About the role

• Solution Architect designing core trading systems for rapidly growing global forex and CFD brokerage. Leading technical oversight and collaboration across cross-functional teams.

Responsibilities

• Lead **end-to-end solution design**, translating business requirements into comprehensive architectural blueprints encompassing system interactions, data flows, and deployment topologies, ensuring full coverage of both functional and non-functional requirements (NFRs).
• Employ an **architectural decision framework**, utilising **Architectural Decision Records (ADRs)** to document key design choices, articulating context, options considered, trade-offs evaluated, and final decisions, ensuring a traceable and reproducible decision-making process.
• Define and present **architectural views and perspectives** (Logical, Development, Process, Physical, Scenarios) tailored to different stakeholders (development teams, operations, business units, compliance), ensuring communication accuracy and effectiveness.
• Lead **architecture reviews**, ensuring designs conform to enterprise standards, security baselines, and technology strategy, while identifying potential technical risks and recommending mitigations.
• Establish and promote **design guidelines and pattern libraries**, including API design standards (REST/GraphQL/gRPC), error handling patterns, retry and circuit-breaking strategies, transaction boundary definitions, and idempotency designs, empowering development teams to consistently adhere to architectural best practices.
• Design and optimise **bridge solutions (Bridge/Gateway)** connecting **MT4/MT5** trading front-ends with internal liquidity management, risk engines, and back-office systems.
• Architect high-availability, low-latency trading gateways to ensure high performance and reliability of order processing.
• Act as a technical bridge, collaborating with the Data Architect to define how trading data flows in real-time to **Kafka** for downstream analytics.
• Partner with Security and Compliance teams to ensure system architectures meet financial regulatory requirements (e.g., data sovereignty, audit logs, transaction record retention).

Requirements

• **8+ years** of experience in software development or architecture design, with at least **3 years** in an architectural role focused on trading systems or high-concurrency financial platforms.
• CFD or FX industry experience, with a deep understanding of the trading business lifecycle: order execution, margin calculation, swaps, liquidation mechanisms, etc.
• Practical integration or architectural experience with the **MT4/MT5** platform and its ecosystem (bridges, manager plugins, API integration).
• Proficient in **architectural design methodologies**, familiar with frameworks like TOGAF or SAFe, enabling systematic architectural work.
• Experienced in **multi-perspective architectural modelling**, skilled in using UML, C4 model, or ArchiMate to articulate architectural intent.
• Extensive experience in **architectural trade-off analysis**, capable of making informed decisions balancing performance, maintainability, cost, time-to-market, and other dimensions.
• Experienced in creating and maintaining **Architectural Decision Records (ADRs)** and fostering a culture that values design documentation and traceability.
• Understands and can formulate **architecture principles and design standards**, guiding team design direction through principles rather than micromanagement.
• Proficient in **C++**, with experience in low-latency network programming and performance optimisation.
• Proficient in **Java** and the **Spring Boot/Cloud** ecosystem, familiar with microservices design and containerised deployment.
• Deep understanding of the FIX protocol, with experience in developing or integrating FIX gateways.
• Familiar with MT4/MT5 communication protocols and management APIs, understanding their performance bottlenecks and optimisation strategies.
• Deep expertise in AWS, familiar with compute (EC2/EKS), networking (VPC, Direct Connect), storage, and messaging services (MSK/Kafka, SQS).
• Familiar with Linux kernel tuning, network latency analysis, and the TCP/IP stack.
• Experienced with real-time stream processing architectures and production-grade deployment of message brokers like **Kafka** or Pulsar.
• Familiar with the use cases and trade-offs of relational databases (**MySQL**) and NoSQL/OLAP databases (e.g., **StarRocks/ClickHouse**).
• Excellent written and verbal English skills, capable of reading technical documentation fluently and collaborating with overseas teams.
