Arindam Paul | Senior Quantitative Developer — Exchange Connectivity, Low-Latency Trading Systems, C++ Java

Who I Am

I am a senior quantitative software engineer who builds the systems that sit between trading desks and global exchanges. For the past decade, my work has been in the most demanding corner of software engineering: low-latency market-making infrastructure where microseconds translate directly into revenue, and reliability is not a feature but a prerequisite.

I am not looking for a job. I am selectively considering the right opportunity with the right firm — one where deep technical expertise in exchange connectivity, trading infrastructure, and real-time systems is valued at the level it deserves.

What I Have Built

Goldman Sachs Reconciliation System Designed and delivered the full reconciliation system for Goldman Sachs at IMC Financial Markets, covering 630+ securities. Took the project from inception to production in four months.
ETF Trading Desk Launch Built the technology stack that launched an entirely new ETF trading desk at IMC. Three months from zero to live trading.
90+ Exchange Venues Connected Eight years of building and maintaining exchange connectivity across 90+ global venues at IMC — the low-level protocol work that keeps a top-three global options market maker trading.
Apple Music Classical Built the music metadata database at Primephonic that became the foundation of Apple Music Classical when Apple acquired the company in 2021.
2 US Patents in Healthcare IT Invented and patented emergency radiology workflow systems that reduced critical case response times and are in production use today.

I build systems where failure is measured in millions per hour
and success is measured in microseconds.

What I Am Looking For

I am selectively exploring senior and principal-level roles in quantitative finance, trading technology, and exchange infrastructure. The right opportunity combines deep technical challenge with genuine impact — building systems that matter at firms where engineering excellence is a competitive advantage, not a cost centre.

I am particularly interested in opportunities in Singapore, Dubai and Abu Dhabi, Hong Kong, New York, and Chicago — though the right opportunity anywhere merits a conversation.

Target Markets & Firm Types

I am looking for roles at prop trading firms, market makers, hedge funds, sovereign wealth funds, and investment banks that build exchange connectivity, order management systems, market data infrastructure, and low-latency execution platforms. My experience with FIX protocol, proprietary binary exchange protocols, and multi-venue connectivity across 90+ global venues — including CME, Eurex, ICE, NYSE, OPRA, and dozens of APAC and emerging market exchanges — translates directly to firms expanding into new venues and asset classes.

Global Mobility

I have lived and worked on four continents. Relocation is not a barrier — it is a feature of my career. I am available for relocation within 4-8 weeks of a signed offer.

Singapore ONE Pass eligible. APAC exchange connectivity experience (SGX, HKEX, ASX protocols). IMC and Flow Traders both operate Singapore desks — familiar with the APAC trading ecosystem.

Dubai & Abu Dhabi UAE Golden Visa ready — meets qualification criteria for specialised talent. 0% income tax. Middle East exchanges (ADX, DFM, Tadawul, DGCX) are modernising — 90+ venue connectivity experience is directly relevant to Gulf market infrastructure buildout.

Hong Kong Top Talent Pass eligible. HKEX connectivity experience transferable from European venue work. Jane Street, Citadel, Jump all operate HK desks.

New York & Chicago Prior US work history (Milwaukee). CME, ICE, NYSE Arca — venues I have connected to from the other side. O-1A visa pathway supported by 2 US patents and Apple Music Classical contribution.

Netherlands Currently based in Amsterdam with full EU work authorisation. Available immediately for Amsterdam-based roles at IMC, Optiver, Flow Traders, or other Dutch prop firms.

United Kingdom Cambridge University mentor. Established London professional network. Global Talent Visa eligible under Exceptional Talent route (2 US patents, 20+ years).

Technical Depth

My primary language is Java, used at production scale in low-latency environments where garbage collection tuning, off-heap memory management, and JVM performance engineering are daily concerns — not abstractions. I work fluently in Kotlin and Python. My infrastructure experience spans Kubernetes, AWS, GCP, Docker, Spring Boot, and PostgreSQL. I have implemented FIX protocol and proprietary binary exchange protocols across dozens of venues. I have built systems that process tens of thousands of messages per second with deterministic sub-millisecond latency — ring buffer architectures with zero allocation on the hot path, NUMA-aware memory management, and lock-free data structures for concurrent market data processing. These are not resume keywords. They are things I have shipped to production and operated under real market conditions.
