Senior C++ Low-Latency Developer

About this role

RNDpoint (4ireLabs) is the staffing partner; end client is Millennium — a US-based, top-3 hedge fund (do NOT name in outreach). This is a headhunting search (not a volume play) for a Senior C++ Low-Latency Developer. Poland was tried extensively (~15-20 submissions, only 1 offer; other outstaffing firms also failed there) and is now considered exhausted — pivoted to UK (primary) Netherlands France. Fully remote, 12-month contract convertible to full-time. Pipeline is empty (project created 2026-08-05); no progressed-candidate signal exists yet, so this toolkit is domain-derived rather than mirror-of-liked-profiles.

Ideal candidate

A senior, hands-on C++ engineer (~6+ yrs) who writes the low-latency hot path for automated/electronic trading. Modern C++ (C++17 minimum, C++20 preferred). Ideally direct market-data experience (feed handlers, ticker plant, FIX, order book). Pedigree from a proprietary trading firm, market-maker, HFT shop, investment-bank e-trading desk, or systematic hedge fund. Based in the UK (best), Netherlands, or France; comfortable with a fully-remote 12-month contract convertible to permanent. Motivated by the technical challenge / wanting more cutting-edge work rather than by pay.

Required

Senior C++ specialist with genuine low-latency experience (C++20 ideal, C++17 minimum)

Background in traditional trading firms / hedge funds / investment banks

Based in UK (primary), Netherlands, or France — NOT Poland (market proven too thin/rejected on country+bar, never on rate)

Comfortable with fully remote work; open to a 12-month contract structure (converts to FT after 12mo by mutual agreement)
