Algorithmic Trader - Systematic Desk

# Algorithmic Trader - Systematic DeskAnnual base salary: £195,000 - £230,000 GBP Role overviewWestren Capital is a London-based proprietary trading firm specialising in digital asset markets. Our systematic desk designs and runs high-frequency and mid-frequency automated strategies across centralised and decentralised venues, competing directly on execution speed, signal quality, and infrastructure.Traders on this desk work across the full stack of a strategy, from signal to execution to live risk management, rather than handing pieces off and hoping they reassemble correctly downstream. Responsibilities -Design, test, and deploy systematic trading strategies across digital asset venues, with a focus on strategies that hold up outside the backtest -Monitor live strategy performance continuously, distinguishing genuine signal decay from noise, and normal drawdown from something actually broken -Work directly with engineers to improve execution logic, reduce latency, and close the gap between theoretical and realised fills -Manage position sizing, exposure limits, and risk controls across a live, automated book -Investigate anomalies in fills, slippage, or venue behaviour as they happen, not after the postmortem -Contribute new strategy ideas backed by evidence rather than conviction alone Requirements -Demonstrated experience building or trading systematic strategies, ideally in HFT or other latency-sensitive environments -Strong programming skills in Python and/or C++, able to move from research code to something that survives live markets -Solid understanding of market microstructure, order book dynamics, and execution mechanics -Comfortable owning a strategy end-to-end, including the unglamorous parts that break first if ignored -Experience in crypto or other 24/7 markets is an advantage given the operational demands of always-on trading -Calm, methodical approach to debugging live issues under time pressure
