Trading System Architect

Global Technology @ Berenberg

In an era where digitalisation and modern IT infrastructure is revolutionizing banking, we are shaping a technology-driven bank in which you as an IT professional will work closely with our business units. Our technology teams offer you an environment that will present you with exciting challenges - be it through the support and further development of legacy systems or the introduction of modern technologies such as AI, machine learning and highly automated trading applications.

Our Technology department of around 300 employees works largely in an agile way using a Scrumban approach and covers areas such as Cloud Computing, Cybersecurity, Operations, Process and Governance, Software Development and Architecture. We are particularly proud to develop almost all of our applications in-house, which gives us unique flexibility and innovative strength. Our tech stack includes modern technologies such as Java, Kotlin, TypeScript and Python, CI/CD pipelines, containers, Kubernetes as well as Azure Cloud, Azure SQL Database and Oracle Database with PL/SQL.

Your Role in the team :

We are embarking on a multi-year project to revamp a large part of our equity trading technology stack. This greenfield project will involve designing and implementing new systems, such as pre/post-trade risk engines, market data distribution, reference data handling, and the build-up of trading gateways, while also aligning with the modernisation of Berenberg’s proprietary Order Management System (OMS). The new system will run on Berenberg’s bare-metal Kubernetes (K8s) infrastructure.

This is an exciting opportunity for a Trading System Engineer / Architect with significant hands-on experience to join a delivery-focused environment. You will play a critical role in the system design and implementation of Berenberg’s new Cash Equity and Electronic Execution Platform. The platform must deliver 24/5 availability, bespoke trading workflows for demanding clients across multiple trading desks, and dynamic scalability to handle sudden increases in trading activities.

What will you do?

• Contribute to the design and implementation of Berenberg’s new Cash Equity and Electronic Execution Platform.
• Ensure the system supports global equity market trading with high availability.
• Develop bespoke trading workflows tailored to clients across multiple trading desks.
• Design and optimise systems to dynamically scale in response to market events such as interest rate decisions or breaking news.
• Collaborate closely with other IB Engineering teams and project members.

Who are we looking for?

• Solid software engineering experience (minimum five years) with expertise in modern software design, architecture patterns, and performance measurement (throughput, latency, capacity).
• Strong proficiency in Java, particularly in high-performance, low-latency, and microservice designs, with experience in real-time trading applications.
• Comprehensive knowledge of trading systems, including integration with reference and market data systems, ideally within equity trading using OMS or EMS.
• Experience with Kubernetes, container technologies, automation, and familiarity with additional programming languages like Go or Rust.
• A proactive mindset with excellent problem-solving skills, attention to detail, and a collaborative approach, alongside knowledge of agile environments and regulatory considerations.

What we offer you:

• Private pension plan - 10% of base salary contribution by Berenberg
• Private Health Insurance
• Enhanced parental leave policies
• Employee Assistance Programme offering counselling sessions related to mental health, financial wellbeing and other topics
