City Of London / Global
Overview
Lead Crypto Software Engineer – Front-Office role in the Digital-Markets Group, London (5 days on-site). Package to £180k + bonus.
About the firm
For ten years this boutique digital-asset powerhouse has been laying the tracks that institutional money runs on. Its three engines:
Active hedge-fund portfolios – senior traders running high-conviction, alpha-seeking strategies.
Multi-asset index business – bridging equities, crypto and gold with fully transparent benchmarks.
Capital-markets & treasury unit – building ultra-low-latency trading tech and providing execution across all desks.
Revenue is climbing fast and the trading floor now needs a hands-on Lead Engineer to spearhead brand-new builds.
Responsibilities
Front-row seat on FX, equities, commodities and crypto flows – no bonds, no credit.
Code 70 % of your week in Python 3.12 and Go 1.22; dip into C++/Java when micro-seconds matter.
Tackle venue gateways, market-data ingestion and order-routing at serious scale.
Direct succession path to Head of Engineering.
Decisions made in minutes; prod releases in days.
High-end compensation: strong base, bonus and full benefits.
Day-to-day
Design and ship green-field low-latency services for pricing and execution.
Remain hands-on while guiding a tight squad of engineers.

Champion automated testing, observability and airtight security.
Qualifications
Front-office / buy-side experience in FX, equities, commodities or crypto.
Deep expertise in Python or Go, plus working knowledge of C++ or Java.
Proven record building exchange-connectivity or execution-flow systems.
Delivery focus – comfortable smashing blockers and tight timelines.
