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:

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.

• 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.
• Pair with traders to prototype, test and deploy new strategies at speed.
• 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.
