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.
  • 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.
  • Leadership across architecture, SDLC and developer mentoring.
  • Willingness to be in the London office every day.
  • Seniority level: Mid-Senior level
  • Employment type: Full-time
  • Job function: Information Technology
