leading proprietary trading firm with an entrepreneurial and innovative culture at the heart of its business. We value
quick-witted, creative minds and challenge them to make full use of their capacities.
As a Senior Research Engineer, you will be responsible for helping to lead the development of our trading model research framework
and using it to conduct research to develop models for trading in production. You'll expand the framework to become global

Flow Traders is looking for a Senior C++ Software Engineer to lead the next-generation architecture of the market data and execution platforms that power our fully systematic trading. We don't treat market data as plumbing - for us it's a source of alpha, where feed handling, order book construction, and a deep understanding of exchange microstructure are themselves a competitive edge. We're looking for a senior individual contributor who has lived this philosophy in a proprietary or systematic trading environment and can squeeze every nanosecond out of the path from wire to strategy. As a senior individual contributor, you'll help set the technical direction for the Core Platform that underpins quantitative research, pricing, strategy development, and execution across hundreds of venues - and drive its global rollout across our Market Data, Quant Research, Pricing, and Strategies groups. You'll work in a tight, iterative loop with quants and technical traders, applying deep expertise in modern C++, OS internals, CPU and memory architecture, lock-free concurrency, and low-latency networking to push our systems toward state-of-the-art performance, robustness, and observability. WHAT YOU WILL DO: * Lead the development and global rollout of our Core market data platform used across multiple focus areas (Market data, Research engineering, Pricing, Strategies). * Design and implement high‑performance components for market data ingestion, normalization, and distribution, as well as its usage for order execution and strategy infrastructure. * Develop tools and frameworks that enable quants and technical traders to build, tune, and deploy data‑driven systematic pricing and trading strategies. * Own the full lifecycle of your components in a fast‑paced, iterative environment: deploy, monitor, profile, and optimize your code in production. * Work closely with focus group engineers, quants, and technical traders to refine requirements, collect feedback, and iterate on the platform's design and implementation. WHAT YOU NEED TO SUCCEED: * BSc, MSc, or PhD in Computer Science, Mathematics, or a related field. * 7+ years of post‑graduation professional C++ software development experience. * Experience building low‑latency market data ingestion, order execution, and algorithmic trading systems (proprietary trading industry preferred). * Strong knowledge of algorithms and data structures. * Experience in parallel, asynchronous, and multithreaded programming. * Demonstrated ability to write clean, reliable, and highly scalable C++ code. * Interest in extracting maximum performance from available hardware and software (CPU caches, memory layout, networking, etc.). * Ability to communicate effectively with both technical and non‑technical colleagues.

ABOUT THE ROLE AND TEAM The Technical Bid Manager will lead Quantum Motion's end-to-end bid activity for non-dilutive funding, collaborative R&D programmes, strategic innovation opportunities and selected public/private funding submissions across our global footprint, with particular ownership of the technical content, evidence and narrative within submissions. This is a hands-on role for an experienced bid professional who can manage opportunities from horizon scanning, qualification and capture through proposal development, governance, submission, funder clarification, award/contracting support and handover to delivery. This is a rare and exciting opportunity to be an early employee at a scale-up shaping the future of quantum computing. There are vast opportunities for professional growth and to make an impact within the company. Working closely with technical, product, finance, commercial/legal and leadership teams, you will turn complex quantum computing and semiconductor R&D into clear, compelling, funder-ready proposals. You will be comfortable shaping and reviewing technical inputs for coherence, completeness and evaluator alignment, while relying on subject-matter experts for technical sign-off. You will be highly organised, commercially aware and confident managing senior stakeholders, external collaborators and concurrent deadlines across the UK, Europe and Spain, with knowledge of US and Australian funding landscapes a strong advantage. Quantum technology knowledge would be valuable, but proven experience in bids, grants and proposal delivery is essential. OUR TEAM Since 2021 our team has been listed every year in the “Top 100 Startups worth watching” in the EE Times in 2021 and 2022, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors, and we have recently closed our Series C funding of $160 million. We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology. Our team of 100+ is based across London, Oxford, San Sebastián and Sydney, with our primary hub in Islington (London).
