Role Summary
Wagglyn is seeking a hands-on Chief Technology Officer to take full ownership of our trading technology platform as we move into production.
This is an end-to-end role: from architecture and system design through to live operation and continuous optimisation. You will be responsible for building, scaling, and operating a low-latency FX trading platform in a production environment.
We are looking for an experienced operator - not a pure architect - who has built and run trading systems under real market conditions and is comfortable taking full accountability for outcomes.
You will join a small, high-performance team with a clear mandate to deliver institutional-grade trading infrastructure from the ground up.
Responsibilities
System Ownership
* Own end-to-end architecture across trading systems, from execution layer through to infrastructure and data platforms
* Ensure systems are robust, performant, and production-ready from day one
* Take full responsibility for reliability, latency, and operational stability in live trading environments
Trading Infrastructure
* Design and operate execution systems, market data pipelines, and connectivity to FX ECNs and trading venues
* Oversee FIX session architecture, order entry workflows, and post-trade flows
* Build multi-venue, connector-based trading infrastructure
Platform & Infrastructure
* Define architecture for data ingestion, storage, and processing, including QuestDB and PostgreSQL
* Own Linux-based systems architecture, performance tuning, and infrastructure design
* Design for resilience: failover, recovery, retry logic, and observability
* Ensure secure, production-grade infrastructure including backups and business continuity
Team & Engineering Standards
* Build and lead a high-performance engineering team (target 2–5 engineers)
* Set engineering standards across performance, reliability, security, and release discipline
* Establish clear separation between hot path and control plane in system design
Required Experience
FX Trading Systems (Essential)
* Direct experience building and operating trading systems in electronic FX markets
* Strong understanding of market data, execution, order lifecycle, and real-time trading constraints
* Prior experience in a hedge fund, proprietary trading firm, or startup trading environment
Low Latency Engineering
* Deep expertise in Rust and C++ systems design for performance-critical environments
* Experience building low-latency distributed systems with efficient inter-process communication
* Strong understanding of concurrency, shared-memory IPC, and performance optimisation
Systems & Networking
* Linux specialist with strong knowledge of systems and network performance
* Deep network-aware systems thinking, including latency implications of routing, switches, and cross-host communication
Architecture & Reliability
* Strong knowledge of FIX protocols and trading workflows
* Proven experience designing resilient systems with failover, recovery, and monitoring
Communication & Engineering Discipline
* Effective communicator, able to work across engineering, quantitative, and business stakeholders
* Strong discipline around maintaining accurate, up-to-date codebases, documentation, and data schemas
Preferred Experience
* Experience building trading platforms from early-stage through to production scale
* Ability to bring or rapidly assemble a high-quality engineering team
* Familiarity with hardware-level optimisation (e.g. NUMA, kernel bypass, FPGA)
Profile
* Hands-on operator with full ownership mindset
* Comfortable working in a small, high-accountability environment
* Pragmatic and delivery-focused, with strong attention to system integrity
* Calm and effective under production pressure
Location
* Remote (global candidates considered).
Compensation
* Competitive and aligned with senior technology leadership roles in electronic trading.
