot), including APIs, market data, order/risk workflows, and real‑time streaming.
* Build performant and accessible UIs with modular, reusable components; drive state management, data visualization, and UX for trading workflows.
* Optimize latency, throughput, and reliability across the stack; instrument observability (metrics, tracing, logging) and performance profiling.
* Establish engineering best practices: code standards, testing strategies (unit/integration/E2E), CI/CD, secure coding, and release management.
* Mentor engineers through code reviews, design sessions, and hands‑on pairing—encouraging thoughtful abstractions, clean architecture, and pragmatic delivery.
* Use AI development tools for assisted coding, refactoring, test generation, secure code analysis, documentation, and knowledge search—evaluating where AI accelerates while maintaining human oversight.
* Collaborate with stakeholders to translate trading requirements into robust technical designs; write clear specs and implementation plans.
Essential:
* Professional software engineering experience, with deep expertise in: Frontend: React, TypeScript, modern tooling (bundlers, linting, testing frameworks).
* Backend: Core Java, Spring Boot (or similar), multithreading/concurrency, performance tuning.
* Experience designing and operating distributed systems (microservices, event‑driven architectures, messaging/streaming).
* Strong understanding of computer science fundamentals (data structures, algorithms, concurrency, networking, OS).
* Proven experience in e‑trading or real‑time financial systems (FX highly desirable), including familiarity with market data, order flows, and execution workflows.
* Hands‑on with CI/CD, containerization, cloud/on‑prem deployments, and observability.
* Comfort evaluating and integrating AI coding tools into daily development workflows.
* Excellent communication and stakeholder engagement; able to lead initiatives and mentor others.
* Experience with desktop container frameworks (OpenFin, Electron, or similar).
* Experience with streaming/messaging (e.g., Kafka, Solace) and low‑latency patterns.
